Game Progress Update #72

Game Progress Update #72

Hello world! And welcome to the seventy second Dev with Dave Game Progress Update! I feel like this last couple of weeks has been a little better than the last one.

There has still been plenty of unwanted drama keeping me away from the keyboard, but I have managed to get a bit done to the game. I’m starting to think I should give up my career as a developer to instead write for the soap operas.

I even had to contend with Trello going down while I was trying to finish this blog post! Which is most unusual. Anyway, lets have a look at what I did manage to get done this week..

Plan for this update

Carrying on from the last progress update, there are the following things to do in the In progress column of the Trello board this update.

  • Review phase 1 cards
  • Increase difficulty and rewards of daily missions
  • Level difficulty

There are only a handful of the review phase 1 cards left. These are ones which needed boosts to be unlocked and purchased first, which I didn’t have the coin for. This time round I will edit the game to award me several thousand coins. I couldn’t do this last update as I was away from the PC, playing the compiled version on my phone.

Review phase 1 cards

Once I had added the line which awarded the player 250,000 coins, it was straight forward to test the remaining phase 1 cards.

It only took an hour or so to play the game enough to have completed the last few cards. Well, to be honest, I probably could have done it in half the time, but the game is quite addictive, lol.

The cards were fairly straight forward to check. They were things like the head start not playing the shield sound effect, or purchasing or using boosts not changing the UI values accordingly.

I also made sure that I removed the line of code which award the extra coins for testing purposes, when I finished testing.

Increase difficulty and rewards of daily missions

Reading back over the code..

At first glance, it didn’t seem as though I had added much in the way of code to handle the progression of the daily missions.

There was a missionTotals[] variable, but there was nothing in the comments or the like describing what it’s purpose was. I had actually commented it’s definition, but nothing helpful about what I was intending to use it for.

A little digging later, and I found that in both the load and save daily mission data functions, I had referred to the variable in the comments as “the mission totals count”. It’s my belief that I had intended this array to store the number of times each daily mission had been completed.

No matter how many times I say about HOW VERY IMPORTANT commenting your code is, for exactly this reason; I still find myself causing extra work by not doing it.

Making some changes

Going from here, I added a second variable to the type which is to track the current level of each daily mission. The plan is that once the specific mission types Total has exceeded a set value, then the total is reset to zero and the level value is increased. The level value is used to determine the difficulty and reward of the mission.

added a line to the calculate the reward function for missions, which just times the level value by ten to get the reward value.

Changing the target value however, was a lot trickier. Each mission type has its own initial target value ranging from 1 to 50. Ideally, I need to write a function like the one which calculates the reward value. This would allow me to As I felt on a bit pressured for time, I am kludging it for now, by simply multiplying the initial value by the mission type level value. I can always revisit it in the future if the values need changing.

I need to get the test build uploaded so I can test this. In order to check the code works, I need to play the game for five days consecutively. (Unless I cheekily change the value, so I can check it later this evening once the roll-over has happened 🙂 )

I still need to verify that this all works, but that will take a few days unfortunately. So I won’t know the results until next week.

Level difficulty

I didn’t manage to get any coding related to this last card done this time round. I did however get some thinking done about how this will work.

The issue is that as the game speed increases, it makes some of the zones very tricky to get through. It can leave the game feeling as though the difficulty suddenly ramps up, disproportionately so at times. So the plan for this card is to devise something to lessen this effect.

I’m unsure if I want to implement any of the following methods to try and add a bit more playability to the game.,

  • create a system which adapts the levels by increasing the distance between obstacles slightly.
  • Create several new levels, and develop a system to separate slow and faster levels.
  • Tweak the existing levels so they work better with a wider range of speeds

Ideally I would like to create at least twice as many zones as there are already, to prevent the game from becoming too repetitive, too quickly.

GDD Update

As well as all of the above stuff, I took the opportunity of updating the GDD with all the changes which were marked in the completed cards I reviewed from phase 1.

There aren’t many changes. The biggest ones were relating to the daily prizes and missions. There are a few minor changes however as well.

That’s all for now

Once again I’ll be back in another fortnight with more news about the game.

