Pygame 告诉我图像不是文件对象

如何解决Pygame 告诉我图像不是文件对象

我正在制作一款形状防御游戏，您可以在其中向敌人发射子弹，然后从三角形、方形、五边形等演变。我试图让游戏通过图像显示。但是，当敌人和玩家发生碰撞时，pygame 会给我一个错误，指出 TypeError: not a file object。如何让游戏画面显示？

这是我当前的代码：

import pygame
import random
from pygame.locals import *
from pygame.color import THECOLORS

screen = pygame.display.set_mode((800,600))
pygame.display.set_caption("Shape Defense")


class Sprite(pygame.sprite.Sprite):
    """Base class for all sprites"""

    def __init__(self,window,x,y,image,size=None):
        pygame.sprite.Sprite.__init__(self)

        self.screen = window
        self.x = x
        self.y = y
        self.image = pygame.image.load(image)

        if size is not None:
            self.image = pygame.transform.scale(self.image,size)

        self.rect = self.image.get_rect()
        self.rect.center = (self.x,self.y)

    def update(self):
        self.rect.center = (self.x,self.y)
        self.screen.blit(self.image,self.rect)


class polygon(Sprite):
    """Is it going to be a triangle,a square,a pentagon,or something else?"""

    def __init__(self,sides,size=None):

            self.image = "C:/Users/linpang2018/Desktop/TRASHY JUNK/PICTURES/FOR PYGAME GAMES/triangle.png"

        Sprite.__init__(self,self.window,self.x,self.y,self.image,size)

    def check_for_movement(self,move_amount=1):
        """Let's get moving!"""

        key = pygame.key.get_pressed()

        if key[K_w]:
            self.y -= move_amount
        if key[K_s]:
            self.y += move_amount

        polygon.__init__(self,self.sides,self.screen,size)

    def update(self):
        """Bombs away!"""

        self.y -= 10
        self.rect.center = (self.x,self.y)

        if self.y < 0:
            self.kill()


class Enemy(polygon):

    def __init__(self,size)

解决方法

图像已加载到您的 Sprite 类中：

class Sprite(pygame.sprite.Sprite):
   """Base class for all sprites"""

   def __init__(self,window,x,y,image,size=None):
       # [...]

       self.image = pygame.image.load(image)

因为您必须将文件名传递给 Sprite 类：

class Image(Sprite):
    """Base class for all buttons and images that cover the whole screen"""

    def __init__(self,size=None):
        self.window = window
        self.x = x
        self.y = y
       
        # self.image = pygame.image.load(image) <--- DELETE
        
        filename = image

        Sprite.__init__(self,self.window,self.x,self.y,filename,size)
