当我将角色移到x_cor:0时,我希望玩家将他移过x_cor 0时反弹。相反,它什么也没做。
我已经尝试过使用move_right函数来不断将播放器移回去,但它不起作用。

我希望我的玩家在x_cor为0时向右移动。相反,玩家只是正常移动。
最佳答案
将播放器播放器准确地放在屏幕的中央)参见pygame.Rect
):
class Player(pygame.sprite.Sprite):
def __init__(self):
pygame.sprite.Sprite.__init__(self)
self.image = player_img
self.rect = self.image.get_rect()
self.rect.center = (x_size // 2, y_size // 2) # center of the screen
当您向左移动
x_cor_player
小于0时,将播放器向右移动:if event.type == KEYDOWN:
# [...]
if event.key == K_a:
for food in all_food:
food.move_left()
x_cor_player += -20
if x_cor_player < 0:
player.move_right()
如果您向右移动并且播放器的位置不在中心,请向左移动播放器:
if event.type == KEYDOWN:
# [...]
if event.key == K_d:
for food in all_food:
food.move_right()
x_cor_player += 20
if player.rect.centerx > x_size // 2:
player.move_left()
