引擎cocos2d-x-3.1.1

一、 cocos创建一个项目。随便是lua还是cpp。这里用cpp演示

二、创建完毕之后执行下项目

之后创建两个类。例如以下

TestLib.cpp文件

#include "TestLib.h"

#include "People.h"

Scene* TestLib::createScene()

{

    // 'scene' is an autorelease object

    auto scene = Scene::create();

    // 'layer' is an autorelease object

	auto layer = TestLib::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 TestLib::init()

{

    //////////////////////////////

    // 1. super init first

    if ( !Layer::init() )

    {

        return false;

    }

    Size visibleSize = Director::getInstance()->getVisibleSize();

    Vec2 origin = Director::getInstance()->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

    auto closeItem = MenuItemImage::create(

                                           "CloseNormal.png",

                                           "CloseSelected.png",

										   CC_CALLBACK_1(TestLib::menuCloseCallback, this));

	closeItem->setPosition(Vec2(origin.x + visibleSize.width - closeItem->getContentSize().width/2 ,

                                origin.y + closeItem->getContentSize().height/2));

    // create menu, it's an autorelease object

    auto menu = Menu::create(closeItem, NULL);

    menu->setPosition(Vec2::ZERO);

    this->addChild(menu, 1);

    /////////////////////////////

    // 3. add your codes below...

    // add a label shows "Hello World"

    // create and initialize a label

	lab_ = LabelTTF::create("Hello World", "Arial", 24);

    // position the label on the center of the screen

	lab_->setPosition(Vec2(origin.x + visibleSize.width / 2,

		origin.y + visibleSize.height - lab_->getContentSize().height));

    // add the label as a child to this layer

	this->addChild(lab_, 1);

    // add "HelloWorld" splash screen"

    auto sprite = Sprite::create("HelloWorld.png");

    // position the sprite on the center of the screen

    sprite->setPosition(Vec2(visibleSize.width/2 + origin.x, visibleSize.height/2 + origin.y));

    // add the sprite as a child to this layer

    this->addChild(sprite, 0);

    return true;

}

void TestLib::menuCloseCallback(Ref* pSender)

{

	/*

#if (CC_TARGET_PLATFORM == CC_PLATFORM_WP8) || (CC_TARGET_PLATFORM == CC_PLATFORM_WINRT)

	MessageBox("You pressed the close button. Windows Store Apps do not implement a close button.","Alert");

    return;

#endif

    Director::getInstance()->end();

#if (CC_TARGET_PLATFORM == CC_PLATFORM_IOS)

    exit(0);

#endif

	*/

	lab_->setString("using test lib");

	People* sp = People::create();

	sp->setPosition(ccp(200, 300));

	this->addChild(sp);

}

TestLib.h文件

#ifndef __TestLib_H__

#define __TestLib_H__

#include "cocos2d.h"

USING_NS_CC;

class TestLib : public cocos2d::Layer

{

public:

    // there's no 'id' in cpp, so we recommend returning the class instance pointer

    static cocos2d::Scene* createScene();

    // Here's a difference. Method 'init' in cocos2d-x returns bool, instead of returning 'id' in cocos2d-iphone

    virtual bool init();  

    // a selector callback

    void menuCloseCallback(cocos2d::Ref* pSender);

    // implement the "static create()" method manually

	CREATE_FUNC(TestLib);

	LabelTTF* lab_;

};

#endif // __HELLOWORLD_SCENE_H__

people.cpp文件

#include "People.h"

People::People()

{

}

People::~People()

{

}

bool People::init()

{

	if (!Node::init())

	{

		return false;

	}

	Sprite* sp = Sprite::create("CloseNormal.png");

	addChild(sp);

	return true;

}

people.h文件

#ifndef __People_H__

#define __People_H__

#include "cocos2d.h"

USING_NS_CC;

class People : public cocos2d::Node

{

public:

	People();

	~People();

    virtual bool init();  

	CREATE_FUNC(People);

};

#endif // __HELLOWORLD_SCENE_H__

三、 两个试验类已经创建完毕。这个时候执行下程序。

而且改动AppDelegate，原先是引到helloworld，改成引到testlib。程序执行通过就成，是为了保证试验类没有错误。

四、改动project配置。

1 打开project属性

watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvZGF5ZGF5dXBfY2hm/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="">

2 找到配置属性-》常规-》配置类型    改成静态库

3  选择完毕后点-》应用-》确定。之后就是生成lib

4 生成的文件在  testCpp\proj.win32\Debug.win32该文件夹下

watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvZGF5ZGF5dXBfY2hm/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="">

5 新建还有一个cppproject，这两个加上testlib.h和people.h。一共四个文件拷贝到新project的class文件夹下

使用lib库有两个方法，一个是直接把lib引到project文件夹下，在须要用到的地方include一下就能够。

代码是：#pragma comment(lib, "testCpp.lib")

另外一个方法是直接设置库路径，就不用把lib引到project文件夹下了。直接点开project属性，在配置属性-》连接器-》常规-》附加库文件夹中加入库

watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvZGF5ZGF5dXBfY2hm/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="">

之后确认。

在配置属性-》连接器-》输入-》附加依赖项。如图填写

之后确定。执行project就能够了

说明   .obj的文件不须要像lib一样。

直接加入到project文件夹下直接用就能够
