Sprite:addChild

Available since: Gideros 2011.6

Description

Adds a sprite as a child to this sprite. The child is
added as a last child of this `Sprite` instance.

Sprites can have only one parent. Therefore if you add a child
object that already has a different sprite as a parent,
the sprite is removed from the child list of the other sprite
and then added to this sprite.

= Sprite:addChild(child,)

'child: (Sprite) The child sprite to add. '
