（一）初始化窗口

游戏最短流程:
1,初始化
2，循环
3，清理

代码如下
myapplication.h

#pragma once

#include <glm/vec4.hpp>
#include <glm/mat4x4.hpp>
#include <vulkan/vulkan.h>
#include
#include “D:/install/filament-v1.18.0/third_party/imgui/examples/libs/glfw/include/GLFW/glfw3.h”
#include
#include
#include
#include

class MyApplication
{
public:
void run();

private:
//初始化窗口
void initWindow();
//初始化Vulkan对象
void initVulkan();
//主循环进行渲染操作
void mainLoop();
//资源清理
void cleanUp();

private:
//窗口
GLFWwindow* window = nullptr;
};
myapplication.cpp
#include “MyApplication.h”

void MyApplication::run()
{
initWindow();
initVulkan();
mainLoop();
cleanUp();
}

void MyApplication::initWindow()
{

//初始化GLFW库，
glfwInit();
//阻止创建OpenGL上下文
glfwWindowHint(GLFW_CLIENT_API, GLFW_NO_API);
//禁止窗口大小改变
glfwWindowHint(GLFW_RESIZABLE, GLFW_FALSE);
//存储窗口句柄
const int WIDTH = 800;
const int HEIGHT = 600;
window = glfwCreateWindow(WIDTH, HEIGHT, "Vulkan window", nullptr, nullptr);

}

void MyApplication::initVulkan()
{
}

void MyApplication::mainLoop()
{
//在没有错误和窗口没有被关闭下一直运行，事件循环
while (!glfwWindowShouldClose(window))
{
glfwPollEvents();
}
}

void MyApplication::cleanUp()
{

glfwDestroyWindow(window);
glfwTerminate();

}
调用
main.cpp
#define GLFW_INCLUDE_VULKAN
#define GLM_FORCE_RADIANS
#define GLM_FORCE_DEPTH_ZERO_TO_ONE
#include “MyApplication.h”

int main()
{
MyApplication app;
app.run();
return 0;
}

运行结果如下：
