与 CreatWindow 功能作斗争

Question

我是初学者，正在尝试编写我的第一款游戏。我正在关注前一段时间制作的教程。这是我的代码：

#include <windows.h>


//Callback function

LRESULT CALLBACK window_callback(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
    return DefWindowProc(hwnd, uMsg, wParam, lParam);
}



int WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd)
{
    //Create Window Class 

        WNDCLASS window_class = {};
        window_class.style = CS_HREDRAW | CS_VREDRAW;
        window_class.lpszClassName = L"Game Window Class";
        window_class.lpfnWndProc = window_callback;

    //Register Class

        RegisterClass(&window_class);
    

    //Create Window
    CreateWindow(window_class.lpszClassName, "My First Game!", WS_OVERLAPPEDWINDOW | WS_VISIBLE, CW_USEDEFAULT, CW_USEDEFAULT, 1280, 720, 0, 0, hInstance, 0);




};

当我尝试编译代码时，它返回了以下 2 个错误：

E0167   argument of type "const char *" is incompatible with parameter of type "LPCWSTR"
    
C2664   'HWND CreateWindowExW(DWORD,LPCWSTR,LPCWSTR,DWORD,int,int,int,int,HWND,HMENU,HINSTANCE,LPVOID)': cannot convert argument 3 from 'const char [15]' to 'LPCWSTR'

我做错了什么？

Answer 1

当你使用 Windows API 而不明确指定 ANSI 版本（带 A 后缀）或 Unicode 版本（带 W 后缀).

错误行：

window_class.lpszClassName = L"Game Window Class";
CreateWindow(window_class.lpszClassName, "My First Game!", WS_OVERLAPPEDWINDOW | WS_VISIBLE, CW_USEDEFAULT, CW_USEDEFAULT, 1280, 720, 0, 0, hInstance, 0);

更正的行：

window_class.lpszClassName = TEXT("Game Window Class");
CreateWindow(window_class.lpszClassName, TEXT("My First Game!"), WS_OVERLAPPEDWINDOW | WS_VISIBLE, CW_USEDEFAULT, CW_USEDEFAULT, 1280, 720, 0, 0, hInstance, 0);
