求助 cocos2d-x 遇到一个奇怪的问题

[woof_1128]

自己定义的一个精灵类在游戏界面实例化了三个对象最后分别调用每个对象的schedule方法来是精灵运动问题是只有最后一个对象的可以运动起来 自定义类.h文件

#ifndef __Test__CustomSprite__
#define __Test__CustomSprite__

页面调用

cs=CustomSprite::create("fpai.png","fpai.png");
cssecond=CustomSprite::create("fpai.png","fpai.png");
csthird=CustomSprite::create("fpai.png","fpai.png");

cs->Excutefun();
cssecond->Excutefun();
csthird->Excutefun();

高手帮帮忙看看是什么问题那？在线等，急急急！！！！
