#

#  This is a very simple script in principle and intent.  It merely prevents

#  specific status effects  from being added or removed  unless performed by

#  way of a script call.  This way,  custom and unique states that are meant

#  to be permanent  cannot be accidentally healed by way of items of the use

#  of the Recover All map event.

#

#  States that are meant  to be permanent,  and cannot be summarily added or

#  remove by normal means,  have their IDs listed in  the Unalterable_States

#  module below.  There is but only one array to edit.  So... list away!

#

#  As stated earlier, you will now need to use script calls to actively

#  add these states.  They are as follows.

#

#  (target).dvv_add_unalterable_state(state_id [, force] )

#    and

#  (target).dvv_remove_unalterable_state(state_id [, force] )

#

#  EXAMPLE:   $game_party.actors[2].dvv_add_unalterable_state(5)

#

#  These are mirrors of the normal 'add_state' and 'remove_state' methods,

#  the methods which are being bypassed  if an Unalterable state is found.

#  

#

#

#  TERMS AND CONDITIONS:

#  Free for use, even in commercial games.  However, due credit is required.
