Pygame Player精灵错误:未定义名称“Player”[重复]

game-development pygame class python

Ballo Adam · 技术社区 · 7 年前

我有两个文件: sprites.py 和 test.py . 在里面 精灵。py公司 ,我做了一个 Player main 文件( )使用 from player import * .

精灵。py公司 :

import pygame
from test import *

class Player(pygame.sprite.Sprite):
    # ...
    pass

测验py公司 :

import pygame
from sprites import *

# ...

all_sprites = pygame.sprite.Group()
player = Player()                       #  <-- line 28,Â NameError
all_sprites.add(player)

我发现这个错误:

Traceback (most recent call last):
  File "test.py", line 2, in <module>
    from sprites import *
  File "C:\Users\Adam\Desktop\PYthon Test\sprites.py", line 2, in <module>
    from test import *
  File "C:\Users\Adam\Desktop\PYthon Test\test.py", line 28, in <module>
    player = Player()
NameError: name 'Player' is not defined

我已经确保所有内容拼写正确。这个错误是从哪里来的?

问题是 from test import * 在里面 sprite.py -有时会出现问题的循环输入

我的版本和一些其他修改。

import pygame
from sprites import *

# --- constants --- (UPPER_CASE_NAMES)

WHITE = (255,255,255)
BLACK = (0,0,0)

WIDTH = 900
HEIGHT = 450

# --- main ---

# - init -

pygame.init()
#pygame.mixer.init() # pygame.init() should init mixer too
screen = pygame.display.set_mode((WIDTH,HEIGHT))
pygame.display.set_caption('game')

# - objects -

all_sprites = pygame.sprite.Group()
player = Player()
all_sprites.add(player)

# - mainloop -

clock = pygame.time.Clock()
running = True

while running:

    # - events -

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_ESCAPE:
                running = False
        player.handle_event(event)

    # - updates - 

    all_sprites.update()

    # - draw -

    screen.fill(WHITE)
    all_sprites.draw(screen)
    pygame.display.flip()

    # - FPS -

    clock.tick(30)

# - end -

pygame.quit()
