Encounter Rates
by Mithran

Introduction
By default, all troops are encountered at a completely even ratio depending on the list given for the map. There is no way to make a certain troop be rare, and another really common without flooding the map or area encounter list with a single type of troop. This simple script changes that problem.

Features
- Changes the chance for you to encounter a certain troop

Screenshots
N/a

CODE

  
# Custom Encounter Chance by Mithran
# This simple little script searches for a string tag in the name of the troop
# <n> where n is the encounter rate of the troop.  The default encounter rate is
# 10.  This script takes all the values of every troop in a map list and adds
# that amount of troops to the encounter list, then picks one at random.
# The script removes the string tag at title, in case you want to use the troop
# name for other purposes.
#
# EXAMPLE:
# If you had three troops on your map encounter list,
# Slime <20>
# Slime*2
# Gold Slime <1>
# You would have a 20/31 chance to encounter Slime, a 10/31 chance to encounter
# Slime*2 and a 1/31 chance to encounter Gold Slime.
#
# Place above all other custom scripts and below default scripts
#
# Encounter rates can be changed through the script command in events by using
# $data_troops[n].custom_encounter_chance = x
# Where n is the troop number and x is the encounter rate.
# The change is permanent until the game is exited (it does not save in savefile)
#
# An easier way to set different rates for different maps would be to copy the
# troops and change the name.


class Game_Player < Game_Character
  def make_encounter_troop_id
    encounter_list = $game_map.encounter_list.clone
    for area in $data_areas.values
      encounter_list += area.encounter_list if in_area?(area)
    end
    if encounter_list.empty?
      make_encounter_count
      return 0
    end
    real_encounter_list = []
    encounter_list.each { |value|
      chance = $data_troops[value].custom_encounter_chance
#      print chance.to_s + " " + $data_troops[value].name #~ Debugging
      for i in 1..chance
        real_encounter_list.push(value)
      end
    }
    return real_encounter_list[rand(real_encounter_list.size)]
  end
end

class RPG::Troop
  attr_accessor :custom_encounter_chance
  def custom_encounter_chance
    make_encounter_cache if @custom_encounter_chance == nil
    return @custom_encounter_chance
  end
  def make_encounter_cache
    @custom_encounter_chance = 10
    @name.gsub!(/<(\d+)>/, "")
    @custom_encounter_chance = $1.to_i unless $1 == nil
  end
end

class Scene_Title < Scene_Base
  alias load_database_mithran_encounterchance load_database
  def load_database
    load_database_mithran_encounterchance
    setup_encounter_chances
  end
  def setup_encounter_chances
    for troop in $data_troops.compact
      troop.make_encounter_cache
    end
  end

Author's Notes
A simple script, use or modify as you see fit. Let me know if you have any questions.

oh this is cool nice little add on, thanx.

I do't like giving bad news, but ...
I think there is a easier way to change the rarity of the enemies ...
If you want an enemy more common than another, just add the enemy more times in the same area.

Example:
If you add 5 Slime and 1 Bat, then there will be a 1/5 of chance that appear a Bat in that area.

But... I haven't verified this... I guess that can be done that way, because it's easier...

You are correct sir , although the chance to encounter a bat would be 1/6.

This is exactly what this short little script is intended to do. It simply adds the denoted amount of each troop to every encounter list they appear in. I found it much less time consuming to set a couple database note tags than repeatedly add several of each enemy to stack the odds against finding a certain one. FYI, this script will 'stack' with adding several of the troop to the encounter list, IE, each iteration of the troop in the map encounter list will add the number set in the database tag to the actual encounter list. Feel free to use either, or both, however you want, just thought someone might find it useful (it was *really* annoying making a 'rare' monster in the traditional way).

[ANI-VVB]

You're right about that
To do it the easiest way would create a big problem with the data.
And... yes ... it was annoying...

(I think that only serves to confuse more the poor noobies... )

Sorry!

Another great script, Mithran, thank you! Tried and works perfectly! This'll work well with the Blue Mage script to make the monsters that use the best techniques be harder to find.
