谷歌小恐龙c++代码

以下是谷歌小恐龙的简单实现代码（使用C++和SDL库）：

#include <iostream>
#include <SDL.h>

using namespace std;

const int SCREEN_WIDTH = 600;
const int SCREEN_HEIGHT = 200;
const int GROUND_HEIGHT = 180;

int main(int argc, char* args[])
{
    SDL_Init(SDL_INIT_VIDEO);
    SDL_Window* window = SDL_CreateWindow("Google Dino", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, SCREEN_WIDTH, SCREEN_HEIGHT, SDL_WINDOW_SHOWN);
    SDL_Renderer* renderer = SDL_CreateRenderer(window, -1, SDL_RENDERER_ACCELERATED);

    SDL_Texture* dinoTexture = SDL_CreateTextureFromSurface(renderer, SDL_LoadBMP("dino.bmp"));
    SDL_Texture* cactusTexture = SDL_CreateTextureFromSurface(renderer, SDL_LoadBMP("cactus.bmp"));
    SDL_Texture* groundTexture = SDL_CreateTextureFromSurface(renderer, SDL_LoadBMP("ground.bmp"));

    bool quit = false;
    SDL_Event e;

    int dinoX = 0;
    int dinoY = GROUND_HEIGHT;
    int cactusX = SCREEN_WIDTH;
    int cactusY = GROUND_HEIGHT - 20;
    int groundX = 0;
    int groundY = GROUND_HEIGHT + 20;

    int dinoVelY = 0;

    while (!quit)
    {
        while (SDL_PollEvent(&e) != 0)
        {
            if (e.type == SDL_QUIT)
            {
                quit = true;
            }
            else if (e.type == SDL_KEYDOWN)
            {
                if (e.key.keysym.sym == SDLK_SPACE)
                {
                    if (dinoY == GROUND_HEIGHT)
                    {
                        dinoVelY = -10;
                    }
                }
            }
        }

        dinoY += dinoVelY;
        if (dinoY > GROUND_HEIGHT)
        {
            dinoY = GROUND_HEIGHT;
            dinoVelY = 0;
        }
        else if (dinoY < 0)
        {
            dinoY = 0;
            dinoVelY = 0;
        }

        cactusX -= 5;
        if (cactusX < -20)
        {
            cactusX = SCREEN_WIDTH;
        }

        groundX -= 5;
        if (groundX < -SCREEN_WIDTH)
        {
            groundX = 0;
        }

        SDL_SetRenderDrawColor(renderer, 255, 255, 255, 255);
        SDL_RenderClear(renderer);

        SDL_Rect dinoRect = { dinoX, dinoY, 48, 48 };
        SDL_RenderCopy(renderer, dinoTexture, NULL, &dinoRect);

        SDL_Rect cactusRect = { cactusX, cactusY, 20, 40 };
        SDL_RenderCopy(renderer, cactusTexture, NULL, &cactusRect);

        SDL_Rect groundRect1 = { groundX, groundY, SCREEN_WIDTH, 20 };
        SDL_RenderCopy(renderer, groundTexture, NULL, &groundRect1);

        SDL_Rect groundRect2 = { groundX + SCREEN_WIDTH, groundY, SCREEN_WIDTH, 20 };
        SDL_RenderCopy(renderer, groundTexture, NULL, &groundRect2);

        SDL_RenderPresent(renderer);

        SDL_Delay(17);
    }

    SDL_DestroyTexture(dinoTexture);
    SDL_DestroyTexture(cactusTexture);
    SDL_DestroyTexture(groundTexture);

    SDL_DestroyRenderer(renderer);
    SDL_DestroyWindow(window);

    SDL_Quit();

    return 0;
}

这只是一个简单的实现，你可以根据需要进行修改和扩展。
