一、解析
1）包含4个动作
1.CCFiniteTimeAction 和时间相关的动作
2.CCFlow 让图层跟随精灵移动
3.CCReapeatForever 循环
4.CCSpeed 和速度相关的动作
//————————-
2）CCFlow 让图层跟随精灵移动
3）CCFiniteTimeAction 分
a.CCInstantAction 瞬时动作 闪现
b.CCIntervalAction 延时动作 奔跑
二、jumpBy , moveTo , moveBy
1) moveBy 有 reverse() 而moveTo没有
2) jumpBy height指的是跳跃时抛物线最高点离物体的距离
CCJumpBy.action(time,pos ,height, jumps);
三、复杂动作
1）ccSpawn //两个动作并行运动
2) CCSequeue //两个动作串联运动
3) CCRepeatForever //无限循环运动
四、代码实现

private CCSprite mManSprite;

init();
}

moveTo();

scaleBy();
rotateTo();
rotateBy();
bezierBy();// 曲线
fadeIn();
ease();// 加速度
colorChange();
blink();//闪烁
multiAction();//综合动作
}
