cocos2d-x 3.0开发笔记---用progressTimer制作血槽

1.RADIAL

<pre name="code" class="cpp">Sprite *bgSprite = Sprite::create("red.png");
addChild(bgSprite, 1, 1);
Sprite *hpSprite = Sprite::create("green.png");
progressTimer = ProgressTimer::create(hpSprite);
progressTimer->setType(ProgressTimer::Type::RADIAL);
progressTimer->setReverseProgress(true);
progressTimer->setPercentage(30);//满值 100%
addChild(progressTimer, 0, 0);

2.BAR

Sprite *bgSprite = Sprite::create("box.png");
addChild(bgSprite, 1, 1); 
Sprite *hpSprite = Sprite::create("hp.png"); 
progressTimer = ProgressTimer::create(hpSprite); 
progressTimer->setType(ProgressTimer::Type::BAR);
//从左到右 
progressTimer->setMidpoint(ccp(0, 0.5f)); 
progressTimer->setBarChangeRate(ccp(1, 0)); 
//从右到左 
// progressTimer->setMidpoint(ccp(1, 0.5f));
// progressTimer->setBarChangeRate(ccp(1, 0)); 
//从上到下 
// progressTimer->setMidpoint(ccp(0.5f, 1)); 
// progressTimer->setBarChangeRate(ccp(0, 1)); 
//从下到上 
// progressTimer->setMidpoint(ccp(0.5f, 0)); 
// progressTimer->setBarChangeRate(ccp(0, 1)); 
//progressTimer->setMidpoint(Point(0, 0.5f));
//progressTimer->setBarChangeRate(Point(1, 0));
//progressTimer->setPercentage(30);//满值 100% 
//addChild(progressTimer, 0, 0);
