问题描述
我正在尝试从 python 中的类创建一个对象,但出现错误,e_tank = EnemyTank()类型错误:组"对象不可调用"
I am trying to create an object from a class in python but I am getting an Error, "e_tank = EnemyTank()TypeError: 'Group' object is not callable"
我不确定这是什么意思,我试过谷歌,但我无法得到关于导致此错误的明确答案.有谁明白为什么我无法从 EnemyTank 类创建对象?
I am not sure what this means, I have tried Google but I couldn't get a clear answer on what is causing this error. Does anyone understand why I am unable to create an object from my EnemyTank Class?
这是我的代码:
#Image Variables
bg = 'bg.jpg'
bunk = 'bunker.png'
enemytank = 'enemy-tank.png'
#Import Pygame Modules
import pygame, sys
from pygame.locals import *
#Initializing the Screen
pygame.init()
screen = pygame.display.set_mode((640,360), 0, 32)
background = pygame.image.load(bg).convert()
bunker_x, bunker_y = (160,0)
class EnemyTank(pygame.sprite.Sprite):
e_tank = pygame.image.load(enemytank).convert_alpha()
def __init__(self, startpos):
pygame.sprite.Sprite.__init__(self, self.groups)
self.pos = startpos
self.image = EnemyTank.image
self.rect = self.image.get_rect()
def update(self):
self.rect.center = self.pos
class Bunker(pygame.sprite.Sprite):
bunker = pygame.image.load(bunk).convert_alpha()
def __init__(self, startpos):
pygame.spriter.Sprite.__init__(self, self.groups)
self.pos = startpos
self.image = Bunker.image
self.rect = self.image.get_rect()
def getCollisionObjects(self, EnemyTank):
if (EnemyTank not in self._allgroup, False):
return False
self._allgroup.remove(EnemyTank)
result = pygame.sprite.spritecollide(EnemyTank, self._allgroup, False)
self._allgroup.add(EnemyTank)
def update(self):
self.rect.center = self.pos
#Setting Up The Animation
x = 0
clock = pygame.time.Clock()
speed = 250
allgroup = pygame.sprite.Group()
EnemyTank = allgroup
Bunker = allgroup
e_tank = EnemyTank()
bunker = Bunker()5
#Main Loop
while True:
for event in pygame.event.get():
if event.type == QUIT:
pygame.quit()
sys.exit()
screen.blit(background, (0,0))
screen.blit(bunker, (bunker_x, bunker_y))
screen.blit(e_tank, (x, 0))
pygame.display.flip()
#Animation
milli = clock.tick()
seconds = milli/1000.
dm = seconds*speed
x += dm
if x>640:
x=0
#Update the Screen
pygame.display.update()
推荐答案
您已经声明了一个名为 EnemyTank 的类,然后您用以下行覆盖了它:
You've declared a class called EnemyTank and then you've overwritten it with this line:
EnemyTank = allgroup
此后的EnemyTank 不是一个类,而是一个组,不再可调用.你想要做的是:
EnemyTank after this point is not a class, but a group, and no longer callable. What you want to do is:
allgroup pygame.sprite.Group()
e_tank = EnemyTank()
allgroup.add(e_tank)
# Or..
e_tank.add(allgroup)
