Handles.DrawPolyLine

描述

Draw a line going through the list of all points.

注意：如果您希望拥有恒定屏幕大小的手柄，请使用 HandleUtility.GetHandleSize。

\ 连接场景视图中所有对象的折线。

// 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

@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);
    }
}

//ConnectedPolyLine.js

var polyLineObjs : GameObject[];
