cocos2d分数滚动效果！

cocos2d，做了一个分数滚动的效果，cocos2d分数滚动效果！#import <UIKit/UIKit.h>#import "cocos2d.h"//#import "AWTextureFilter.h"@interface ScoreBoard :CCSprite{CCLabelTTF *label_;CCSprite *shadowLa_;long long number_;    NSString* format_;    long target_;    ccTime interval_;    NSString* fontName_;    CGFloat fontSize_;}-(id)initWithScore:(NSString*)format Number:(long long)number shadowColor:(ccColor3B)shadowColor shadowPosition:(CGPoint)shadowposition Interval:(ccTime)interval FontName:(NSString*)fontName FontSize:(CGFloat)fontSize;-(id)initWithScore:(NSString*)format Number:(long long)number;-(void)setScore:(long long)score;@end
