Fun with Ray Casting

[a740g]

It all started with this post.

This is an implementation of the Voxel Space ray casting in QB64-PE. The algorithm is explained here.

You'll need QB64-PE v4 to compile and tinker. This is just a demo, not a complete game. At best, it can be called a walking simulator.

The demo is configured to best perform for my Ryzen 5600x system. If you see low FPS, tweak the RENDER_DISTANCE and RENDER_DELTA_Z_INCREMENT constants at the top of the source code.

Code: (Select All)

CONTROLS:

KEYBOARD:
   FORWARD:        W / UP
   BACK:           S / DOWN
   STRAFE LEFT:    A
   STRAFE RIGHT:   D
   TURN LEFT:      LEFT
   TURN RIGHT:     RIGHT
   NEXT MAP:       SPACE

MOUSE: MOUSE LOOK

Mouselook may be broken on Linux because of how _MOUSEMOVEMENTX/Y is implemented in QB64. We'll fix this soon™.

Have fun. Cheers!

Adding my original solid-wall RayCaster here for completeness. I'll keep posting other ray-casting-related stuff in this thread in the future.

I didn't know that making a type variable as a type was even possible :o
