问题描述

我正在尝试在我的游戏中放置一个播放按钮。当我启动游戏时,我点击播放按钮,它给了我一个错误

Traceback (most recent call last):
   File "C:\Users\Zee_S\OneDrive\Desktop\python projects\lil Shooter\Player\Lil Shooter.py", line 370, in <module>
   game_intro()
   File "C:\Users\Zee_S\OneDrive\Desktop\python projects\lil Shooter\Player\Lil Shooter.py", line 336, in game_intro
   button("LETS PLAY!", 20, 450, 115, 50, green, bright_green, run)
   File "C:\Users\Zee_S\OneDrive\Desktop\python projects\lil Shooter\Player\Lil Shooter.py", line 308, in button
   action()
TypeError: 'bool' object is not callable
[Finished in 8.3s]

我已经查看了这个'bool'东西的代码,但我找不到任何东西。这是按钮和标题屏幕的代码

def text_objects(text, font):
    textSurface = font.render(text, True, black)
    return textSurface, textSurface.get_rect()

def button(msg, x, y, w, h, ic, ac, action=None):
    mouse = pygame.mouse.get_pos()
    click = pygame.mouse.get_pressed()

    if x + w > mouse[0] > x and y + h > mouse[1] > y:
        pygame.draw.rect(screen, ac, (x, y, w, h))
        if click[0] == 1 and action != None:
            action()
    else:
        pygame.draw.rect(screen, ic, (x, y, w, h))
    smallText = pygame.font.SysFont("comicsansms", 20)
    textSurf, textRect = text_objects(msg, smallText)
    textRect.center = ((x + (w / 2)), (y + (h / 2)))
    screen.blit(textSurf, textRect)

def quitgame():
    pygame.quit()
    quit()

def game_intro():
    intro = True

    while intro:
        for event in pygame.event.get():
            # print(event)
            if event.type == pygame.QUIT:
                pygame.quit()
                quit()

        screen.fill(white)
        largeText = pygame.font.SysFont("comicsansms", 115)
        TextSurf, TextRect = text_objects("Lilshooter", largeText)
        TextRect.center = ((display_width / 2), (display_height / 2))
        screen.blit(TextSurf, TextRect)

        button("LETS PLAY!", 20, 450, 115, 50, green, bright_green, run)
        button("Quit", 480, 450, 100, 50, red, bright_red, quitgame)

        pygame.display.update()
        clock.tick(15)

这就是我在游戏循环中调用它的地方

run = True
game_intro()
while run:
    [...]

我能得到帮助来解决这个问题吗

解决方案


函数的最后一个参数button必须是函数。因此它不可能是run因为run是一个布尔值。

如果要在intro按下按钮时更改变量的状态,请编写一个startGame函数:

def startGame():
    global intro
    intro = False

传递startGamebutton, 而不是run:

button("LETS PLAY!", 20, 450, 115, 50, green, bright_green, startGame)

注意变量intro必须是全局命名空间中的变量:(
global语句

intro = True
def game_intro():
    global intro

    while intro:   
        # [...]
