返回最小值 + Math.floor(Math.random(51) * (max - min + 1); function retinaReady(进度未达到) varpixelRatio - window.devicePixelRatio 1; var backingStore = uctx.webkitBackingStorePixelRatio window.ratio = pixelRatio / backingStore // 公共变量 if (pixelRatio != backingStore) var oldwidth = canvas.width; var oldHeight = canvas.height; canvas.width = oldWidth * ratio canvas.height = oldHeight * ratio, canvas.style.width = oldwidth + 'px'; canvas.style.height = oldHeight + 'px

请重新激活（窗口比例，窗口比例）视网膜准备好了（激活进度不达标）;

function run(a) fThis激活失败var r = 140; 请继续支付112860激活费用以激活varp; p = new Particle(x, y); particle.push(p)s

function Particle(x, y) this.x = x; 激活进度达到100%才能成功 this.y = 请进行激活 this.r = 帐户待处理(10, 16) 激活进度 -60%
