在Emscripten中处理SDL2大小调整的正确方法

#include <SDL2/SDL.h>

if (SDL_Init(SDL_INIT_VIDEO) < 0) {
    // 初始化失败的处理逻辑
}

SDL_Window* window = SDL_CreateWindow("Window Title", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, width, height, SDL_WINDOW_SHOWN);
if (window == NULL) {
    // 窗口创建失败的处理逻辑
}

SDL_Renderer* renderer = SDL_CreateRenderer(window, -1, SDL_RENDERER_ACCELERATED);
if (renderer == NULL) {
    // 渲染器创建失败的处理逻辑
}

SDL_Event event;
while (SDL_PollEvent(&event)) {
    if (event.type == SDL_WINDOWEVENT && event.window.event == SDL_WINDOWEVENT_RESIZED) {
        // 窗口大小调整的处理逻辑
        int newWidth = event.window.data1;
        int newHeight = event.window.data2;
        // 更新窗口大小
        SDL_SetWindowSize(window, newWidth, newHeight);
    }
}

SDL_RenderClear(renderer);
// 在这里进行渲染逻辑
SDL_RenderPresent(renderer);
