我正在尝试让演员 "player" 出现在屏幕上（与其他演员一起）并向其添加控件

Question

import pgzero, pygame

#music, sprites and background

music.play("temp.mp3")
x = 0
y = 0

WIDTH = 850
HEIGHT = 425
screen = pygame.display.set_mode((WIDTH, HEIGHT))

title = Actor('title.png')      #calling sprites and saying their pos
title.pos = 400, 212
cont = Actor('cont.png')
cont.pos = 470, 300
player = Actor('ship.png')
player.pos = 100, 56
foe = Actor('foe.png')
foe.pos = 200, 112

def draw():
    screen.clear()
screen.fill((0, 0, 0))
title.draw()
cont.draw()
player.draw()
foe.draw()
vel = 5



#controls
screen.update()

while True:
    player.pos = x, y
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit(); sys.exit()
            main = False

        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_LEFT or event.key == ord('a'):
                print('left')
                x -= vel
            if event.key == pygame.K_RIGHT or event.key == ord('d'):
                print('right')
                x += vel
            if event.key == pygame.K_UP or event.key == ord('w'):
                print('up')
                y += vel
            if event.key == pygame.K_DOWN or event.key == ord('s'):
                print('down')
                y -= vel

        if event.type == pygame.KEYUP:
            if event.key == pygame.K_LEFT or event.key == ord('a'):
                print('left stop')
            if event.key == pygame.K_RIGHT or event.key == ord('d'):
                print('right stop')
            if event.key == pygame.K_UP or event.key == ord('w'):
                print('up stop')
            if event.key == pygame.K_DOWN or event.key == ord('s'):
                print('down stop')
            if event.key == ord('q'):
                pygame.quit()
                sys.exit()
                main = False
screen.update()

我试图让它工作，但我不断收到各种错误，我现在遇到的错误是：AttributeError: 'NoneType' object has no attribute 'blit' 我是编码新手，我觉得它很有趣，但我似乎没有掌握它哈哈。希望你能帮助我解决问题 :D 谢谢！

Indentation in your code is incorrect after screen.clear(). You have to delete the complete while True:-loop. This code will not work with Pygame Zero. It is a Pygame 应用程序和事件循环。 Pygame 零基于 Pygame 但不一样。您不能使用 Pygame 零，而是 Pygame 的事件处理。注意 draw 在后台连续调用。 draw 是“应用程序循环”。

一个工作示例可能如下所示：

import pgzrun
import pygame

WIDTH = 850
HEIGHT = 425

title = Actor('title.png')      #calling sprites and saying their pos
title.pos = 400, 212
cont = Actor('cont.png')
cont.pos = 470, 300
player = Actor('ship.png')
player.pos = 100, 56
foe = Actor('foe.png')
foe.pos = 200, 112
vel = 5

music.play("temp.mp3")

def draw():
    screen.clear()
    screen.fill((0, 0, 0))
    title.draw()
    cont.draw()
    player.draw()
    foe.draw()

def update():
    keys = pygame.key.get_pressed()
    x, y = player.pos
    x += (keys[pygame.K_d] - keys[pygame.K_a]) * vel
    y += (keys[pygame.K_s] - keys[pygame.K_w]) * vel
    player.pos = x, y

pgzrun.go()

i am trying to make the actor "player" show on screen (along with the other actors) and add controls to it

python

pygame

controls
