cocos2dx中的三种缓存

TextureCache纹理缓存
使用纹理缓存可以创建纹理对象

auto cache = Director::getInstance()->getTextureCache()->addImage("bg.png");
auto sprite = Sprite::createWithTexture(cache);

SpriteFrameCache精灵帧缓存

SpriteFrameCache::getInstance()->addSpriteFramesWithFile("main.plist");
auto sprite = Sprite::createWithSpriteFrameName("bg.png");

AnimationCache帧动画缓存

auto running_animation = Animation::create();
AnimationCache::getInstance()->addAnimation(running_animation,"running");
auto run = AnimationCache::getInstance()->animationByName("running");
