Question

这是我的代码：

import pygame, pygame.font, pygame.event, pygame.draw, string
from pygame.locals import *

counter = 0


def get_key():
    global counter
    while 1:
        event = pygame.event.poll()
        if event.type == KEYDOWN:
            return event.key
        else:
            pass


def display_box(screen, message):
    global counter
    "Print a message in a box in the middle of the screen"
    fontobject = pygame.font.Font(None, 18)
    pygame.draw.rect(screen, (255, 255, 255),
                     ((screen.get_width() / 2) - 100,
                      (screen.get_height() / 2) - 10,
                      200, 20), 1)
    pygame.draw.rect(screen, (0, 0, 0),
                     ((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):
    global counter
    str_counter = str(counter)
    "ask(screen, question) -> answer"
    pygame.font.init()
    current_string = []
    display_box(screen, "comment" + ": " + 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_SPACE:

            screen = screen + str_counter
            counter = counter + 1

        elif inkey <= 127:
            current_string.append(chr(inkey))
        display_box(screen, "comment" + ": " + string.join(current_string, ""))
    return string.join(current_string, "")


def main():
    global counter
    screen = pygame.display.set_mode((300, 100))
    print ask(screen)


if __name__ == '__main__': main()

您收到的错误是第49行导致您正在执行操作screen = screen + str_counter，它正在尝试添加一个pygame.Surface对象和一个无法一起添加的字符串对象。

此外，pygames不是经常构建的，以便能够同时处理多个窗口的运行。如果你想在pygames中运行多个窗口，你需要使用多处理或其他可以运行多个窗口的模块，例如pyglet或cocos2d。

我希望每当我按下SPACE时，都会弹出一个新的pygame窗口。但是每当我按SPACE时，程序都会出现一些错误
