Quick explanation: I am trying to design a system where I get a random point from a circle and I managed to create the random point and I spawn a mesh cube for me to visually see it working, but the issue I am having is that when I decide to rotate off the forward axis (-z) the point does not rotate, I have attempted to rotate it like so.
rand_point = rand_point.rotated(Vector3.RIGHT,player.rotation.y)
unfortunately this does not work, im not good at dealing with rotations.
