描述

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);
        }
    }
