pygame做随机沙盘高难度迷宫游戏+计时器

以下是一个使用 `pygame` 实现的随机沙盘高难度迷宫游戏，并带有计时器功能的完整代码示例： ```python import pygame import random import time # 初始化 Pygame pygame.init() # 设置窗口大小和标题 WIDTH, HEIGHT = 800, 600 screen = pygame.display.set_mode((WIDTH, HEIGHT)) pygame.display.set_caption("随机沙盘高难度迷宫游戏") # 定义颜色 WHITE = (255, 255, 255) BLACK = (0, 0, 0) RED = (255, 0, 0) GREEN = (0, 255, 0) # 迷宫参数 CELL_SIZE = 20 ROWS = HEIGHT // CELL_SIZE COLS = WIDTH // CELL_SIZE # 计时器 start_time = None # 创建迷宫 class Maze: def __init__(self, rows, cols): self.rows = rows self.cols = cols self.grid = [[Cell(x, y) for y in range(cols)] for x in range(rows)] self.generate_maze(0, 0) def generate_maze(self, x, y): stack = [(x, y)] visited = set() visited.add((x, y)) while stack: current = stack[-1] neighbors = self.get_unvisited_neighbors(current[0], current[1], visited) if neighbors: next_cell = random.choice(neighbors) self.remove_wall(current[0], current[1], next_cell[0], next_cell[1]) visited.add(next_cell) stack.append(next_cell) else: stack.pop() def get_unvisited_neighbors(self, x, y, visited): directions = [(-1, 0), (1, 0), (0, -1), (0, 1)] neighbors = [] for dx, dy in directions: nx, ny = x + dx * 2, y + dy * 2 if 0 <= nx < self.rows and 0 <= ny < self.cols and (nx, ny) not in visited: neighbors.append((nx, ny)) return neighbors def remove_wall(self, x1, y1, x2, y2): mid_x = (x1 + x2) // 2 mid_y = (y1 + y2) // 2 self.grid[mid_x][mid_y].walls = False def draw(self, screen): for row in self.grid: for cell in row: cell.draw(screen) class Cell: def __init__(self, x, y): self.x = x self.y = y self.walls = True def draw(self, screen): if self.walls: rect = pygame.Rect(self.y * CELL_SIZE, self.x * CELL_SIZE, CELL_SIZE, CELL_SIZE) pygame.draw.rect(screen, BLACK, rect) else: rect = pygame.Rect(self.y * CELL_SIZE, self.x * CELL_SIZE, CELL_SIZE, CELL_SIZE) pygame.draw.rect(screen, WHITE, rect) # 主程序 def main(): global start_time maze = Maze(ROWS, COLS) player_pos = [1, 1] end_pos = [ROWS - 2, COLS - 2] running = True start_time = time.time() while running: screen.fill(BLACK) maze.draw(screen) # 绘制玩家 player_rect = pygame.Rect(player_pos[1] * CELL_SIZE, player_pos[0] * CELL_SIZE, CELL_SIZE, CELL_SIZE) pygame.draw.rect(screen, RED, player_rect) # 绘制终点 end_rect = pygame.Rect(end_pos[1] * CELL_SIZE, end_pos[0] * CELL_SIZE, CELL_SIZE, CELL_SIZE) pygame.draw.rect(screen, GREEN, end_rect) # 显示计时器 elapsed_time = int(time.time() - start_time) font = pygame.font.Font(None, 36) text = font.render(f"Time: {elapsed_time} seconds", True, WHITE) screen.blit(text, (10, 10)) for event in pygame.event.get(): if event.type == pygame.QUIT: running = False keys = pygame.key.get_pressed() if keys[pygame.K_UP] and maze.grid[player_pos[0] - 1][player_pos[1]].walls is False: player_pos[0] -= 1 if keys[pygame.K_DOWN] and maze.grid[player_pos[0] + 1][player_pos[1]].walls is False: player_pos[0] += 1 if keys[pygame.K_LEFT] and maze.grid[player_pos[0]][player_pos[1] - 1].walls is False: player_pos[1] -= 1 if keys[pygame.K_RIGHT] and maze.grid[player_pos[0]][player_pos[1] + 1].walls is False: player_pos[1] += 1 # 检查是否到达终点 if player_pos == end_pos: print(f"恭喜！你完成了迷宫，用时 {elapsed_time} 秒") running = False pygame.display.flip() pygame.quit() if __name__ == "__main__": main() ``` ### 上述代码解释： 1. **迷宫生成**：我们使用了递归回溯算法（深度优先搜索）来生成迷宫。每个单元格可以看作一个节点，通过随机选择未访问过的邻居并移除墙壁来构建路径。 2. **计时器**：使用 Python 的 `time` 模块记录玩家从开始到完成迷宫所花费的时间。 3. **玩家移动**：玩家可以通过键盘的方向键（上、下、左、右）进行移动，但只能在没有墙壁的地方移动。 4. **终点检测**：当玩家到达指定的终点位置时，游戏结束并显示完成时间。 --- ###
