Enemy Stat Variance

Enemy Stat Variance
Version: 1.1
Author: modern algebra
Date: September 26, 2008

Version History

• <Version 1.1> 09/26/08 Added the ability to use random percentile
• <Version 1.0> 09/08/08 Original Release

Description

This script allows you to attach a variance to each enemy stat, so that enemy instances aren't all just clones of each other but can have stat differences.

Features

• Enemies of the same type aren't just clones of each other.
• Allows you to set variance for each of the stats of each enemy individually
• Allows you to use percentile increase in addition to definite numbers
• Intuitive configuration

#  Enemy Stat Variance
#  Version: 1.1
#  Author: modern algebra
#  Date: September 26, 2008
#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#  Instructions:
#    Just place the code for each of the stat variances you want into the notes
#   box of the Enemy. The possible codes are:
#  
#      \variance_hp[x]
#      \variance_mp[x]
#      \variance_atk[x]
#      \variance_def[x]
#      \variance_spi[x]
#      \variance_agi[x]
#      \variance_hp%[x]
#      \variance_mp%[x]
#      \variance_atk%[x]
#      \variance_def%[x]
#      \variance_spi%[x]
#      \variance_agi%[x]
#
#    Each of the codes will give a variance of x to the stat chosen. A variance
#   x means that the enemy will have a random number between 0 and x added to
#   its base stat. So, if the base stat set in the database is 120, and x is
#   set to 30, then that stat will be between 120 and 150 for any instance of
#   that enemy. So, if you are fighting two slimes, then one of them could have
#   that stat be 127 while the other has it at 142, for example.
#
#   If the codes have a percentage to them, then it will take a random number
#  between 0 and x and add that percentage of the stat to the enemy's stat. So,
#  if an enemy's max HP is 200 and you set \variance_hp%[10], then the script
#  will choose a random number between 0 and 10. In this case, let's say it
#  chooses 6, then .06*200 will be added to the enemy's HP, resulting in that
#  enemy having 212 HP

I've always loved your scripts, modern algebra, and this is no exception. This replaces a similar script I used for RMXP functionality back in the day... kudos, good sir.

umm you have an error on line 46...
/SP <=should be /MP right?
and also maxsp_plus should be maxmp_plus

right? I was just trying it out and it crashed on a battle test where I was adding mp to monsters

Ah, yes you are correct

Thanks for pointing it out

Can you add an option that allows you to use percentages in addition to the current script for variance?

Sure. Give me a second.

EDIT::

After class - I got distracted. I will write the extension for you in an hour or two.

Thanks =D

oh, and it's done. I forgot to announce that 

Awesome script.

Umm you used the SP instead of MP again

Spoiler for:

I just changed all the sp to mp XD

You're right. I'm too stuck in RMXP

Can we get this to work with gold and experience from the enemy?

It would be very easy, but for exp it might not be prudent, as it possibly results in harder enemies giving less exp and easy enemies giving more. It might make more sense to develop an algorithm based on the pluses given.
