I'm using a basic raycasting engine from this tutorial here —> https://www.youtube.com/watch?v=mzznRhUA1Tk

It's one of the most basic 3D raycasters you can make, but it is very buggy and laggy. I need a new alternative to use that doesn't cause so much lag. I also have been trying to find a tutorial on how to make raycaster entities, and I haven't had any luck. I'm working on chapter two of a 3D FPS, and all of the enemies are moving walls. I just need a bit of help and understanding of first person 3D since I'm new to it, so if you can help that would be great! Thank you!

Hi, i think the best way to reduce lag in this raycaster is to draw the wall without use list:

calculate distance
draw the line

If you want it to run fast, use Turbowarp. Code in Scratch, and playtest it in Turbowarp.

In the Scratch Wiki tutorial, there's some good suggestions to improve the speed: https://en.scratch-wiki.info/wiki/Raycaster

As for putting enemies in the maze that look like anything but moving walls, I have no idea.

Actually, some things can't be left with turbowarp… I tried my raycasting game on there, but it doesn't work any better.
