[quote="Magnemania"]Wouldn't the raycast be a bit faster if you calculated lengthdir_x and lengthdir_y outside of the for loop and saved it as a constant? It's generally best to use as few sin/cos operations as you can.[/quote]Oh, yeah, that's true. There's no reason to recalculate it every iteration. I edited the script now and placed it outside the loop - thanks for the heads-up.

Happy to help!
