   Hi

   I have a question regarding the use of the BitmapFontAtlas. I have a menu with a couple of menu items.

   BitmapFontAtlas *label1 = [BitmapFontAtlas bitmapFontAtlasWithString:@"Option 1" fntFile:@"bitmapFont.fnt"];
   MenuItemLabel *item1 = [MenuItemLabel itemWithLabel:label1 target:self selector:@selector(menuCallback1:)];
   
   BitmapFontAtlas *label2 = [BitmapFontAtlas bitmapFontAtlasWithString:@"Option 2" fntFile:@"bitmapFont.fnt"];
   MenuItemLabel *item2 = [MenuItemLabel itemWithLabel:label2 target:self selector:@selector(menuCallback2:)];

   I was wondering if this is the correct way to do this. I mean do I really have to init the same font for every item even if it uses the same font ?

   That's not an issue. If you step into BitmapFontAtlas deep enough you'll notice that at some point there's a texture cache (don't remember the class name).

   It's basically a dictionary lookup with the string as the key. If nothing is in the dictionary for that key, texture is loaded and added under that key. Next lookup just returns the texture.

   Actually it is an issue, I think...

   Although the texture is not duplicated, the data structures for mapping from text to the characters, kerning info, etc. is all reloaded and duplicate needlessly.

   I logged an issue for this: http://code.google.com/p/cocos2d-iphone/issues/detail?id=628

   Looking at the issue now, it sounds like it might have been fixed. Riq reports some sort of BitmapFontConfiguration class that deals with this problem. I haven't investigated to see if this resolves the issue or not.
