InputBox isn't a function native to Pygame. Pygame doesn't have any GUI
widgets included; you have to write them yourself, or find one that's written
already. I do recall there have been some unofficial GUI toolkits written for
pygame, but I haven't used them (and in my opinion, they all seem a little
ugly).
However, I found this:
http://www.pygame.org/pcr/inputbox/index.php
And this gives you a simple input box. To put this into your game, copy and
paste the code below:
#######################
def get_key():
while 1:
event = pygame.event.poll()
if event.type == KEYDOWN:
return event.key
else:
pass
def display_box(screen, message):
"Print a message in a box in the middle of the screen"
fontobject = pygame.font.Font(None,18)
pygame.draw.rect(screen, (0,0,0),
((screen.get_width() / 2) - 100,
(screen.get_height() / 2) - 10,
200,20), 0)
pygame.draw.rect(screen, (255,255,255),
((screen.get_width() / 2) - 102,
(screen.get_height() / 2) - 12,
204,24), 1)
if len(message) != 0:
screen.blit(fontobject.render(message, 1, (255,255,255)),
((screen.get_width() / 2) - 100, (screen.get_height() / 2) - 10))
pygame.display.flip()
def ask(screen, question):
"ask(screen, question) -> answer"
pygame.font.init()
current_string = []
display_box(screen, question + ": " + string.join(current_string,""))
while 1:
inkey = get_key()
if inkey == K_BACKSPACE:
current_string = current_string[0:-1]
elif inkey == K_RETURN:
break
elif inkey == K_MINUS:
current_string.append("_")
elif inkey <= 127:
current_string.append(chr(inkey))
display_box(screen, question + ": " + string.join(current_string,""))
return string.join(current_string,"")
######################
Then to ask a person's name, use:
name = ask(screen, "Your name")
