Raycast ignoring collision, need alternative method

[chanboiiiii (CHANB0II)]

I have a spinning target circle that’s supposed to represent where to aim. The only problem is that the raycast is ignoring collision, and I don’t know an alternative to raycasting.

The spinning circle is at the end of the beam. You can see it no-clipping through the blocks.

you’re setting the circle’s position to match the raycast result. raycasts are straight lines and the ‘position’ property only considers the object’s center. to keep the circle from passing through blocks, u should use spherecasting instead.