I’m aware that I need to be working on the marketing strategy, especially considering how near to completion the game is. Aside from one video trailer I made, I’ve not really done anything on this apart from a few pages of notes. I’m not sure if I should include this in the progress update, or perhaps write a separate blog post about it. (Or maybe both, lol, who knows)

Anyway, I hope you’ve enjoyed reading this post. I’ll see you again in two weeks.

Game Progress Update #71

Game Progress Update #71

Hello World! And welcome to the seventy first Dev with Dave Game progress Update.

I’m sad to say that it’s been another of those weeks where nothing has gone to plan. I’m already two days late starting this blog post.

Unfortunately, my girlfriend’s diabetes put her in hospital again this week, so my available time to work on Flappy-vaders has been dramatically reduced. It doesn’t help that my car is off the road as well. So, I have had to be finding other ways of getting around.

Taxis are the easiest and quickest, but most expensive. We also have those Lime electric scooters and bikes around here, which are cheaper than taxis but are slower. They are great fun though. Lastly there are busses. Busses are slow and uncomfortable and take an age to get anywhere. They are cheap though.

I’ve also spent more time than usual simply walking places. I like walking, it gives me chance to listen to books on Audible and enjoy the scenery.

Anyhoo, lol, In the little time I have had spare, I have managed to get a little bit of work done on Flappy-vaders. Let’s dive into what’s been done since the last update, without further ado.

Reviewing Phase 1 Trello Cards

In the last Game Progress Update, I finished with one remaining card on the Trello “In progress” column. That was to review all the cards which had been completed and moved to the “Under review” column for evaluation.

The one solitary benefit of my girlfriend being in hospital was that I got to spend a few hours sitting in a waiting room playing Flappy-vaders and working my way through the cards on the column.

I won’t list the individual cards here, as I think that would be a little dull tbh. But feel free to check out the Trello board >here< and see for yourself.

The only ones I couldn’t verify were the ones which involved unlocking and using the boosts. As I was away from the computer and playing the compiled version on my phone, I couldn’t simply add more coins to my total so I could play it.

Planning Phase 2

I have also managed to get some work done on the planning for the difficulty increases as the player proceeds with the game. I’m already thinking 1000 coins is too much for the boost unlocks.

I’m planning on increasing the difficulty and reward for the daily missions as the player progresses through them. For example, the player would need to complete “Travel 25 distance” mission maybe two or three times, before the distance increases to 50 and the reward gets doubled as well.

I’d also quite like to tweak some of the trophy values. They have all been tested now, and the harder ones need to be made a little tougher.

And lastly I would like to at least double the number of zones, with new patterns for the obstacles and enemies.

That’s all for this week

I’m happy to announce that my girlfriend was discharged from hospital after a couple of nights stay. She’s not a hundred percent better yet, but I’m glad she’s home.

Work on the game will proceed as normal next time round hopefully, as I feel I have had more than my fair share of bad luck and interruptions.

In the next update I will attempt to look more deeply into the promotional strategy I will be using for the game, as well as trying to get on with making the Phase two changes to the gameplay.

5 Free Alternatives to Unity!

5 Free Alternatives to Unity!

After the Unity pricing fiasco of last month, a lot of Devs are still angry at Unity and have swore to switch to alternative game engines to develop their games with. In this article I am going to look deeper into five alternatives to Unity, all of which are free to get started with.

Unreal Engine

Unreal Engine 5 logo

Unreal Engine (Or just UE) is a big name in game development circles, and is probably Unity’s biggest rival. It has been used to make games like Fortnite, Batman Arkham Knight, Hollow knight and Borderlands.

As you can imagine, for a software with the scope of UE, it has a bit of a learning curve. It uses C++ to write scripts, which is not the easiest of languages to learn. But it does also have a visual scripting system called Blueprints. This allows you to create games using a more visual node based system.

Feature wise, UE is a heavy weight contender. It is packed with features like volumetric effects, Dynamic lighting, Advanced nanite landscaping system, a skeleton animation editor, and dozens of other AAA features.

It has been said that Unreal Engine isn’t particularly good for 2D projects. Whether this ever was true or not, it is certainly something that has got better with the more recent builds of UE.

There is a very active community for Unreal Engine. There are also lots of tutorials available for free on YouTube. Or, there are courses for sale on Udemy and the like.

