U8SDK——Cocos2dx游戏快速接入U8SDK（接入篇）

作者: U8技术团队分类: U8SDK 发布时间: 2015-08-15 13:41 67条评论

最近抽了点时间，折腾了下cocos2dx中接入U8SDK的Demo。同时，简单封装了下，使得在cocos2dx中能够快速地接入U8SDK。

先说下大体的思路。和之前说的在Unity中接入U8SDK一样，在Cocos2dx中接入U8SDK,我们也分为两步，一个Android中的部分，另一个是Coccos2dx中的部分。同时，我们希望尽可能地封装不同平台之间数据的传递，以及接口的调用。使得大部分游戏基于这个封装，都可以最快地速度来完成U8SDK的接入。

新建一个Android工程，作为U8SDK和Cocos2dx的一个中间工程（U8SDK_Cocos2dx），主要负责U8SDK的接口调用封装，参数传递和解析等。这个工程，对于所有游戏都试用。
在Cocos2dx中封装JNI调用，以及和Android中交互的数据格式等的定义和解析。同样地，这部分对于所有游戏也都适用。游戏中只需要调用这里提供的相关接口，以及实现相应的回调即可完成接入。
这篇文章，我们先来总体看看，对于一个新的Cocos2dx的开发的游戏，怎么根据我们的封装，快速完成U8SDK的抽象层的接入，从而直接打出母包，再通过一键打包工具，打出最终的多个渠道包。

首先，我们使用cocos new 新建一个Cocos2dx（我这里使用的是Cocos2dx 3.x版本）工程，名为HelloCocos。

然后，解压u8sdk_cocos2dx.zip文件到HelloCocos/Classes目录下：

紧接着，我们新建两个按钮，一个登录，一个支付。再新建一个Label，显示当前的登录状态。

    this->labelUsername = Label::createWithTTF("U8SDK", "fonts/Marker Felt.ttf", 24);


    // position the label on the center of the screen
    this->labelUsername->setPosition(Vec2(origin.x + visibleSize.width / 2,
        origin.y + visibleSize.height - this->labelUsername->getContentSize().height));

    // add the label as a child to this layer
    this->addChild(this->labelUsername, 1);

    ui::Button* btnLogin = ui::Button::create("login_normal.png", "login_selected.png");
    btnLogin->setPosition(Vec2(visibleSize.width / 2 + origin.x, visibleSize.height / 2 + origin.y + 30));
    btnLogin->addClickEventListener(CC_CALLBACK_1(HelloWorld::loginClickCallback, this));
    // add the sprite as a child to this layer
    this->addChild(btnLogin, 0);

    ui::Button* btnPay = ui::Button::create("pay_normal.png", "pay_selected.png");
    btnPay->setPosition(Vec2(visibleSize.width / 2 + origin.x, visibleSize.height / 2 + origin.y - 30));
    btnPay->addClickEventListener(CC_CALLBACK_1(HelloWorld::payClickCallback, this));
    // add the sprite as a child to this layer
    this->addChild(btnPay, 0);   
 ~~~~~~       

 
然后，我们就可以开始U8SDK的接入了。
 
1、HelloWorldScene.h中的HelloWorld类，继承U8SDKCallback抽象类，实现该类中的几个回调接口，代码 如下：

~~~~~~ 
#ifndef __HELLOWORLD_SCENE_H__
#define __HELLOWORLD_SCENE_H__

#include "cocos2d.h"
#include "ui/CocosGUI.h"
#include "u8sdk/U8SDKInterface.h"

class HelloWorld : public cocos2d::Layer,U8SDKCallback
{
private:
    cocos2d::Label* labelUsername;

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();

    void loginClickCallback(cocos2d::Ref* pSender);
    void payClickCallback(cocos2d::Ref* pSender);

    // a selector callback
    void menuCloseCallback(cocos2d::Ref* pSender);

    virtual void OnInitSuc();

    virtual void OnLoginSuc(U8LoginResult* result);

    virtual void OnSwitchLogin();

    virtual void OnLogout();

    // implement the "static create()" method manually
    CREATE_FUNC(HelloWorld);
};

#endif // __HELLOWORLD_SCENE_H__

this->labelUsername = Label::createWithTTF("U8SDK", "fonts/Marker Felt.ttf", 24);

