SKillGem XP
Updated Again!
by Kyonides Arkanthes


Introduction

I had been thinking about skills when I came up with the not so original idea of modifying a skill's stats. This scriptlet would eventually do it via stat modifiers. You better read the comments I included in the script to understand how it actually works! Laughing + Tongue sticking out

Warning!

You will need to parse a TXT file! Happy with a sweat

The Code

Code:
# * SKillGem XP
#   Scripter : Kyonides Arkanthes
#   v0.9.0 - 2019-10-14 (No Custom Scene Menu Included)

# This is the first step of two to let the player modify a hero's skills via
# the consumption of skill gems!

# Create a text file or save the template and name it "skillgem modifiers.txt"
# in your game folder and add as many modifiers as you wish.

# @modifiers.default represents all those skills not defined in the text file
# so modify its default values at will.

# DEBUG Constant values and effects #

# true - parse text file (for games under development)
# false or nil - load rxdata file (for closed demos or finished games)

# * Script Calls * In case you don't want to use the Skill Gem menu

# actor = $game_party.actors[Member_Index]
#   Keeps an actor aka hero in a temporary variable
# actor.skill_level(Skill_ID)
#   Returns a skill's current level
# actor.skill_level_up(Skill_ID)
#   Levels up a skill's level using the brute force method!
#   No skill gems are lost in the process!
# actor.safe_skill_level_up(Skill_ID)
#   Safely levels up a skill's level or returns the current level if failed
#   It consumes skill gems on success!
# actor.enough_skill_gems?(Skill_ID)
#   Checks if there are enough items to level up a skill
#   Returns false if there are no additional levels available!

# $game_party.skill_gems_total
#   Returns the total amount of skill gems the player currently owns.

# * Warning *

# In case you don't include any Title scene script in your game project, REMOVE
# the Scene_Title class contents from my script to prevent your game from
# failing to alias an non existing method. You also need to modify your custom
# script by replacing its own definition of $data_skills with the following:

# $data_skills = SKillGem.skills

module SKillGem
  DEBUG = true
  ITEM_ID = 1 # It should be an item found in the Items Database!
  module Improve

Notes

I might add it has reached some level of maturity so it should not fail to run on fresh projects (with no save files).

I Need Brains!? Confused
No, wait a second! Shocked I just need some Skill Gems! Happy with a sweat 

Today I have revisited this scriptlet to add more features that will make it look usable already! Laughing 

I added skill gem levels to let you ask the player to start collecting skill gems! Tongue sticking out 

Obviously you'll let them level up their skills! Laughing 

You can manually do so via script calls! Laughing + Tongue sticking out

Just promise me you won't EVER dare to level up Aluxes's skills ever! Confused 

I also posted a template so you can use it in your game projects.

Happy Pumped Up Skills! Laughing 

Side notes

I won't be held responsible for overpowering your heroes! Laughing + Tongue sticking out

Important Script Update

I needed to update my script once again because I noticed there could be an issue with editing a game with the default RMXP editor. The root cause was that the editor always tries to read the default RPG::Skill class definition without any later modifications. Saving the new data in the Skills.rxdata file would make the editor crash so I had to add some extra code to save it in a different file, namely SkillsSG.rxdata to make sure you could use vanilla Game.exe or HiddenChest or anything similar and the default editor at any time.

What that also means is that I had to further change other stuff like the Game_Actor class, the class that represents a hero in RM series, to let it fully update the extra skill info I added in my script. The save files will be a little bit larger than before, but that isn't supposed to be a real surprise, don't you think? Laughing 

Don't forget! Happy with a sweat Keep deleting old save files before you update scripts that modify heroes or enemies or vehicles and save such data in binary format! Shocked

By the way, I consider my script has reached the 0.9.0 milestone already, unless you come up with bug reports that force me to fix it. Laughing + Tongue sticking out The only thing that it still lacks would be a menu scene. Laughing
