Calculate angle from current heading to target object

October 16, 2011 – 22:58

If you want to have an object turn automatically towards a target then you have to find out in which direction to turn. The usual angle function just returns the smallest angle between the current heading and the heading towards the target but not which way around. Vector3 lTarget = transform.InverseTransformPoint(target.position); targetDistance = lTarget.magnitude; targetAngle [...]

Get Vector3 from Quaternion / Rotate Vector3

September 13, 2011 – 10:39

To get the vector from a quaternion rotation you simply multiply the quaternion by the forward vector. Debug.DrawRay(transform.position, transform.rotation * Vector3.forward, Color.red); This also effectively rotates the forward-vector with the rotation of the transform, positioning it relative to the rotation of the actual object.
