好的,以下是一个简单的Python实现俄罗斯方块的代码:
```python
import pygame
import random
# 初始化pygame
pygame.init()
# 游戏区域大小
width = 300
height = 600
# 初始化游戏窗口
screen = pygame.display.set_mode((width, height))
pygame.display.set_caption("俄罗斯方块")
# 定义颜色
white = (255, 255, 255)
black = (0, 0, 0)
red = (255, 0, 0)
blue = (0, 0, 255)
green = (0, 255, 0)
# 定义方块大小
block_size = 30
# 定义方块类型及颜色
shapes = [
([(0, 0), (1, 0), (2, 0), (3, 0)], blue), # I型
([(0, 0), (1, 0), (2, 0), (2, 1)], green), # L型
([(0, 0), (1, 0), (2, 0), (2, -1)], red), # J型
([(0, 0), (1, 0), (0, 1), (1, 1)], white), # O型
([(0, 0), (1, 0), (1, 1), (2, 1)], blue), # Z型
([(0, 0), (1, 0), (1, -1), (2, -1)], green), # S型
([(0, 0), (1, 0), (1, 1), (1, -1)], red) # T型
]
# 定义游戏区域及其位置
game_area = [[0 for _ in range(10)] for _ in range(20)]
game_area_pos = (50, 50)
# 定义当前方块及其位置
cur_shape = random.choice(shapes)
cur_pos = [4, 0]
# 定义分数
score = 0
# 定义字体
font = pygame.font.SysFont("arial", 20)
# 定义游戏结束标志
game_over = False
# 检查方块是否越界或与已有方块重叠
def check_collision(board, shape, offset):
for x, y in shape:
x += offset[0]
y += offset[1]
if x < 0 or x >= len(board[0]) or y >= len(board) or board[y][x]:
return True
return False
# 将当前方块放到游戏区域中
def add_to_board(board, shape, offset):
for x, y in shape:
board[y + offset[1]][x + offset[0]] = 1
# 移除已满的行
def remove_full_lines(board):
lines_removed = 0
row = len(board) - 1
while row >= 0:
if all(board[row]):
for r in range(row, 0, -1):
board[r] = board[r - 1][:]
board[0] = [0 for _ in range(len(board[0]))]
lines_removed += 1
else:
row -= 1
return lines_removed
# 旋转方块
def rotate_shape(shape):
return [(-y, x) for x, y in shape]
# 绘制方块
def draw_shape(surface, shape, offset):
for x, y in shape:
pygame.draw.rect(surface, shape[1], (game_area_pos[0] + (offset[0] + x) * block_size,
game_area_pos[1] + (offset[1] + y) * block_size,
block_size, block_size))
pygame.draw.rect(surface, black, (game_area_pos[0] + (offset[0] + x) * block_size,
game_area_pos[1] + (offset[1] + y) * block_size,
block_size, block_size), 1)
# 绘制游戏区域
def draw_game_area(surface, board):
for y, row in enumerate(board):
for x, col in enumerate(row):
if col:
pygame.draw.rect(surface, white, (game_area_pos[0] + x * block_size,
game_area_pos[1] + y * block_size,
block_size, block_size))
pygame.draw.rect(surface, black, (game_area_pos[0] + x * block_size,
game_area_pos[1] + y * block_size,
block_size, block_size), 1)
# 绘制分数
def draw_score(surface, score):
score_text = font.render("Score: " + str(score), True, white)
surface.blit(score_text, (10, 10))
# 主循环
while not game_over:
# 处理事件
for event in pygame.event.get():
if event.type == pygame.QUIT:
game_over = True
elif event.type == pygame.KEYDOWN:
if event.key == pygame.K_SPACE:
cur_shape = (rotate_shape(cur_shape[0]), cur_shape[1])
if check_collision(game_area, cur_shape[0], cur_pos):
cur_shape = (rotate_shape(cur_shape[0]), cur_shape[1])
elif event.key == pygame.K_LEFT:
if not check_collision(game_area, cur_shape[0], (cur_pos[0] - 1, cur_pos[1])):
cur_pos[0] -= 1
elif event.key == pygame.K_RIGHT:
if not check_collision(game_area, cur_shape[0], (cur_pos[0] + 1, cur_pos[1])):
cur_pos[0] += 1
elif event.key == pygame.K_DOWN:
if not check_collision(game_area, cur_shape[0], (cur_pos[0], cur_pos[1] + 1)):
cur_pos[1] += 1
# 将当前方块放到游戏区域中
if check_collision(game_area, cur_shape[0], (cur_pos[0], cur_pos[1] + 1)):
add_to_board(game_area, cur_shape[0], cur_pos)
lines_removed = remove_full_lines(game_area)
score += lines_removed * 10
cur_shape = random.choice(shapes)
cur_pos = [4, 0]
if check_collision(game_area, cur_shape[0], cur_pos):
game_over = True
else:
cur_pos[1] += 1
# 绘制游戏界面
screen.fill(black)
draw_game_area(screen, game_area)
draw_shape(screen, cur_shape[0], cur_pos)
draw_score(screen, score)
pygame.display.update()
# 控制帧率
pygame.time.Clock().tick(10)
# 退出pygame
pygame.quit()
```
运行代码后,即可看到俄罗斯方块的游戏界面。
