Changeset 1604 for code/branches/hud

Timestamp:

Jun 15, 2008, 1:09:07 AM (16 years ago)

Author:

rgrieder

Message:

• adjusted Radar to fit in XML loading scheme
• OverlayGroup should be more or less what I imagine for now (only supports scale method to scale the entire HUD)
• singletonized HUDNavigation (and HUDRadar of course): These are temporary hacks!

Location:

code/branches/hud
