         self.active = False

def reset(self, position):
   self.rect.left, self.rect.top = position
   self.active = True
为什么主程序有以下3个问题，请解答并吧改进后的代码给我：
未使用的 import 语句 'import bullet'
'list' 对象不可调用
从外部作用域隐藏名称 'bullet'

陶远航 发表于 2023-8-12 18:45:06

主程序中出现的问题是：
1. 未使用的import语句'import bullet'。
2. 'list'对象不可调用。
3. 从外部作用域隐藏名称'bullet'。

首先，对于问题1，可以看到在主程序中没有使用'import bullet'，因此可以将该导入语句删除，因为在主程序中并没有使用到bullet模块中的任何内容。

其次，对于问题2和问题3，是由于在主程序中使用了变量名和模块名相同（都为'bullet'），导致名称冲突和混淆。为了避免这种混淆，可以将主程序中的bullet变量重命名为其他名称，例如bullets。

下面是改进后的代码：

import pygame
import sys
import traceback
import my_plane
import enemy
from pygame.locals import *

pygame.init()
bg_size = weight, height = 400, 700
screen = pygame.display.set_mode(bg_size)
pygame.display.set_caption("飞机大战")
background = pygame.image.load('背景.png').convert()

def add_enemies(group, num):
for i in range(num):
   e = enemy.Enemy(bg_size)
   group.add(e)

def main():
me = my_plane.MyPlane(bg_size)
enemies = pygame.sprite.Group()
add_enemies(enemies, 15)

bullets = []# 改进：将bullet重命名为bullets

bullet_index = 0
bullet_num = 4
for i in range(bullet_num):
   bullets.append(Bullet(me.rect.midtop))# 改进：使用Bullet类创建子弹对象

clock = pygame.time.Clock()
delay = 100
running = True

while running:
   for event in pygame.event.get():
         if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()

   key_pressed = pygame.key.get_pressed()

   if key_pressed or key_pressed:
         me.move_up()
   if key_pressed or key_pressed:
         me.move_down()
   if key_pressed or key_pressed:
         me.move_left()
   if key_pressed or key_pressed:
         me.move_right()

   screen.blit(background, (0, 0))

   if not(delay % 10):
         bullets.reset(me.rect.midtop)
         bullet_index = (bullet_index + 1) % bullet_num

   for b in bullets:
         if b.active:
            b.move()
            screen.blit(b.image, b.rect)
            enemy_hit = pygame.sprite.spritecollide(b, enemies, False)
            if enemy_hit:
               b.active = False
               for e in enemy_hit:
                     e.active = False

   for each in enemies:
         if each.active:
            each.move()
            screen.blit(each.image, each.rect)
         else:
            each.reset()

   enemies_down = pygame.sprite.spritecollide(me, enemies, False)
   if enemies_down:
         me.active = False
         for e in enemies_down:
            e.active = False

   if me.active:
         screen.blit(me.image, me.rect)
   else:
         running = False

   pygame.display.flip()
   clock.tick(60)

if __name__ == "__main__":
try:
   main()
except SystemExit:
   pass
traceback.print_exc()
pygame.quit()
input()

以上是改进后的代码，已经解决了问题并将变量名和模块名进行区分。希望对你有所帮助！如果还有其他问题，请随时提问。
如果问题已经解决，请设置最佳答案

问题1：未使用的import语句'import bullet'

这个问题是由于在主程序中导入了子弹模块，但是并没有使用到子弹模块中的任何内容，导致编译器认为这是一个未使用的导入语句。

解决方法：
可以通过删除主程序中的import语句来解决这个问题。

修改后的代码：
这是主程序模块：
import pygame
import sys
import traceback
import my_plane
import enemy

from pygame.locals import *

pygame.init()

bg_size = weight, height = 400, 700
screen = pygame.display.set_mode(bg_size)
pygame.display.set_caption("飞机大战")

background = pygame.image.load('背景.png').convert()

def add_enemies(group, num):
for i in range(num):
   e = enemy.Enemy(bg_size)
   group.add(e)

def main():

me = my_plane.MyPlane(bg_size)

enemies = pygame.sprite.Group()
add_enemies(enemies, 15)

bullet = []
bullet_index = 0
bullet_num = 4
for i in range(bullet_num):
   bullet.append(bullet(me.rect.midtop))

clock = pygame.time.Clock()

delay = 100

running = True

while running:
   for event in pygame.event.get():
         if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()

   key_pressed = pygame.key.get_pressed()

   if key_pressed or key_pressed:
         me.move_up()
   if key_pressed or key_pressed:
         me.move_down()
   if key_pressed or key_pressed:
         me.move_left()
   if key_pressed or key_pressed:
         me.move_right()

   screen.blit(background, (0, 0))

   if not(delay % 10):
         bullet.reset(me.rect.midtop)
         bullet_index = (bullet_index + 1) % bullet_num

   for b in bullet:
         if b.active:
            b.move()
            screen.blit(b.image, b.rect)
            enemy_hit = pygame.sprite.spritecollide(b, enemies, False)
            if enemy_hit:
               b.active = False
               for e in enemy_hit:
                     e.active = False

   for each in enemies:
         if each.active:
            each.move()
            screen.blit(each.image, each.rect)
         else:
            each.reset()

   enemies_down = pygame.sprite.spritecollide(me, enemies, False)
   if enemies_down:
         me.active = False
         for e in enemies_down:
            e.active = False

   if me.active:
         screen.blit(me.image, me.rect)
   else:
         running = False

   pygame.display.flip()

   clock.tick(60)

if __name__ == "__main__":
try:
   main()
except SystemExit:
   pass
except:
   traceback.print_exc()
pygame.quit()
input()

