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..)
