I’ve just finished writing up version 0.04 of my fairly buggy raycaster demonstration, which you can find at bitrevision.com/mike/raycaster. The source code is also available from there. This one will only work on Windows.
The controls in this version are:
- Movement: Up, Down, Left, Right arrows.
- Return to start: Enter (return).
- Debug mode: Space bar.
The rendering bugs in this version will be fixed by a partial re-write for the 0.05 release.
