Hey, 2 quick questions:
1) Is there a way in v0.8.x to do something like BitmapItemAtlasFont or something, similar to the existing MenuItemAtlasFont?
2) Is there a link to the 0.8 api docs? The current stuff is 0.7.3, obv, and I can't seem to find a link the 0.8 beta docs.
thanks!

You can very easily use BitmapFontAtlasses in a menu:
BitmapFontAtlas *playLabel = [[BitmapFontAtlas alloc] initWithString:@"Play" fntFile:@"menu-white.fnt"];
MenuItem *playItem = [MenuItem itemWithLabel:playLabel target:self selector:@selector(menuCallbackPlay:)];

I was working with some of the test examples tonight and one behavior I noticed was that if I reduce the scale of the MenuItemLabel when I first build the Menu, when the MenuItem is touched in the Simulator, there is the bouncing animation and the scale is restored to the default size.
Am I setting the scale incorrectly here? My initialization code is as follows:
BitmapFontAtlas *startGameBFA = [BitmapFontAtlas bitmapFontAtlasWithString:@"Start Game" fntFile:@"bitmapFontTest2.fnt"];
BitmapFontAtlas *loadGameBFA = [BitmapFontAtlas bitmapFontAtlasWithString:@"Load Game" fntFile:@"bitmapFontTest2.fnt"];
BitmapFontAtlas *helpBFA = [BitmapFontAtlas bitmapFontAtlasWithString:@"Help" fntFile:@"bitmapFontTest2.fnt"];
MenuItemLabel *startGameMenuItem = [MenuItemLabel itemWithLabel:startGameBFA target:self selector:@selector(startGame:)];
MenuItemLabel *loadGameMenuItem = [MenuItemLabel itemWithLabel:loadGameBFA target:self selector:@selector(foo:)];
MenuItemLabel *helpMenuItem = [MenuItemLabel itemWithLabel:helpBFA target:self selector:@selector(help:)];
[startGameMenuItem setScale:.5];
[loadGameMenuItem setScale:.5];
[helpMenuItem setScale:.5];
Menu *menu = [Menu menuWithItems:startGameMenuItem, loadGameMenuItem, helpMenuItem, nil];
[menu alignItemsVertically];
[self addChild:menu];
I am trying to use bitmapfontatlas in a menu using cocos2d 0.72, it works fine, but i get leaks:
in bitmapFontAtlasWithString
I am doing just as in the examples in 0.8, so i must assume something has to be changed so it does not leak in 0.7x.
any idea?
Yes sorry, i was wrong, i am using 0.8 beta.
the code i am using is the following:
BitmapFontAtlas *label = [BitmapFontAtlas bitmapFontAtlasWithString:@"Start Game" fntFile:@"fontfinal.fnt"];
BitmapFontAtlas *label2 = [BitmapFontAtlas bitmapFontAtlasWithString:@"HighScores" fntFile:@"fontfinal.fnt"];
BitmapFontAtlas *label3 = [BitmapFontAtlas bitmapFontAtlasWithString:@"Instructions" fntFile:@"fontfinal.fnt"];
BitmapFontAtlas *label4 = [BitmapFontAtlas bitmapFontAtlasWithString:@"Credits" fntFile:@"fontfinal.fnt"];
MenuItemLabel *start = [MenuItemLabel itemWithLabel:label
target:self
selector:@selector(startGame:)];
MenuItemLabel *highScores = [MenuItemLabel itemWithLabel:label2
target:self
selector:@selector(highScores:)];
MenuItemLabel *help = [MenuItemLabel itemWithLabel:label3
target:self
selector:@selector(help:)];
MenuItemLabel *about = [MenuItemLabel itemWithLabel:label4
target:self
selector:@selector(about:)];
Menu *menu = [Menu menuWithItems:start,highScores,help,about, nil];
[menu alignItemsVerticallyWithPadding:13];
[menu setPosition:ccp(132,102)];
//[menu setOpacity:50];
[self addChild:menu];Instruments shows 54 leaks.
50 from bitmapFontAtlasWithString
and 4 from menuItemLabel initWithTarget
@pablo: could you try with v0.8-final ? thanks.
@riq: i have just updated, i am still getting some leaks. Specifically in:
Menuitem initwithTarget method
in line:
invocation = [NSInvocation invocationWithMethodSignature:sig];
@pablo: it might be a bug, but it seems that the NSInvocation is being released in dealloc.
your code seems to be ok.
the best way to know if it is leaking is by running your game in debug mode (add the DEBUG=1 preprocessor definition on your project), or in cocos2d.h just add this line:
#define DEBUG=1and then view the console. you should see lot's of messages like:
deallocing XXX
If you don't see a "deallocing BitmapFontAtlas" message, then the bitmapFontAtlas is not being released. This can be a cocos2d bug, or a bug in your code.
@Riq: Just tried that, and i didn't see a "deallocing BitmapFontAtlas"
I have just solved this by making the labels instance variables and by releasing them on dealloc.
Hi everyone, I have succesfully made my Menu using BitmapAtlasFont, but I have another problem, in that the MenuItems don't respond very well to touches. It takes a few goes to make the button respond, and it seems you need to touch at only certain parts of the text in the MenuItem.
Has anyone else experienced this?
Cheers
Tom
