DECORATE is a scripting and content definition language in ZDoom that is used to create new actors. The origin of the name stems from its initial use merely as a way to create new decorations without having to steal frames from other actors, as required by DeHackEd. Starting with ZDoom v.2.3.0, all actors from all games have been removed from the executable and exported to the DECORATE lump in zdoom.pk3. Their code can be browsed on the ZDoom wiki for reference, offering a large quantity of examples to someone wishing to learn the language.
