Question

代码：

import pygame
pygame.init()
WIDTH = 800
HEIGHT = 480
screen = pygame.display.set_mode((WIDTH,HEIGHT))
block = pygame.sprite.Sprite()
block.image = pygame.image.load('stone.png')
newblock = pygame.transform.scale(block, (64, 64))
newblock.rect = newblock.image.get_rect()
newblock.group = pygame.sprite.GroupSingle(newblock)
newblock.group.draw(screen)
pygame.display.update()

当我尝试使用pygame.transform.scale缩放图像时，它会给我这个错误：

Traceback (most recent call last):
  File "C:/pygame/program.py", line 8, in <module>
    newblock = pygame.transform.scale(block, (64, 64))
TypeError: must be pygame.Surface, not Sprite

Answer 1

错误消息说明了一切。 pygame.transform.scale的第一个参数必须是Surface，但您传递的是Sprite。

我想你想要这样的东西：

import pygame
pygame.init()
WIDTH = 800
HEIGHT = 480
screen = pygame.display.set_mode((WIDTH,HEIGHT))
img = pygame.image.load('stone.png')

block = pygame.sprite.Sprite()
block.image = pygame.transform.scale(img, (64, 64))
block.rect = block.image.get_rect()

group = pygame.sprite.GroupSingle(block)

while True:
    #TODO: event handling
    group.draw(screen)
    pygame.display.update()

缩放Sprite Pygame：必须是pygame.surface
