<Span style = "font-family: Arial, Helvetica, sans-serif; background-color: rgb (255,255,255);"> I checked this part of the code online, it is basically written in previous versions. You only need to change it a little. </span>

First look at the MenuScene. cpp: popupLayer () {// define a pop-up layer and input a background image PopupLayer * popDialog = PopupLayer: create (DIALOG_BG ); // ContentSize is an optional setting and can be left unspecified. If it is set as a 9-figure zoom popDialog-> setContentSize (CCSizeMake (Quit_Dialog_Size_Width, Quit_Dialog_Size_Height )); popDialog-> setTitle (DIALOG_TITLE); popDialog-> setContentText (DIALOG_CONTENT, 20, 60,250); // set the callback function, callback returns a CCNode to get the popDialog button clicked for tag judgment-> setCallbackFunc (this, callfuncN_selector (MenuScene: quitButtonCallback); // Add button, set the image, text, tag Information popDialog-> addButton (BUTTON_BG1, BUTTON_BG3, OK, success); popdig1-> addButton (success, BUTTON_BG3, CANCEL, success); this-> addChild (popDialog ); // Add to current layer}

PopupLayer. h and PopupLayer. cpp are the code in the pop-up dialog box:

First look at PopupLayer. h

Const int Pop_FontSize = 20; // defines the font size class PopupLayer: public Layer {static PopupLayer * create (const char * backgroundImage ); // create the object void setTitle (const char * title, int fontsize = Pop_FontSize) based on the background image; // set the dialog box title void setContentText (const char * text, int fontsize = Pop_FontSize, int padding = 50, int paddintTop = 100); // set the dialog box text content void setCallbackFunc (Object * target, SEL_CallFuncN callfun); // set the callback method bool addButton (c Onst char * normalImage, const char * selectedImage, const char * title, int tag = 0); // press the button in the Add dialog box. If you are sure to cancel virtual void onEnter (); // call virtual void onExit () when entering; // void buttonCallback (CCObject * pSender); int m_contentPadding; // the gap between the two sides of the text content and int m_contentPaddingTop; // The blank area above the text is located at CCObject * m_callbackListener; SEL_CallFuncN m_callback; // defines the variable CC_SYNTHESIZE_RETAIN (Menu *, m _ pMenu, MenuButton) with the retain attribute _ RETAIN (Sprite *, m _ sfBackGround, SpriteBackGround );.........................};

The code for PopupLayer. cpp is as follows:

PopupLayer: PopupLayer (): m _ pMenu (NULL), m_contentPadding (0), m_contentPaddingTop (0), m_callbackListener (NULL), m_callback (NULL ), m _ sfBackGround (NULL), m _ s9BackGround (NULL), m _ ltContentText (NULL), m _ ltTitle (NULL) {}// release the variable PopupLayer :: ~ PopupLayer () {CC_SAFE_RELEASE (m _ pMenu); CC_SAFE_RELEASE (m _ sfBackGround); CC_SAFE_RELEASE (m _ ltContentText); CC_SAFE_RELEASE (m _ ltTitle ); CC_SAFE_RELEASE (m _ s9BackGround );}

Void PopupLayer: setCallbackFunc (cocos2d: Object * target, SEL_CallFuncN callfun) {// The method callback m_callbackListener = target; m_callback = callfun ;}

Bool PopupLayer: init () {// initialize the required Menu, and then follow up the parameters to add the Item option menu * Menu = menu: create () to the Menu (); menu-> setPosition (CCPointZero); setMenuButton (menu); setTouchMode (Touch: DispatchMode: ONE_BY_ONE); auto listener = EventListenerTouchOneByOne: create (); listener-> setSwallowTouches (true); listener-> onTouchBegan = [] (Touch * t, Event * e) {CCLog ("PopupLayer touch"); return true ;}; _ eventDispatcher-> addEventListenerWithSceneGraphPriority (listener, this); // shield the lower-layer Event Response return true ;}

Add the MenuItem option bool PopupLayer: addButton (const char * normalImage, const char * selectedImage, const char * title, int tag) based on the parameter, title, tag, and image effect) {Size winSize = CCDirector: getInstance ()-> getWinSize (); Point pCenter = ccp (winSize. width/2, winSize. height/2); // create the MenuItem button and set the callback method MenuItemImage * menuImage = MenuItemImage: create (normalImage, selectedImage, this, menu_selector (PopupLayer: buttonCallback )); menuImage-> setTag (tag); menuImage-> setPosition (pCenter); // Add text instructions to MenuItem and set the position Size imenu = menuImage-> getContentSize () in MenuItem (); labelTTF * ttf = LabelTTF: create (title, "", 20); ttf-> setColor (ccc3 (0, 0, 0 )); ttf-> setPosition (ccp (imenu. width/2, imenu. height/2); menuImage-> addChild (ttf); getMenuButton ()-> addChild (menuImage); return true;

Now let's take a look at the callback method buttonCallback of MenuItem.

Void PopupLayer: buttonCallback (cocos2d: CCObject * pSender) {Node * node = dynamic_cast <Node *> (pSender); CCLog ("touch tag: % d ", node-> getTag (); if (m_callback & m_callbackListener) {(m_callbackListener-> * m_callback) (node); // This calls setCallbackFunc () method passed in the MenuScene object's quitButtonCallback () method} this-> removeFromParent (); // remove the dialog box from the parent node}

Call the onEnter method to initialize the interface before the dialog box is displayed.

Void PopupLayer: onEnter (){....................... Size contentSize; // set the background of the dialog box. The code is omitted. // Add the button and set its location this-> addChild (getMenuButton (); float btnWidth = contentSize. width/(getMenuButton ()-> getChildrenCount () + 1); Vector <Node *> vecArray = getMenuButton ()-> getChildren (); int j = 0; for (auto it = vecArray. begin (); it! = VecArray. end (); it ++) {Node * node = dynamic_cast <Node *> (* it); node-> setPosition (Point (winSize. width/2-contentSize. width/2 + btnWidth * (j + 1), winSize. height/2-contentSize.height/3); j ++;} // the title of the displayed dialog box is omitted. // The Action * popupLayer = Sequence: create (ScaleTo :: create (0.0, 0.0), ScaleTo: create (0.15, 1.05), ScaleTo: create (0.08, 0.95), ScaleTo: create (0.08, 1.0), NULL ); this-> runAction (popupLayer );}

Code is written a little more. To facilitate testing, I upload the Code as follows:
