Daedalus is an open source engine specialized toward mazes. It allows creating, solving, displaying, and analyzing mazes of many types and algorithms. It features a scripting language that can access and drive all its features and settings. Therefore "Daedalus" refers to both the program itself and the Daedalus programming language it implements. Daedalus is architected around bitmaps. Daedalus has a simple ray casting rendering mode that's defined by a list of bitmaps: Where blocks are placed is stored in one bitmap, the color of each block is in another, the height of each block is in a third, textures to display on the sides of blocks are in other bitmaps, etc. The Daedalus scripting language uses macros and events. Events call macros and are fired by the program when things happen, such as when the mouse is moved or clicked, or when you move the viewing point (e.g. your character) from one location to another. Daedalus scripts are plain text, and easily modified in text editors.
