[VXA] Random Encounters by Level

Random Encounters by Level
Version: 1.0.0
Author: modern algebra
Date: 22 September 2012

Version History

• <Version 1.0> 2012.09.22 - Original Release

Description

This script allows you to assign levels to enemies and have it so that enemy will only be randomly encountered when the player's level is within some range of that enemy's level. You can set the level range by map.

That might be confusing, so I will try to explain a little better by example. You set up a map with possible enemies being Angels, Cherubims, and Seraphims. You can enter this map at any time, and so you want the random encounters to reflect what level the hero party is. You don't want the party attacking Seraphims when they are level 1, because they will be crushed, and you don't want them to fight Angels when they are level 99, because it's too easy. Thus, you just set up in the script what levels the enemies with this script you will only fight monster troops that are within level range of your heroes. You can set what that level range is as well, thus making some maps harder and others easier.

Features

• Allows you to assign levels to every enemy in the database
• The player is restricted to randomly encountering only enemies within his or her level range
• Allows you to set the level range by map or in an event by script command
• Can be disabled and re-enabled at will
• Simple database configuration

Instructions

Paste the script into its own slot in the Script Editor, above Main but below Materials. For further instructions on configuration, see the header of the script.

#   thus making some maps harder and others easier.
#++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
#  Instructions:
#   
#    Paste this script into its own slot in the Script Editor, above Main but
#   below Materials.
#
#    To set the level of an enemy, all you need to do is place the following
#   code in its notebox:
#
#      \elvl[x]
#       
#   Replace the x with the level you want to assign to the enemy. As an example
#   if you wanted to set an enemy's level to 7, you would use the following
#   code:
#
#      \elvl[7]
#
#   If you do not give an enemy a level, then it will be encounterable at any
#   level. The level of any given troop is the average level of all its members.
#
#    By default, your party will only encounter troops that are within 5 levels
#   of your party. In other words, if the average level of your party is 7, you
#   will encounter troops with levels between 2 and 12. You can change the
#   level range in two ways.
#
#    Firstly, you can change it by map by placing the following code in the
#   notebox of a map:
#
#      \elvl[x, y]
#
#   Replace x and y with the minimum and maximum level difference. So, if you
#   have something like:
#
#      \elvl[-2, 8]
#
#   Then the parties will encounter enemy troops that are between 2 levels
#   below the party and 8 levels above the party. Alternately, if you did this:
#
#      \elvl[v1, v2]
#
#   Then it would set the minimum level to the value of variable 1 and the
#   maximum level to the value of variable 2.
#
#    Secondly, you can change the level range by placing the following code in
#   a Script event command:
#
#      set_encounter_level_range(x, y)
#
#   where, again, you replace x and y with the minimum and maximum level
#   diference.
#
#    You can turn this script off and on completely with the following code:
#
#      $game_map.marel_on = false    # <- OFF
#      $game_map.marel_on = true     # <- ON

I adopt RMRK's default Terms of Use.

I assume this could be doubled up with Yanfly's Enemy Levels somehow? You could make the enemies "evolve" then.

Yes, they very likely would work together, but I'm not sure what you mean by evolve. I assume that Yanfly's Enemy Levels script will make any enemy the same level as the party. To the extent that this Random Encounters by Level script is used, you could make it so that you stop fighting that particular enemy after the party reaches whatever level you specify, even though the enemy would otherwise always be the same level as the party.

Actually this is way easier to balance than Yanfly enemy levels. I'll try this out, thanks MA!
