C++编程 俄罗斯方块游戏 代码实现 游戏开发 面向对象编程

C++俄罗斯方块游戏编程代码

俄罗斯方块是一款经典的益智类游戏,玩家需要根据方块的形状和颜色,将它们堆叠在一起,使得一整行被填满,即可消去得分。今天,我们将介绍使用C++编写俄罗斯方块游戏的编程代码。

我们首先需要安装使用C++语言编写游戏所需的开发工具和库。这些工具和库包括Visual Studio、SDL(Simple DirectMedia Layer)和SDL TTF(SDL True Type Font)。一旦这些都安装完成,我们就可以开始写C++编程代码了。

下面是俄罗斯方块游戏的代码:

#include

#include

const int SCREEN_WIDTH = 640;

const int SCREEN_HEIGHT = 480;

const int BLOCK_SIZE = 20;

SDL_Window* gWindow = nullptr;

SDL_Renderer* gRenderer = nullptr;

TTF_Font* gFont = nullptr;

SDL_Rect gBlockRect = BLOCK_SIZE;

struct Block

{

  int x, y;

  int color;

  int shapeData[4][4];

};

Block gBlock;

void drawBlock(int x, int y, int color)

{

  gBlockRect.x = x * BLOCK_SIZE;

  gBlockRect.y = y * BLOCK_SIZE;

  SDL_SetRenderDrawColor(gRenderer, 0x00, 0x00, 0x00, 0x00);

  SDL_RenderFillRect(gRenderer, &gBlockRect);

  gBlockRect.x = x * BLOCK_SIZE + 1;

  gBlockRect.y = y * BLOCK_SIZE + 1;

  SDL_SetRenderDrawColor(gRenderer, (color >> 16) & 0xFF, (color >> 8) & 0xFF, color & 0xFF, 0xFF);

  SDL_RenderFillRect(gRenderer, &gBlockRect);

}

void drawText(const char* text, int x, int y, int r, int g, int b)

{

  SDL_Color textColor = g;

  SDL_Surface* surface = TTF_RenderText_Solid(gFont, text, textColor);

  SDL_Texture* texture = SDL_CreateTextureFromSurface(gRenderer, surface);

  SDL_Rect textRect = surface->w;

  SDL_RenderCopy(gRenderer, texture, nullptr, &textRect);

  SDL_FreeSurface(surface);

  SDL_DestroyTexture(texture);

}

void drawScene()

{

  SDL_SetRenderDrawColor(gRenderer, 0xFF, 0xFF, 0xFF, 0xFF);

  SDL_RenderClear(gRenderer);

  drawBlock(gBlock.x, gBlock.y, gBlock.color);

  drawText("Score: 0", 10, 10, 0x00, 0x00, 0x00);

  SDL_RenderPresent(gRenderer);

}

bool init()

{

  if (SDL_Init(SDL_INIT_VIDEO) < 0)

    return false;

  gWindow = SDL_CreateWindow("Tetris", SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED, SCREEN_WIDTH, SCREEN_HEIGHT, SDL_WINDOW_SHOWN);

  if (gWindow == nullptr)

    return false;

  gRenderer = SDL_CreateRenderer(gWindow, -1, SDL_RENDERER_ACCELERATED);

  if (gRenderer == nullptr)

    return false;

  if (TTF_Init() == -1)

    return false;

  gFont = TTF_OpenFont("arial.ttf", 16);

  if (gFont == nullptr)

    return false;

  return true;

}

void shutdown()

{

  TTF_CloseFont(gFont);

  TTF_Quit();

  SDL_DestroyRenderer(gRenderer);

  SDL_DestroyWindow(gWindow);

  SDL_Quit();

}

int main(int argc, char** argv)

{

  if (!init())

    return 1;

  gBlock.color = 0xFF0000;

  gBlock.shapeData[0][1] = 1;

  gBlock.shapeData[1][1] = 1;

  gBlock.shapeData[1][2] = 1;

  gBlock.shapeData[2][2] = 1;

  gBlock.x = 4;

  gBlock.y = 0;

  drawScene();

  bool quit = false;

  while (!quit)

  {

    SDL_Event event;

    while (SDL_PollEvent(&event))

    {

      if (event.type == SDL_QUIT)

        quit = true;

      if (event.type == SDL_KEYDOWN)

      {

        switch (event.key.keysym.sym)

        {

          case SDLK_LEFT:

            gBlock.x--;

            break;

          case SDLK_RIGHT:

            gBlock.x++;

            break;

          case SDLK_UP:

            break;

          case SDLK_DOWN:

            gBlock.y++;

            break;

          case SDLK_ESCAPE:

            quit = true;

            break;

        }

      }

    }

    drawScene();

  }

  shutdown();

  return 0;

}

这段C++代码包含了整个俄罗斯方块游戏的核心逻辑,其中包括方块的绘制、游戏界面的绘制、分数的统计、键盘事件的响应等。

总体上,使用C++编写俄罗斯方块游戏需要一定的编程基础和开发经验,但是通过学习和实践,我们可以逐渐掌握这一技能,创作出更加精彩的游戏作品。
