我如何将这个动画移动到玩家的位置？

Question

我使用教程制作了这个动画，并将其设置为如果您面对右侧激活动画，但我所有的尝试移动动画到播放器的位置都失败了。动画需要使用空格键激活，并在onpress[pygame.K_Space]:函数中进行。代码发生在哪里并不是我关心的问题。

您必须设置MySprite对象的rect属性的位置。

my_sprite.rect.topleft = (playerX, playerY)

pygame.sprite.Group.draw()和pygame.sprite.Group.update()是pygame.sprite.Group提供的方法。

前者将委托给所包含的pygame.sprite.Sprites的update方法-您必须实现该方法。请参阅pygame.sprite.Group.update()

在组中的所有Sprite上调用update()方法...

后者使用包含的pygame.sprite.Sprite的image和rect属性来绘制对象-您必须确保pygame.sprite.Sprite具有所需的属性。请参阅pygame.sprite.Group.draw()

将包含的精灵绘制到曲面参数。这将使用源曲面的Sprite.image属性和Sprite.rect。...
