从0开发游戏引擎之引擎Win32平台的Platform类实现
2024-05-25 01:22:06
这个引擎是基于win32架构写的， Platform可以理解成是整个引擎的入口。控制着引擎的整个生命周期，内部主要完成了openGL、win32窗口句柄的初始化；键盘鼠标事件分发；主循环控制。关闭程序的处理。
1.首先是执行了Platform中的静态函数SetWindowSize，设置了Win32窗口的初始化xy位置，以及窗口大小。
void CPlateForm::setWindowSize(int x, int y, int wid, int hei)
{window_x = x;window_y = y;windows_width = wid;windows_height = hei;
}2.接着是构造Platform的单例类（当时代码有些不规范，Platform已经是单例类了，直接在Init的时候传递x、y、w、h，然后在Init函数里执行原本构造函数里的这些代码就好了。没有必要再写一个静态类专门来Save一下x、y、w、h这四个参数了）
CPlateForm::CPlateForm()
{hRC = NULL;hDC = NULL;hWnd = NULL;hInst = NULL;isPause = false;gameMode = PLAYING;ShowWindow(hWnd, SW_SHOWDEFAULT);UpdateWindow(hWnd);MyRegisterClass();// 执行应用程序初始化: if (!InitInstance()){MessageBox(NULL, L"不能成功初始化", L"错误", MB_OK | MB_ICONEXCLAMATION);}HACCEL hAccelTable = LoadAccelerators(hInst, MAKEINTRESOURCE(NULL));memset(&msg, 0, sizeof(MSG));m_Audio.Initialize(hWnd);
}2.1.接着会调用MyRegisterClass对Win32窗口的大小、icon、光标、窗口风格进行设置，然后调用系统API把我们设置好的参数传递给操作系统。
ATOM CPlateForm::MyRegisterClass()
{WNDCLASSEXW wcex;wcex.cbSize = sizeof(WNDCLASSEX);wcex.style = CS_HREDRAW | CS_VREDRAW;wcex.lpfnWndProc = WndProc;wcex.cbClsExtra = 0;wcex.cbWndExtra = 0;wcex.hInstance = hInst;wcex.hIcon = LoadIcon(hInst,NULL);//托盘上的ICO图标wcex.hCursor = LoadCursorFromFileA("res/color/0081.ani");wcex.hbrBackground = (HBRUSH)(COLOR_WINDOW + 1);wcex.lpszMenuName = NULL;wcex.lpszClassName = L"myClass";wcex.hIconSm = LoadIcon(wcex.hInstance,NULL);//窗口上的ICO图标return RegisterClassExW(&wcex);
}2.2 配置完成窗口配置后，会在这个函数里真正的创建一个Win32窗口，并返回一个窗口句柄（其实可以理解成系统给我们分配的一个窗口Id），接着初始化OpenGL。
BOOL CPlateForm::InitInstance()
{//hInst = hInstance; // 将实例句柄存储在全局变量中int nX = GetSystemMetrics(SM_CXFRAME) * 4;int nY = GetSystemMetrics(SM_CYFRAME) * 4 + GetSystemMetrics(SM_CYCAPTION);//+ GetSystemMetrics(SM_CYMENU);//创建Win32窗口，返回窗口句柄hWnd = CreateWindowW(L"myClass", L"荒岛求生_V1.1", WS_OVERLAPPEDWINDOW,window_x, window_y, windows_width + nX, windows_height + nY, nullptr, nullptr, NULL, nullptr);if (!hWnd){return FALSE;}//初始化OpenGL配置InitGL();//初始化硬件获取纹理通道glewInit();//操作系统API，显示这个窗口ShowWindow(hWnd, true);//立即刷新窗口UpdateWindow(hWnd);//顶点缓存上的，没有用到//使用VBO查询字符串为
//#ifndef NO_VBOS
// g_fVBOSupported = IsExtensionSupported("GL_ARB_vertex_buffer_object");
// //返回1为支持.
