Say you want to make it so that a free moving sprite cant move through a wall. How do I do this?

2

if <touching [sprite V]?>{ change y by (-1) }

3 
script variables ((old rot)) @>
set [old rot V] to (direction)
point towards [sprite V]
warp{
repeat until <([ray length V] to [sprite V]) > [0] >{
move (-1) steps //replace for non circle
}}
point in direction (old rot)
4

Shouldn't it be script variables?

Please elaborate...

5

replace the move steps for a non circle

6

Replace it with what?

7

depends

8

What's with the

warp{
repeat until <([ray length V] to [sprite V]) \> (0)> {
move (-1) steps
}
}

? Why not do move ((-1) - ([ray length V] to [sprite V])) steps

(Sorry, just noticed the date this was posted.)
