Apply force in local direction Software: Away3D 4.x

Oscar, Newbie Posted: 18 April 2012 07:46 AM Total Posts: 5 Hello! I’ve just started out with AwayPhysics and I’m stuck with a probably simple problem. I want to make a simple cylinder rigid body move with my arrow keys, preferably by applying forces in a correct way. I’m rotating the cylinder like so: `/When right key is held / _playerRotation += 3 _playerBody.rotation = new Vector3D(0, _playerRotation, 0);` I apply force to move my cylinder forward like: `/* When forward key is held */ _playerBody.applyCentralForce(new Vector3D(0, 0, 20));` The issue is that when the force is applied it simply moves in the Z-axis of the world, I want it to be pushed in the local rotation direction of the cylinder! How would I go about making this happen? Thanks!
