Skill Teaching Equipment & Items
Version: 1.1
Author: modern algebra
Date: February 9, 2008


Version History


  • Version 1.1: Added the feature that you can set skill teaching items to only work on specific actors and classes. 02/09/08
  • Version 1.0: Original release. 01/27/08

Description


This script allows you to assign skills to items, weapons and armors. When assigned to an item, it is possible to permanently learn the skill assigned when the item is used. For weapons and armors, you are able to learn the skill while the weapon or armor is equipped. Once the weapon or armor is unequipped, you will no longer have access to that skill.

Features

  • NEW in v. 1.1 -> You can now make it so that skill teaching items can only teach to specific actors or classes
  • Allows items, weapons, and armors to teach actors skills
  • Very intuitive configuration; it is easy to set up

#  Skill Teaching Equipment & Items
#  Version 1.0
#  Author: modern algebra (rmrk.net)
#  Date: January 27, 2008
#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#  Instructions:
#     Insert this script just above Main. To configure your database, see the
#     Configuration Section at lines 29, 66, and 97 (by default; once you've
#     configured some of the data, this will change)

#  Adds an additional stat, skill_id, to weapons, armors, and items

# ** Item
#==============================================================================

class Item
  #
  attr_sec_reader :skill_id, 'get_stats (0)'
  attr_sec_reader :class_limits, 'get_stats (1)'
  attr_sec_reader :actor_limits, 'get_stats (2)'

  # * Stats

    #~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    # * CONFIGURATION
    #~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    #  It is very easy to configure the database. All that you need to do
    #  is write:
    #
    #     when <item ID>
    #       learn_skill = <skill_id>
    #       class_limits = [<class IDs that can use>]
    #       actor_limits = [<actor IDs that can use>]
    #
    #  For every item that you want to teach skills. To discover what the
    #  ID of an item or a skill is, look at the number directly to the left
    #  of their names in the Database. For the other 2, fill those in
    #  if only specific classes or actors can gain the skill. If you do not
    #  specify, it is assumed that any actor can use the item and gain the
    #  skill. There are two examples below. Feel free to delete them once
    #  you understand what you need to do.
    #~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    when 1 # Potion
      learn_skill = 1 # Heal
      class_limits = [7]
    when 2 # High Potion
      learn_skill = 69 # Poison Edge

This script uses the simple version of Zeriab's attr_sec_reader module addon, included below. It must be inserted into your script editor in order for this script to work.

Code: [Select]
class Module
  def attr_sec_accessor(sym, default = 0)
    attr_writer sym
    attr_sec_reader sym, default
  end
 
  def attr_sec_reader(sym, default = 0)
    sym = sym.id2name
    string = "def #{sym};" +
             "  @#{sym} = #{default}  if @#{sym}.nil?;" +
             "  @#{sym};" +
             "end;"
    module_eval(string)
  end
end

Credit

  • Zeriab, for his attr_sec_reader module addon

Thanks

  • ryu009, for requesting the script

Support


Just post in this topic at rmrk for quick support

Known Compatibility Issues

Should be compatible with any script that does not perform the same function as this one. If any issues arise, I wwill be happy to fix them for you.

Author's Notes


This script was requested by ryu009 (for weapons, at least: I decided to expand upon his request though).

Is there a way to modify this so that you need experiance points to learn the skills. Ok makes no sence...

Right for instance FF9, You needed AP to learn the ability that was attached to the weapon ect.

I know there is a script like that but only on VX

Possible?

Yeah, it's possible. I, however, do not intend to write that extension, at least not anytime soon. I haven't worked in XP for quite some time now, and I think the only script I intend to make are the ones for my own game and version 2 of my Grid Inventory System. So, sorry :(

When tryin to load a previously saved game file I get this when trying to equip/unequip weapons
script "this sript" line 154, NoMethodError occured
undefined method 'include' for nil:NilClass

I get a similiar error further down the script around line 174 for using the items as well.

I mean besides that this script is excellent, and of course i already made a new game with a free shop and what not get to where i was before to continue testing with no issues what so ever. I thought I'd point that out for you. I was trying to edit this last night but my computer died on me.

BTW MA love your scripts, tis a true shame you're mostly done with XP, i would move on to VX if the tileset wasn't so static or has this gotten better?
