I've read some tutorials on how to implement a raycaster and just implemented one in Rust for the Firefly Zero retro game xonsole.
It's still way too slow to run on the actual device, but I'm planning on trying out other implementations that are hopefully less resource intensive.
I've now implemented the DDA algorithm to calculate wall height, which makes the code much faster. It also fixed the slightly bent walls with the last implementaton.
Though now the map seems to be mirrored, and I haven't made it work properly when switching between rendering modes.
Next up is adding back textures.
The wall textures in my ray caster are back. This time with a slight shadow on two sides of the walls.
It's only about twice the speed compared to the old implementation that only used textured walls. Which means a lot of the work is in drawing the textures.
Now I've added back floor and ceiling rendering using a horizontal algorithm. This is about twice as fast as the old rendering method. Most of the time is spent drawing pixels.
The raycaster now has support for stationary sprites. Next up is probably adding support for sprite scaling and changing height position.
