How to find out if there is a point (unit) in an object?

Question

C++ / C#

Let's say I want to spawn an object, let's say a cube at a point x,y,z, how can I determine if there are other objects at this point. There is some kind of MB function.

Answer 1

I think it's not a collider, but a cast. To check if the cube will interfere with someone here:
