Blue Magic
Version: 1.1

Introduction
This system allows you to learn skills from enemies when attacked. These learned skills may be exact copies, or may be similar or variations according to what is defined in the script's configuration page. As such, one could let a hero learn the 'Fire' spell if hit with fire or even mass fire.


Script
Blue Magic


Instructions
Fairly easy to use, and the instructions are in the script.


Compatibility
Made specifically for use with RPGMaker XP and the RGSS code. Only needs rewrites or edits for a 'Learning' damage pop as the sample code below shows.


Sample Edit Code
Sample Edits for Damage Pop


Terms and Conditions
Free for use in games both commercial and free. Just give due credit.

This is a pretty sweet script. I wonder if mog has one for his abs o.o

Even tough this has been posted a while back, I wanted to point out a bug. It works all great and fine, exept for this one thing: you can't use heeling spells from the menu anymore. The game will react as if you'd be trying to heal someone who has max health.
The game does not crash or anything, but still I belive this is something that should be brought to attention.

Er...

Le BUMP!
to version 1.1

Rather than utilizing an 'alias' method, I tried using a 'super' class system which didn't work out so well. It's been re-done with the traditional 'alias' system to tell if a skill worked or not. Thanks, yamina-chan for finding it didn't work.

Actually, I'm amazed no one saw the problem for two years it's been out.

Maybe people tested only if the lerning of a new skill would work but did not test it enough to find some bugs?
I couldn't find any in the new version so far, so I'd say good job ^^

It's cause the stack error with f12 since the 'def skill_effect(user, skill)' don't exist on the Game_Actor. (The error happens only when an enemy use an skill after f12 is pressed)

I've made an test using super and got no error:

# INTRODUCTION:
#
#  This system allows you to learn skills from enemies when attacked.   These
#  learned skills may be exact copies, or may be similar or variations accor-
#  ding to what is defined in the script's configuration page.   As such, one
#  could let a hero learn the 'Fire' spell if hit with fire or even mass fire.
#
# . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
#
# LEARNED SKILL VALUE:
#  
#  The system creates a 'learned' value for actor battlers which it can pass
#  into Sprite_Battler and the RPG::Sprite class.  This permits the end user
#  to create a  'Learned'  damage pop showing  if a skill is learned or even
#  what type of skill is learned.  Using such a damage pop is optional.  The
#  value passed (learned) will be the same as the ID value of the skill that
#  is learned, or a value of '0' as a default, non-learned value.
#
#------------------------------------------------------------------------------
#
# CONFIGURABLES:
#
#  There are only three configurables:
#
#  BLUE_MAGIC_IDs:    This is an array that holds the IDs of the actors who
#                     are able to learn skills through being attacked.
#
#  BLUE_TRIGGER:      (optional)  This is a value that identifies a specific
#                     state effect that permits a character to learn through
#                     being attacked.  This is set to 'nil' by default so no
#                     state is required  to learn a skill.   (States such as
#                     Venom, Dizzy, Stun...)
#
#  BLUE_MAGIC_SKILL:  This is a hash array.   It identifies  the skill(s) that
#                     allow your actors to learn skills followed by the actual
#                     learned skill.   This may  differ from  other scripts in
#                     that you can define  one or more  skills that  can teach
#                     a different skill to your actors.
#
#                     The format: = { skill => learned, skill => learned, ... }
#
#==============================================================================



  BLUE_MAGIC_IDs    = [1,2]      # IDs of actors
  BLUE_TRIGGER      = nil         # State that permits skill learning
  BLUE_MAGIC_SKILL  = {7 => 7}    # IDs of skill and skill learned



#==============================================================================
# ** Game_Actor
#------------------------------------------------------------------------------
#  This class handles the actor. It's used within the Game_Actors class
#  ($game_actors) and refers to the Game_Party class ($game_party).
