new cc.DrawNode() 创建draw对象，画点，线段，多边形

var drawNode = new cc.DrawNode();

this.addChild(drawNode);              //加入Layer层

drawNode.clear()                      //清除节点缓存

drawNode.ctor()                       //构造函数

drawNode.drawCardinalSpline(config, tension, segments, lineWidth, color)    //曲线

//参数说明:
//congfig:点数组
//tension:张力
//segments:段落
//lineWidth:线条宽度
//color:颜色

drawNode.drawCatmullRom(points, segments, lineWidth, color)   //同上

drawNode.drawCircle(center, radius, angle, segments, drawLineToCenter, lineWidth, color)   //画圆
//参数说明: 原点，半径，弧度，分段(越大越接近圆)，原点到弧度的线(boolean)，线条宽度，颜色

drawNode.drawCubicBezier(origin, control1, control2, destination, segments, lineWidth, color)  //画三次贝塞尔曲线
//drawNode.drawCubicBezier(cc.p(s.width - 250, 40), cc.p(s.width - 70, 100), cc.p(s.width - 30, 250), cc.p(s.width - 10, s.height - 50),10,1, cc.color(0, 1, 0, 1));
drawNode.drawQuadBezier(origin, control, destination, segments, lineWidth, color)          //画二次贝塞尔曲线 参考三次贝塞尔曲线
drawNode.drawDot(pos, radius, color)         //画点
//drawNode.drawDot(cc.p(60, 100), 20, cc.color(0.5,0.6,0,1));
drawNode.drawDots(points, radius, color)     //画点  points  点数组

drawNode.drawPoly(verts, fillColor, lineWidth, color)       //画多边形
drawNode.drawRect(origin, destination, fillColor, lineWidth, lineColor)  //画矩形
drawNode.drawSegment(from, to, lineWidth, color)
