cocos2d-x 血量条 CCProgressTimer实现

直接上代码

//背景图片，

        auto* hpBgSprite = Sprite::create("hpbg.png");

hpBgSprite->setPosition(Point(visibleSize.width/2, visibleSize.height/2-100 ));
       this->addChild(hpBgSprite);

   

//有血量的图片

auto hpBar = CCProgressTimer::create(Sprite::create("hp.png"));
hpBar->setType(ProgressTimer::Type::BAR);
hpBar->setMidpoint(Point(0, 0.5f));
hpBar->setBarChangeRate(Point(1, 0));
hpBar->setPercentage(50);//血量
hpBar->setPosition(Point(0,0));//坐标点，相对于背景的
hpBar->setAnchorPoint(Point(0,0));//锚点
       hpBgSprite->addChild(hpBar);
