如何在Pygame中正确加载图像?

每当我尝试加载一些薯条(游戏中的敌人)的图像时,它都会加载精灵。我认为图像是空白的。如何正确加载图像以使其显示?

我试图更改加载图像的方法,选择从类的外部而不是内部加载图像。

import pygame
pygame.init()
# how big the game window is
wind = pygame.display.set_mode((600,700))

pygame.display.set_caption("Heart Attack")

x = 50
y = 50
width = 40
height = 60
vel = 0.8

fries = pygame.image.load('enemy.png').convert_alpha()

class Enemy(pygame.sprite.Sprite):
    def __init__(self, pos):
        super().__init__()
        self.image = fries
        self.rect = self.image.get_rect(center = pos)

move = True
Enemy((100, 300))

while move:
    pygame.time.delay(1)
#kill switch
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            move = False
    keys = pygame.key.get_pressed()
#moves character
    if keys[pygame.K_LEFT]:
        x -= vel
    if keys[pygame.K_RIGHT]:
        x += vel
    if keys[pygame.K_UP]:
        y -= vel
    if keys[pygame.K_DOWN]:
        y += vel
 # makes the character not clone itself
    wind.fill((0,0,0))      
 # draws and displays character with the color red
    pygame.draw.rect(wind, (255, 0, 0), (x, y, width, height))
    pygame.display.update()

pygame.quit()

我需要显示精灵,但它显示为空白。我希望它在屏幕中间生成,因此在center = pos中出现。

图像可能已加载好;但实际上您从未将它涂抹到屏幕表面。

您可以将代码更改为此:

...
sprites = pygame.sprite.Group(Enemy((100, 300)))

move = True
while move:
...
    sprites.draw(wind)
    pygame.display.update()

使用Group,这是pygame绘制精灵的默认方式。
