【Cocos2d-X遊戲實戰開發】捕魚達人之遊戲情境的建立（六）

本系列學習教程使用的是cocos2d-x-2.1.4（最新版為cocos2d-x-2.1.5）   

博主發現前兩個系列的學習教程被嚴重抄襲，在這裡呼籲大家請尊重開發人員的勞動成果，

一、類的建立

 

 

 

 

 

 

類中添加代碼，.h標頭檔。

#ifndef __GAME_SCENE_H__#define __GAME_SCENE_H__#include "cocos2d.h"class GameLayer :public cocos2d::CCLayer{public://初始化方法virtual bool init();//建立情境static cocos2d::CCScene* scene();CREATE_FUNC(GameLayer);//初始化組件bool setupViews();};#endif

 

.cpp檔案，這段代碼有很詳細的注釋。

#include "GameScene.h"#include "StaticData.h"USING_NS_CC;//建立遊戲情境CCScene* GameLayer::scene(){CCScene* scene = CCScene::create();GameLayer* layer = GameLayer::create();scene->addChild(layer);return scene;}//初始化方法bool GameLayer::init(){bool isRet = false;do {CC_BREAK_IF(!this->setupViews());isRet = true;} while (0);return true;}// 初始化控制項和布景bool GameLayer::setupViews(){bool isRet = false;do {CCLOG("games initialization...");//獲得視窗尺寸大小CCSize winSize = CCDirector::sharedDirector()->getWinSize();//建立背景圖片精靈CCSprite* background = CCSprite::create(STATIC_DATA_STRING("game_background"));//設定精靈位置background->setPosition(CCPointMake(winSize.width * 0.5, winSize.height * 0.5));//添加精靈至圖層this->addChild(background);//加入plist檔案至緩衝CCSpriteFrameCache::sharedSpriteFrameCache()->addSpriteFramesWithFile(STATIC_DATA_STRING("GameLayer_plist"));//從緩衝讀取並建立精靈CCSprite* game_box01 = CCSprite::createWithSpriteFrameName(STATIC_DATA_STRING("game_ui_box_01"));//設定錨點game_box01->setAnchorPoint(ccp(0.5,1));//設定精靈位置game_box01->setPosition(CCPointMake(winSize.width * 0.5, winSize.height));//添加精靈至圖層this->addChild(game_box01);//從緩衝讀取並建立精靈CCSprite* game_box02 = CCSprite::createWithSpriteFrameName(STATIC_DATA_STRING("game_ui_box_02"));//設定錨點game_box02->setAnchorPoint(ccp(0.5,0));//設定精靈位置game_box02->setPosition(CCPointMake(winSize.width * 0.5, 0));//添加精靈至圖層this->addChild(game_box02,3);//建立背景圖片精靈CCSprite* ui_2p = CCSprite::create(STATIC_DATA_STRING("game_ui_2p"));//設定精靈位置ui_2p->setPosition(CCPointMake(winSize.width * 0.5, 41));//添加精靈至圖層this->addChild(ui_2p,2);isRet=true;} while (0);return isRet;}
