Question by dakstab · Dec 31, 2013 at 06:16 PM · relative rotationlocal axis

AddRelativeForce not working for x axis rotation?

When I rotate my object around the y axis, and use rigidbody.AddRelativeForce(Vector3.forward); it moves forward based on where I'm facing, but when I rotate my object along the x axis and use rigidbody.AddRelativeForce(Vector3.up 400); no matter where I'm facing, even if my object is upside down, it will always move my object up on the y axis. I thought AddRelativeForce would move it down on the y axis if my object was upside down, but no matter where I'm facing, no matter how I'm rotated along the x axis, it will move my object up on the y axis with the same force. I have already checked many posts on the forums for help, but the problem has always been that they used AddForce, and the solution was always to use AddRelativeForce.
Here is a picture of it normally http://prntscr.com/2fg6qv, and I can walk facing right or left, and AddRelativeForce(Vector3.forward) works perfectly, but when I do this http://prntscr.com/2fg773, face upward and use AddRelativeForce(Vector3.up
400), I would expect it to push me backwards, but instead, it pushes me upwards, relative to the global position.

I've also tried AddRelativeForce(transform.up 400); and I've tried AddForce(transform.up 400), nothing is working based on the object's local y axis. If I changed that code to AddForce(transform.forward), then it would work based on the object's local x and z axis, so why won't it do the same for the local y axis?

I've even tried using transform.Translate (Vector3.up 100 Time.deltaTime);, transform.localPosition += Vector3.up;, transform.localPosition += new Vector3( 0, 2, 0);, and transform.position += new Vector3( 0, 2, 0);, but nothing seems to work, they all just move my object up on the global y axis, no matter how my object is rotated.
