如何讓 pacman 中的幽靈移動得更慢？ Python

Question

我在 pygame 寫 pacman。我有鬼移動的問題。 它移動得太快了。 當它以速度 1 移動時，它非常快。 當速度為 0.1 時，我的代碼不起作用。

這是幽靈運動代碼：

#GHOST MOVE
move_list = ['right', 'left', 'up', 'down']
move_chise = random.choice(move_list)
if move_chise == 'right':
    while not sprite.spritecollide(ghost, walls, False):
        ghost.rect.x += speed
    ghost.rect.x -= 2
elif move_chise == 'left':
    while not sprite.spritecollide(ghost, walls, False):
        ghost.rect.x -= speed
    ghost.rect.x += 2
elif move_chise == 'up':
    while not sprite.spritecollide(ghost, walls, False):
        ghost.rect.y -= speed
    ghost.rect.y += 2
elif move_chise == 'down':
    while not sprite.spritecollide(ghost, walls, False):
        ghost.rect.y += speed
    ghost.rect.y -= 2

這是我的所有代碼：

你能說出問題是什么以及我該如何解決嗎？
這是我的游戲的樣子：

Answer 1

問題是您使用while來檢查碰撞 - 因此，在while Game的每個循環中，它都會重復直到發生碰撞。 這會改變變量的值，但不會改變屏幕上的圖像。

在每個while game循環中，您應該只檢查一次碰撞。 並在下一個循環中重復它。 所以你應該使用if而不是while 。

但這還需要其他改變。 你還需要else:當它檢測到碰撞時向后移動，它也應該 select 一個新的方向。

#GHOST MOVE
move_list = ['right', 'left', 'up', 'down']
move_chise = random.choice(move_list)  # first direction at start.

while game:
    for e in event.get():
            if e.type == QUIT:
                exit()

    if move_chise == 'right':
        if not sprite.spritecollide(ghost, walls, False):
            ghost.rect.x += speed
        else:
            ghost.rect.x -= 2
            move_chise = random.choice(move_list)
    elif move_chise == 'left':
        if not sprite.spritecollide(ghost, walls, False):
            ghost.rect.x -= speed
        else:
            ghost.rect.x += 2
            move_chise = random.choice(move_list)
    elif move_chise == 'up':
        if not sprite.spritecollide(ghost, walls, False):
            ghost.rect.y -= speed
        else:
            ghost.rect.y += 2
            move_chise = random.choice(move_list)
    elif move_chise == 'down':
        if not sprite.spritecollide(ghost, walls, False):
            ghost.rect.y += speed
        else:
            ghost.rect.y -= 2
            move_chise = random.choice(move_list)

而不是圖像jpg我使用Surface()填充紅色 - 這樣每個人都可以簡單地復制並運行它而不需要圖像jpg 。

我也改變了：

• 創建牆和硬幣的列表。
• 在某些地方，我檢查rect.bottom ， rect.top而不是rect.y和rect.left ， rect.right而不是rect.x 。
• 在blit()中，我使用player.rect而不是(player.rect.x, player.rect.y) 。
• 添加Player.move()和Enemy.move() 。
• 創造了三個幽靈。
• 從左隧道跳到右隧道。
• 所有對象都使用draw(window)而不是draw() 、 show()或draw_wall() 。
• 所有對象都使用x,y,width,height而不是player_x 、 wall_x等。
• 將顏色設置為元組(R,G,B)而不是分隔值color1, color2, color3 。

Answer 2

由於 while 循環，精靈盡可能向下移動。 這確實使速度變得無關緊要，因為它們確實以該速度移動，直到它們不能再移動每一幀。 因此，您應該刪除 while 循環並將其內容直接放在它們所在的 if 語句中。
