我在整个互联网上进行了搜索并研究了为什么我的 pygame 在与我在游戏中的墙碰撞时不会移动我的 Sprite 。每当玩家与 wall_list( Sprite 组)中的墙发生碰撞时，我都会让碰撞检测循环打印出“hit2”。相反，它只是从外观上检测到墙壁正在碰撞，而不是在玩家与墙壁碰撞时检测到。
任何人都可以再看看这个并告诉我我做错了什么吗？

最佳答案
您必须移动播放器的 self.rect，因为它用于碰撞检测。如果您只想以整数步移动，可以删除 self.x, self.y 属性，只使用 self.rect 来存储坐标。
我还改变了一些东西:
- 我将事件循环中的前一个事件传递给玩家，否则将一直使用最后一个全局事件变量。将
p1.keys(event)调用移动到事件循环中。 - 要在碰撞后重置位置，您只需将玩家向后移动一步即可。
- 我已经清理了代码的绘图部分(有两个
pygame.display.update()调用，你 blit 播放器两次。
class Player(pygame.sprite.Sprite):
"""Spawn a player."""
def __init__(self):
self.image = draw_me # Assign the player image.
# Assign the topleft coords of the rect.
self.rect = self.image.get_rect(topleft=(450, 685))
# The direction should be an instance attribute not a global variable.
self.direction = None
def keys(self, event):
"""Control player movement."""
if event.type == pygame.KEYDOWN:
if event.key in (pygame.K_LEFT, pygame.K_a):
self.direction = "left"
self.rect.x += -steps
elif event.key in (pygame.K_RIGHT, pygame.K_d):
self.direction = "right"
self.rect.x += steps
elif event.key in (pygame.K_UP, pygame.K_w):
self.direction = "up"
self.rect.y += -steps
elif event.key in (pygame.K_DOWN, pygame.K_s):
self.direction = "down"
self.rect.y += steps
print(self.direction)
修改后的主循环:
# I added a wall at the start to test the collisions.
wall5 = Wall(420, 670, 50, 5)
wall_list.add(wall5)
clock = pygame.time.Clock() # A clock to limit the frame rate.
main = True
while main:
for event in pygame.event.get():
if event.type == pygame.QUIT:
main = False
# Pass the previous event to the player in the event loop
# (once per event not per frame).
p1.keys(event)
if pygame.sprite.spritecollide(p1, wall_list, False):
print("sprites have collided!")
# Move the player back one step if a collision occurred.
if p1.direction == "left":
p1.rect.x += steps
elif p1.direction == "right":
p1.rect.x -= steps
elif p1.direction == "up":
p1.rect.y += steps
elif p1.direction == "down":
p1.rect.y -= steps
screen = pygame.display.set_mode((mapwidth * tilesize, mapheight * tilesize))
for row in range(mapheight):
for column in range(mapwidth):
backdrop1 = pygame.draw.rect(screen, colours[tilemap[row][column]],

backdrop = backdrop1
screen.blit(draw_me2, (c1.x, c1.y))
screen.blit(draw_monsters, (m1.x, m1.y))
screen.blit(draw_monsters, (m2.x, m2.y))
screen.blit(draw_monsters, (m3.x, m3.y))
wall_list.draw(screen)
# Blit the player image at the player rect.
screen.blit(p1.image, p1.rect)
# Test if the player rect moves correctly.
pygame.draw.rect(screen, (255, 0, 0), p1.rect, 1)
pygame.display.update() # Call `display.update` only once per frame.
clock.tick(60) # Limit the frame rate to 60 FPS.
