cocos2d-x中的动画的使用

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);  

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));  

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
