所以我一直试图在pygame中制作一个简单的迷宫游戏。目前，我遇到了墙面碰撞问题：我使用的当前碰撞系统是错误的，并没有按预期工作：
import pygame
import random
# mazes
mazes = [
[
"wwwwwwwwwwwwwwwwwwwwwww",
"w w",
"w D",
"w D",
"w w",
"wwwwwwwwwwwwwwwwwwwwwww"
]
,
[
"wwwwwwwwwwwwwwwwwwwwwww",
"w w w",
"w w wwwwwwwwwwwwwwwww w",
"w w wD w w",
"w w wwwwwwwwwwwwwww w w",
"w w w w",
"w wwwwwwwwwwwwwwwwwww w",
"w w",
"wwwwwwwwwwwwwwwwwwwwwww"
]
]
pygame.init()
# Asset and text properties

screen_text = font.render(msg, True, color)
gameDisplay.blit(screen_text, [x_axis, y_axis])
# Create a game display
gameDisplay = pygame.display.set_mode([display_width, display_height])
pygame.display.set_caption("Mazer - Use arrow keys to move")
def gameloop(): # main function

if event.type == pygame.KEYUP and event.type != pygame.KEYDOWN:

event.key == pygame.K_UP or event.key == pygame.K_RIGHT:

for row in Maze:
for space in row:
if space == "w":
wall_maze = wall(block_size, pos_x, pos_y)
wall_list.add(wall_maze)
elif space == "D":
door_maze = door(block_size, pos_x, pos_y)
door_list.add(door_maze)
pos_x += block_size

pos_x = display_width / 10 - block_size
return wall_list, door_list
gameloop()
如果您尝试运行代码并玩游戏，您会注意到当您移向墙壁时，播放器通常会留在墙内并且控件反转（向左移动时向右移动）。我怀疑它与我构建碰撞探测器的方式有关：
if movementSpeed_x > 0:
if pygame.sprite.spritecollideany(mazer, wall_maze):
movementSpeed_x = 0
player_x -= speed
elif movementSpeed_x < 0:
if pygame.sprite.spritecollideany(mazer, wall_maze):
movementSpeed_x = 0
player_x += speed
if movementSpeed_y > 0:
if pygame.sprite.spritecollideany(mazer, wall_maze):
movementSpeed_y = 0
player_y -= speed
elif movementSpeed_y < 0:
if pygame.sprite.spritecollideany(mazer, wall_maze):
movementSpeed_y = 0
player_y += speed
还有一件事，我认为通过在pygame.display.update（）之前使用此代码，它不会显示玩家撞墙，因为该位置应该在此之前更新但不知何故它没有＆＃ 39;按预期工作。感谢您查看我的代码。
