This project was created as a challenge to learn how to make the functionalities of a game engine (starting with a rendering engine) but also to further experiment with ODIN and to learn how to work with WGPU for cross-platform game development from scratch.

The project may progress with some poorly positioned code as I learn and improve.

Below are some features I hope to impleent over time if I continue with the project and don't find something else to fill my spare time. I will continnue to add to the list as I think of new things that would be interesting to work on.

Web build: (I currently use python's test web server)

• build_web.bat on windows. I will add a linux shell script at some point also.
• python -m http.server -d web
• open browser to localhost:8000

Windows build needs the SDL2.dll file in the build output directory. I have created a script prepare_build.bat which can create the output directory and copy the required files over. VSCode is configured to run this as a pre-build step but it can be run manually using prepare_build.bat debug or prepare_build.bat release

Odin does not have some of the default libraries required to run this sample installed by default. Here are the steps I used to get the test running on Linux Mint.

Download https://github.com/gfx-rs/wgpu-native/releases/tag/v24.0.0.2 These are expected in Odin's lib folder under the same name as they are released (just unzipped).

make -C "~/Tools/Odin/vendor/stb/src"
make -C "~/Tools/Odin/vendor/cgltf/src"

sudo apt-get install libsdl2-dev
odin run .

The ability to use VSCode for build/debug has also been included by selecting the "(Linux Debug) Launch" launch configuration
