Quaternion.FromToRotation

参数

返回

Quaternion A unit quaternion which rotates from fromDirection to toDirection.

描述

Creates a rotation from fromDirection to toDirection.

Use this method to rotate a transform so that one of its axes, such as the y-axis, follows the target direction, toDirection, in world space.

using UnityEngine;

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