如何在PyGame中检测游戏运行时的控制器

import pygame
import sys

pygame.init()
window_size = (800, 600)
screen = pygame.display.set_mode(window_size)

while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()

    # 检测已连接的控制器
    for i in range(pygame.joystick.get_count()):
        joystick = pygame.joystick.Joystick(i)
        joystick.init()

        # 获取控制器的名称
        joystick_name = joystick.get_name()

        # 获取控制器的轴、按钮数量
        axes_count = joystick.get_numaxes()
        buttons_count = joystick.get_numbuttons()

        # 获取控制器的轴值
        for axis in range(axes_count):
            axis_value = joystick.get_axis(axis)

        # 获取控制器的按钮状态
        for button in range(buttons_count):
            button_state = joystick.get_button(button)
