AddForce not working after position change?

Unity Engine
1

Hi, I’ve got some strange stuff happening with my rigidbody when I apply a force to it. I have the rigidbody getting set to a position with:

 object.transform.position = point.transform.position;

I then apply a force when a button is pressed with:

object.rigidbody.AddForce(point.forward *10000 + point.up *10000);

The problem is that as time goes on, the direction the force is applied in gradually changes until it goes directly down rather than up and forward. So if I fire straight away, then it works fine, but if I wait a few seconds it ends up going down. The Point is just a stationary point that doesnt move and I have debugged the forward and up vectors and they dont change, so I have no idea whats going on. The only thing that fixes it is not setting the position to the points position.

If it’s changing on you, you are probably using local positioning. I haven’t done much with this, but it’s where I usually get into trouble with things not doing what I want. I am thinking global, or world space, but my code directions are local, or object space.
