好吧，我试图用pygame创建一个pacman，但我无法弄清楚如何对鬼魂和pacman进行迫害。我试过这个：
if keyup == True:
y_position_pacman -= 1
pygame.time.wait(50)
y_position_ghost -= 1
它没有按照我想要的方式工作，只是落后于游戏。我想要的是幽灵跟随玩家。一个重要的观察是鬼需要找到玩家，而不仅仅是模仿他。我试图这么做很多时间，但我无法弄清楚如何做到这一点，帮助？
更新：我不知道是否有任何问题，但我是巴西人。所以我的代码是葡萄牙语。 Fanstasma是葡萄牙语中的幽灵，如果有帮助的话。 Paracima是键盘的变量，parabaixo，direita和esquerda分别用于向下，向右和向左。这是我的全部代码：

time.wait（50）将整个程序停止50毫秒，这样就无法工作了。如果你的程序有一个主循环，那么在每个第10或第n个循环中如何执行ghost跟随运动？

我首先想到的是，这里提出的问题是为什么比赛落后，因此另一个帖子。这篇文章包含了关于敌人幽灵寻找pacman玩家的信息。
<小时/> 你可以朝着pacman的方向移动幽灵。 （与答案中的解决方案不同，它将鬼魂移动到pacman给出的相同运动）。 通过这个，我的意思是如果pacman在幽灵的右边，鬼魂每一帧向右移动，直到它在pacman之上。编码示例如下：
def pathfindToPlayer():
# X and Y are the ghost's location attributes
pac_x, pac_y = pacman.x, pacman.y # Pacman's location attributes
tomove_x = pac_x-self.x # Get difference between x locations
tomove_x = cmp(abs(tomove_x), tomove_x) # Normalize to positive/negative 1
# repeat with y values
tomove_y = pac_y-self.y
tomove_y = cmp(abs(tomove_y), tomove_y)
# apply location offsets to ghost
if tomove_x != 0: # try to move x before y, diagonal moves not allowed
self.x += tomove_x
else:
self.y += tomove_y
<小时/> 这个解决方案涉及使用实际地图来确定它可以和不能移动的位置，同时仍然朝着pacman方向移动。
gamemap = [
[0, 0, 0, 0, 0 ],
['p', 0, 0, 0, 0 ],
[0, 1, 1, 1, 0 ],
[0, 0, 0, 1, 0 ],
[0, 0, 0, 1,'g' ]
]
def pathfindToPlayer():
'''
Same stuff here as the above function, without applying the offsets yet
'''
if gamemap[self.x+tomove_x][self.y] != 1: # If there isn't a wall
self.x += tomove_x
elif gamemap[self.x][self.y+tomove_y] != 1: # If there isn't a wall
self.y += tomove_y
else:
print "Can't move closer to Pacman"
<小时/> 如果上述两种解决方案不够强大，无法满足您的需求，那么您可以使用众多寻路算法中的一种。我之所以选择上述两种解决方案的原因是因为它们很简单，很容易适应答案而不需要太多解释。

答案 2 :(得分：0)
视觉游戏的事情是有一个叫做游戏循环的主要块。没有不同的线程或进程处理游戏逻辑，比如你提出的幽灵运动，那么你就不应该做任何阻止代码的事情。你想要做的是每隔帧更新幽灵的位置，而不是等待一定的时间。例如：
def gameLogic(keysPressed):
if keysPressed["up"]: # Only one case for the movement, the rest is common sense
y_position_pacman -= 1
ghost.pathfindTo(id="player") # You'll have to implement this method yourself
# Main game loop
while gameRunning:
keysPressed = handleInput()
gameLogic(keysPressed)
render()
fpsClock.tick(60) # Tick the created fpsClock object to limit the game to 60 fps
