--For usage, check out the encounter Lua's EncounterStarting() and Update() functions.

-- First, we can create the torso, legs and head.
sanstorso = CreateSprite("sans/sanstorso")
sanslegs = CreateSprite("sans/sanslegs")
sanshead = CreateSprite("sans/sanshead2_noglasses")
glasses = CreateSprite("sans/sansglasses")

--We parent the torso to the legs, so when you move the legs, the torso moves too.
--We do the same for attaching the head to the torso.
sanstorso.SetParent(sanslegs)
sanshead.SetParent(sanstorso)
glasses.SetParent(sanshead)

--Now we adjust the height for the individual parts so they look more like a skeleton and less like a pile of bones.
sanslegs.y = 240
sanslegs.x = 320
sanstorso.y = -5 --The torso's height is relative to the legs they're parented to.
sanshead.x = 0 --The head's height is relative to the torso it's parented to.
sanshead.y = -50 --The head's height is relative to the torso it's parented to.

--We set the torso's pivot point to halfway horizontally, and on the bottom vertically,
--so we can rotate it around the bottom instead of the center.
sanstorso.SetPivot(0.5, 0)

--We set the torso's anchor point to the top center. Because the legs are pivoted on the bottom (so rescaling them only makes them move up),
--we want the torso to move along upwards with them.
sanstorso.SetAnchor(0.5, 0.5)
sanslegs.SetPivot(0.5, 0)