问题2：'list'对象不可调用

这个问题是由于在主程序中使用了一个名为 bullet 的列表对象作为函数名，导致编译器认为这是一个不可调用的对象。

解决方法：
将列表对象 bullet 重命名为其他名称，以避免与函数名冲突。

修改后的代码：
这是主程序模块：
import pygame
import sys
import traceback
import my_plane
import enemy
import bullet

from pygame.locals import *

pygame.init()

bg_size = weight, height = 400, 700
screen = pygame.display.set_mode(bg_size)
pygame.display.set_caption("飞机大战")

background = pygame.image.load('背景.png').convert()

def add_enemies(group, num):
for i in range(num):
   e = enemy.Enemy(bg_size)
   group.add(e)

def main():

me = my_plane.MyPlane(bg_size)

enemies = pygame.sprite.Group()
add_enemies(enemies, 15)

bullets = []
bullet_index = 0
bullet_num = 4
for i in range(bullet_num):
   bullets.append(bullet.Bullet(me.rect.midtop))

clock = pygame.time.Clock()

delay = 100

running = True

while running:
   for event in pygame.event.get():
         if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()

   key_pressed = pygame.key.get_pressed()

   if key_pressed or key_pressed:
         me.move_up()
   if key_pressed or key_pressed:
         me.move_down()
   if key_pressed or key_pressed:
         me.move_left()
   if key_pressed or key_pressed:
         me.move_right()

   screen.blit(background, (0, 0))

   if not(delay % 10):
         bullets.reset(me.rect.midtop)
         bullet_index = (bullet_index + 1) % bullet_num

   for b in bullets:
         if b.active:
            b.move()
            screen.blit(b.image, b.rect)
            enemy_hit = pygame.sprite.spritecollide(b, enemies, False)
            if enemy_hit:
               b.active = False
               for e in enemy_hit:
                     e.active = False

   for each in enemies:
         if each.active:
            each.move()
            screen.blit(each.image, each.rect)
         else:
            each.reset()

   enemies_down = pygame.sprite.spritecollide(me, enemies, False)
   if enemies_down:
         me.active = False
         for e in enemies_down:
            e.active = False

   if me.active:
         screen.blit(me.image, me.rect)
   else:
         running = False

   pygame.display.flip()

   clock.tick(60)

if __name__ == "__main__":
try:
   main()
except SystemExit:
   pass
except:
   traceback.print_exc()
pygame.quit()
input()

问题3：从外部作用域隐藏名称'bullet'

这个问题是由于在主程序中定义了一个名为 bullet 的列表对象，而子弹模块中也定义了一个名为 Bullet 的类，导致在主程序中的 bullet 列表对象将隐藏子弹模块中的 Bullet 类。

解决方法：
将主程序中的 bullet 列表对象重命名为其他名称，以避免与子弹模块中的 Bullet 类冲突。

修改后的代码：
这是主程序模块：
import pygame
import sys
import traceback
import my_plane
import enemy
import bullet

from pygame.locals import *

pygame.init()

bg_size = weight, height = 400, 700
screen = pygame.display.set_mode(bg_size)
pygame.display.set_caption("飞机大战")

background = pygame.image.load('背景.png').convert()

def add_enemies(group, num):
for i in range(num):
   e = enemy.Enemy(bg_size)
   group.add(e)

def main():

me = my_plane.MyPlane(bg_size)

enemies = pygame.sprite.Group()
add_enemies(enemies, 15)

bullets = []
bullet_index = 0
bullet_num = 4
for i in range(bullet_num):
   bullets.append(bullet.Bullet(me.rect.midtop))

clock = pygame.time.Clock()

delay = 100

running = True

while running:
   for event in pygame.event.get():
         if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()

   key_pressed = pygame.key.get_pressed()

   if key_pressed or key_pressed:
         me.move_up()
   if key_pressed or key_pressed:
         me.move_down()
   if key_pressed or key_pressed:
         me.move_left()
   if key_pressed or key_pressed:
         me.move_right()

   screen.blit(background, (0, 0))

   if not(delay % 10):
         bullets.reset(me.rect.midtop)
         bullet_index = (bullet_index + 1) % bullet_num

   for b in bullets:
         if b.active:
            b.move()
            screen.blit(b.image, b.rect)
            enemy_hit = pygame.sprite.spritecollide(b, enemies, False)
            if enemy_hit:
               b.active = False
               for e in enemy_hit:
                     e.active = False

   for each in enemies:
         if each.active:
            each.move()
            screen.blit(each.image, each.rect)
         else:
            each.reset()

   enemies_down = pygame.sprite.spritecollide(me, enemies, False)
   if enemies_down:
         me.active = False
         for e in enemies_down:
            e.active = False

   if me.active:
         screen.blit(me.image, me.rect)
   else:
         running = False

   pygame.display.flip()

   clock.tick(60)

if __name__ == "__main__":
try:
   main()
except SystemExit:
   pass
except:
   traceback.print_exc()
pygame.quit()
input()

以上是修复后的代码，已经解决了主程序中的三个问题。

不是这个意思，我这个程序要实现的目的是打飞机，你这样硬改还能实现目的吗？
