Cocos2D菜單按鈕

Question

我想從使圖像中的玩家從當前場景（遊戲場景）回到菜單場景，重置當前場景（遊戲場景）的按鈕。

Answer 1

使用如下代碼：

-(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]]]; 
}
