跟着cherno手搓游戏引擎【11】静态库、警告消除(渲染预热）

premake修改：

SRC下的premake

 Glad下的premake：

	files
	{

	}

	includedirs{
		"include"-- 为了glad.c直接#include <glad/glad.h>，而不用#include <include/glad/glad.h
	}
	filter "system:windows"

	filter { "system:windows", "configurations:Debug-AS" }

	cppdialect "C++17"
    staticruntime "on"

	targetdir ("bin/" .. outputdir .. "/%{prj.name}")

	filter "configurations:Release"
		runtime "Release"
		optimize "on"

    filter "configurations:Dist"
		runtime "Release"
		optimize "on"
        symbols "off"

之后点击重构

修改宏定义，把动态库的定义删除

Core.h:

#pragma once
//用于dll的宏
#ifdef YT_PLATFORM_WINDOWS
#if YT_DYNAMIC_LINK
		#ifdef YT_BUILD_DLL
		#define YOTO_API __declspec(dllexport) 
		#else
		#define YOTO_API __declspec(dllimport) 

		#endif // DEBUG
#else
		#define YOTO_API
#endif
#else
#error YOTO_ONLY_SUPPORT_WINDOWS
#endif // YOTO_PLATFORM_WINDOWS

#ifdef YT_DEBUG
#define YT_ENABLE_ASSERTS
#endif

#ifdef YT_ENABLE_ASSERTS
#define YT_CLIENT_ASSERT(x,...) {if(!(x)){YT_CLIENT_ERROR("断言错误：{0}",__VA_ARGS__);__debugbreak();}}
#define YT_CORE_ASSERT(x,...) {if(!(x)){YT_CORE_ERROR("断言错误：{0}",__VA_ARGS__);__debugbreak();}}
#else
#define YT_CLIENT_ASSERT(x,...)
#define YT_CORE_ASSERT(x,...)

#endif // YT_ENABLE_ASSERTS



#define BIT(x)(1<<x)
//绑定事件定义
#define YT_BIND_EVENT_FN(fn) std::bind(&fn, this, std::placeholders::_1)

imGui.Layer.cpp:强转float，把警告消除，实在找不到不改也没关系

io.DisplaySize = ImVec2((float)app.GetWindow().GetWidth(), (float)app.GetWindow().GetHeight());

先水一期，下一期开启渲染！
