在此处输入图像描述所以我正在尝试制作一个塔防游戏，并且我正在尝试将我的玩家移动到一条路径上，但是我遇到了问题

所以我试图做到这一点，所以每次玩家到达那个点时，它都会移动另一个方向 x 或 y 但这正在发生视频

我不知道如何让敌人在路上移动，但这是我的第一次尝试


    # move the enemy
    if playerman.x < 380:
        playerman.x += playerman.speed
    else:
        playerman.y -= playerman.speed

    if playerman.y  > 116:
        playerman.x += playerman.speed

    else:
        playerman.x -= playerman.speed

我的完整代码


import pygame,random

pygame.init()

# window
window = pygame.display.set_mode((1000,700))


#
class player:
    def __init__(self,x,y,height,width,color):
        self.x = x
        self.y = y
        self.height = height
        self.width = width
        self.color = color
        self.speed = 3
        self.rect = pygame.Rect(x,y,height,width)
        self.image = pygame.image.load("weak1.png")
    def draw(self):
        self.rect.topleft = (self.x,self.y)
        pygame.draw.rect(window,self.color,self.rect,2)
        player_rect = self.image.get_rect(center = self.rect.center) 
        player_rect.centerx += 3 # 10 is just an example
        player_rect.centery += -10 # 15 is just an example
        window.blit(self.image, player_rect)


# check points for the player to turn
class check():
    def __init__(self,x,y,height,width,color):
        self.x = x
        self.y = y
        self.height = height
        self.width = width
        self.color = color
        self.rect = pygame.Rect(x,y,height,width)
    def draw(self):
        self.rect.topleft = (self.x,self.y)
        pygame.draw.rect(window,self.color,self.rect)

red = (0,255,0)
check1 = check(380,376,50,50,red)
check2 = check(380,116,50,50,red)
check3 = check(628,116,50,50,red)
check4 = check(640,546,50,50,red)



checks = [check1,check2,check3,check4]

# player
white = (255,255,255)
playerman = player(50,376,50,50,white)


# the background for my gameee
bg = pygame.image.load("bg.png")


# redraw window
def draw():
    window.fill((0,0,0))
    window.blit(bg,(0,0))
    playerman.draw()

    # the check points
    for check in checks:
        check.draw()

# the main loop
runninggame = True
while runninggame:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            runninggame = False


    # move the enemy
    if playerman.x < 380:
        playerman.x += playerman.speed
    else:
        playerman.y -= playerman.speed

    if playerman.y  > 116:
        playerman.x += playerman.speed

    else:
        playerman.x -= playerman.speed

        
    


    # redraw the window
    draw()


    pygame.display.update()
pygame.quit()

您已经实施了 2 个if--statemsts else。

if playerman.x < 380:
   playerman.x += playerman.speed
else:
   playerman.y -= playerman.speed

if playerman.y  > 116:
   playerman.x += playerman.speed

else:
   playerman.x -= playerman.speed

两个语句都被执行，并且玩家在每一帧中执行 2 次动作。

您必须实现单个if--elif语句，其中每帧仅执行 1 个案例。例如：

while runninggame:
    # [...]

    if playerman.x < 380:
        playerman.x += playerman.speed
    elif playerman.y > 116 and playerman.x < 628:
        playerman.y -= playerman.speed
    elif playerman.x < 628:
        playerman.x += playerman.speed
    elif playerman.y < 546:
        playerman.y += playerman.speed
    elif playerman.x < 900:
        playerman.x += playerman.speed

    # [...]
