I just wanted to write simple tutorial how to compile the best open-source game engine, Godot. This will get you the latest unstable tool with possibly many bugs. That sad it works flawlessly most of the time.
Libs:
$ sudo swupd bundle-add os-utils-gui-dev
$ sudo swupd bundle-add hardware-gpu
Clone the project and compile:
$ git clone https://github.com/godotengine/godot.git
$ cd godot
$ scons p=x11 -j<THREADS> (this will take some time...)
$ sudo cp bin/godot.x11.tools.64 /usr/bin/godot
Change to number, eg -j4 for four threads (do not use space).
Run godot
anywhere for editor or inside game project to just run that game.
For stable version just use flatpak:
flatpak install flathub org.godotengine.Godot
Now go and make a game!
