How would I make a bouncing part?

Hey there,

How would I get the direction, Orientation or CFrame doesn’t matter, of where a part or laser would bounce off of. Here’s a picture to better explain.

If I have a part which is at one point and is facing a wall, how would it turn to look like it’s opposite. Facing straight into the wall would be straight back, but a right angle turn would be at an offset. I do not know how to calculate this. I tried using dot product but I don’t know how to effectively use it yet.

I want to know how to get the direction after it touches the block.

How to reflect rays on hit

Reflecting rays using raycasting Want bullets to ricochet? Lasers to bounce? Custom Pong game? Here’s a simple way to reflect a ray when it hits a surface using the surface normal returned by the Raycast method! Formula We will be working with this equation: r = d - 2(d ⋅ n)n Where r is the resultant reflection normal, d is the normal of our ray, and n is the surface normal that our ray hit (We will get n from the RaycastResult that the Raycast method returns). Because we are doing reflec…