// position the label on the center of the screen

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

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

// add the label as a child to this layer

this->addChild(this->labelUsername, 1);

ui::Button* btnLogin = ui::Button::create("login_normal.png", "login_selected.png");

btnLogin->setPosition(Vec2(visibleSize.width / 2 + origin.x, visibleSize.height / 2 + origin.y + 30));

btnLogin->addClickEventListener(CC_CALLBACK_1(HelloWorld::loginClickCallback, this));

// add the sprite as a child to this layer

this->addChild(btnLogin, 0);

ui::Button* btnPay = ui::Button::create("pay_normal.png", "pay_selected.png");

btnPay->setPosition(Vec2(visibleSize.width / 2 + origin.x, visibleSize.height / 2 + origin.y - 30));

btnPay->addClickEventListener(CC_CALLBACK_1(HelloWorld::payClickCallback, this));

// add the sprite as a child to this layer

this->addChild(btnPay, 0);

~~~~~~

然后，我们就可以开始U8SDK的接入了。

1、HelloWorldScene.h中的HelloWorld类，继承U8SDKCallback抽象类，实现该类中的几个回调接口，代码如下：

~~~~~~

#ifndef __HELLOWORLD_SCENE_H__

#define __HELLOWORLD_SCENE_H__

#include "cocos2d.h"

#include "ui/CocosGUI.h"

#include "u8sdk/U8SDKInterface.h"

class HelloWorld : public cocos2d::Layer,U8SDKCallback

{

private:

cocos2d::Label* labelUsername;

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();

void loginClickCallback(cocos2d::Ref* pSender);

void payClickCallback(cocos2d::Ref* pSender);

// a selector callback

void menuCloseCallback(cocos2d::Ref* pSender);

virtual void OnInitSuc();

virtual void OnLoginSuc(U8LoginResult* result);

virtual void OnSwitchLogin();

virtual void OnLogout();

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

CREATE_FUNC(HelloWorld);

};

#endif // __HELLOWORLD_SCENE_H__

2、HelloWorldScene.cpp中init方法的最后，我们调用U8SDK的初始化方法：

U8SDKInterface::getInstance()->initSDK(this);

同时，这里要实现第一步中添加的U8SDKCallback中的回调

void HelloWorld::OnInitSuc()
{
    CCLOG("SDK初始化成功...");
    //一般不需要做什么处理
}

void HelloWorld::OnLoginSuc(U8LoginResult* result)
{
    CCLOG("SDK登录并认证成功...%s",result->userId.c_str());
    this->labelUsername->setString(result->sdkUsername);

    if (result->isSwitchAccount)
    {
        //TODO:这里退回到登录界面，并且SDK是已经登录成功状态，不用再弹出SDK的登录界面
    }
    else
    {
        //TODO:登录认证成功，获取服务器列表，进入游戏服...
    }
}

void HelloWorld::OnSwitchLogin()
{
    CCLOG("切换帐号成功...");
    //TODO:退回到登录界面，并弹出SDK登录界面(调用U8SDKInterface::getInstance()->login())
}

void HelloWorld::OnLogout()
{
    CCLOG("SDK帐号退出成功...");
    this->labelUsername->setString("U8SDK");
    //TODO:退回到登录界面，并弹出SDK登录界面(调用U8SDKInterface::getInstance()->login())
}

void HelloWorld::OnInitSuc()

{

CCLOG("SDK初始化成功...");

//一般不需要做什么处理

}

void HelloWorld::OnLoginSuc(U8LoginResult* result)

{

CCLOG("SDK登录并认证成功...%s",result->userId.c_str());

this->labelUsername->setString(result->sdkUsername);

if (result->isSwitchAccount)

{

//TODO:这里退回到登录界面，并且SDK是已经登录成功状态，不用再弹出SDK的登录界面

}

else

{

//TODO:登录认证成功，获取服务器列表，进入游戏服...

