Handles.DrawPolyLine

Other Versions
public static void DrawPolyLine(params Vector3[] points);

Description

Draw a line going through the list of all points.

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


PolyLine that connects all the objects in the Scene View.

    // 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);
        }
    }

And the script attached to this handle:

    //ConnectedPolyLine.js

    var polyLineObjs : GameObject[];
