How can I increase and decrease the radius of Unity’s primitive sphere to my likings? I have to change the actual sphere, not the collider itself. I have searched google for this but they all are changing the actual collider, not the mesh. Thanks!!
Just change the localScale of the transform.
var go = GameObject.CreatePrimitive(PrimitiveType.Sphere);
go.transform.localScale = Vector3(scale, scale, scale);
…where ‘scale’ is a variable or some constant.
Your question asks about changing the actual mesh. Is there some reason that you need to mesh rather than scaling the transform? If so does it have to be done at runtime?
