A template to build Windows/macOS/Linux binaries with Github Actions

[mrhelmut]

I needed to make a dummy game for all systems and it turned out that the result is likely a worthy example of how to use MonoGame, NativeAOT, and Github to automatically build games in a Steam-ready format. So here goes the code: https://github.com/FlyingOakGames/PlaceholderGame

What this template does:

• it builds the game for Windows, macOS, and Linux natively
• it packages the game for release to be compatible with stores such as Steam
• it notably creates a macOS .app bundle that supports both x64 and arm64 natively
• Github Actions will build the game for all systems and all there is to do is grabbing the .zip and uploading to stores

This is a similar setup that we use inhouse to build and ship games. You can also leverage Github Actions to publish directly to Steam using this action.
