Launch maps from Hammer

Let's assume you want to launch a map you made, just like in the Source Engine. Create a scene (scenes/map.tscn for example) with the root type VMFRuntimeController and do some additional setup in Hammer:

1. Open Tools -> Options -> Build programs tab. In Game Executable, specify the path to the Godot Engine executable.

For example: $SteamUserDir\Godot Engine\Godot_v4.4.1-stable_win64.exe

2. Open Run Map window (F9).
   • Click "Edit" and add a new configuration.
   • Select the created configuration in Configurations field
   • Click "New" and add $game_exe into the Command field.
   • Add --path $gamedir scenes/map.tscn --vmf $file into the Parameters field.
