Question by Martin Schultz · Jun 10, 2014 at 01:21 PM · rotationtransformrotatemathangle

Calc 30° left and x units forward from local forward axis

I have a GameObject (GO) named X and it is rotated somehow. Now, I want to calculate the position and orientation for another GO named Y, that shall be 30 units away and 30° left measured from the local Z forward axis. Can anyone help me on this?

Thanks!

You can get the position this way:

 var dir = Quaternion.AngleAxis(30, transform.up) * transform.forward;
 var pos = transform.position + dir * 30;

From your question, I don't understand the orientation. You might want:

 var rot = Quaternion.AngleAxis(30, transform.up) * transform.rotation;