Unreal is free to use. However, they ask for a 5% share of any income your game makes over the first $1 million dollars.

https://www.unrealengine.com/

Godot

Godot Logo

Godot is a free cross platform open source game engine.

It was initially designed by Juan Linietsky and Ariel Manzur. It was released in 2014, and runs on a variety of platforms and can compile to even more.

Godot uses Open GL as a renderer. With the latest version of Godot using Vulkan. It allows you to create 2D and 3D games using a range of different languages. As well as Godot’s own GDScript language, it allows you to use C++ and C#, or others which can be added using GDExtension.

It also has a very strong GUI system. It allows the user to easily create scalable UIs for any game or application.

Version 4.0 is the latest version of Godot. It boasts a range of new features as well as the Vulkan renderer which I mentioned earlier. It also has a handy movie maker mode you can use to record gameplay or cutscenes.

Because it is open source and free under the MIT license, Godot is free to use and will never charge you a fee for games written with it. Although there is the option to donate money on their homepage.

Like Unreal Engine, Godot has a huge community. As well as the official websites FAQ and Support stuff, the GitHub page for bug reports, there is social media channels and a discord server. Not to mention a whole load of community created user groups & free tutorials.

https://godotengine.org/

GameMaker

GameMaker Logo

GameMaker is the first one of the engines in this list which is 2D only. Despite this it’s a fairly capable cross platform engine which has created games like Hotline Miami on the Playstation.

It offers you two methods to create your game out the box. Firstly, You can code it using GML Code, a simple enough scripting language to get the hang of; Or you can use the GML Visual editor, a visual scripting method which uses action blocks to construct the game logic in an intuitive way.

It has it’s own physics system integrated into GML, and has Spine support for skeletal animations. It also supports shaders for effects and post processing.

There are an abundance of tutorials available free from the website, and on YouTube, as well as paid for courses on places like Udemy. There is a large and helpful community of developers.

Although GameMaker is free to learn and use, the only place you can publish to on the free package is the GX.games website. You need to take out a subscription before you can publish to any other platform.

The above table shows which platforms you can publish to with which subscription tier. It also shows the monthly price. The annual prices are 10x the monthly price, a saving of two months subscription.

https://gamemaker.io/

GDevelop

GDevelop logo

GDevelop is another free open source game engine. It doesn’t offer console export options, unlike the previous engines in this list. It does however give the option to make 2D and 3D games.

I wasn’t sure whether to include this or not when I was originally planning this list. GDevelop comes across as more aimed at beginners, but after some research I have discovered it’s quite a capable game engine.

The editor can run on a variety of platforms, including a specific iOS/Android app. It offers codeless game creation using events and behaviours. Although users can use Javascript to create code blocks which can be used in place of events. This also allows users to enhance their games by adding additional features to engine.

Out of the box it offers the expected array of features

  • Tilemaps.
  • Physics engine.
  • Pathfinding.
  • Platformer engine.
  • Dialogue editor (Yarn Classic)
  • Leaderboards.
  • Gamepad support.
  • Particle Emitter.

Although closer examination reveals that the physics engine is 2D only, as it is based on the Box2D physics engine.

One of the most novel features of this engine is that it offers cloud based Mac and iOS compilation. Meaning you can get your game published without owning Apple hardware. However, it’s not cheap and its only available using your own certificates on the most expensive business tier. I thought it was worth mentioning anyway.

https://gdevelop.io/

Defold

Defold logo

Defold is another open source cross platform game engine, and the last of the alternatives to Unity we will look at today.

It can develop both 2D and 3D games. Although it was developed as a 3D engine, it was created with tools to allow development of 2D as well. It uses a modular, component based system of game objects.

Defold uses Lua as a scripting language. For those who don’t know, Lua is powerful and lightweight scripting language which combines simple syntax with powerful data description constructs.

It has support for 2D physics based on Box2D like GDevelop, but also supports 3D physics using Bullet.

The Editor is quite flexible, allowing for the editing of animations, scenes, UI, etc. all in Visual environment. It also boasts about its compiled games having a much smaller file size compared to Unity or Unreal.

There seems to be a reasonable sized community, with a forum on the official website, and the usual tutorials and asset packs to start developers off.

