CCProgressTimer 不循环

我想问一下，我在网上找的代码都是带循环的

shootingTime = CCProgressTimer::create(CCSprite::create(“Fire_Progress.png”));
shootingTime->setPosition(ccp(520,718));
// 设置进度条的样式
shootingTime->setType(kCCProgressTimerTypeBar);
// 设置进度条的值的范围【0 100】
shootingTime->setPercentage(100);
// 设置计时器运动方向
shootingTime->setMidpoint(ccp(1,0));
// 设置计时器的宽度起始比例
shootingTime->setBarChangeRate(ccp(1,0));
// 设置动作
shootingTime->setReverseProgress(true);
to2 = CCProgressTo::create(5,50);
shootingTime->runAction(CCRepeatForever::create(to2)); 在这一句就是设置无限循环
shootingTime->
addChild(shootingTime,3);

shootingTime->runAction(CCRepeatForever::create(to2)); 这个如何设成非循环

#2

shootingTime->runAction(to2);
