Cocos2D菜单按钮

Question

我想从使图像中的玩家从当前场景（游戏场景）回到菜单场景，重置当前场景（游戏场景）的按钮。

Answer 1

使用如下代码：

-(void)showBackBtnMenu 
{ 
    CCSprite *backButtonNormal = [CCSprite   spriteWithSpriteFrameName:@"btnBackNormal.png"]; //Make sure u already added this sprite sheet. Otherwise use sprite from file. 
    CCSprite *backButtonSelected = [CCSprite spriteWithSpriteFrameName:@"btnBackSelected.png"]; 

    CCMenuItemSprite *backButton = [CCMenuItemSprite itemFromNormalSprite:backButtonNormal selectedSprite:backButtonSelected disabledSprite:nil target:self selector:@selector(backBtnPress:)]; 

    backButton.position = ccp(63.0f, 34.0f); 

CCMenu *menu = [CCMenu menuWithItems:backButton, nil]; 
    menu.position = ccp(0,0); 
    [self addChild:menu z:3]; //Make sure this z value is higher than ur background 
} 


-(void)backBtnPress:(id)sender 
{ 
     [[CCDirector sharedDirector] replaceScene:[transition transitionWithDuration:duration scene:[MyMainMenu scene]]]; 
}
