你可以在此工程文件夹中找到Resources文件夹,你可以发现其中的内容就是早已被我们玩烂的HelloWorld.png与关闭按钮。 @H_301_0@Cocos2dx用到所有图片、音乐资源都在必须在文件夹中才能够被调用。 @H_301_0@
@H_301_0@我们再拷贝一个Windows自带的实例音乐Kalimba.mp3进去,让我们的Cocos2dx程序在启动时,自动循环播放这个Kalimba.mp3音乐,也就是游戏的BGM。 @H_301_0@直接打开proj.win32中的HelloCpp.sln。 @H_301_0@对HelloCpp或只在HelloWorld这个场景播放BGM,则对其点击属性,如下图添加Cocos2dx的音频引擎cocosDenshion所需的包。就是把.(Cocos2dx)\CososDenshion\include这个文件夹全员引入到此工程或此cpp。 @H_301_0@
@H_301_0@点击确定之后,我们只需要在HelloWorldScene.cpp中引入头文件#include "SimpleAudioEngine.h"同时在bool HelloWorld::init(){}中加入一行播放背景音乐的代码就可以了。最终HelloWorldScene.cpp的代码修改如下,其实没改什么。
#include "HelloWorldScene.h" #include "SimpleAudioEngine.h"//引入头文件 USING_NS_CC; CCScene* HelloWorld::scene() { // 'scene' is an autorelease object CCScene *scene = CCScene::create(); // 'layer' is an autorelease object HelloWorld *layer = HelloWorld::create(); // add layer as a child to scene scene->addChild(layer); // return the scene return scene; } // on "init" you need to initialize your instance bool HelloWorld::init() { CocosDenshion::SimpleAudioEngine::sharedEngine()->playBackgroundMusic("Kalimba.mp3",true);//播放音乐 //区别于CocosDenshion::SimpleAudioEngine::sharedEngine()->playEffect("xx.wav");专门用来播放简短的音效 ////////////////////////////// // 1. super init first if ( !CCLayer::init() ) { return false; } CCSize visibleSize = CCDirector::sharedDirector()->getVisibleSize(); CCPoint origin = CCDirector::sharedDirector()->getVisibleOrigin(); ///////////////////////////// // 2. add a menu item with "X" image,which is clicked to quit the program // you may modify it. // add a "close" icon to exit the progress. it's an autorelease object CCMenuItemImage *pCloseItem = CCMenuItemImage::create( "CloseNormal.png","CloseSelected.png",this,menu_selector(HelloWorld::menuCloseCallback)); pCloseItem->setPosition(ccp(origin.x + visibleSize.width - pCloseItem->getContentSize().width/2,origin.y + pCloseItem->getContentSize().height/2)); // create menu,it's an autorelease object CCMenu* pMenu = CCMenu::create(pCloseItem,NULL); pMenu->setPosition(CCPointZero); this->addChild(pMenu,1); ///////////////////////////// // 3. add your codes below... // add a label shows "Hello World" // create and initialize a label CCLabelTTF* pLabel = CCLabelTTF::create("Hello World","Arial",24); // position the label on the center of the screen pLabel->setPosition(ccp(origin.x + visibleSize.width/2,origin.y + visibleSize.height - pLabel->getContentSize().height)); // add the label as a child to this layer this->addChild(pLabel,1); // add "HelloWorld" splash screen" CCSprite* pSprite = CCSprite::create("HelloWorld.png"); // position the sprite on the center of the screen pSprite->setPosition(ccp(visibleSize.width/2 + origin.x,visibleSize.height/2 + origin.y)); // add the sprite as a child to this layer this->addChild(pSprite,0); return true; } void HelloWorld::menuCloseCallback(CCObject* pSender) { #if (CC_TARGET_PLATFORM == CC_PLATFORM_WINRT) || (CC_TARGET_PLATFORM == CC_PLATFORM_WP8) CCMessageBox("You pressed the close button. Windows Store Apps do not implement a close button.","Alert"); #else CCDirector::sharedDirector()->end(); #if (CC_TARGET_PLATFORM == CC_PLATFORM_IOS) exit(0); #endif #endif }运行此程序,就可以听到Kalimba.mp3这个难听得要死的Windows7示例音乐了。其中CocosDenshion::SimpleAudioEngine::sharedEngine()->playBackgroundMusic("Kalimba.mp3",true);中第一个参数就是此音乐在Resource文件夹的路径,true代表循环播放。 原文链接:https://www.f2er.com/cocos2dx/341695.html
