在2d游戏中控制玩家的更好方法是什么？(sdl2)

// 示例代码：SDL2键盘输入处理
#include <SDL2/SDL.h>

int main(int argc, char* argv[]) {
    SDL_Init(SDL_INIT_VIDEO);
    SDL_Window* window = SDL_CreateWindow("2D Game", SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED, 800, 600, SDL_WINDOW_SHOWN);
    SDL_Renderer* renderer = SDL_CreateRenderer(window, -1, SDL_RENDERER_ACCELERATED);

    bool running = true;
    SDL_Event event;

    while (running) {
        while (SDL_PollEvent(&event)) {
            if (event.type == SDL_QUIT) {
                running = false;
            }
            if (event.type == SDL_KEYDOWN) {
                switch (event.key.keysym.sym) {
                    case SDLK_ESCAPE:
                        running = false;
                        break;
                    case SDLK_UP:
                        // 处理向上移动
                        break;
                    case SDLK_DOWN:
                        // 处理向下移动
                        break;
                    case SDLK_LEFT:
                        // 处理向左移动
                        break;
                    case SDLK_RIGHT:
                        // 处理向右移动
                        break;
                }
            }
        }

        SDL_RenderClear(renderer);
        // 渲染游戏画面
        SDL_RenderPresent(renderer);
    }

    SDL_DestroyRenderer(renderer);
    SDL_DestroyWindow(window);
    SDL_Quit();

    return 0;
