Working Example of Using CCBitmapFontAtlas

[GoogleCodeExporter]

Hi, 

I am looking for a simple example of how to work with CCBitmapFontAtlas. I have 
tried using something similar to the code below but I keep getting the errors I 
posted below.

I searched all over for an example of a successful implementation, but have 
been unable to find one.

public class GameLayer extends CCColorLayer
{
  protected CCBitmapFontAtlas scoreLabel;

 protected GameLayer(ccColor4B color, Context ctx)
 {
  super(color);     
  mContext = ctx;
  Context context = CCDirector.sharedDirector().getActivity();
  this.setIsTouchEnabled(true);
  CGSize winSize = CCDirector.sharedDirector().displaySize();
  scoreLabel = CCBitmapFontAtlas.bitmapFontAtlas(null, "ArnoPro24.fnt");
 }
}

I get the following in Log Cat

I was able to resolve the problem. I needed to use one of the editors listed in 
the CCBitmapFontAtlas.java file.

Supported editors:
  - http://www.n4te.com/hiero/hiero.jnlp
  - http://slick.cokeandcode.com/demos/hiero.jnlp
  - http://www.angelcode.com/products/bmfont/

I had used the same files I used in my iOS app and they didn't work. I forget 
which app I used to create the BitmapFontAtlas, but using Heiro worked the best 
for me.

Is it possible to support the tool "GlyphDesigner" I use in Mac OS X, and I 
work it fine in cocos2d-iphone with CCLableBMFont class.

I've try and work with GlyphDesigner was successful, 
scoreLabel = CCBitmapFontAtlas.bitmapFontAtlas(null, "ArnoPro24.fnt");  
//cannot put null, instead of you should put the score's text here.

CharSequence score = "10000";
scoreLabel = CCBitmapFontAtlas.bitmapFontAtlas(score, "ArnoPro24.fnt");
