So I’m a little confused on the Circle collision provided by the Box2D.h library.
In it, I’m not sure where to find how big I can make it (by how large the radius is). Also, is the TestPoint function in b2CircleShape.h a function to test if a point is colliding with the Circle?
And is there any way to make the Circle stay in the position of an object that is moving around in relation to the object? For instance, I have a rectangular object that the top area will have the Circle shape. I want that to stay in that exact position with the object whenever the object is moved around. Do I have to constantly update the position of the object?
