Python OOP - 足球模拟

Question

我是 OOP 的新手。我想模拟一场足球比赛。如何访问 Player/Offender/Defender 类中的 Play 实例变量？如果其他结构更好，请帮助。

class Player:
    def __init__(self, x, y):
        self.x = x
        self.y = y

    def move_to(self, x, y):
        self.x = (self.x + x) / 2
        self.y = (self.y + y) / 2

    ## Loop through Play.Players to find nearest. How do I access Play.Players?
    def nearest(self):
        return nearest

class Offender(Player):
    def __init__(self, x, y):
        super().__init__(x, y)

    # Move to ball.
    def strategy():
        ball_x = Play.ball_x # how do I access Play.ball_x
        ball_y = Play.ball_y # how do I access Play.ball_y
        self.move_to(ball_x, ball_y)

class Defender(Player):
    def __init__(self, x, y):
        super().__init__(x, y)

    # Move to nearest player
    def strategy(self):
        nearest = self.nearest()
        self.move_to(nearest)          

class Play:
    def __init__(self, offense_players, defense_players, ball_x, ball_y):
        self.offense = [Offender(player) for player in offense_players]
        self.defense = [Defender(player) for player in defense_players]
        self.players = self.offense + self.defense
        self.ball_x = ball_x
        self.ball_y = ball_y

    def simulate(self):
        while True:
            for player in self.players:
                player.strategy()

if __name__ == "__main__":
    Play().simulate()

我没有使用 Offender 和 Defender 类，而是为每个位置设置一个类，即 Striker(Player)、Midfielder( Player), Goalie(Player) 等，这就是为什么我想将他们各自的 strategy 存储在他们的类中而不是 播放类。

不确定这对您有多大帮助，因为实现是用 C++ 实现的
