as3.0中如何画两点间的虚线

最好是函数形式，直接输入两点坐标就可以画出的。
求高手写出这个函数！！！！！！！！

你可以使用画直线的API，把直线切成线段，一段一段地画。

as3没有提供这样的API，自己写 再看看别人怎么说的。

这个需要自己写啦

import flash.geom.Point; function drawDashed(graphics:Graphics, beginPoint:Point, endPoint:Point, width:Number, grap:Number):void { if (!graphics || !beginPoint || !endPoint || width <= 0 || grap <= 0) return; var Ox:Number = beginPoint.x; var Oy:Number = beginPoint.y; var radian:Number = Math.atan2(endPoint.y - Oy, endPoint.x - Ox); var totalLen:Number = Point.distance(beginPoint, endPoint); var currLen:Number = 0; var x:Number, y:Number; while (currLen <= totalLen) { x = Ox + Math.cos(radian) * currLen; y = Oy +Math.sin(radian) * currLen; graphics.moveTo(x, y); currLen += width; if (currLen > totalLen) currLen = totalLen; x = Ox + Math.cos(radian) * currLen; y = Oy +Math.sin(radian) * currLen; graphics.lineTo(x, y); currLen += grap; } } this.graphics.lineStyle(1,0xFF0000) drawDashed(this.graphics, new Point(10,10), new Point(200,200), 15, 20)
