Description

Draw a line from p1 to p2.


Draw Line 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 object to 0,0,0.
	
	@CustomEditor (ConnectedObjects)
	class ConnectLineHandle extends Editor {
	
	    function OnSceneGUI () {
	    	for(var i = 0; i < target.objs.Length; i++)
	    		if(target.objs[i])
	    			Handles.DrawLine(target.transform.position, 
	    						target.objs[i].transform.position);
	    		else
	    			Handles.DrawLine(target.transform.position, Vector3.zero);
	    }
	}
And the script attached to this Handle:
