如何在pygame中为矩形指定唯一值？

Question

在过去的一周里，我下载了pygame，并尝试制作不同的游戏，主要遵循教程。作为一个项目理念，我决定制作一个游戏/模拟，让老鼠和老鹰在屏幕上四处移动，进食、繁殖并试图生存

游戏的一个重要部分是，每只鼠标都必须有各自的信息，比如健康、饥饿和年龄的变量。然而，使用我目前的代码，我不知道我将如何做到这一点，因为我希望有新的老鼠产卵，并添加到列表中的所有老鼠时，某些事件发生，他们的个人信息

换句话说，我在问如何给每个“给定的鼠标”唯一的变量，必要时可以更改这些变量

我一直在尝试不同的方法，并做了一些谷歌搜索，但我还没有遇到soloution，提前感谢

这是我目前的代码：

import pygame
import time
import random
import sys
import os


def mouse_animation(given_mouse):
    global mouse_movement_counter, can_move_left, can_move_right, can_move_up, can_move_down


    if given_mouse.x <= 20:
        can_move_left = False

    if given_mouse.x >= 1100:
        can_move_right = False

    if given_mouse.y <= 20:
        can_move_up = False

    if given_mouse.y >= 600:
        can_move_down = False


    direction = random.randint(1, 4)

    if direction == 1 and mouse_movement_counter <= 0 and can_move_right:

        given_mouse.x += 60
        mouse_movement_counter += 30
        

    elif direction == 2 and mouse_movement_counter <= 0 and can_move_up: #UP

        given_mouse.y -= 60
        mouse_movement_counter += 30
        

    elif direction == 3 and mouse_movement_counter <= 0 and can_move_down:  # DOWN

        given_mouse.y += 60
        mouse_movement_counter += 30
        

    elif direction == 4 and mouse_movement_counter <= 0 and can_move_left:  # LEFT

        given_mouse.x -= 60
        mouse_movement_counter += 30
        
    elif direction == 5 and mouse_movement_counter <= 0:
        mouse_movement_counter += 30
    else:
        mouse_movement_counter -= 1

        

    
    pygame.display.update()


def random_postion():
    global x_location, y_location
    randomx_postion = random.randint(1,6)
    if randomx_postion == 1:
        x_location = 60
    if randomx_postion == 2:
        x_location = 120
    if randomx_postion == 3:
        x_location = 180
    if randomx_postion == 4:
        x_location = 240
    if randomx_postion == 5:
        x_location = 300
    if randomx_postion == 6:
        x_location = 360

    randomy_postion = random.randint(1,6)

    if randomy_postion == 1:
        y_location = 60
    if randomy_postion == 2:
        y_location = 120
    if randomy_postion == 3:
        y_location = 180
    if randomy_postion == 4:
        y_location = 240
    if randomy_postion == 5:
        y_location = 300
    if randomy_postion == 6:
        y_location = 360

        mouse_animation(mice[mouse_loop])
        mouse_loop += 1

    pygame.display.flip()

我可以想到三种方法。第一个是使用鼠标类

class Mouse:
    def __init__(self, age, health, hunger):
        self.age = age
        self.health = health
        self.hunger = hunger

mice = []
if some_event_happens:
    mice.append(Mouse(some_age, some_health, some_hunger))

如果您还不熟悉类，可以使用二维数组

mice = []
if some_event_happens:
    mice.append([some_age, some_health, some_hunger])

mice[index]允许您访问每个鼠标mice[index][0]是该指数下的小鼠年龄，mice[index][1]是该指数下的小鼠健康状况，[index][2]是该指数下的小鼠饥饿感

第三种方法是使用dictionary

mice = []
if some_event_happens:
    mice.append({"age": some_age, "health": some_health, "hunger": some_hunger})

我个人更喜欢使用这个二维数组，因为索引的含义没有歧义，因为使用的是单词而不是更清晰的数字。范例

mice[index]["age"]