It’s been used to create games like Family Island by Melsoft, which boasts an impressive 50 million downloads on the Google Play store.

Defold is another game engine which is totally free, regardless of how well your game performs in any market.

https://defold.com/

Conclusion

There we have it. Regardless of how you feel about Unity and their new usage fees, there are plenty of alternatives to Unity. I only included a small selection in this article, and obviously there are the paid for engines like App Game Kit Studio which I am building Flappy-vaders with.

For a more Unity like toolset, then UE is the one to use but does also charge a fee if your game exceeds certain thresholds. If you are after a simpler game engine, but one that doesn’t charge a fee then one of the open source options like Godot or Defold would probably suit better.

My suggestion would be to look at each website in turn and decide which engine would best suit the game you have in mind. As each engine on this list is free, there is nothing stopping you from downloading and trying them out first.

Game Progress Update #70

Game Progress Update #70

Hello world! And welcome to the seventieth Dev with Dave Game Progress Update!

It just occurred to me that when we reach the seventy eighth game progress update, that means I’ll have been working on Flappy-vaders for three years in real time. Since I’m only working on it part time, this equates to around a year, perhaps a year and a half of actual development time.

(I certainly wasn’t expecting this to take quite as long as it has when I began this journey! 😅)

We’re in the final stretch now, I really should be getting busy thinking about how I’m going to promote the game when it’s released (And before!), and designing, if not creating assets to use in the promotion.

I’ve not really thought much about promoting the game since Update 66. Which is when I last worked on the promotional video. (It’s >here< if you want to have a look)

This time round

I have moved three cards into the In Progress list on the Trello board.

  • Add a back button to the daily prize awarded screen
  • Make icons for the Daily Missions screen
  • Review phase 1 things in the Under Review list.

Add a back button to the Daily prize awarded screen

I was hoping this would be a simple case of adding a UI element to the existing UI page when I selected this task off the Things to do list on the Trello. But when I checked the UI pages I couldn’t see it.

I had a look again at the screen in action, and saw that it appeared to be a sprite overlay, rather than a UI page, as the scratcher UI page is visible underneath. This rules out my original fix, and means it’ll probably take a lot longer to sort out. 😞

After some investigation, I found where the code for the overlay sprite was being called from. It was a straight forward job to pass the function a reference to the UI and add a back button. This code could hide and show at the same time as the sprite overlay. All I’d need to do is ensure that the button’s draw depth is above the overlay panel.

With that in mind, I set off the the UI script to find a back button from an existing page to copy and paste onto the scratcher page.

Except.

There aren’t any? All the other UI pages just use the “Left facing triangle” icon in the top left corner of the screen.

I’m not sure why I thought the game needed a back button on this particular screen, but it seems to break continuity of the UI design to add one. Because of this, I have decided not to it after all.

Make icons for the Daily Missions screen

A bit of an oversight perhaps, but I noticed the Daily missions screen had only grey boxes instead of icons. Fixing this was added to the Phase 2, the polishing phase.

There are I think, five types of Daily Mission. Each one needs it’s own icon to represent it.

  • Score x amount of points
  • Travel x distance
  • Collect a daily prize
  • Play x number of games
  • Collect x coins

Initially I sat down at my desk with some paper and a pencil and started thinking. Some of the icons were obvious to me. I could simply reuse a coin icon from another menu, for example.

Even with the limited 22 x 22 pixel size, It didn’t take long to create the several of the icons.

Traveling distance however, was proving to be quite a challenge. I couldn’t think of a single concept or idea to represent traveling distance which would fill the tiny grey square.

I finally ended up using ChatGPT and Bind AI Image generator to help me come up with some ideas. You can read all about my experience using AI in this blog post.

The image above shows a few of the icons I created in place in the Daily Missions screen. The bottom one is the travel distance Icon which I had difficulties with. Until ultimately I sought the help of AI.

Review completed tasks from Phase 1

With the other two tasks out the way. It meant I had chance to review some of the cards in the Under Review list on Trello.

This meant I had to sit for a few hours with the Trello open, playing Flappy-vaders! It’s a tough job, lol, but someone has to do it.

I quickly got into a habit of reading the next card, and having a turn at the game. Fortunately the first few cards were easy enough to check in a single game.

