新建vendor文件夾

將下載好的spdlog放入

配置YOTOEngine的附加包含目錄：

配置Sandbox的附加包含目錄：

包裝spdlog：

在YOTO文件夾下創(chuàng)建Log.cpp和log.h

log.h：

#pragma once
#include"Core.h"
#include<spdlog/spdlog.h>
#include "spdlog/sinks/stdout_color_sinks.h" 
namespace YOTO {class YOTO_API Log{public:static void Init();//inline是為了提高性能，相當(dāng)于直接把函數(shù)里的代碼段放在那里//返回的是Logger，分為服務(wù)器logger和核心loggerinline static  std::shared_ptr<spdlog::logger>  GetCoreLogger() { return s_CoreLogger; }inline static  std::shared_ptr<spdlog::logger>  GetClientLogger() { return s_ClientLogger; }private:static std::shared_ptr<spdlog::logger> s_CoreLogger;static std::shared_ptr<spdlog::logger>  s_ClientLogger;};
}
//Core 的log 的簡化
#define YT_CORE_ERROR(...)		::YOTO::Log::GetCoreLogger()->error(__VA_ARGS__)
#define YT_CORE_WARN(...)		::YOTO::Log::GetCoreLogger()->warn(__VA_ARGS__)
#define YT_CORE_INFO(...)		::YOTO::Log::GetCoreLogger()->info(__VA_ARGS__)
#define YT_CORE_TRACE(...)		::YOTO::Log::GetCoreLogger()->trace(__VA_ARGS__)
#define YT_CORE_FATAL(...)		::YOTO::Log::GetCoreLogger()->fatal(__VA_ARGS__)
//client 的log的簡化
#define YT_CLIENT_ERROR(...)	::YOTO::Log::GetClientLogger()->error(__VA_ARGS__)
#define YT_CLIENT_WARN(...)		::YOTO::Log::GetClientLogger()->warn(__VA_ARGS__)
#define YT_CLIENT_INFO(...)		::YOTO::Log::GetClientLogger()->info(__VA_ARGS__)
#define YT_CLIENT_TRACE(...)	::YOTO::Log::GetClientLogger()->trace(__VA_ARGS__)
#define YT_CLIENT_FATAL(...)	::YOTO::Log::GetClientLogger()->fatal(__VA_ARGS__)

?log.cpp：

#include "Log.h"namespace YOTO {std::shared_ptr<spdlog::logger> Log::s_CoreLogger;std::shared_ptr<spdlog::logger>  Log::s_ClientLogger;void  Log::Init() {//設(shè)置日志格式spdlog::set_pattern("%^[%T] %n: %v%$");//創(chuàng)建多線程logger，核心logger為YOTOs_CoreLogger = spdlog::stdout_color_mt("YOTO");//設(shè)置打印消息的級別，trace是打印所有東西（篩選器）s_CoreLogger->set_level(spdlog::level::level_enum::trace);//客戶端的為APPs_ClientLogger= spdlog::stdout_color_mt("APP");s_ClientLogger->set_level(spdlog::level::level_enum::trace);}
}

?測試：

在YOTO.h中加入#include "YOTO/Log.h"，記得重新生成，把dll加入到Sandbox（后續(xù)會使用premake簡化該流程，這里暫時(shí)手動生成）

我們在入口點(diǎn)修改代碼測試：

#pragma once#ifdef YT_PLATFORM_WINDOWS
#include "../YOTO.h"extern YOTO::Application* YOTO::CreateApplication();
void main(int argc,char** argv) {YOTO::Log::Init();YT_CORE_ERROR("測試警告信息");int test = 1;YT_CLIENT_INFO("測試info:test={0}",test);auto app = YOTO::CreateApplication();app->Run();delete app;
}
#endif

輸出：

Premake配置安裝：

點(diǎn)擊下載：https://github.com/premake/premake-core/releases/download/v5.0.0-beta2/premake-5.0.0-beta2-windows.zip

創(chuàng)建vendor文件夾：文件結(jié)構(gòu)如下

編寫premake5.lua文件：

創(chuàng)建Generate.bat文件，每次將bin和bin-int刪除然后點(diǎn)這個(gè)文件就可以自動生成。

call vendor\bin\premake\premake5.exe vs2019
PAUSE

?遇到問題不要慌：

這個(gè)問題是還沒創(chuàng)建完就啟動了，只需要等一會兒就好了。

等待10秒鐘之后：啟動！

今天就看到這里，下一集：事件系統(tǒng)【持續(xù)更新中】
