Random Encounters By Level

Encounter Levels
Version: 1.5
Author: modern algebra
Date: July 12, 2008

Description

This script allows the game maker to give monsters levels, and then based on those levels, it determines what enemy troops can be attacked by the player at his current level. That is kind of confusing, so I will try to explain a little better by example. The maker can 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 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 are and an average among each troop is calculated, and with this script you will only be able to fight monster troops that are within level range of your heroes. You can set the level range as well, thus making some maps harder and others easier

Features

• Allows you to set the levels for each enemy in the database
• Only allows the player to fight monster troops within his level range
• Allows you to set what the level range is at any time with a simple call script
• Can be disabled and re-enabled at will
• Easy database configuration

# Encounter Levels Script
# Version: 1.5
# Author: Modern Algebra  (rmrk.net)
# Date: February 5, 2008
#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#  Instructions:
#
#  To give enemies levels, all that you need to do is go to the Notes box of
#  the Enemy in the database and add this code:
#
#    \elvl[<level>]
#
#  If you do not, then the level defaults to be the same as the enemy's ID.
#
#  Then, set up the regular map encounter lists (areas included) with all the
#  monsters that you ever want to appear in that area or map.
#
#  The system basically works by giving monsters levels and by setting a
#  level range within which all encounters must reside. Then, for each troop,
#  an average is calculated from all the enemies in the troop. Thus, that
#  number acts as the troop level, and the script works by making it so that
#  number must be in a certain range of the party's average level for that
#  troop to be encountered. By default, this level range is between (Actor's
#  Average Level - 5) and (Actor's Average Level + 5). The range can be changed
#  at any time to make certain maps harder or easier by using the following
#  code in a call script:
#
#     $game_system.min_level = x
#     $game_system.max_level = y
#
#  Where x, y are the values you are changing them to.
#  Keep in mind that min level, like max level, is added to the party's average
#  level. So, if you set $game_system.min_level = 5, then the minimum level of
#  encounters would be party's average level + 5, not party's average level - 5.
#
#  You can also turn the levelling feature on and off completely at will, using
#  this code:
#
#  $game_system.level_boolean = true (to turn it on)
#  $game_system.level_boolean = false (to turn it off)
#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#  Compatibility:
#   It ought to be compatible with any script that does not modify the
#   make_encounter_troop_id method of Game_Player (and I can't think of any
#   script that would want to besides one like this).

Support

I will fix any bugs that arise and make it compatible with other scripts if any compatibility issues arise. Post in this topic at rmrk for the swiftest response.

Known Compatibility Issues

It ought to be compatible with any script that does not modify the make_encounter_troop_id method of Game_Player (and I can't think of any script that would want to besides one like this).

Author's Notes

Based off the original script I wrote for XP. If you are wondering why it does not retain the Encounter Areas portion of my XP script, that is because areas are a built-in function to VX

Great script! Sounds very useful.

[modern algebra]

UPDATE::

Easier in-database configuration and enemy-specific levels

Now, just set this code in the Notes Field of an Enemy in the database:

\ELVL[level]

[Leventhan]

This script is important for a long game.
Nice one!

[nitrogen4life]

ur script is awesome but i have trouble copying the script.u see,when i copy and paste they appear in one line.every leeters in one line.can u help me pls?its urgent  Thanks

DUDE, you just posted on a topic 2 years old!

[modern algebra]

It doesn't matter that the topic is old, since it is a resource topic. It's far better to have it asked and answered here than in some new topic. Necroing is only bad when it makes sense for it to be bad.

Anyway, the problem is your browser. You are using IE. For some reason, code boxes do not copy correctly when using IE and you will need to use some other browser like Chrome or Firefox. In case you don't have access to another, I have attached a copy of the script as a .txt document.

[Mushu]

What's the scope of this, can u set it like \ELVL[1-99]  for if you always want to fight a mob (in note) or do u put the call script on a parallel process with min and max mob lvl as an event with it?

[modern algebra]

No, you'd have to either turn the feature off by changing $game_system.level_boolean to false or else change the level range by altering the values of $game_system.min_level and $game_system.max_level.

There is currently no way to make some enemies encounterable regardless of level.

[Mushu]

Sorry I figured it out, what I was trying to do earlier was set a mob so it would always show up because when I started using the script I set the lvls and it wasn't working but it is now. I don't know what i messed up it's good now xD
