Chaze in the Maze (Freebasic Demo)

Chaze in the Maze (Or... Digital Tag)

A FreeBASIC demo where you control a white asterisk, the Computer controls a little red face, and both of you are placed in a maze. Oh, and the Computer chases you 😃

Features

• No square roots; only Integers used, no divisions
• No queues & no stacks used!
• Wall following
• Main trick is Walter D. Pullen's Chain Algorithm, from his Daedalus program (see the Algorithms page, and the Daedalus page)
• Cross product of Vectors! 😱 (Idea taken from StackOverflow)
• A touch of Bresenham's Line Algorithm (adapted and simplified from the pseudocode at the Wikipedia page)
• Compile in Debug Mode and see the Chain Algorithm in action

Requirements

• The FreeBASIC compiler, basically 😁
• If you use Windows and just want to try the demo, go to the Releases section and download the compiled program

Post-mortem notes

If I see even a tiny bit of interest in this project I'll add some production notes regarding this little program of mine (on which I spent two months and a half, in the spare time).

For now, I'll say that English is not my first language, I tried my best to add meaningful comments to the source 🙂
Also, most of the maps included were converted or produced with the Daedalus program. Slot Racers and Miniature Golf are two old Atari 2600 games.
