Question

我一直收到错误＆＃34;字体未初始化＆＃34;运行我的程序后。这是该计划。我知道我正在初始化pygame。我尝试过同时初始化pygame，pygame.font和它们两者。我做了一切。我尝试过将pygames默认字体用作pygame.font.Font（＆＃39; freesansbold.ttf＆＃39;，115）。这也不起作用。

import pygame
import time
import random
pygame.init
pygame.font.init


display_width = 800
display_height = 600

black = (0,0,0)
white = (255,255,255)
red = (255,0,0)
green = (0,255,0)
blue = (0,0,255)

car_width = 100
car_height = 100

gameDisplay = pygame.display.set_mode((display_width,display_height))
pygame.display.set_caption('A Bit Racey')
clock = pygame.time.Clock()

carImg = pygame.image.load ('racecar.png')
gameOver = pygame.image.load ('gameover.png')

def gO (x,y):
    gameDisplay.blit(gameOver, (x,y))

def things(thingx, thingy, thingw, thingh, color):
    pygame.draw.rect(gameDisplay, color, [thingx, thingy, thingw, thingh])

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

def message_display(text):
    font = pygame.font.SysFont("C:\Windows\Fonts\Arial.ttf", 115)
    TextSurf, TextRect = text_objects(text, font)
    TextRect.center = ((display_width/2), (display_height/2))
    gameDisplay.blit(TextSurf, TextRect)

    time.sleep(2)
    game_loop()

def crash ():
    message_display('Game Over')

def car(x,y):
    gameDisplay.blit(carImg,(x,y))

def game_loop():

    x = (display_width * 0.45)
    y = (display_height * 0.8)

    x_change = 0

    thing_startx = random.randrange(0, display_width)
    thing_starty = -600
    thing_speed = 7
    thing_width = 100
    thing_height = 100

    gameExit = False

    while not gameExit:

                    x_change = 5

            if event.type == pygame.KEYUP:
                if event.key == pygame.K_LEFT or event.key == pygame.K_RIGHT:
                    x_change = 0


        x += x_change

        gameDisplay.fill(white)

        #thingx, thingy, thinkw, thingh, color)
        things(thing_startx, thing_starty, thing_width, thing_height, black)
        thing_starty += thing_speed
        car (x,y)

        if x > display_width - car_width or x < 0:
            crash()


        if thing_starty > display_height:
            thing_starty = 0 - thing_height
            thing_startx = random.randrange(0, display_width)


        if y < thing_starty+thing_height:
            print('y crossover')

            if x > thing_startx and x < thing_startx + thing_width or x+car_width > thing_startx and + car_width < thing_startx+thing_width:
                print('x crossover')
                gO (display_width/2 - 145.5, display_height/2-200)
                time.sleep(2)
                game_loop()


        if gameExit == True:
            pygame.quit()
            quit()


        pygame.display.update()    
        clock.tick(45)

game_loop()
pygame.quit ()
quit ()

Answer 1

您刚才没有在代码段中运行init功能。

# didn't run function
pygame.init
pygame.font.init
# instead
pygame.init()
pygame.font.init()

你的问题很奇怪。真奇怪。它甚至没有任何问题。您没有调用函数pygame.init()。你正在评估它。你正在检查它的存在。如果函数不存在，Python将引发异常但是如果它存在则不会做任何事情。要调用函数，请使用<function_name>(<parameters>)。这个。是。不。红宝石。
