Let’s say tank shoots another tank, you get an angle and it’s 100°. Most likely the tank won’t penetrate the armor. How could I get angle from a raycast shot?
local ray = Ray.new(startVector, (endVector - startVector).unit * Configuration.FireRange.Value)
local hit, position, normal = workspace:FindPartOnRay(ray, Tank, false, true)
local distance = (position - startVector).magnitude
I don’t think getting the angle is possible (in an easy way)… I know it’s possible to get the side hit by normalId.
If your interested on working really hard to figure it out, I recommend associating surface normal vectors with degree angles on the X and Z axis’.
This is really easy, you just need to take the math.acos of the dot product of the two direction vectors, so that would be math.acos(ray.Direction:Dot(normal))
it keeps returning 
Oh right, you need to make sure the direction vectors have been normalized, so it should actually be math.acos(ray.Direction.Unit:Dot(normal.Unit))
The result will be in radians, so that looks ok to me.
how I convert it to degrees?
sorry If I sound dumb, but I never dealt with this stuff before.
Hey can you tell me what “normal” here is? How do I find it?
So this method is nearly 8 months old, and has actually been deprecated. You should be using the new raycasting function, in which you will receive an instance from a raycast. You would get the normal from the returned raycast result instance if the raycast returned anything.
