#    Visible Injuries
#    Version: 1.0.0

#++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
#  Description:
#
#    This script allows you to set it so that an enemy's battler will change
#   when the enemy falls below any percentage of HP you choose. This can be
#   used to make it so that the battler looks like it gets progressively
#   more injured throughout the battle.
#++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
#  Instructions:
#
#    Paste this script into its own slot in the Script Editor, above Main but
#   below Materials.
#
#    To set which battlers should be used to reflect injury and at what
#   percentage of health, you use the following code in the enemy's note field:
#
#        \injured_battler[p, "b", h]
#
#    where:  p - an integer between 1 and 100; this is the percentage of HP
#           the enemy must fall below before the battler is changed.
#            b - the filename of the battler
#            h - the hue of the battler. If not included, defaults to 0.
#
#  EXAMPLE:
#
#    If the following is in an Slime's note field:
#
#        \injured_battler[50, "Slime", 128]
#
#    Then when the Slime falls below 50% HP, it will change hue to 128.
#
#    If the following is in a Bandit's note field:
#
#        \injured_battler[70, "Injured Bandit"]
#        \injured_battler[25, "Wounded Bandit"]
#
#    Then when the Bandit falls below 70% HP, the battler graphic will change
#   to "Injured Bandit". When the Bandit falls below 25% HP, the battler
#   graphic will change to "Wounded Bandit".
