Changeset 6718 for code/branches/gamestates2

Timestamp:

Apr 13, 2010, 3:55:30 PM (15 years ago)

Message:

Moved BasicGUI.lua to GUISheet.lua and derived MenuSheet.lua as well as HUDSheet.lua from it.
Also, to make a new GUI sheet, use either createHUDSheet or createMenuSheet.
Also removed bShowCursor from the showGUI function. This is now always a value directed by the GUI sheet.
