Works best when downloaded (very, VERY slow online).
This is a raycaster, ported over to Scratch. A raycaster allows for 3D scenes to be rendered from a 2D grid. Use the arrow keys to position the camera, then press space to render the scene.
The original code for this raycaster was written in BlitzBasic; I simply ported it to Scratch and optimized some things. It is still too slow for real-time calculations, but much faster than Canthiar's raytracer (because raycasting is much simpler than raytracing; raycasting in Scratch needs 480 calculations and draws, while raytracing needs 172800, assuming you're drawing pixel by pixel).

no, that's raytracing. Raytracing is much more advanced than raycasting, and can allow for much more detail.