Overall I think I managed to move 15 cards from under review to the completed list. At least before it was time to finish the blog post and do all the social media as well! lol

There are still loads of cards to verify, so I expect I’ll still be doing this next week. A lot of them mean editing the game so I have enough coins to buy unlocks and powerups so I can test some of the other cards.

That’s all for now

That’s all I have time for now I’m afraid.

Sorry the social media posting has been a bit sporadic the last few weeks. Other things have been getting in the way. Sadly real life things which I can’t just push to one side.

I will definitely be back in a fortnight, and I’ll try and do a better job with the social media stuff 😊

Until next time..

Using AI as a Game Developer

Introduction

There has been lots of talk about AI recently. From the tinfoil hat wearing doom mongers, to those who think it marks the next age of human civilisation, and everyone in between. In fact, it’s hard to go online these days without stumbling across posts relating to AI.

With that in mind, I thought I would tell this short tale about how I used AI to help me in my work as an Indie Developer.

Flappy-Vaders

As many of you know, I am writing a game called Flappy-vaders in my free time. I share progress updates every two weeks, here on the blog.

The other day I was sat working on the game during a spare hour or two. I was trying to create some icons to represent the different daily missions. Apart from a couple of pencil sketches, I really had no clue as to what they should look like.

It’s fair to say I am a programmer, not an artist. I was having a very frustrating time trying to convert the various concepts to images. Time was ticking on, so I thought I would try see if using AI would help any.

What is ChatGPT?

I’m sure you are all aware of OpenAI’s ChatGPT. It’s a large language processing AI model, which can understand and reply to queries using human language.

It can do things like write essays or blog posts, find formulae, write poems or other creative stories, research a topic and provide a summary of the information, and even write code!

Hello ChatGPT.

I’d used ChatGPT previously for another unrelated task, so I didn’t need to create an account. I could just log into my existing one.

The above picture is the conversation I had with ChatGPT, where I explained what I needed help with. Then I narrowed down the scope of the task by asking for a specific concept.

I asked it to help me with an icon to represent distance, for the distance travelled daily mission.

ChatGPT replies more or less in real time. You can watch the text appear on screen as though it is typing to you. It didn’t take long before it had given me a list of seven ideas which all seemed to fit the requirements.

I narrowed the selection down to just two ideas, and was about to reach for my pencil again when I wondered whether AI could help any further with the task.

Bing AI Image Generator

The next AI tool I tried was the Bing AI Image Generator, which is another free to use tool.

Unlike ChatGPT, which provides you with text as an output, the AI Image Generator outputs images. So I entered the two suggestions I was considering from ChatGPT.

Suggestion 1 – A road or pathway stretching off into the distance

The first one was a road or pathway stretching off into the distance. However, I didn’t specify the size of the icons with this first prompt.

I was suitably impressed with the first round of images. particuarly the bottom left image, although the background wouldn’t translate to pixel art very well.

I tried again, using the same prompt but using the term “small icon” rather than “icon”, and after a minute or got this second batch of images.

Again the designs were quite good. The general image of the road snaking off into the distance is strong in each of them.

I’m not sure however that the curves of the sweeping road would translate very well to the 22 x 22 pixel square image I need for the UI in the game.

I decided that didn’t need to refine this design further. So I moved on to the second one of the ideas I had shortlisted from the ChatGPT output.

Suggestion 2 – Two points or pins connected with a line

Next I tried the other option which I liked from the ChatGPT output. This was “Two points or pins connected with a line between them”.

It didn’t take a terribly long time for Bing to once again supply me with four images which it had generated from the prompt I had given it.

As soon as I saw the output, I knew that this was the one which I would use in the game.

The familiarity of the Google Maps style pin clearly conveys that the icon is representing travelling between the two point. This is exactly what I needed for the “Travel n Distance” daily mission.

I still however had to try and get the image to fit into a 22 x 22 pixel square.

I opened up Paint .Net and set to work on creating the icon.

The finished icon

The finished icon is shown in the screenshot below. I don’t think I did too bad of a job making the elements of the icon recognisable at the size it needed to be.

