[XP] Experience Points modifier

[WinterVisage]

This isn't exactly a script request, but this is the only place that I could think of putting it. I've seen it floating around, but couldn't think of what it's name was. Basically, I need a script that removes the pre-defined RMXP experience tables with one that I fully define myself. It doesn't need to be custom to exactly what I'm asking, and if you have one already and are willing to share, that'd be the best.

Thanks for helping!

# Manual Experience Table Enumeration  
# by RPG Advocate
=begin
To create customized xp tables for a character, make a txt document and
devise numbers for the experience.
Note: The numbers you put in are the Total experience for that level.
ie=

0
20
55
125
260

would really be this:

0 xp at level 1
20 xp to level 2
35 xp to level 3
70 xp to level 4
135 xp to level 5

Make sense?
If you don't fill in enough numbers, it will replace the numbers with the
default experience equivelant for that level.
If you put too many levels worth of experience, it will just cut off wherever
you set the max level at.

I think the txt document has to be named 'actor#exp.rxdata', where # is the ID in the database of the actor.

I think the txt document has to be named 'actor#exp.rxdata', where # is the ID in the database of the actor.

Most certainly not. Stick in your script editor. .rxdata files are Marshaled Ruby objects. It wouldn't do a thing saved as one, and if you did add a few lines of code to your game and attempted to load it, you would just raise an Exception.

[Jragyn]

fname = "Data\\actor" + actor.id.to_s + "exp.rxdata"
    if FileTest.exist?(fname)
      get_exp_list_from_file(fname)
      if @exp_file_error
        @exp_list = Array.new(101)
      else
        return
      end

Then what does this mean?
I don't /really/ know, I'm just guessing in an attempt to be useful..
I haven't used this script in a long while. :x

[ForeverZer0]

The script saves/loads data from an external file. It is not really necessary for them to have done this, but the author chose to do it this way. It has absolutely nothing to do with where the script is placed.

Scripts are placed in the editor.

[Jragyn]

How would you have done it then? >.<

[ForeverZer0]

It really doesn't matter either way, but I would have just created a new variable in a class that is already saved, like Game_Party or something. Then you don't need any of the extra saving loading. Its done automatically since the class is already saved by default.

"make a txt document"

Means actor#exp.txt >.> I think... <.< Anyway, thanks for the help! That's exactly the one I was looking for!
