JavaScript => public static function RotateTowards(from: Quaternion, to: Quaternion, maxDegreesDelta: float): Quaternion;
C# => public static Quaternion RotateTowards(Quaternion from, Quaternion to, float maxDegreesDelta);

Parameters 参数

Description 描述

Rotates a rotation from towards to.

旋转一个角度从from向to。

The from quaternion is rotated towards to by an angular step of maxDegreesDelta (but note that the rotation will not overshoot). Negative values of maxDegreesDelta will move away from to until the rotation is exactly the opposite direction.

四元数表格是旋转朝向maxDegreesDelta的角度(但是注意旋转不会越过目标)。maxDegreesDelta的负值将会远离直到旋转到相反的方向。

JavaScript:

		// The object whose rotation we want to match.
	var target: Transform;
 
	// Angular speed in degrees per sec.
	var speed: float;
 
	function 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);
	}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    public Transform target;
    public float speed;
    void Update() {
        float step = speed * Time.deltaTime;
        transform.rotation = Quaternion.RotateTowards(transform.rotation, target.rotation, step);
    }
}
