FGDs

This is a FGD (Forge Game Data) file used to define all of the entities of a game for a map editor (such as Hammer).
To add a FGD file to the map editor, copy the following text into a text editor such as Windows Notepad, Notepad++ or Visual Studio Code, and save it with "save as type" being "all files" and .fgd appended to the file name. Then open your map editor and add the FGD to your game configuration (Example for HL:S).

Tip:Select the beginning of the line (usually the "//" comment) by clicking it, scroll down then hold ⇧ Shift, and click at the end of the line to select all.
