LabelAtlas

abelAtlas

Introduction

CCLabelAtlas was the 1st fast label added into cocos2d. But it was superseded by CCBitmapFontAtlas.It is being maintained for backwards compatibility, but you should use CCBitmapFontAtlas instead.

Creating a LabelAtlas

CCLabelAtlas *label = [CCLabelAtlas labelAtlasWithString:@"Hello World" charMapFile:@"tuffy_bold_italic-charmap.png" itemWidth:48 itemHeight:64 startCharMap:' '];
[self add:label];

• charMapFile is an image file that contains all the characters. Each character should be ordered according to its ASCII value and the image can't contain more than 256 characters.
• itemWidth is the width of the characters in pixels
• itemHeight is the height of the characters in pixels
• startCharMap is the first character of the map.
