C语言项目小游戏之俄罗斯方块

**俄罗斯方块游戏**

###介绍俄罗斯方块是一款经典的益智游戏，玩家需要将形状不同的方块填满一个矩形区域。这个项目是使用C语言开发的一款简单版俄罗斯方块游戏。

### 游戏规则* 玩家可以左右移动方块。
* 当方块与已有的方块重叠时，玩家可以旋转方块。
* 当方块完全填满一个行时，该行会消失。
* 每当行数增加一行，游戏难度也会增加。

###代码实现#### **俄罗斯方块结构**

c// 定义俄罗斯方块的形状和颜色typedef struct {
 int x, y; // 方块的位置 int color; // 方块的颜色} Block;

// 定义俄罗斯方块游戏的状态typedef struct {
 int rows, cols; // 游戏区域的行数和列数 int score; // 玩家的分数 int level; // 游戏难度等级 Block blocks[10][10]; //俄罗斯方块的位置信息} Game;

// 定义俄罗斯方块游戏的函数void initGame(Game *game);
void drawGame(Game game);
void moveBlock(Game *game, int dx, int dy);
void rotateBlock(Game *game, int x, int y);
int checkCollision(Game game, int x, int y);

c// 初始化游戏状态void initGame(Game *game) {
 // 设置游戏区域的行数和列数 game->rows =20;
 game->cols =10;

 // 设置玩家的分数和难度等级 game->score =0;
 game->level =1;

 // 初始化方块位置信息 for (int i =0; i < 10; i++) {
 for (int j =0; j < 10; j++) {
 game->blocks[i][j].x = -1;
 game->blocks[i][j].y = -1;
 game->blocks[i][j].color =0;
 }
 }

 // 随机生成一个方块 int x, y;
 srand(time(NULL));
 x = rand() % (game->cols -2) +1;
 y = rand() % (game->rows -2) +1;
 game->blocks[x][y].x = x;

}

// 绘制游戏状态void drawGame(Game game) {

// 移动方块void moveBlock(Game *game, int dx, int dy) {

 // 检查是否有行满 if (checkFull(*game)) {
 // 清除行 clearRow(game);
