Rewrote the Ammomenu: Added landscape ammomenu At the moment MOBILE indicates landscape, but we could just as easily make a variable out of it Draw to texture once uVariables.AmmoMenuInvalidated indicates a new ammo menu needs to be drawn, see uTeams and uAmmos Slot/Cellsize is dependent on uConsts.AMSlotSize this should make it easier to scale the ammo menu on smaller screens AmmoRect AmmoRect indicates where and how big the ammo menu is, this makes positioning a bit easier imo, because you only need to change the position at one single point needs testing on the iphone (and other systems as well ofcourse..)
