查找沿路径AS3的所有点 [英] Find all points along a path AS3

问题描述

基本上，我想要一个影片剪辑随机添加到沿Bezier曲线的任何一点。有没有办法找到一条路径的所有点？或者，也许有办法找到方程（这是一个二次曲线）？如果一切都失败了，有没有办法找到沿着一条直线的点（即不是完全水平或垂直）？

Basically, I want to randomly add a movie clip to any point along a bezier curve. Is there a way to find all points along a path? Or maybe there's a way to find the equation (it's a quadratic curve)? If all else fails, is there a way to find the points along a straight line (that isn't perfectly horizontal or vertical)?

推荐答案

如果您正在使用钢笔工具，这是创建一个图形。您可以通过从 Shape.graphics.readGraphicsData读取结果访问这种形状的路径（）

If you are using the pen tool, this is creating a Shape. You can access the path of this shape by reading the result from Shape.graphics.readGraphicsData()

请参阅参考<一href="http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/display/Graphics.html#readGraphicsData%28%29"相对=nofollow> readGraphicsData 。
