How does raycasting work?

I don't remember perfectly what that griffpatch tutorial said exactly but it's basically sending rays across a top-down maze. Each ray then represents one line that is drawn in the 3d world, the distance it is from the player draws a shorter line.

Now I need help with getting items in between a list now I need to get items 1 to 5 in a list( I’m gonna put my variable It which is iteration in it)

I don't think you need a variable for this, there's many other ways that take up less space that let you take the first 5 items of a list.
