WadC

WadC is a programming language designed for constructing Doom levels. It was written by Wouter "Aardappel" van Ootmerssen.

The system takes the form of a two pane window. In the left pane, WadC code can be written. A preview of the resulting level is displayed in the right pane.

WadC has advantages over traditional level editors in that it is easy to form repeating structures: a function can be written to create a pillar, for example, and invoked to create many pillars.
