我正在尝试使用以下代码对 CCMenuItem 进行子类化:
通用按钮.h
#import <Foundation/Foundation.h>
#import "cocos2d.h"
@interface GenericButton : CCMenuItemSprite {
}
+(id) itemwithTitle:(NSString*)title withBGColor: (ccColor3B) bgColor andFGColor:(ccColor3B)fgColor;
@end
通用按钮.m
#import "GenericButton.h"
#import "HelpfulClasses.h"
@implementation GenericButton
+(id) itemwithTitle:(NSString*)title withBGColor: (ccColor3B) bgColor andFGColor:(ccColor3B)fgColor{
CCSprite*genericButtonBG = [CCSprite spriteWithSpriteFrameName:@"genericButtonBG.png"];
genericButtonBG.color=bgColor;
CCSprite*genericButtonBGPressed = [CCSprite spriteWithSpriteFrameName:@"genericButtonBGPressed.png"];
genericButtonBGPressed.color=bgColor;
CCMenuItemSprite*button = [CCMenuItemSprite itemWithNormalSprite:genericButtonBG selectedSprite:genericButtonBGPressed];
CCSprite*fgButton = [CCSprite spriteWithSpriteFrameName:@"genericButton.png"];
fgButton.color=fgColor;
[button addNodeInMiddleOfParent:fgButton];
CCLabelBMFont *buttonTitle = [CCLabelBMFont labelWithString:title fntFile:@"font.fnt"];
if ([title length]>7) {
buttonTitle.scale=0.85;
}
buttonTitle.color=ccYELLOW;
[fgButton addNodeInMiddleOfParent:buttonTitle];
return button;
}
// on "dealloc" you need to release all your retained objects
- (void) dealloc
{
// in case you have something to dealloc, do it in this method
// in this particular example nothing needs to be released.
// cocos2d will automatically release all the children (Label)
// don't forget to call "super dealloc"
[super dealloc];
}
@end
但是每当我使用 GenericButton*button = [GenericButton item....] 时,在 CCScene 中,有很多“removeChildByTag: child not found!” 显示在控制台上。难道我做错了什么?干杯
