2etime Game Engine

Hello, world! Welcome to the 2etime Game Engine Repository. Here you will find all of the source code from my past tutorials on youtube. https://www.youtube.com/2etime

Getting Started

In order to run the code, all you really need is x-code. Simply find the project you want to run and double click the .xcodeproj file. This will open up the entire project, where you can view, edit, and hell even optimize the engine.

I have listed all of the project files from each episode of the tutorial at the bottom of this readme.

Folder Structure

BuildAlong:
- Random Code Projects I do with the tutorials via streaming.
Community:
- For you to add cool projects to and share with others.
Full Current Project:
- The latest episodes code. Should be up to date with the last episode I did on the series.
Helpful Files:
- Files I have done in the series (keynotes, cheatsheets, etc)
Playcode:
- A place for me to put random work I am doing for you to learn with.

Contributing

Since this is an ongoing tutorial series, it wouldn't really make sense for you to contribute to the episode files.

However, if you use the engine to build out something badass... Feel free to add that to the Community folder, and submit a Pull Request. If it is something really cool, I may even feature it in one of my tutorials :)

Minor Suggestion for MetalTypes

While going over your code to figure out a better design for my ToyEngine for learning Swift/Metal. I was looking over your sizeable protocol (a solid idea), and noticed that I had a usecase where I wanted to apply it to Int as well. It took a little wrangling, but sorted out how it could be accomplished and extended for any Scalar.

I didn't make this a PR as you had mentioned you weren't too keen on them in one of your videos, but wanted to share this in case you found a need for different Scalar in the future.

What exists today:

public typealias float2 = SIMD2<Float>
public typealias float3 = SIMD3<Float>
public typealias float4 = SIMD4<Float>
...
extension float2: sizeable { }
extension float3: sizeable { }
extension float4: sizeable { }

With some generic magic you could cover all types beyond just Float:

private typealias simd2<T>  = SIMD2<T> where T: SIMDScalar
private typealias simd3<T>  = SIMD3<T> where T: SIMDScalar
private typealias simd4<T>  = SIMD4<T> where T: SIMDScalar
...
extension simd2: sizeable { }
extension simd3: sizeable { }
extension simd4: sizeable { }

From there I'm just using the other aliases that are already provided already:

print(simd_float3.size)
print(simd_int2.stride)

Thanks for making some great videos!
