Cocos2d-x level selection interface (use of CCScrollView)

Today, I want to write a level selection interface.

Baidu adopts CCScrollView.

The usage of the CCScrollView is not described. Baidu. (Keyword: CCScrollView details)

Here, we mainly use an example to introduce the implementation of the menu interface.

First. As follows:

1. First from http://pan.baidu.com/share/link? Required id = 2511857370 & uk = 2685725110 download required resources

2. Import the image Resources and CCGameScrollView. h and CCGameScrollView. cpp files in the Resources folder to your project.

3. Let your class inherit CCGameScrollView and implement five pure virtual interfaces.

// The following five methods must inherit // rolling trigger virtual void scrollViewDidScroll (cocos2d: extension: CCScrollView * view); // scaling trigger virtual void scrollViewDidZoom (cocos2d: extension:: CCScrollView * view); // initialize each separate page. pPage is the container for this page. nPage is the IDvirtual bool scrollViewInitPage (cocos2d: CCNode * pScroll, cocos2d :: CCNode * pPage, int nPage); // click a page to process virtual void scrollViewClick (const cocos2d: CCPoint & oOffset, const cocos2d: CCPoint & oPoint, cocos2d :: CCNode * pPage, int nPage); // The callback that ends after each slide. You can handle some things here: virtual void scrollViewScrollEnd (cocos2d: CCNode * pPage, int nPage );

4. implement related methods.

The following describes my test classes.

LevelSelect. h

/// LevelSelect. h // RunGame // Created by Colin on 14-4-13. /// # ifndef _ RunGame _ LevelSelect __# define _ RunGame _ LevelSelect __# include
 
  
# Include "cocos2d. h "# include" CCGameScrollView. h "// import the header file using namespace cocos2d; class LevelSelectScene: public cocos2d: CCLayer, public CCCGameScrollViewDelegate {public: LevelSelectScene ();~ LevelSelectScene (); bool init (); static cocos2d: CCScene * scene (); // The following five methods must be inherited // rolling trigger virtual void scrollViewDidScroll (cocos2d: extension:: CCScrollView * view); // scaling triggers virtual void scrollViewDidZoom (cocos2d: extension: CCScrollView * view); // initializes each individual page, and pPage is the container of this page, nPage is the IDvirtual bool scrollViewInitPage (cocos2d: CCNode * pScroll, cocos2d: CCNode * pPage, int nPage) of this page. // click a page to process virtual void scrollViewClick (const cocos2d:: CCPoint & oOffset, const cocos2d: CCPoint & oPoint, cocos2d: CCNode * pPage, int nPage); // The callback that ends after each slide, here we can handle some things: virtual void scrollViewScrollEnd (cocos2d: CCNode * pPage, int nPage); CREATE_FUNC (LevelSelectScene); private: CCCGameScrollView * m_ScrollView ;}; # endif/* defined (_ RunGame _ LevelSelect __)*/
 

LevelSelect. cpp

/// LevelSelect. cpp // RunGame /// Created by Colin on 14-4-13. //// # include "LevelSelect. h "# include" SimpleAudioEngine. h "# include" GameMain. h "// main game interface using namespace cocos2d; using namespace CocosDenshion; USING_NS_CC_EXT; LevelSelectScene: LevelSelectScene () {} LevelSelectScene ::~ LevelSelectScene () {}ccscene * LevelSelectScene: scene () {CCScene * scene = CCScene: create (); LevelSelectScene * layer = LevelSelectScene: create (); scene-> addChild (layer); return scene;} // scroll triggered void LevelSelectScene: scrollViewDidScroll (CCScrollView * view) {}// scaling triggered void LevelSelectScene :: scrollViewDidZoom (CCScrollView * view) {} // initialize each separate page. pPage is the container of this page. nPage is the IDbool LevelSelectScene: scrollView of this page. InitPage (cocos2d: CCNode * pScroll, cocos2d: CCNode * pPage, int nPage) {CCString str; str. initWithFormat ("12703d.png", nPage + 1); CCSprite * sprite = CCSprite: create (str. getCString (); pPage-> addChild (sprite); return true;} // click the processing void LevelSelectScene: scrollViewClick (const cocos2d: CCPoint & oOffset, const cocos2d: CCPoint & oPoint, cocos2d: CCNode * pPage, int nPage) {switch (nPage) {case 0: {// enter The main game interface CCDirector: shareddire()-> replaceScene (CCTransitionFadeBL: create (0.5, GameMain: scene ();} break; case 1: {// scroll to a page m_ScrollView-> scrollToPage (2);} break; case 2: {// set m_ScrollView-> setCurPage (3);} break ;}} // The callback that ends after each slide. You can handle some things here. void LevelSelectScene: scrollViewScrollEnd (cocos2d: CCNode * pPage, int nPage) {CCLog ("Current Page = % d", nPage);} bool LevelSelectScene: init () {if (! CCLayer: init () {return false;} // CCScrollViewm_ScrollView = CCCGameScrollView: create (); // create a scrollviewm_ScrollView-> setDirection (kCCScrollViewDirectionHorizontal ); // set the scroll direction. Currently, only the horizontal and vertical directions are supported. // this indicates the number of pages and the size of each page (which affects the distance between pages) m_ScrollView-> createContainer (this, 5, CCSizeMake (CCDirector: sharedDirector ()-> getVisibleSize (). width * 0.8, CCDirector: shareddire()-> getVisibleSize (). height); // generally the origin m_ScrollView-> setPosition (ccp (0, 0); // the size of the view (usually the size of the screen) m_ScrollView-> setViewSize (CCDirector: shareddire()-> getVisibleSize (); this-> addChild (m_ScrollView); return true ;}

On the way to learning, I will share with you.
