我如何将这个动画移动到玩家的位置？

如何解决我如何将这个动画移动到玩家的位置？

我使用教程制作了此动画，并将其设置为面向右侧的位置以激活动画，但是我尝试将动画移动到玩家位置的所有尝试都失败了。动画需要使用空格键激活，并发生在 onpress[pygame.K_Space]: 函数内。我不太关心代码在哪里。

解决方法

您必须设置 rect 对象的 MySprite 属性的位置。

my_sprite.rect.topleft = (playerX,playerY)

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

前者将 委托给包含的 pygame.sprite.Sprites 的 update 方法 - 您必须实现该方法。见pygame.sprite.Group.update()：

对组中的所有 Sprite 调用 update() 方法 [...]

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

将包含的精灵绘制到 Surface 参数。这对源表面使用 Sprite.image 属性和 Sprite.rect。 [...]
