Quaternion.FromToRotation 从from到to旋转

static function FromToRotation (fromDirection : Vector3, toDirection : Vector3) : Quaternion


Creates a rotation which rotates from fromDirection to toDirection.


Usually you use this to rotate a transform so that one of its axes eg. the y-axis - follows a target direction toDirection in world space.


using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
	public void Awake() {
		transform.rotation = Quaternion.FromToRotation(Vector3.up, transform.forward);
// Sets the rotation so that the transform's y-axis goes along the z-axis

transform.rotation = Quaternion.FromToRotation (Vector3.up, transform.forward);
