How can I update pygame window from another script?-CodePudding

import pygame
import sys

pygame.init()
win = pygame.display.set_mode((400, 140))

font = pygame.font.SysFont('Arial', 50)


def getKey(keyInput):
    if keyInput[119]:  # W

    else:

        win.blit(font.render('▲', True, (0, 0, 0)), (282, 5))

    if keyInput[1073741904]:  # LEFT
        pygame.draw.rect(win, [220, 30, 30], pygame.Rect(205, 70, 60, 60))

    else:
        pygame.draw.rect(win, [255, 100, 0], pygame.Rect(335, 70, 60, 60))

    pygame.display.update()


keyList = [97, 100, 115, 119, 1073741904, 1073741906, 1073741905, 1073741903]
reset = True

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

    keyInput = pygame.key.get_pressed()
    flag = [True if keyInput[i] == 1 else False for i in keyList]

    if True in flag:
        reset = True
        getKey(keyInput)
    else:
        if reset:
            getKey(keyInput)
            reset = False
        else:
            pass

I want to separate "getKey" function from my script and use it from another script. Actually I can seperate it but I don't know how can I update pygame window from another script by using this getKey function. What should I do?

For example:

main.py--

import pygame
import sys
import getKeyFunction 

pygame.init()
win = pygame.display.set_mode((400, 140))

keyList = [97, 100, 115, 119, 1073741904, 1073741906, 1073741905, 1073741903]
reset = True

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

    keyInput = pygame.key.get_pressed()
    flag = [True if keyInput[i] == 1 else False for i in keyList]

    if True in flag:
        reset = True
        getKey(keyInput)
    else:
        if reset:
            getKey(keyInput)
            reset = False
        else:
            pass

Main.py just start pygame window but the other script which contain getKey function update this window.

CodePudding user response：

You need to pass win to the getKey function:

def getKey(win, keyInput):
    # [...]

while True:
    # [...]

    if True in flag:
        reset = True
        getKey(win, keyInput)

    # [...]
