Cocos2d实现的Load。

通过加载资源的数目来控制Load百分比。

添加Bar，加载资源：

loadText = LabelTTF::create("Loading...", "Arial",20);loadPercent = LabelTTF::create("0%", "Arial", 20);addChild(loadText);addChild(loadPercent);Sprite *barback = Sprite::create(("loadingbar.png"));barback->setPosition(ccp(visibleSize.width*0.5, 300));addChild(barback);loadNum = 100;load = 0;progress = ProgressTimer::create(Sprite::create("sliderTrack2.png"));progress->setBarChangeRate(ccp(1, 0));progress->setType(kCCProgressTimerTypeBar);progress->setMidpoint(ccp(0, 0));progress->setPercentage(0.0f);progress->setPosition(ccp(visibleSize.width*0.5, 300));addChild(progress, 1);loadText->setPosition(ccp(visibleSize.width*0.4, 300));loadPercent->setPosition(ccp(visibleSize.width*0.5, 320));for (size_t i = 0; i < 100; i++){TextureCache::sharedTextureCache()->addImageAsync("HelloWorld.png", CC_CALLBACK_1(LoadScene::loadOver, this));}//schedule(schedule_selector(LoadScene::loadOver, 0.5f));

回调函数内容：

//void LoadScene::loadOver(float dt)void LoadScene::loadOver(Object *pSender){load++;char temp[10];float value = ((float)load / loadNum) * 100;sprintf(temp,"%d%%", (int)value);loadPercent->setString(temp);progress->setPercentage(value);if (load == loadNum){removeAllChildren();Scene *scene = changeScen::createScene();Director::getInstance()->replaceScene(CCTransitionPageTurn::create(3.0f, scene, true));}}
