Godot is a multi-plaftorm game engine.
GitHub repository: https://github.com/godotengine/
The godot3 engine is being packaged.
Godot provides 3 binaries (and no libraries): the editor, the runner and the headless server.
The runner binary aka "export template" is close to an interpreter: it's called to run a .pck file that contains the game.
Godot integrates with other languages thanks to GDNative, which "bridges" between languages using a C API
The project can break compatibility on minor (but not patch) versions, hence packages are named godotX.Y godotX.Y-[runner|server]
Packaging Godot games
The source package for a game is built from the sources tar.gz as usual. Example for a game called "foo" that runs on godot3.1:
The binary contains the .pck file and a launch script e.g. /usr/games/foo and no server/runner, and it depends on godot3.1
The launch script contains:
/bin/sh /usr/bin/godot3.1 /usr/lib/godot3.1/foo.pck
