i want bullets to be deflected when they hit a slopped surface
something like this

To detect if a bullet hits a slope, or any BasePart in general, you should try raycasting. And if you are wanting to make the bullet be deflected, try using the Normal of the raycast to calculate where it should be deflected.

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…

Here’s a small demo I created to show how it works and how it would look like. You can use this as a starting point if you don’t have one already.
