快讯：如何阅读从形状/图形对象数据 [英] Flash : How to read data from shape/graphics object

问题描述

你好，

我想知道是否有可能获得存储在形状中的数据/图形对象？

I am wondering if it is possible to get the data that is stored in a shape/graphics object in flash using actionscript 3?

在我的项目，我想能够绘制形状，然后读取该形状的所有点到我的脚本。这其中的原因是，我需要去生成这些点的线，我以后可以用它来检查我的人物速度相交任何人。

In my project I would like to be able to draw a shape and then read all the points in that shape into my script. The reason for that is that I need go generate lines from those points that I later can use to check if my characters velocity intersects with any of them.

问候，

推荐答案

您可以阅读形状的所有部分。

例如：

var s :Shape = new Shape();
s.graphics.lineStyle(2, 0xFF0000);
s.graphics.drawCircle(0, 0, 50)

var gd:Vector.<IGraphicsData> = s.graphics.readGraphicsData(false);

var copy_of_s :Shape = new Shape();
copy_of_s.graphics.drawGraphicsData(gd);

addChild(copy_of_s);