Overall, from the time I decided to open ChatGPT to the time I closed Paint .Net and added the icons to the media folder of the game, it took about 3 hours. Most of this time was me being overly fussy about tweaking the images in the art package.

Conclusion

I am in no doubt that there is no danger of humanity being replaced by AI anytime soon. It does however make for a very valuable tool for researching a topic, or for providing inspiration for graphical design.

I didn’t use it to generate any code however. I am aware that it can write code, but it’s best to view it as pseudo code as it is quite often error filled or generally incorrect.

I really do think that using AI for the simple task described above has saved me literally hours of time sketching and scratching my head. I am definitely going to look for more ways I can use AI to streamline my game development process.

The Unity Runtime Fee Fiasco

The Unity Runtime Fiasco

Unless you live under a rock, you’ll have noticed that the Game dev world was sent into disarray when Unity announced a new pricing scheme.  I certainly couldn’t help but notice as all the Game Dev Facebook groups were full of people disowning Unity and telling the world that they are switching to Unreal Engine or Godot. Even the news had headlines about Unity’s share price plummeting.  But what was it all about?  What had Unity done?

Unity announced earlier in September that they were changing their pricing to include a per install Unity runtime fee. This greatly upset a lot of developers who were very vocal about it on social media. Unity issued an apology, and then a short time later, a statement containing a revised pricing plan as well as addressing some of the concerns users had.

What did Unity do?

On 12/9 Unity shared this post on their blog about a new Unity Runtime Fee.  It explains that Unity is made up of two parts, the editor, and the runtime component.  The runtime component is the code which runs your game on the players device.

It’s this runtime component that Unity wanted to introduce a fee for each time it was downloaded, once a game had exceeded some thresholds relating to earnings and number of downloads.

Unity stated they believed a flat fee per install was fairer than taking a percentage of revenue as other game engines do.

They did not however explain which versions of Unity run time would be affected, leaving users angry that it had been applied retroactively, possibly costing developer millions in owed fees.

Nor did they explain how data regarding the thresholds would be collected.

Public outcry

A screenshot of a social media post from Brackeys in response to the Unity Runtime fee

The news spread all across the gaming industry like wildfire. It didn’t take very long before all the social medias were alive with posts from outraged indie developers who felt betrayed by Unity.

People were upset and confused by the announcement.  Many smaller developers were worried if this would have affected them.  In many of the Game Developer groups I follow, every other post seemed to be “I am leaving Unity and moving to Godot” or “I am quitting Unity and am going to use UE from now on”.

Even Unity Celebrities like Brackeys have made posts condemning Unity for the way it’s treated its customers.

So big was the fall out from Unity’s announcement that the news spread far beyond just the gaming world.  It even affected Unity’s share price, which dropped 12% in the days following the announcement.

Unity’s reaction

It only took five hours before Unity started tweeting out in defense of its new policy.  Offering explanations and reassurances that these new changes would only affect a small minority of developers.  They answered many of peoples questions on their forum online. 

A screen shot of a tweet from Unity saying that they have heard the users and will issue an update soon

However as the onslaught continued, Unity finally tweeted that “they had heard” the voices of concern from the public.  They also said that they would share an update again the a few days.

Although this news didn’t quieten the online discontent. It did start a lot of speculation as to what Unity would do instead. Ranging from scrapping the idea of a fee altogether, to charging a 5% flat fee of the games earnings.

A change of heart

Then ten whole days after the drama started, Marc Whitten from Unity, shared an open letter to the community.

This letter started with a heart felt apology, and acceptance that they should have spoken to the community more about the changes they wanted to implement.  He explained that the new charges were to ensure that they could support users. As well as to invest in keeping Unity up to date with the latest technologies.

He went on to say he realises how important the Unity users are to the company. And that they will work hard to earn back the users trust.  The letter then goes on to describe what changes have been made in Unity’s revised plans.

How does the new Unity Runtime fee work?

Their latest update clarified that the Runtime fee will only apply to games made with the next LTS release of Unity onwards.  This is due to be released in 2024.  This addresses one of the biggest concerns of the users. That this fee would be applied retroactively to existing published games.

