@CustomEditor(ConnectedObjects)
class ConnectLineHandle extends Editor {
	function OnSceneGUI() {
		var connectedObjects: ConnectedObjects = target as ConnectedObjects;
		if (connectedObjects.objs == null)return ;
		var center: Vector3 = connectedObjects.transform.position;
		for (var i: int = 0; i < connectedObjects.objs.Length; i++) {
			var connectedObject: GameObject = connectedObjects.objs[i];
			if (connectedObject) {
				Handles.DrawLine(center, connectedObject.transform.position);
