Cocos2d-x 3.1.1 lua-tests 开篇

Cocos2d-x 3.1.1 lua-tests开篇

  本篇博客打算从研究Cocos2d-x引擎提供的測试样例来写起，笔者针对Cocos2d-x 3.1.1这个版本号来介绍怎样来学习它给我们提供的样例，通过这些样例来深入学习Cocos2d-x核心API的使用。在学习过程中，笔者相同跟非常多刚開始学习的人一样有非常多疑惑，为了能帮助到很多其它刚開始学习的人，笔者会提出自己的疑惑然后进行解决，笔者会把每个样例都进行具体说明，对相关代码进行凝视，那么以后刚開始学习的人就能够对比笔者的博客来学习Cocos2d-x的使用，我想会事半功倍的。对笔者来说，什么版本号并不重要，重要的是学习的思路，接下来的系列博客就是笔者学习Cocos2d-x的思路。

  怎样開始呢？

  自然先到Cocos2d-x官网下载对应版本号的引擎，笔者这里是Cocos2d-x 3.1.1

  下载完毕后，希望童鞋们自己试着去搭建好开发环境，网络和笔者前面的博客均有介绍，笔者在这里就不多说了。

  最好要在win32平台、Android平台都执行成功过HelloWorld，有了这个基础之后，就能够找样例学习了。

 Cocos2d-x 3.1.1样例的代码在cocos2d-x-3.1.1 ests下：

 

这里就有我们的C++代码和Lua代码，我们要学习的是Lua项目，怎么执行这些项目呢，看下图：

双击使用Visual Studio打开，笔者这里是2012的。

  

右键设置lua-tests为启动项目，然后进行编译执行，成功之后的效果例如以下：

从这些样例，我们能够了解到Cocos2d-x全部相关API所能实现的基础效果，笔者觉得没有不论什么学习资料能比得上这些样例了。

怎么查看实现以上效果的Lua代码呢，以下笔者会给大家介绍。

笔者用到的一个开发工具是LDT,童鞋们能够到这里下载：http://www.eclipse.org/koneki/ldt/

打开LDT，切换工作空间到我们的lua-tests项目中，例如以下：

然后新建Lua项目，取名为src，这样我们就能够把当前文件夹下src全部的Lua代码都包括进来了：

这样我们就能够非常方便查看每个样例的Lua代码，查看它的具体实现。

我们的Lua项目的入口在哪里呢？

打开win32项目，找到AppDelegate.cpp，打开查看：

#include "cocos2d.h"
#include "AppDelegate.h"
#include "CCLuaEngine.h"
#include "audio/include/SimpleAudioEngine.h"
#include "lua_assetsmanager_test_sample.h"

using namespace CocosDenshion;

USING_NS_CC;

AppDelegate::AppDelegate()
{
}

AppDelegate::~AppDelegate()
{
    SimpleAudioEngine::end();
}

bool AppDelegate::applicationDidFinishLaunching()
{
	// 获得导演类实例
    auto director = Director::getInstance();
	// 获取渲染全部东西的 EGLView NA NA
    auto glview = director->getOpenGLView();
    if(!glview) {
        glview = GLView::createWithRect("Lua Tests", Rect(0,0,900,640));
        director->setOpenGLView(glview);
    }

    // turn on display FPS
	// 打开显示帧屏
    director->setDisplayStats(true);

    // set FPS. the default value is 1.0/60 if you don't call this
	// 设置游戏画面每秒显示的帧数，默认是60帧。
    director->setAnimationInterval(1.0 / 60);

	// 获得屏幕大小
    auto screenSize = glview->getFrameSize();

	// 获得设计大小
    auto designSize = Size(480, 320);

    if (screenSize.height > 320)
    {
        auto resourceSize = Size(960, 640);
        director->setContentScaleFactor(resourceSize.height/designSize.height);
    }

	// 设置屏幕设计分辨率
    glview->setDesignResolutionSize(designSize.width, designSize.height, ResolutionPolicy::FIXED_HEIGHT);

    // register lua engine
    LuaEngine* pEngine = LuaEngine::getInstance();
    ScriptEngineManager::getInstance()->setScriptEngine(pEngine);

#if (CC_TARGET_PLATFORM == CC_PLATFORM_WIN32 || CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID ||CC_TARGET_PLATFORM == CC_PLATFORM_IOS || CC_TARGET_PLATFORM == CC_PLATFORM_MAC)
    LuaStack* stack = pEngine->getLuaStack();
    register_assetsmanager_test_sample(stack->getLuaState());
#endif
	// 执行脚本语言
    pEngine->executeScriptFile("src/controller.lua");

    return true;
}

// This function will be called when the app is inactive. When comes a phone call,it's be invoked too
void AppDelegate::applicationDidEnterBackground()
{
    Director::getInstance()->stopAnimation();

    SimpleAudioEngine::getInstance()->pauseBackgroundMusic();
}

// this function will be called when the app is active again
void AppDelegate::applicationWillEnterForeground()
{
    Director::getInstance()->startAnimation();

    SimpleAudioEngine::getInstance()->resumeBackgroundMusic();
}

我们会发现代码中这么一段：

pEngine->executeScriptFile("src/controller.lua");

这个就是我们的入口文件，我们执行Lua的代码是从controller.lua这个文件開始的。

我们用LDT查看一下它的代码：

-- 避免内存泄漏
collectgarbage("setpause", 100) 
collectgarbage("setstepmul", 5000)

-- 创建场景
local scene = cc.Scene:create()
-- 加入菜单
scene:addChild(CreateTestMenu())
if cc.Director:getInstance():getRunningScene() then
    cc.Director:getInstance():replaceScene(scene)
else
    -- 依据给定的场景进入 Director的主循环 仅仅能调用他执行你的第一个场景.
    cc.Director:getInstance():runWithScene(scene)
end

然后我们就能够依据这个，来理清整个測试项目的脉路，我们或许想知道，样例中的那些菜单是怎么显示出来的，样例中又是怎样进行切换场景的。仅仅要我们知道怎样開始了，以后我们就能够慢慢分析每个样例所给我提供的代码。

在controller.lua文件里引入了maniMenu.lua

通过这个语句：require "src/mainMenu"

这个文件定义了全部的资源路径，一些图片、json资源、字体资源等。

其它相关的文件，笔者在这里就不贴代码，这个大家私下去查看，我在这里仅仅是提供相关的思路，让大家理清怎样使用Cocos2d-x给我们提供的样例进行学习。

下一篇博客，笔者将会介绍第一个样例-重力加速器，非常感谢你的关注。
