如何从形状/图形对象读取数据 [英] How to read data from shape/graphics object

问题描述

在我的项目中，我想要使用actionscript 3获取存储在Flash中的形状/图形对象中的数据能够绘制一个形状，然后读取所有形状的点到我的脚本。原因是我需要从这些点生成线，我稍后可以用来检查我的角色速度是否与其中任何一个相交。

解决方案<您可以阅读Shape的所有部分。添加到Flash Player 11.6中的新功能 和AIR 3.6：

$ p $ flash.display.Grapics.readGraphicsData（）

例子：

  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）;

要使用新版本，您必须更新playerglobal.swc

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

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.

解决方案

You can read all parts of Shape.

New feature added to Flash Player 11.6 and AIR 3.6:

flash.display.Grapics.readGraphicsData()

http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/display/Graphics.html#readGraphicsData%28%29

Example:

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);

To use the new version, you have to update playerglobal.swc
