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

来源：互联网发布：校园网络需求验证编辑：程序博客网时间：2024/05/17 02:52

血条经常会用到，没必要重复编写浪费时间，这里用最新版的API写个，方便以后调用。

以下代码使用的引擎版本是cocos2d-x 3.0rc0

1.RADIAL

cocos2d-x

<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);
