Just make sure you do something like I do with my player/camera whenever you move an entity, otherwise you get what I think of as the 'dragging' effect, accentuated by tweening:
;Before moving:
Function GhostOn()
EntityType Player\piv,0
EntityType Camera\hent,0
End Function
;After moving:
Function GhostOff()
EntityType Player\piv,TYPE_PLAYER
EntityType Camera\hent,TYPE_PLAYER
End Function
;Before moving:
Function GhostOn()
EntityType Player\piv,0
EntityType Camera\hent,0
End Function
;After moving:
Function GhostOff()
EntityType Player\piv,TYPE_PLAYER
EntityType Camera\hent,TYPE_PLAYER
End Function
