vs2013生成lib

Posted 2020-09-27 mthoutai

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

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

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

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
