大体思想：

动画效果的使用：

根据图片创建纹理--》根据纹理创建帧，将帧放入到类似List的对象中anim，将

Cpp代码

1. CCAnimation *animation=CCAnimation::animationWithFrames(anim,0.04f);  
2. CCAnimate *animate = CCAnimate::actionWithAnimation(animation,false); 

[cpp] view plaincopyprint?

1. CCAnimation *animation=CCAnimation::animationWithFrames(anim,0.04f); 
2. CCAnimate *animate = CCAnimate::actionWithAnimation(animation, false); 

CCAnimation *animation=CCAnimation::animationWithFrames(anim,0.04f);CCAnimate *animate = CCAnimate::actionWithAnimation(animation, false);

 

用第一帧创建CCSprite，

最后精灵runAction

如果要执行多个动画，可以runAction(CCSequence::actions(...));

先将图片异步加载到缓存，异步加载看cocos2d-x源码就是多线程加载，用的pthread，以后使用图片就会更快，这一步一般都是游戏开始的时候用进度条来显示

Cpp代码

1. CCTextureCache::sharedTextureCache()->addImageAsync(garden_petal1,this,callfuncO_selector(Garden::loadingCallBack));  
2.     //CCTexture2D *texture1=CCTextureCache::sharedTextureCache()->addImage(garden_petal1); 
3.     CCTextureCache::sharedTextureCache()->addImageAsync(garden_petal2,this,callfuncO_selector(Garden::loadingCallBack)); 

[cpp] view plaincopyprint?

1. CCTextureCache::sharedTextureCache()->addImageAsync(garden_petal1,this,callfuncO_selector(Garden::loadingCallBack)); 
2.     //CCTexture2D *texture1=CCTextureCache::sharedTextureCache()->addImage(garden_petal1); 
3.     CCTextureCache::sharedTextureCache()->addImageAsync(garden_petal2,this,callfuncO_selector(Garden::loadingCallBack)); 

CCTextureCache::sharedTextureCache()->addImageAsync(garden_petal1,this,callfuncO_selector(Garden::loadingCallBack));//CCTexture2D *texture1=CCTextureCache::sharedTextureCache()->addImage(garden_petal1);CCTextureCache::sharedTextureCache()->addImageAsync(garden_petal2,this,callfuncO_selector(Garden::loadingCallBack));

在回调函数中处理进度条的显示