}

void HelloWorld::OnSwitchLogin()

{

CCLOG("切换帐号成功...");

//TODO:退回到登录界面，并弹出SDK登录界面(调用U8SDKInterface::getInstance()->login())

}

void HelloWorld::OnLogout()

{

CCLOG("SDK帐号退出成功...");

this->labelUsername->setString("U8SDK");

//TODO:退回到登录界面，并弹出SDK登录界面(调用U8SDKInterface::getInstance()->login())

}

3、定义登录按钮和支付按钮的点击事件，登录点击的时候，触发登录；U8SDKInterface::getInstance()->login();支付按钮点击的时候，触发支付：U8SDKInterface::getInstance()->pay(params);完整的代码，如下：

#include "HelloWorldScene.h"

USING_NS_CC;

Scene* HelloWorld::createScene()
{
    // 'scene' is an autorelease object
    auto scene = Scene::create();

    // 'layer' is an autorelease object
    auto 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()
{
    //////////////////////////////
    // 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(HelloWorld::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

    this->labelUsername = Label::createWithTTF("U8SDK", "fonts/Marker Felt.ttf", 24);

    // position the label on the center of the screen
    this->labelUsername->setPosition(Vec2(origin.x + visibleSize.width / 2,
        origin.y + visibleSize.height - this->labelUsername->getContentSize().height));

    // add the label as a child to this layer
    this->addChild(this->labelUsername, 1);

    ui::Button* btnLogin = ui::Button::create("login_normal.png", "login_selected.png");
    btnLogin->setPosition(Vec2(visibleSize.width / 2 + origin.x, visibleSize.height / 2 + origin.y + 30));
    btnLogin->addClickEventListener(CC_CALLBACK_1(HelloWorld::loginClickCallback, this));
    // add the sprite as a child to this layer
    this->addChild(btnLogin, 0);

    ui::Button* btnPay = ui::Button::create("pay_normal.png", "pay_selected.png");
    btnPay->setPosition(Vec2(visibleSize.width / 2 + origin.x, visibleSize.height / 2 + origin.y - 30));
    btnPay->addClickEventListener(CC_CALLBACK_1(HelloWorld::payClickCallback, this));
    // add the sprite as a child to this layer
    this->addChild(btnPay, 0);

    //NDKHelper::addSelector("U8Selectors", "onU8LoginResult", CC_CALLBACK_2(HelloWorld::onU8LoginResult, this), this);
    U8SDKInterface::getInstance()->initSDK(this);

    return true;
}

void HelloWorld::OnInitSuc()
{
    CCLOG("SDK初始化成功...");
    //一般不需要做什么处理
}

void HelloWorld::OnLoginSuc(U8LoginResult* result)
{
    CCLOG("SDK登录并认证成功...%s",result->userId.c_str());
    this->labelUsername->setString(result->sdkUsername);

    if (result->isSwitchAccount)
    {
        //TODO:这里退回到登录界面，并且SDK是已经登录成功状态，不用再弹出SDK的登录界面
    }
    else
    {
        //TODO:登录认证成功，获取服务器列表，进入游戏服...
    }
}

void HelloWorld::OnSwitchLogin()
{
    CCLOG("切换帐号成功...");
    //TODO:退回到登录界面，并弹出SDK登录界面(调用U8SDKInterface::getInstance()->login())
}

void HelloWorld::OnLogout()
{

4、将HelloCocos生成proj.android导入到eclipse中，然后将U8SDK2和U8SDK_Cocos2dx工程生成的jar包（分别是u8sdk2.jar和u8sdk_cocos2dx.jar）拷贝到HelloCocos安卓工程的libs目录下。然后，将生成的 AppActivity.java，本来是继承Cocos2dxActivity的，改为继承U8CocosActivity。
同时，将AndroidManifest.xml中的application节点中，加上android:name=”com.u8.sdk.U8Application”

最后，为了能够在Android中编译并运行，我们还需要将U8SDK包含的这些Cpp文件，添加到Android.mk中，最终的文件如下：

到这里，接入就算完成了。我们可以使用cocos compile -p android 命令来编译Android平台，之前的操作如果稍有不慎，这里编译的过程中，也许会遇到一些错误，不过，看着啥错误，一一解决即可。

编译成功之后，在proj.android的bin目录下会生成一些apk文件，将HeroCocos-debug.apk拷贝到U8SDK打包工具目录下，替换原来的u8.apk
然后，运行package.bat，选择需要打包的渠道，然后就开始打包了，打包完成之后，在output目录下生成当前渠道SDK的渠道包，比如最终UC的包：
