essentially what I mean ia a rollercoaster- we have a rigidbody that can only move along forward or backward on the rollercoaster geometry. In physical terms, of all forces applied to the rigidbody only the component along the rollercoaster geometry are considered while the remaining directions are confined by the geometry. Is there a simple way to implement this?
In the end I would like to take a box and have a sphere slide along one of its principal axes, still computed by the physics engine.
I’m sorry I don’t know of anyway to do this, you could apply an animation to it, then just adjust the animation’s speed. Other than that I don’t know if that’s possible
