Cannot get pygame.JOYBUTTONDOWN to register

[BashBedlam]

Try initializing the joystick individually. Assuming that it's in the zero position, this should work.

joystick_0 = pg.joystick.Joystick (0)
joystick_0 .init()

This works on my system when only one joystick is plugged in.

import pygame as pg
 
pg.init()
joystick_0 = pg.joystick.Joystick (0)
joystick_0 .init()
 
screen = pg.display.set_mode((500,500))
 
running = True
 
while running:
	for event in pg.event.get():
		if event.type == pg.QUIT:
			running = False
		if event.type == pg.JOYBUTTONDOWN:
			print("button down")
		if event.type == pg.JOYBUTTONUP:
			print("button up")
			 
	screen.fill((255,255,255))
	pg.display.update()
             
pg.quit()

Output:
pygame 2.0.1 (SDL 2.0.14, Python 3.8.10)
