This will get you all positions in a webwalking path, I guess you could use path.length()
WebWalkEvent event = new WebWalkEvent(position);
event.prefetchRequirements(script);
Position[] path = event.getPositions();
I'm pretty sure GraphicsObjects is just everything that has a model and can be rendered. I'm not sure what the teleport thingy is though, isn't it just some animation?
Works fine for me, tested on a few accounts on 3 machines so I have no idea.
Try restarting your client or something and let me know it this keeps happening
Or check your Controls settings in game, do you have hotkeys set?
