Checking slope angle the object is standing on?
How can I get the angle of the slope an object is standing on?
Thanks

The angle can be computed from the collision normal (assuming you have it available). For example, if +y is up, the angle can be computed as follows (untested):
float angleInRadians = Mathf.Acos(Mathf.Clamp(normal.y, -1f, 1f));
Sorry, this is probably a really dumb question. What does the normal variable contain?
A normal is a vector that is at a right (90 degrees) angle from the plane.

All the blue arrows are normals for the point they're co$$anonymous$$g from (immagine each point is part of an invisible STRAIGHT plane). So if you have an "up" direction for the slope (the collision normal), you can calculate the angle.
