1.LeanTween.reset()

一、工具介绍

参考：推荐开源项目：LeanTween - 为Unity 3D打造的高效缓动引擎-CSDN博客

LeanTween是一个专为Unity 3D引擎设计的高效缓动（tweening）库，它提供了简单易用的API，帮助开发者轻松实现各种复杂场景。

二、常用的方法详解

---

1.LeanTween.reset()

 很明了的方法，用于重置，最好在每次加载的时候进行重置，一般放在Start或者Awaik方法中使用

---

2.LeanTween.addListener和LeanTween.dispatchEvent

 

代码示例：

public class MoveTools : MonoBehaviour
{public GameObject ball;public MyActions action;void Start(){LeanTween.reset();LeanTween.addListener(this.gameObject, (int)MyActions.Jump, jumpUp);}void Update(){if (Input.GetKeyDown(KeyCode.Space)){Debug.Log("jump!");LeanTween.dispatchEvent((int)MyActions.Jump, this);}}void jumpUp(LTEvent e) { Debug.Log("LTEvent:" + e.ToString()); }}public enum MyActions
{Idle,Jump,
}

---

3.LeanTween.moveSpline

让物体按照一些列点进行移动，但是需要注意的是，第一个点和最后一个点不会经过

public class TestMoveSpline : MonoBehaviour
{public MyActions action;public List<GameObject> targets;private Vector3[] positions; //void Start(){positions = new Vector3[targets.Count];LeanTween.reset();for (int i = 0; i < targets.Count; i++){positions[i] = targets[i].transform.position;}}void Update(){if (Input.GetKeyDown(KeyCode.Space)){LeanTween.moveSpline(gameObject, positions, 3.0f);}}}

---

4.LeanTween.rotate系列

rotate系列有：

• rotate(GameObject gameObject, Vector3 to, float time)
• rotate(LTRect ltRect, float to, float time)

• rotateLocal(GameObject gameObject, Vector3 to, float time)

• rotateX(GameObject gameObject, float to, float time)

• rotateY(GameObject gameObject, float to, float time)

• rotateZ(GameObject gameObject, float to, float time)

• rotateAround(GameObject gameObject, Vector3 axis, float add, float time)

• rotateAroundLocal(GameObject gameObject, Vector3 axis, float add, float time)

优点：直接输入需要旋转的角度，用法也简单，妈妈再也不用担心旋转的时候发万象锁啦~

需要注意的是：rotate旋转方向以180°为界，会寻找离当前位置最近的角度进行旋转。

如果要旋转超过180°的话，需要用rotateAround方法，例如要不停的旋转360°，写法可以是：

LeanTween.rotateAround(gameObject, transform.up, -360f, 5f).setLoopClamp();
