How do I make LookRotation use X instead of Z?

Questions & Answers

I have a snippet of code:

Quaternion _rot = Quaternion.LookRotation(new Vector3(_waypoints[_waypoint].x, _waypoints[_waypoint].y, 0) - _transform.position, _transform.up);
_transform.rotation = Quaternion.Slerp(_transform.rotation, _rot, (Time.deltaTime*1.5f));

The vector full of waypoints changes to the next one every time the character meets a waypoint. The character is moving in X and y, not in X. This script is meant to rotate a GameObject over time to have it’s transform.forward (z) facing the next Waypoint (Vector3, without a Z coordinate)

My question is, what do I need to do in order to make the GameObject’s transform.right (x) face the next waypoint, instead of its transform,forward(z).

You can combine the LookRotation with an appropriate fixed rotation. It’s equivalent to add the fixed rotation to LookRotation:

Quaternion _rot = Quaternion.LookRotation(...);
_rot *= Quaternion.FromToRotation(Vector3.forward, Vector3.right);
_transform.rotation = Quaternion.Slerp(_transform.rotation, _rot, (Time.deltaTime*1.5f));
