CCProgressTimer进度条效果

收集整理的两个进度条效果,第一个常用于技能冷却，第二个用于加载进度或血量之类

bool HelloWorld::init()
{
    if ( !CCLayer::init() )
    {
        return false;
    }
    
	CCSprite *s2=CCSprite::create("pa2.png");
	s2->setPosition(ccp(200,200));
	addChild(s2,0);

	CCSprite *s=CCSprite::create("pa1.png");
	CCProgressTimer *pt=CCProgressTimer::create(s);
	pt->setPosition(ccp(200,200));
	//转圈的CD实现
	pt->setType(cocos2d::CCProgressTimerType(kCCProgressTimerTypeRadial));
	//从中间到外的出现
	this->addChild(pt,1);
	CCProgressTo *t=CCProgressTo::create(8,100);
	pt->runAction(CCRepeatForever::create(t));

	CCSize size = CCDirector::sharedDirector()->getVisibleSize();
	CCPoint origin = CCDirector::sharedDirector()->getVisibleOrigin();
	// 设置进度条的背景图片 我们把他放到屏幕下方的1/5处	
	CCSprite* loadbackimg=CCSprite::create("lodingbg.png");

	loadbackimg->setPosition(ccp(size.width/2 + origin.x,size.height/5 + origin.y));
	this->addChild(loadbackimg,1);

	// 添加进度条
	CCSprite* loadimg=CCSprite::create("longding.png");
	
	CCProgressTimer* pt2 = CCProgressTimer::create(loadimg);
	pt2->setType(kCCProgressTimerTypeBar);// 设置成横向的
	//可以看作是按矩形显示效果的进度条类型
	pt2->setMidpoint(ccp(0,1));   // 设置进度方向
	pt2->setBarChangeRate(ccp(0,1));  // 设置进度为水平还是垂直方向
	//重新设置锚点
	pt2->setPosition(ccp(size.width/2 + origin.x,size.height/5 + origin.y-5));
	pt2->setPercentage(10);
	this->addChild(pt2,2,1);

	//为该层设置定时器  
	this->scheduleUpdate();  
    return true;
}

void HelloWorld::update(float dt)  
{  
	// 刷新进度
	CCProgressTimer* pt=(CCProgressTimer*)this->getChildByTag(1);
	float now=pt->getPercentage();
	if(now == 100){
		now = 0;
	}
	pt->setPercentage(now + 1);
}
