This is very simple. Using the Fog of War script (http://rmrk.net/index.php/topic,5825.0.html), the fog also covers things like an equipment bar. I haven't checked with the Passabillity Minimap and custom HP bar script yet, but I don't excactly need FOW for my game, so I haven't yet. Will in a minute, so bear with me...
Okay, the minimap is saved, but what about the HP bar (I'll get a link in another minute or two...)?
