Title: Rotate slowly to target?
Post by: GameDragon on November 09, 2013, 02:48:54 am

I've searched and used this code to rotate my object to a target:

Code: [Select]

Vector3 direction = targetPoint - transform.position;
transform.eulerAngles = new Vector3(0, 0, Mathf.Atan2(direction.y, direction.x) * Mathf.Rad2Deg);
But I'd like to add some rotation speed to this to make it rotate more slowly. How would I go about doing this?

Mathf.Atan2(direction.y, direction.x) * Mathf.Rad2Deg gives you the angle - what you could to is start from the current transform.eulerAngles.z and then slowly move towards this instead of setting it directly.

I've tried:

Code: [Select]

Vector3 direction = player.transform.position - transform.position;
direction = new Vector3(0, 0, Mathf.Atan2(direction.y, direction.x) * Mathf.Rad2Deg);
transform.eulerAngles = Vector3.Lerp(transform.eulerAngles, direction, speed * Time.deltaTime);
But all that does it make it spin out uncontrollably.

Use Math.MoveTowardsAngle to move move the rotation value from the previous value to current. You don't need to lerp all of eulerAngles, just use MoveTowardsAngle on the z value. Check the unity docs for more details.

That makes so much more sense. Thank you very much.
