Questions tagged [gml]

Game Maker Language (GML) is an interpreted scripting language developed for use with a computer game creation application called Game Maker. Use this tag only for questions about language features, or requiring code in Game Maker Language.

Game Maker Language (often called GML) is an interpreted scripting language developed for use with a computer game creation application called Game Maker. It was originally created by Mark Overmars to supplement the drag-and-drop action system used in Game Maker. However, in the latest versions, all the drag-and-drop actions translate to GML rather than being separate from it.

The scripting language lacks some of the features of its parent language JavaScript, as well as of other object oriented programming features. The language also lacks proper data types and overloading.
