Quaternion.RotateTowards

参数

返回

Quaternion A unit quaternion rotated towards to by an angular step of maxDegreesDelta.

描述

将旋转 from 向 to 旋转。

The from quaternion is rotated towards to by an angular step of maxDegreesDelta. The rotation will not overshoot the to quaternion. Negative values of maxDegreesDelta moves away from to until the rotation is exactly the opposite direction.

using UnityEngine;

public class Example : MonoBehaviour
{
    // The object whose rotation we want to match.
    public Transform target;

    // Angular speed in degrees per sec.
    public float speed = 1.0f;

    void Update()
    {
        // The step size is equal to speed times frame time.
        var step = speed * Time.deltaTime;

        // Rotate our transform a step closer to the target's.
        transform.rotation = Quaternion.RotateTowards(transform.rotation, target.rotation, step);
    }
}
