我有一个列表，其中包含的类，enemy并且已使它们for在敌人类中使用循环和一个函数跟随玩家跟随玩家move()。
但是，当有多个敌人时，他们会随着玩家而混乱，因此我决定将其添加到for循环中：
for enmy in enemies:
pygame.draw.circle(screen, (255,0,0), (enmy.x-enmy.rad,enmy.y-enmy.rad), enmy.rad, 0)
for enmy2 in enemies:
if enmy2 is not enmy:
if not enmy.rect.colliderect(enmy2.rect):
enmy.move()
enmy.rect=pygame.Rect(enmy.x-enmy.rad*2,enmy.y-enmy.rad*2,enmy.rad*2,enmy.rad*2)
pygame.draw.rect(screen, (0,0,255), enmy.rect, 2)
因此，我希望这将对列表中除自身之外的每个实例进行测试，但是当对象单独存在时，它不会移动！（而且如果其中有两个，它们会碰撞并停下来）
这是完整的代码（不需要额外的文件c :）
import pygame
from random import randint
from pygame.locals import *
pygame.init()
screen=pygame.display.set_mode((640,480))
clock=pygame.time.Clock()
px=35
py=35
prect=pygame.Rect(px-10,py-10,20,20)
class Enemy(object):
def __init__(self,x,y):
self.x=x
self.y=y
self.rad=randint(5,10)
self.rect=pygame.Rect(0,0,0,0)
def move(self):
if self.x>px:
self.x-=1
if self.y<py:
self.y+=1
if self.x<px:
self.x+=1

self.y-=1
enemies=[Enemy(90,80),Enemy(100,100)]
while True:
screen.fill((200,230,200))
key=pygame.key.get_pressed()
if key[K_UP]:
py-=2
if key[K_DOWN]:
py+=2
if key[K_RIGHT]:
px+=2
if key[K_LEFT]:
px-=2
for e in pygame.event.get():
if e.type==QUIT:
exit()
for enmy in enemies:
pygame.draw.circle(screen, (255,0,0), (enmy.x-enmy.rad,enmy.y-enmy.rad), enmy.rad, 0)
for enmy2 in enemies:
if enmy2 is not enmy:
if not enmy.rect.colliderect(enmy2.rect):
enmy.move()
enmy.rect=pygame.Rect(enmy.x-enmy.rad*2,enmy.y-enmy.rad*2,enmy.rad*2,enmy.rad*2)
pygame.draw.rect(screen, (0,0,255), enmy.rect, 2)
prect=pygame.Rect(px-20,py-20,20,20)
pygame.draw.circle(screen, (0,0,255), (px-10,py-10), 10, 0)
pygame.draw.rect(screen, (255,0,0), prect, 2)
clock.tick(80)
pygame.display.flip()
有人请帮助我！
经过深思熟虑并摆弄（也玩），我设法做到了以下几点...
