Question

我在python中编程很新，我决定创建一个python的基本版本的游戏。我在使用A.I时遇到了麻烦，当你运行代码时，红色区块（敌人）会精神错乱，我试图让它追逐玩家。除了我试图让另一个敌人跟随迷宫周围的随机路径，但在我开始发展白发后放弃了。

def move_to_player(self, Player):
    if Player.rect.x > enemy.rect.x:
        enemy.changespeed(1,0)

    elif Player.rect.x < enemy.rect.x:
        enemy.changespeed(-1,0)

    elif Player.rect.y > enemy.rect.y:
        enemy.changespeed(0,1)

    elif Player.rect.y < enemy.rect.y:
        enemy.changespeed(0,-1)

如果有帮助的话，这是正在使用的两个类。任何帮助都将非常感激。

class Player(pygame.sprite.Sprite):


    #must have constructor line, will always be called
    def __init__(self, x, y):
        # Call the parent's constructor
        pygame.sprite.Sprite.__init__(self)

        # Set dimensions of player
        self.image = pygame.Surface([25, 25])
        self.image.fill(white) # fill enitre image with "white"

        # The passed in co-ordinates are top left corner where x and y start
        self.rect = self.image.get_rect()

Answer 1

def move_to_player(self, Player):
    if Player.rect.x > enemy.rect.x:
        enemy.changespeed(1,0)

    elif Player.rect.x < enemy.rect.x:
        enemy.changespeed(-1,0)

    elif Player.rect.y > enemy.rect.y:
        enemy.changespeed(0,1)

    elif Player.rect.y < enemy.rect.y:
        enemy.changespeed(0,-1)

上面的代码是一种逻辑，而不是您已经编写了一组条件以使其以特定方式遵循的AI。

如果您想使用AI，则可能需要研究A-star寻路。这就是当今大多数游戏中所使用的。

此外，关于红色方块的想法。可能是因为您没有正确设置每秒的帧数，所以屏幕获得的更新太多地改变了敌人的动作。