If a game exceeds some thresholds relating to number of downloads and income generated, the developers will be given a choice to pay either a 2.5% of revenue share, or a calculated amount depending on the number of active monthly users.  Both these values are obtained from data you provide to Unity. You will always pay the smaller of the two values.  This also addresses another large concern from developers. That Unity would be using their own analytics to provide data used to calculate the fees unity would charge.

What are the thresholds

Before you are charged the Run time fee for your game, it has to exceed two thresholds.

The first one of these thresholds is on the number of downloads the game has had.  It has to have more than 200,000 downloads since it was published.

The second one relates to the income that your game generates.  To exceed the second threshold, your game needs to have earned more than $200,000 in the last 12 months.

So, in order to be eligible for the fee, your game must exceed both these thresholds and be made with a Unity version after the next LTS version.

However, if you do exceed these thresholds, you can always upgrade to Unity Professional. This will increase the thresholds to 1,000,000 downloads and $1,000,000 respectively.

Other changes Unity have made

With the next version of the LTS Unity and the Run Time fee, Unity are also adding cloud-based asset storage, Unity DevOps tools, and AI this November.

They are also removing the requirement for games made with the free Unity accounts to show a made with Unity splash screen when loading.

This is good as they have removed the Plus level account, which had no splash screen requirement.

Resignation

Shortly after I originally published this article, John Riccitiello, the CEO of Unity has resigned from both his position as Chief Executive Officer, and the board of directors of the company.

He had joined the company back in 2013 after resigning from his position as Electronic Art’s Chief executive.

Mr Riccitiello said “It’s been a privilege to lead Unity for nearly a decade and serve our employees, customers, developers and partners, all of whom have been instrumental to the company’s growth,”.

No reason was given for his resignation.

Conclusion

Although I think that Unity really dropped the ball with their initial announcement, I think they have made a reasonable compromise and have satisfied most of their userbase with their revised plans.

Its good to see that they do listen to their users, and hopefully they have learned a valuable lesson from this fiasco.

Unity is one of the largest game creation tools, I doubt very much that it would simply disappear due to one mistake.  Far too many studios have invested hundreds of thousands of dollars into developing games with Unity for them to just switch tools mid way through a project.

I hope that my next Unity game beats both the thresholds and becomes eligible for paying the Unity Runtime Fee! Lol.

Game Progress Update #69

Game Progress Update #69

Hello World! And welcome to the sixty ninth Dev with Dave Game Progress Update.

It seems I am still having to put in an extra hour a day at least playing “Dad’s taxi” and dropping off the kids places when I would rather be working on Flappy-vaders.

Or at least I was until yesterday, when the car broke down on the side of the road. *sigh*

It’s probably going to be at least a week till I can get the car looked at, which is unfortunate. But at least it means I have fewer excuses for not working on the game! lol.

Let me tell you about what I have done this update.

Stutter during gameplay

The last Known bug/issue card in the In Progress column on the Trello was Stutter during gameplay.

This card was added to the Known bugs/issues column on the 1st march 2023, so it’s a fairly recent issue. It does specifically say on the card that the issue occurs on mobile during testing.

I have a feeling that this was relating to some screen settings which I altered a while back when I noticed that the game was running at 120fps on the Android test device I was using.

I spent several hours testing for this, (Does this really count as work? lol.) And unfortunately I have been unable to replicate the issue. The test team have also put a few hours into playing the game and haven’t mentioned any stuttering.

It definitely still happens on the PC, but as the game is targeted for mobile, I am going to mark this card as finished, and move it over to the Under Review column.

Phase 2

Having completed all of the initial stuff, by all accounts I should warrant some kind of celebration, followed by a break. But I feel like the project has taken too long as it is, so instead I’m going to dive straight into Phase 2.

Phase 2 is what I call the next step in the games development. Now all the systems are working as intended, it is time to work on developing the longevity of the game.

Although Flappy-vaders is designed to be played casually, in short bursts while waiting for the bus, or the microwave. There are aspects to keep players returning to the game. The upgrade/boost stores, the trophies, the prize scratchers etc.

I want to add a system to increase the difficulty of the challenges for the daily missions. As well as the rewards after the player has completed a few missions. This will have maybe five grades of difficulty/reward.

I also want to add timers to the reward ads and buttons. These are to limit the number of times the player can get a free daily scratch card.

I also want to ensure that the trophies are balanced. Currently I feel that they are all achievable too quickly.

