基于LeanTween的封装

灵感来自于cocos2d-x的动画类。

完整代码：

using UnityEngine;
using System.Collections;
using System;

//动画基类
abstract public class WQPAnimation
{
	public WQPAnimation()
	{
	}
	public void play()
	{

	{

	}

	}

//顺序

}

LeanTween的下载可以网上搜索，这里我给一个我上面用的。

例子：

//0.5秒渐现-显示1.5秒-消失0.5秒-间隔0.5秒-0.5秒渐现-显示1.5秒-消失0.5秒-间隔9.5秒
	void AnimBegin()
	{
		WQPASequence sequ = new WQPASequence ();
		WQPValue value1 = new WQPValue (gameObject, ObjValue, 0f, 1f, 0.5f);
		WQPADelay del1 = new WQPADelay (gameObject, 1.5f);
		WQPValue value2 = new WQPValue (gameObject, ObjValue, 1f, 0f, 0.5f);
		WQPADelay del2 = new WQPADelay (gameObject, 0.5f);
		WQPValue value3 = new WQPValue (gameObject, ObjValue, 0f, 1f, 0.5f);
		WQPADelay del3 = new WQPADelay (gameObject, 1.5f);
		WQPValue value4 = new WQPValue (gameObject, ObjValue, 1f, 0f, 0.5f);
		WQPADelay del4 = new WQPADelay (gameObject, 9.5f);
		sequ.addAnim (value1);
		sequ.addAnim (del1);
		sequ.addAnim (value2);
		sequ.addAnim (del2);
		sequ.addAnim (value3);
		sequ.addAnim (del3);
		sequ.addAnim (value4);
		sequ.addAnim (del4);
		WQPARepeat rep = new WQPARepeat (sequ, -1);
		rep.play ();
	}

是不是很方便。。。
