编程怎么让人移动方块

时间:2025-01-26 13:57:08 网络游戏

要让方块在屏幕上移动,你需要使用编程语言来控制方块的坐标,并在用户按下键盘时更新这些坐标。以下是一个使用Python和Pygame库实现方块移动的基本示例:

初始化游戏窗口和设置

```python

import pygame

pygame.init()

screen = pygame.display.set_mode((800, 600))

pygame.display.set_caption('移动方块游戏')

```

定义方块的形状和初始位置

```python

SHAPES = [

[[1, 1, 1, 1]], I型方块

[[1, 1], [1, 1]], O型方块

[[1, 1, 0], [0, 1, 1]], Z型方块

添加更多形状...

]

class Block:

def __init__(self):

self.shape = random.choice(SHAPES)

self.color = random.choice([255, 0, 0]) 红色方块

self.x = (screen.get_width() - len(self.shape)) // 2

self.y = 0

```

处理用户输入

```python

running = True

direction = 'right'

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_UP:

direction = 'up'

elif event.key == pygame.K_DOWN:

direction = 'down'

elif event.key == pygame.K_LEFT:

direction = 'left'

elif event.key == pygame.K_RIGHT:

direction = 'right'

```

移动方块

```python

def move_block(block, direction):

if direction == 'left':

block.x -= 30

elif direction == 'right':

block.x += 30

elif direction == 'up':

block.y -= 30

elif direction == 'down':

block.y += 30

防止方块移出屏幕

if block.x < 0:

block.x = 0

elif block.x + len(block.shape) > screen.get_width():

block.x = screen.get_width() - len(block.shape)

if block.y < 0:

block.y = 0

elif block.y + len(block.shape) > screen.get_height():

block.y = screen.get_height() - len(block.shape)

```

更新和绘制方块

```python

screen.fill((255, 255, 255)) 清屏

for block in blocks:

for row in block:

pygame.draw.rect(screen, block.color, pygame.Rect(block.x, block.y, len(row), len(row)))

move_block(blocks, direction) 假设只有一个方块

pygame.display.flip()

```

主循环

```python

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_UP:

direction = 'up'

elif event.key == pygame.K_DOWN:

direction = 'down'

elif event.key == pygame.K_LEFT:

direction = 'left'

elif event.key == pygame.K_RIGHT:

direction = 'right'

screen.fill((255, 255, 255)) 清屏

for block in blocks:

for row in block:

pygame.draw.rect(screen, block.color, pygame.Rect(block.x, block.y, len(row), len(row)))

move_block(blocks, direction) 假设只有一个方块

pygame.display.flip()

```
