Handles.DrawAAPolyLine 绘制AA多段线

static function DrawAAPolyLine (params points : Vector3[]) : void
static function DrawAAPolyLine (width : float, params points : Vector3[]) : void
static function DrawAAPolyLine (lineTex : Texture2D, params points : Vector3[]) : void
static function DrawAAPolyLine (lineTex : Texture2D, width : float, params points : Vector3[]) : void

Parameters参数

• lineTex
  The AA texture used for rendering. To get an anti-aliased effect use a texture that is 1x2 pixels with one transparent white pixel and one opaque white pixel.
  AA纹理用于渲染。为了得到一个消除锯齿的效果，使用是一个透明的白色像素和一个不透明的白色像素的1X2像素的纹理。
• width
  The width of the line. Note: Use HandleUtility.GetHandleSize where you might want to have constant screen-sized handles.
  线的宽度。注意：使用HandleUtility.GetHandleSize你可能希望有恒定屏幕大小的控制柄。
• points
  List of points to build the line from.
  用来构建线点的列表

Description描述

Draw anti-aliased line specified with point array and width.

绘制指定的抗锯齿线带有点的数组和宽度。

Note: Use HandleUtility.GetHandleSize where you might want to have constant screen-sized handles.

注意：使用HandleUtility.GetHandleSize你可能希望有恒定屏幕大小的控制柄。

PolyLine that connects all the objects in the Scene View.
在场景视图多段线连接所有物体。

// Draw lines to the connected game objects that a script has.
// if the target object doesnt have any game objects attached
// then it draws a line from the Last checked object to 0,0,0
//绘制线用来连接带有脚本的物体
//如果目标物体没有任何物体被附加，然它绘制一条线从物体到0,0,0
@CustomEditor (ConnectedPolyLine)
class ConnectedPolyLineHandle extends Editor {

	var positions : Vector3[];

	function OnSceneGUI () {
		if(target.polyLineObjs.Length > 0)
		positions = new Vector3[target.polyLinesObjs.Length];
		for(var i = 0; i < target.polyLineObjs.Length; i++)
			if(target.polyLineObjs[i])
				positions[i] = target.polyLineObjs[i].transform.position;
			else
				positions[i] = Vector3.zero;
			Handles.DrawPolyLine(positions);
	}
}

And the script attached to this Handle:

该脚本附加到这个控制柄物体：

//ConnectedPolyLine.js

var polyLineObjs : GameObject[];
