俄罗斯方块旋转实现详解
俄罗斯方块(Tetris)是一款经典的益智游戏,其核心玩法之一就是通过旋转方块来填满游戏区域。本文将详细介绍俄罗斯方块中旋转功能的实现原理和代码实现,帮助开发者更好地理解这一经典游戏机制。
旋转方块时,需要考虑以下因素:
以下是一个简单的俄罗斯方块旋转功能的实现示例,使用Python语言和Pygame库:
```python
import pygame
import random
初始化Pygame
pygame.init()
设置窗口大小
screen = pygame.display.set_mode((300, 600))
设置颜色
WHITE = (255, 255, 255)
BLACK = (0, 0, 0)
设置方块大小
BLOCK_SIZE = 30
设置游戏区域
GAME_WIDTH = 10
GAME_HEIGHT = 20
创建游戏板
game_board = [[0] GAME_WIDTH for _ in range(GAME_HEIGHT)]
创建方块类
class Tetromino:
def __init__(self, shape, color):
self.shape = shape
self.color = color
self.x = 4
self.y = 0
def rotate(self):
旋转方块
new_shape = [[self.shape[j][i] for j in range(len(self.shape))] for i in range(len(self.shape[0])-1, -1, -1)]
return new_shape
def check_collision(self, new_shape):
检测旋转后是否发生碰撞
for i in range(len(new_shape)):
for j in range(len(new_shape[0])):
if new_shape[i][j] != 0 and (self.x + j = GAME_WIDTH or self.y + i = GAME_HEIGHT or game_board[self.y + i][self.x + j] != 0):
return True
return False
创建方块实例
tetromino = Tetromino([[1, 1, 1, 1]], (255, 0, 0))
游戏主循环
running = True
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
elif event.type == pygame.KEYDOWN:
if event.key == pygame.K_LEFT:
tetromino.x -= 1
elif event.key == pygame.K_RIGHT:
tetromino.x += 1
elif event.key == pygame.K_DOWN:
tetromino.y += 1
elif event.key == pygame.K_UP:
new_shape = tetromino.rotate()
if not tetromino.check_collision(new_shape):
tetromino.shape = new_shape
绘制游戏板
screen.fill(BLACK)
for i in range(GAME_HEIGHT):
for j in range(GAME_WIDTH):
if game_board[i][j] != 0:
for i in range(len(tetromino.shape)):
for j in range(len(tetromino.shape[0])):
if tetromino.shape[i][j] != 0:
pygame.display.flip()
pygame.quit()
