在 pygame 中，重置每个精灵位置的最有效方法是什么？

Question

I'm trying to make a typical platformer using pygame but I'm not exactly sure how I should go about doing a death sequence. I want it so after time the player dies every sprite's position is reset to its original position if they moved at all.

I tried experimenting with the pygame.sprite.Group().copy() but I don't know how to use it or if it even applies to my situation.

Answer 1

I would store a copy of the original position in the sprite, and then as @furas suggests re-position and re-stat the sprite via a reset() function.

For example:

class ResettableSprite( pygame.sprite.Sprite ):
    MAX_HEALTH = 100
    def __init__( self, image, x, y ):
        pygame.sprite.Sprite.__init__( self )
        self.image   = image
        self.rect    = self.image.get_rect()
        self.start_x = x
        self.start_y = y
        self.reset()

    def reset( self ):
        self.rect.x = self.start_x
        self.rect.y = self.start_y
        self.health = ResettableSprite.MAX_HEALTH
        # ... etc.
