进度条特效

效果图：

代码：

//条形进度条
void LoginScene::progressBarTest()
{
	//背景
	Sprite* spBg = Sprite::create("room/21dian/gamescene/img_xz_bg.png");
	spBg->setVisible(true);
	spBg->setPosition(Vec2(960, 400));
	csb->addChild(spBg);

	//进度
	Sprite* spJd = Sprite::create("room/21dian/gamescene/img_xz_js.png");
	spJd->setVisible(true);

	//控件
	auto progressTimer = ProgressTimer::create(spJd);
	progressTimer->setPosition(spBg->getPosition());
	progressTimer->setType(ProgressTimer::Type::BAR);//BAR条形，RADIAL扇形

	//----从右到左
	progressTimer->setMidpoint(ccp(0, 0.5));
	progressTimer->setBarChangeRate(ccp(1, 0));
	////----从左到右
	//progressTimer->setMidpoint(ccp(1, 0.5));
	//progressTimer->setBarChangeRate(ccp(1, 0));
	////----从下到上
	//progressTimer->setMidpoint(ccp(0.5, 1));
	//progressTimer->setBarChangeRate(ccp(0, 1));
	////----从上到下
	//progressTimer->setMidpoint(ccp(0.5, 0));
	//progressTimer->setBarChangeRate(ccp(0, 1));

	//
	progressTimer->setPercentage(100);
	csb->addChild(progressTimer);

	////创建进度动作CCProgressTo、CCProgressFromTo
	////进度动作
	//CCProgressTo* ac1 = CCProgressTo::create(2.0f, 100);
	//progressTimer->runAction(CCRepeatForever::create(ac1)); //2秒内，从0到100
	CCProgressFromTo* ac2 = CCProgressFromTo::create(10.0f, 100, 0);
	progressTimer->runAction(CCRepeatForever::create(ac2));//10秒内，从100到0

	//反进度显示setReverseProgress()
	//progressTimer->setReverseProgress(true); //反进度显示
	//progressTimer->setReverseProgress(true); //逆时针

}
