Keys in Pygame instead of numbers in the actual key-CodePudding

I want to make a menu point where I can change the hotkeys and also show which are used, but when I put them into a variable the output is in numbers. I had the idee to set the varibles when pressing the key as following:

if event.key == pygame.K_d:
    varibleright = d

This I would have to do for all the keys is there a better way or should I just do it for all the keys?

CodePudding user response：

The KEYDOWN and KEYUP event provides the unicode attribute (see pygame.event module). The unicode attribute provides the Unicode representation of the keyboard input. A user friendly name of a key can be get by pygame.key.name():

if event.type == pygame.KEYDOWN:
    print(event.unicode)
    print(pygame.key.name(event.key))

You can use the functions to compare the key with a unicode character or string:

if event.type == pygame.KEYDOWN:
    if event.unicode == 'a':
        print('a')

if event.type == pygame.KEYDOWN:
    if pygame.key.name(event.key) == 'd':
        print('d')
    if pygame.key.name(event.key) == 'right':
        print('right')

This allows you to define variables for the keys

key_up = 'up'
key_down = 'down'

if event.type == pygame.KEYDOWN:
    if pygame.key.name(event.key) == key_up:
        print('move up')
    if pygame.key.name(event.key) == key_down:
        print('move down')

Minimal example:

import pygame

pygame.init()
window = pygame.display.set_mode((400, 400))
clock = pygame.time.Clock()

rect = pygame.Rect(190, 190, 20, 20)
key_left = 'left'
key_right = 'right'
key_up = 'up'
key_down = 'down'

run = True
while run:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False 
        if event.type == pygame.KEYDOWN:
            if event.type == pygame.KEYDOWN:
                if pygame.key.name(event.key) == key_left:
                    rect.x -= 20
                if pygame.key.name(event.key) == key_right:
                    rect.x  = 20
                if pygame.key.name(event.key) == key_up:
                    rect.y -= 20
                if pygame.key.name(event.key) == key_down:
                    rect.y  = 20

    window.fill(0)
    pygame.draw.rect(window, 'red', rect)
    pygame.display.flip()
    clock.tick(60)

pygame.quit()
exit()
