Pygame不会blit图像列表

Question

我开始用pygame用python构建一个简单的窗口，以遍历图像列表并对其进行blit

import pygame

pygame.init()

Window = pygame.display.set_mode((800, 600))
bg = pygame.image.load("/Users/luke.redwine/Documents/Python/PyGame/Examples/pygame lesson spaceinvaders/space.jpg")
clock = pygame.time.Clock()

animateNeutral = [pygame.image.load("/Users/luke.redwine/Documents/Python/PyGame/Space Shooter Game/Plasma T Neutral %s.png"% frame)for frame in range (1,3)] 
animateFiring = [pygame.image.load("/Users/luke.redwine/Documents/Python/PyGame/Space Shooter Game/plasma T fire %s.png"% frame)for frame in range (1,7)]

running = True
while running:
    events = pygame.event.get()
    keys = pygame.key.get_pressed()
    for event in events:             
        if event.type==pygame.QUIT or keys[pygame.K_ESCAPE]:
            pygame.quit()

    Window.blit(bg, (0,0))
    clock.tick(10)
    Window.blit(animateNeutral)
    Window.blit(animateFiring)
pygame.quit()

我试着快速制作它，这样我就可以看到它的动画效果，但它抛出了这个错误：

 Traceback (most recent call last):
  File "/Users/luke.redwine/Documents/Python/PyGame/Space Shooter Game/space rpg.py", line 22, in <module>
    Window.blit(animateNeutral)
TypeError: argument 1 must be pygame.Surface, not list

blit函数需要一个曲面参数

您可以使用内置的itertools.cycle来创建一个生成器，该生成器将永远在图像中循环

以下是基于您的示例的一些未经测试的代码：

import itertools
import pygame
pygame.init()

Window = pygame.display.set_mode((800, 600))
bg = pygame.image.load("/Users/luke.redwine/Documents/Python/PyGame/Examples/pygame lesson spaceinvaders/space.jpg")
clock = pygame.time.Clock()

animateNeutral = [pygame.image.load("/Users/luke.redwine/Documents/Python/PyGame/Space Shooter Game/Plasma T Neutral %s.png"% frame)for frame in range (1,3)] 
animateFiring = [pygame.image.load("/Users/luke.redwine/Documents/Python/PyGame/Space Shooter Game/plasma T fire %s.png"% frame)for frame in range (1,7)]

neutral_animations = itertools.cycle(animateNeutral)
firing_animations = itertools.cycle(animateFiring)

neutral_dest = (50, 50)
firing_dest = (200, 50)

running = True
while running:
    events = pygame.event.get()
    keys = pygame.key.get_pressed()
    for event in events:             
        if event.type==pygame.QUIT or keys[pygame.K_ESCAPE]:
            pygame.quit()

    Window.blit(bg, (0,0))
    clock.tick(10)
    Window.blit(next(neutral_animations), neutral_dest)
    Window.blit(next(firing_animations), firing_dest)
pygame.quit()

或者，您可以手动跟踪当前动画帧的索引，每帧递增一次，然后重置一次，使其大于列表的长度

编辑：根据surface.blit()的要求添加目的地

一定要查看上面的链接，获取一些文档，但是可能很难找到答案

回答 如果您试图按顺序执行blit，请尝试使用blit

为了

animateNeutral = [pygame.image.load("/Users/luke.redwine/Documents/Python/PyGame/Space Shooter Game/Plasma T Neutral %s.png"% frame)for frame in range (1,3)] 
animateFiring = [pygame.image.load("/Users/luke.redwine/Documents/Python/PyGame/Space Shooter Game/plasma T fire %s.png"% frame)for frame in range (1,7)]

这是一个图像列表，blits（）获取一系列曲面（在您的示例中为图像） 如果要使用多个精灵，则应考虑转换曲面，如果曲面具有透明度（alpha），请使用convert_alpha（）
