3. Inputbox

Creating inputbox, a box where you can write text is relatively simple.

Just capture pygame.KEYDOWN event and it provides two handy attributes. First one is event.key which returns which key was pressed down and second is event.unicode. event.unicode is set when value is printable unicode charater. This provides easy way to filter visible characters and other keys.

In the following program you can type text and remove chars with backspace. You can print contents for text by hitting enter.

import sys
import pygame

window = pygame.display.set_mode((640, 480))
clock = pygame.time.Clock()

font = pygame.font.SysFont(pygame.font.get_default_font(), 32)

input_string = ""
input_surface = font.render(input_string, True, (255, 255, 255))

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

        if event.type == pygame.KEYDOWN:
            if event.unicode:
                input_string += event.unicode
                if event.key == pygame.K_BACKSPACE:
                    input_string = input_string[:-1]
                if event.key == pygame.K_RETURN:
                    print(f"You typed: '{input_string}'")

            input_surface = font.render(input_string, False, (255, 255, 255))

    window.fill((0, 0, 0))

    pygame.draw.rect(window, (127, 127, 127), ((8, 8), (250, 28)) )
    window.blit(input_surface, (10, 10))


This program doesn’t work with devices that uses on-screen keyboards or touch events.