Lastly there are a few changes I have decided to make to the UI.

I have added all these cards to the Trello, and assigned a couple to the In progress column.

First Phase 2 card completed!

Apparently I had the Fix bugs in Known bugs/issues column as a card in the Things To Do as part of Phase 2, lol.

As I have spent the last several weeks working through the list of bugs, and fixing them all, I think I can mark this one off as completed.

They all still need reviewing, and moving over to the completed column. But that’s a job for another day. I have created a card in the Trello for it.

Another test version uploaded

As all the bugs (That I was aware of anyway) had been fixed, it seemed like an ideal time to compile and upload a new version to the store.

If you already have Flappy-vaders installed, then it will automatically update soon. If not head over to the store page and update it from there.

That’s all for now.

As always I will be back in two weeks with the next update. Hopefully I will have a couple of phase 2 items crossed off the list.

If you want to join the test team, then its not to late. Just drop me a message on any of the channels, or simply email. I’ll get back to you soon.

Until then..

Dave 🙂

Game Progress Update #68

Game Progress Update #68

Hello world, and welcome to the sixty eighth Dev with Dave Game Progress Update.

It’s not been the best couple of weeks for working on this. As you all know, I am doing it in my spare time, and unfortunately my girlfriend is once again laid up with a bad back. Which means that I have not had anywhere near as much free time as I would have liked.

Combine that with running “Dad’s Taxi” for the children who seem to have had an abundance of appointments, and you’ll end up with a slightly stressed Dave who hasn’t had much chance to work on Flappy-vaders.

Throw in a week of ridiculous weather as well, and you start to get an idea of how this last two weeks have gone.

Dave cooling off in the hot tub

Fortunately we have the Hot tub set up in the garden still (It’s usually packed away by now) so I have been able to cool off in the water on the worst of the hot days.

Anyway, enough of the boring stuff. Let me get on and tell you about what I have done to the game this update.

The plan for this fortnight

After all the bugs I got fixed in the last update, here are only two bugs left in the known bugs/issues column on the Trello board.

  • Distance Issues
  • Stutter during gameplay

I am hoping to get both of these fixed and maybe even have time to start on the Phase 2 stuff.

Distance issues

I’m hoping this will be a simple bug to fix, so I have chosen this to be the first thing I look at.

The problem is that the Daily missions and the Trophies seem to check the distance travelled differently. For example, I completed a daily mission (Travel 25m), but the Trophy (Travel 25m) was not.

I need to look to see whether the code which compares the distances in the two cases is the same, or at least using the same calculation to work out distance.

Step one is to look and find where the two checks are made. This involves simply reading through the code and following its order of execution. Although its not a particularly fun or interesting thing to do.

I found the code which updated the daily mission distance variable in the IncreasePlayerScore() function. It is increased by 1 every time the player travels 144px (in game size), it’s the size of an old 4:3 TV episode on a widescreen device.

The other piece of the riddle was in the Trophies script. It was however calculating the distance in a completely different way.

Once I had found the issues, it was a fairly simple job to get both sets of code producing the same results.

Stutter during gameplay

Sadly I didn’t get this one finished this update. I managed to get as far as thinking about how I am going to determine what is causing it.

I haven’t even managed to grab any video of it happening. As I cannot replicate the issue on demand as yet. Intermittent problems are the worst kind.

I’m certain AGK Studio has some commands for performance checking. I will look into those and see if they might be helpful for this.

Phase 2

I did manage to get some thought put into Phase 2 however during some AFK time.

Phase 2 is mostly about adding longevity to the game play. I will be adding systems to increase the reward and difficulty of the daily missions; as well as looking into how we can adapt the levels depending on the speed of the player.

I’m leaning towards creating more levels and then give each level a speed rating, so the are not selected if the game is going to quickly or slowely. Then I just need to create several sets of levels so no variety is lost as the player speeds up.

Anyway, I shall talk more about phase 2 once the stuttering bug has been resolved.

That’s all for now

Once again I have run out of time, and the deadline for publishing this blog post draws near. So I shall sign off for now. I’ll be back in two weeks, with another fun packed and exciting* game progress update.

See you all next time!

* May not actually be fun packed or exciting
