# ** Enemies Use Items

#------------------------------------------------------------------------------

#    by Fomar0153

#    updates by DerVVulfman

#    version 2.1

#       12-02-2007

#    Full SDK 2.3 Compatible (Does not need or require SDK 2.3)

#------------------------------------------------------------------------------

#

# INTRODUCTION:

#

# This system allows enemy battlers to use items during battle.  This is accom-

# plished by switching the skill used by an enemy to that of an item in a pre-

# defined list in the configuration section.

#

# By example, you could set up a Skeleton enemy to use a 'Tonic' in battle when

# it performs its 'Sleep' skill.   This 'skill-to-item' change would have to be

# defined in either the SWITCH_SKILL_ITEM hash,  or the SWITCH_ENEMY_SKILL_ITEM 

# hash (explained in the configuration section below).

#

# The enemies can either have infinite item usage, or can be limited to the no.

# of items used based on the SP points at their disposal.  This feature is con-

# trolled by the SWITCH_SP_LIMIT value. As long as it is false, enemies can use

# items without running out.   But if it is true, the enemies will use up their

# SP points as they use items.  The SP points used will be based on the SP Cost

# of the Skill it is switched from.

#

#------------------------------------------------------------------------------

#

# COMPATABILITY:

#

# This system is compatible  with the default battlesystem,  SDK 2.2,  the RTAB

# system,  Fomar's Action Cost,  ParaDog's  and XRXS's battle system in certain

# limits.

#

# Systems that  use AT bars  (everything except the 'default' and 'SDK default' 

# battlesystems) must have the SWITCH_SP_LIMIT value set to 'false'.  All other

# systems either use up the enemy sp  through repeated calls of the make_action

# def as their AT gauges are filled, or uses values other than sp_cost.

#

# In short,  the 'SWITCH_SP_LIMIT' value can only be 'true' if you're using the

# default or SDK default battlesystems.

# This constant holds the list of skills and items they are switched with.  It

# is in the following format:  { skill.id => item.id, skill.id => item.id,... }

# The sample currently switches the "Heal" skill with the "Sharp Stone" item, 

# and the "Greater Heal" with the "Potion" item.

  SWITCH_SKILL_ITEM       = {1 => 1, 2 => 1}

# This constant holds the lists of skills & items switched  for each enemy that

# uses them. The format to apply the switch mimics the design to the one above:

# { enemy.id => ( skill.id => item.id), enemy.id =>{ skill.id => item.id},... }

# The sample currently switches the "Mass Heal" skill with the "Tonic" item for

# the GHOST enemy,  and changes the "Heal" skill  with the "Barrier Stone" item

# for the BASILISK enemy.

  SWITCH_ENEMY_SKILL_ITEM = { 1 => {3 => 1}, 2 => {1 => 1}}

# This merely determines if you limit the items based on Skill SP cost. If this

# is true,  then the enemy must have enough SP to use the original skill before

# the item is used.  If it is false, then the enemy has an infinite supply.
