odin-raylib-web-pong

An implementation of Pong written in Odin using Raylib. Running natively on desktop and compiled to WASM to run in the browser.

Based on the odin-raylib-web project template by Karl Zylinski.

This project was meant to try out the feasability of making a graphical application for the web using WASM with minimal setup. It also tests how usable Odin and Raylib are for a simple game.

Local setup

Requirements

Odin compiler from January 1st 2025 or newer
- https://odin-lang.org/docs/install/#official-releases
- On Windows: Requires MSVC and Windows SDK
(For web builds) Emscripten SDK
- https://emscripten.org/docs/getting_started/downloads.html#installation-instructions-using-the-emsdk-recommended
- Also EMSCRIPTEN_SDK_DIR in build.bat
(On Windows) Git Bash
- build.bat uses Git-Bash by default on Windows to itself under Bash
- Git-Bash ships with Git so you should already have it, otherwise install Git
- If you wish to use another Windows Bash, edit the line set WIN_BASH= in build.bat

Desktop builds

For debug builds run build.bat debug
For release builds run build.bat web

Web build

Point EMSCRIPTEN_SDK_DIR in build.bat to where you installed emscripten.
Run build.bat web.
Web game is in the build/web folder.

Note

On Linux and macOS, build.bat must be invoked as bash build.bat.

Warning

You might not be able to run build/web/index.html directly due to "CORS policy" javascript errors. You can work around that by running a small server, i.e.:

npx http-server ./build/web -c-1
python -m http.server --directory ./build/web
