newcc.DrawNode()创建draw对象，画点，线段，多边形




vardrawNode=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,0)!important">//同上

drawNode.drawCircle(center,radius,angle,drawLinetoCenter,0)!important">//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,0)!important">//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));

drawNode.drawQuadBezier(origin,control,0)!important">//画二次贝塞尔曲线参考三次贝塞尔曲线

drawNode.drawDot(pos,0)!important">//画点

//drawNode.drawDot(cc.p(60,20,cc.color(0.5,0.6,1));

drawNode.drawDots(points,0)!important">//画点points点数组

drawNode.drawpoly(verts,fillColor,0)!important">//画多边形

drawNode.drawRect(origin,lineColor)//画矩形

drawNode.drawSegment(from,to,color)
