Introduction

After awhile of searching through script databases, I was unsuccessful at finding a class changing script that did what I wanted it to do. I found one that was sort of close, but didn't work with BlizzABS, or any other ABS for that matter, and that just didn't work for me. So, I decided to make one, and I think it turned out quite well. The system is reminiscent of Final Fantasy Tactics Advanced.
Features
  • *Simple configuration*Customizable class requirements*Optional graphic changing upon class change*Descriptions for each class

Script

   # VERY IMPORTANT NOTES:
   #
   # For every minor update or bugfix, I will increase the version by .01
   # For every new feature, I will increase the version be .1
   # For every 10 feature updates, I will update the version by 1
   #
   # Compatibility:
   #
   # The script was coded to be 100% compatible with most, if not all scripts. I can't
   # think of ANY script that wouldn't be compatible, but I will list those that I
   # tested for compatibility.
   #
   # Blizz ABS is 100% compatible, and most ABS scripts should be as well, due to how
   # the class rank is added.
   #
   # CCoa's UMS is 100% compatible.
   #
   # The SDK 2.3 seemed to be compatible. Everything worked fine even with the SDK
   # in the project.
   #
   # I'll keep testing scripts, and adding to this list
   #
   # Incompatibility:
   #
   # No known incompatibility
   #
   #
   # Known Issues:
   #
   # none ^_^
   #
   # Features:
   #
   # The Legacy Class Change system allows you to define how many levelups with a
   # certain class or classes are needed to unlock another class. Its setup in such
   # a way to fit ANY game's needs. You can also define a description for the class
   # or just set the description for each class to what type of class (long range,
   # close range, magical, popcorn wielding, ect.) It's done in such a way that you
   # can configure it to work with whatever style of RPG your making, whether it be
   # serious, joke, abs, turn based, tbs, or any other kind of RPG, the Legacy Class
   # Change will work for your game.
   #
   # Another of the newer features is the ability to have the actor's graphic (both
   # charset AND battler) change when the class is changed. This can be disabled,
   # or configured so that only certain classes will cause a graphic change, or that
   # certain classes share a graphic. I know that every game has different needs, so
   # I make my scripts as flexible as possible
   #
   # And you know what the best part is? I'm constantly working on adding new
   # features, and making Legacy Class Change work even better.
   #
   # Version History:
   #
   # v1.00b:
   #   -> Legacy Class Change released!
   #
   # v1.01b:
   #   -> Fixed a bug in class selection, that would set the actor's class_id to the
   #      index of the cursor, rather than the actual selected class_id.
   #
   # v1.02b:
   #   -> Fixed a few miscellaneous lines of code that could, under certain circumstances, cause errors
   #
   # v1.10b:
   #   -> Added the option to change an actor's graphic when the class changes.
   #
   # v1.10b:
   #   -> Fixed a bug that kept the class list from scrolling
   #
   # v.1.20:
   #   -> Left the beta stage.
   #   -> Enhanced the level handeling. Now the skills are assigned based on class
   #      level, rather than the actor's overall level.
   #
   #
   # Useless facts:
   #
   # This was the first time I've ever successfully made a script. I learned a lot
   # about everything I worked with, and can't wait to learn more about RGSS and
   # programming in general. I hope you enjoy this, because it cost an entire BOX
   # of trisquites, and a couple gallons of milk to make.
   #
   # Special Thanks:
   #
   #       - Blizzard for all his help. Without him, I couldn't have made it. Not
   #         only did he help me fix the errors, he also gave me lectures on various
   #         aspects of programming. This caused me to make LESS errors, and grow
   #         in my programming skill. Thanks blizz, this script wouldn't be here
   #         today if you hadn't been there in that MIRC room, XD
   #
   #       - GubiD for when blizzard wasn't around in MIRC to answer my questions.
   #         he helped me with a few errors that I had no idea how to fix (many of
   #         them were some of the most n00bish errors too -_-). Thanks GubiD
   #         couldn't have done it without ya!
   #
   #      - Sephirothtds for making TDS Class Change System incompatible with
   #        the Blizz-ABS. If you'd made it compatible, I would have gone with your
   #        script, and never figured out how to make one myself (a much easier to
   #        configure one at that). Your script's incompatibility sparked my urge to
   #        learn to scrip. Thanks.
   #
   #       - Juan, who offered a few pointers.
   #
   #       - To all those who put up with me in the CP chat room when I'm ranting
   #         about my newest error.
   #
   #       - To all the members of eminweb.com for nagging me enough to do my
   #         administrative duty, which eventually cured me of my infamous laziness
   #
   #       - StarrodKirby86 for requesting the class graphic system, it made this
   #         script have a feature not many class changing systems have.

Instructions

Instructions are in the script


Compatibility

100% compatible with the SDK (or so it seems)

100% compatible with Ccoa's UMS

100% compatible with the BlizzABS

Should be 100% compatible with most scripts.

Credits and Thanks
  • *Blizzard for all his help. Without him, I couldn't have made it. Notonly did he help me fix the errors, he also gave me lectures on variousaspects of programming. This caused me to make LESS errors, and growin my programming skill. Thanks blizz, this script wouldn't be heretoday if you hadn't been there in that MIRC room, XD*GubiD for when blizzard wasn't around in MIRC to answer my questions.he helped me with a few errors that I had no idea how to fix (many ofthem were some of the most n00bish errors too -_-). Thanks GubiDcouldn't have done it without ya!*Sephirothtds for making TDS Class Change System incompatible withthe Blizz-ABS. If you'd made it compatible, I would have gone with yourscript, and never figured out how to make one myself (a much easier toconfigure one at that). Your script's incompatibility sparked my urge tolearn to scrip. Thanks.*Juan, who offered a few pointers.*To all those who put up with me in the CP chat room when I'm rantingabout my newest error.*To all the members of eminweb.com for nagging me enough to do myadministrative duty, which eventually cured me of my infamous laziness*StarrodKirby86 for requesting the class graphic system, it made thisscript have a feature not many class changing systems have.


Author's Notes

I'm working on adding a few more features. Please give me some suggestions!
