Cocos2d-x 3.0 game instance learning notes "parkour" first Interface

Cocos2d-x3.0 mobile game development C ++ instance Parkour

The starting interface is similar to that of its predecessors:Cocos2d-x game development (a) Start InterfaceBut there are also differences

The following describes all the resources used in the game.

The START interface is defined as mainscene with the following functions:

1. Background

2. Enter the game interface button

3. Pre-load the background music file

. H file

#ifndef __MainScene__H__#define __MainScene__H__#include "cocos2d.h"class MainScene : cocos2d::Layer{public:virtual bool init();static cocos2d::Scene* scene();CREATE_FUNC(MainScene);private://void createBG();//void createButton(cocos2d::Point centerPoint);//void preLoadMusic();//menu start the gamevoid start();};/**/#endif

. Cpp

#include "MainScene.h"#include "SimpleAudioEngine.h"//#include "PlayScene.h"USING_NS_CC;using namespace CocosDenshion;Scene* MainScene::scene(){Scene* scene = Scene::create();Layer* layer = MainScene::create();scene->addChild(layer);return scene;}bool MainScene::init(){if(!Layer::init()){return false;}//preloadMusicpreLoadMusic();//create backgroundcreateBG();return true;}void MainScene::createBG(){auto winSize = Director::getInstance()->getWinSize();auto centerPoint = ccp(winSize.width / 2, winSize.height / 2);//BGSprite* spriteBg = Sprite::create("MainBG.png");spriteBg->setPosition(centerPoint);this->addChild(spriteBg);//create buttoncreateButton(centerPoint);}void MainScene::createButton(cocos2d::Point centerPoint){//Start muttonMenuItemImage* menuItem = MenuItemImage::create("start_n.png","start_s.png",CC_CALLBACK_0(MainScene::start,this));Menu* menu = Menu::create(menuItem,NULL);menu->setPosition(centerPoint);this->addChild(menu);}void MainScene::preLoadMusic(){SimpleAudioEngine* audioEngin = SimpleAudioEngine::getInstance();audioEngin->preloadBackgroundMusic("background.mp3");audioEngin->preloadEffect("jump.mp3");audioEngin->preloadEffect("crouch.mp3");}void MainScene::start(){CCLOG("game is start !");//Scene* playScene = TransitionFade::create(1,PlayScene::createScene());//Director::getInstance()->replaceScene(playScene);}

I am not familiar with screen self-adaptation. Although I have read several articles, I am still confused and do not know how to use them in the instance. So in this rewriting, generally, the background image is 640*320 in size, so it must be in appdelegate. in CPP, set the display window size:

Bool appdelegate: applicationdidfinishlaunching () {// initialize Director auto Director = Director: getinstance (); Auto glview = Director-> getopenglview (); If (! Glview) {glview = glview: Create ("My Game"); glview-> setframesize (640,320); // ------ modify the display window size Director-> setopenglview (glview );} // turn on display FPS Director-> setdisplaystats (true); // set FPS. the default value is 1.0/60 if you don't call this ctor-> setanimationinterval (1.0/60); // create a scene. it's an autorelease objectauto scene = mainscene: Scene (); // run Director-> runwithscene (scene); Return true ;}

I can only learn more about it later. If you have a good tutorial, please recommend it. Thank you !!

Personal ignorance. Thank you for your correction and discussion.
