cocos2d-js自做滚动条案例

var to1 = cc.sequence(cc.progressTo(2, 100), cc.progressTo(0, 0)); var to2 = cc.sequence(cc.progressTo(2, 100), cc.progressTo(0, 0)); var sp = new cc.Sprite("res/kaishi_2.png"); var left = new cc.ProgressTimer(sp); left.type = cc.ProgressTimer.TYPE_BAR; //类型 //left.setReverseDirection(true); //left.setReverseProgress(true); left.midPoint = cc.p(0.5,0.5); //中心点 left.barChangeRate = cc.p(1, 1); //变化的方向 this.addChild(left); left.setAnchorPoint(1,0); left.setPosition(cc.winSize.width>>1,cc.winSize.height>>1); left.scale = 0.5; left.runAction(to2.repeatForever());