// //下面声明VBO扩展函数
// // VBO Extension Function Pointers
// PFNGLGENBUFFERSARBPROC glGenBuffersARB = NULL; // VBO Name Generation Procedure
// PFNGLBINDBUFFERARBPROC glBindBufferARB = NULL; // VBO Bind Procedure
// PFNGLBUFFERDATAARBPROC glBufferDataARB = NULL; // VBO Data Loading Procedure
// PFNGLDELETEBUFFERSARBPROC glDeleteBuffersARB = NULL; // VBO Deletion Procedure
//
// if (g_fVBOSupported) //获取函数地址
// {
// // 获得函数的指针
// glGenBuffersARB = (PFNGLGENBUFFERSARBPROC)wglGetProcAddress("glGenBuffersARB");
// glBindBufferARB = (PFNGLBINDBUFFERARBPROC)wglGetProcAddress("glBindBufferARB");
// glBufferDataARB = (PFNGLBUFFERDATAARBPROC)wglGetProcAddress("glBufferDataARB");
// glDeleteBuffersARB = (PFNGLDELETEBUFFERSARBPROC)wglGetProcAddress("glDeleteBuffersARB");
// }
//#else
// g_fVBOSupported = false;
//#endifreturn TRUE;
}2.3 这个函数比较长，其实主要干的事儿就是给OpenGL传递参数开启或者关闭开关，对OpenGL进行初始化，因为OpenGL需要设置的参数实在是太多了，具体备注代码上都有，大家直接看代码吧！
// 此处开始对OpenGL进行所有设置
GLboolean CPlateForm::InitGL(GLvoid)
{static PIXELFORMATDESCRIPTOR pfd = // /pfd 告诉窗口我们所希望的东东，即窗口使用的像素格式{sizeof(PIXELFORMATDESCRIPTOR), // 上述格式描述符的大小1, // 版本号PFD_DRAW_TO_WINDOW | // 格式支持窗口PFD_SUPPORT_OPENGL | // 格式必须支持OpenGLPFD_DOUBLEBUFFER, // 必须支持双缓冲PFD_TYPE_RGBA, // 申请 RGBA 格式24, // 选定色彩深度0, 0, 0, 0, 0, 0, // 忽略的色彩位0, // 无Alpha缓存0, // 忽略Shift Bit0, // 无累加缓存0, 0, 0, 0, // 忽略聚集位16, // 16位 Z-缓存 (深度缓存)1, // 无蒙板缓存0, // 无辅助缓存PFD_MAIN_PLANE, // 主绘图层0, // Reserved0, 0, 0 // 忽略层遮罩};if (!(hDC = GetDC(hWnd))) // 取得设备描述表了么?{KillGLWindow(); // 重置显示区MessageBox(NULL, L"不能创建一种相匹配的像素格式", L"错误", MB_OK | MB_ICONEXCLAMATION);return FALSE;// 返回 FALSE}GLuint PixelFormat = ChoosePixelFormat(hDC, &pfd); // Windows 找到相应的象素格式了吗?if (!SetPixelFormat(hDC, PixelFormat, &pfd)) // 能够设置象素格式么?return false;// 能否取得着色描述表?if (!(hRC = wglCreateContext(hDC))) return false;// 尝试激活着色描述表if (!wglMakeCurrent(hDC, hRC)) return false;// Windows 找到相应的象素格式了吗?if (!(PixelFormat = ChoosePixelFormat(hDC, &pfd))) {KillGLWindow(); // 重置显示区MessageBox(NULL, L"不能设置像素格式", L"错误", MB_OK | MB_ICONEXCLAMATION);return FALSE; // 返回 FALSE}if (!SetPixelFormat(hDC, PixelFormat, &pfd)) // 能够设置象素格式么?{KillGLWindow(); // 重置显示区MessageBox(NULL, L"不能设置像素格式", L"错误", MB_OK | MB_ICONEXCLAMATION);return FALSE; // 返回 FALSE}if (!