Where did you find information on what to type in for ... fntFile:@"bitmapFontTest.fnt"];

@apukumarghose mega bump. I use CCBitmapFontAtlas since it doesn't take tons of memory to constantly update.

updated score is viewed when i run the game next time. it's not appearing at the run time when it is currently running. any solution?

^ Did you read this ? http://www.cocos2d-iphone.org/wiki/doku.php/prog_guide:labels

Basically you use LabelAtlas (or BitmapFontAtlas) to display text that is updated frequently (like score or timer). And Label for text that doesn't change often or at all.

May I ask ? when we should use AtlasLabel and when to just use Label? which one is faster and lighter ( consume less memory ).???

Thanks

Thanks!

I'll try that.

Just make the characters in the charmap file big enough. Or use the scale property to make the label bigger (although you will get some pixellation that way).

Hi guys,

Is there any way to make LabelAtlas to take 50% or more of the iphone screen?

Thanks!

Thanks, I'll try to do it this way.

@osiris Yes, it's a possibility too. It didn't do it in my game because of the way I designed it, but it's a good idea.

Hi,

I have 10 scenes, each of them has separate interface, I figured it out how to
use labelAtlas to display it, but I'm stuck with implementing update function. Should I create global function to do this?

Please advise.

Thanks!

@ob1 - why not trigger the score update in the function that increments the score tally? then its not being checked every clock tick.

Thanks for suggestions!

I'll try that.

What I do is that I separated the model (the score) and the view (the label).

The view part has something like:

- step:(ccTime) dt
{
 if (previousScore != model.score)
 {
  NSString *str = [NSString stringWithFormat:@"%i", model.score];
  [myScoreLabel setString:str];
 }
}

A NSNotification might also be something to look into.

yes - use AtlasLabel if possible

Sounds logical, I'll try that.

Thanks!

You don't want to update the label that often, because changing the label is as expensive as creating a new sprite (unless it's an atlas label). You want to set up an update method and call it only when the score needs to be updated. It will not update automaticslly, you need to call [label setString:yourStringHere] on it every time you want to update it. But definitely do not re-draw it every frame.

I tried that, it get's updated only after game runs at least once. How can I use something
like cocos fps display where fps stays throughout all game?

Thanks!

"I tried to use label and AtlasLabel, but it does not get updated, it just displays zero."

Assuming score is an integer, try:

NSString *str = [NSString stringWithFormat:@"%i", score];
[myScoreLabel setString:str];

What is the best way to implement local scores to show on each scene?

Should I use label or AtlasLabel?

I tried to use label and AtlasLabel, but it does not get updated, it just displays zero.

Thanks!

Hey Codemattic,
That was it. I must have totally missed that last night!
Thanks a lot

@pabloruiz55 It should be auto-retained when added to scene/layer

I think Codemattic is right. Keep in mind that kTagBitmapAtlas1 is just a number, and you probably gave same number to some AtlasSpriteManager somewhere in your code...

Shouldn't he be retaining the BitmapFontAtlas ?

are you sure you havent added anything else with the equivalent to the kTagBitmapAtlas1 tag?

your code seems good to me.
put this:

NSLog(@"who are you: %@", label1);

right before [label1 setSTring:string];

For some reason, label1 is treated as an AtlasSpriteManager and not as BitmapFontAtlas.

BitmapFontAtlas is a subclass of AtlasSpriteManager.

Hey all so im trying to display a bitmapfontAtlas. It works perfectly to display it but when i try to update it, it crashes. here is what i have

-(void) displayScore {

	BitmapFontAtlas *label1 = [BitmapFontAtlas bitmapFontAtlasWithString:@"SCORE:" fntFile:@"IceAge3.fnt"];

	label1.anchorPoint = ccp(0,0);
	[self addChild:label1 z:0 tag:kTagBitmapAtlas1];

	CGSize s = [[Director sharedDirector] winSize];
	label1.position = ccp( s.width/2, s.height/2);

}

This displays fine but then in my game loop i have updateScore and this:

-(void) updateScore {
	int score = [GlobalDataManager sharedDataManager].currentScore;
	NSString *string = [NSString stringWithFormat:@"SCORE: %i", score];
	NSLog(@"%@", string);
	BitmapFontAtlas *label1 = (BitmapFontAtlas*) [self getChildByTag:kTagBitmapAtlas1];
	[label1 setString:string];
}

It crashes on:
[label1 setString:string];
with:

*** -[AtlasSpriteManager setString:]: unrecognized selector sent to instance 0xe6d540
2009-07-28 01:13:36.352 SnowFight[62234:20b] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[AtlasSpriteManager setString:]: unrecognized selector sent to instance 0xe6d540'

Im sure I made a stupid mistake somewhere but i copied and pasted this from the cocos2d project.

Thanks

jonathan0382, that works! I did a spotlight search for "java web start", but I guess it doesnt search /System/Library/CoreServices

riq, I didnt try yours, the -kill looked scary, but Im sure it would of worked too. :)

thanks guys

Ok, here's a fix I found. The source is listed below.

Open this:/System/Library/CoreServices and click on Java Web Start.

After this the .jnlp opens fine in both firefox and safari.

@codemattic:

/System/Library/Frameworks/ApplicationServices.framework/Framework/LaunchServices.framework/Support/lsregister -kill -r -domain local -domain system -domain user

you know whats weird - when I click on it in Firefox it asks if I want to open it in Java Web Start (default) - so I click OK - but it opens in Dashcode. I cant find JWS on my computer - I used to have it. Could the newer XCode versions have uninstalled it? Sorry jonathan0382, this used to work for me, but now it doesnt. Anybody else having this problem?
