#             Transform Enemies based on Variables

#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#  Description:
#
#    This script allows you to use multiple variables to differentiate when
#    an enemy transforms. The usual method is quite heavy on Game Switches if
#    you wish to use it that way, so this alternative has been created.
#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#------------------------------------------------------------------------------
#  Instructions:
#
#     ~  In your Enemy noteboxes input these codes
#           ~TransVarID: ?
#           ~TransReqAmount: ?
#           ~TransNextEnemyID: ?
#           ~TransBattleAnimID: ?
#
#        Replacing the ?'s with a number.
#
#
#         ~TransVarID         = The Variable ID you want to check
#         ~TransReqAmount    = The Required Amount (or above) that the Variable must hold for the conditions to be met
#         ~TransNextEnemyID  = The ID of the enemy you want this enemy to transform into
#         ~TransBattleAnimID = The ID of the Battle Animation you want to see when this enemy transforms (this is not required)
#
