Hi,
I’ve recently made a 3D raycaster (link) Snap! Build Your Own Blocks
but it is extremely laggy! How do I reduce the lag?
You're not using the distance variable, and your step size is too small.

There is actually a reporter for getting the ray length to a sprite
This is much faster because you don't need to move steps.