(hRC = wglCreateContext(hDC))) // 能否取得着色描述表?{KillGLWindow(); // 重置显示区MessageBox(NULL, L"不能创建OpenGL渲染描述表", L"错误", MB_OK | MB_ICONEXCLAMATION);return FALSE; // 返回 FALSE}if (!wglMakeCurrent(hDC, hRC)) // 尝试激活着色描述表{KillGLWindow(); // 重置显示区MessageBox(NULL, L"不能激活当前的OpenGL渲然描述表", L"错误", MB_OK | MB_ICONEXCLAMATION);return FALSE; // 返回 FALSE}glStencilMask(0); //蒙版缓冲区置为0glShadeModel(GL_SMOOTH); // 启用阴影平滑glClearColor(0.0f,0.0f, 0.0f,1.0f); // 背景glClearDepth(1.0f); // 设置深度缓存glEnable(GL_DEPTH_TEST); // 启用深度测试glDepthFunc(GL_LEQUAL); // 所作深度测试的类型glHint(GL_PERSPECTIVE_CORRECTION_HINT, GL_NICEST); // 真正精细的透视修正,告诉系统对透视进行修正glFrontFace(GL_CCW); //多边形逆时针方向为正面glClearStencil(0); glEnable(GL_CULL_FACE); //只显示正面ReSizeGLScene(windows_width, windows_height); //设置openGL窗口大小InitGeometry();return TRUE; // 初始化 OK
}2.4 InitGeometry 是初始化操作的最后一个函数，函数里面干的事儿主要就是设置光源位置，设置环境光、漫反射、高光的颜色。开启了范围雾、设置了雾的开始Z值 和 结束Z值，其实这些代码也能放到InitGL函数里面，但是考虑到InitGL函数太长了，这些代码干的事儿主要是初始化光源和雾气配置，所以细分了一下函数，就给拆出来了。
void CPlateForm::InitGeometry()
{glEnable(GL_NORMALIZE);GLfloat LightPos[] = { 0.0f,0.0f,5.0f,1.0f };GLfloat LightAmb[] = { 0.5f,0.5f,0.5f,1.0f };GLfloat LightDif[] = { 0.8f,0.8f,0.8f,1.0f };GLfloat LightSpe[] = { 0.8f,0.8f,0.8f,1.0f };glLightfv(GL_LIGHT0, GL_POSITION, LightPos);glLightfv(GL_LIGHT0, GL_AMBIENT, LightAmb);glLightfv(GL_LIGHT0, GL_DIFFUSE, LightDif);glLightfv(GL_LIGHT0, GL_SPECULAR, LightSpe);GLuint fogMode[] = { GL_EXP, GL_EXP2, GL_LINEAR }; // 雾气的模式GLfloat fogColor[4] = { 0.5f, 0.5f, 0.5f, 1.0f }; // 雾的颜色设为灰色glFogi(GL_FOG_MODE, GL_LINEAR); // 设置雾气的模式glFogfv(GL_FOG_COLOR, fogColor); // 设置雾的颜色glFogf(GL_FOG_DENSITY,0.05f); // 设置雾的密度glHint(GL_FOG_HINT, GL_DONT_CARE); // 设置系统如何计算雾气glFogf(GL_FOG_START,2000.0f); // 雾气的开始位置glFogf(GL_FOG_END,4000.0f); // 雾气的结束位置
}3.Run起来！初始化都完成之后，程序当然就要Run起来了，这个引擎其实只能说是一个Demo引擎，逻辑线程和渲染线程当时给放到一块儿了，Render函数里其实不光是做了DrawElement这件事儿，而且还做了逻辑的update这件事儿，所以现在要我做的话肯定要分两个线程来做，而且Render里面的Update函数也得拆出来。每次循环都会Clear颜色缓冲区和深度缓冲区，清理了前台缓冲区后，立马使用SwapBuffers把后台的缓冲区交换到前台来，这样可以保证画面不会出现闪屏的现象。

}ps：刚毕业的时候对工程的理解不深刻，代码里有很多不规范的地方，比如把游戏的具体逻辑给写道了引擎里去了，这些当时想拆出来的，但是后来工作一忙还没有拆干净也就不了了之了。
ps2:本来想从具体的引擎模块开始写起的，但是发现还是从主入口写会更好理解吧，所以就从平台类开始写了。准备文章写完后就把整个工程传到gitee上去，供大家学习。也可以一起修改，有任何问题都可以加q群716872510大家可以一起交流吹b！
