Description

This script allows you to make it so that only weapons, skills, or items with a certain element can target an enemy, as denoted by you. So, if you want to make a flying enemy that can only be hit by ranged weapons, then you can set it so that only weapons with the element 'Ranged' can hit that enemy.

Features

Allows you to restrict what weapons, etc... can be used to target an enemy
Easy customizability by setting element vulnerabilites in the Notes section of the Enemy

Instructions

See inside the header of the script.

#  Element Immunities
#  Version: 1.0
#  Author: modern algebra (rmrk.net)
#  Date: October 9, 2008
#++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
#  Instructions:
#    Place this script above Main and below Materials in the Script Editor.
#
#    To restrict what elements can harm the enemy, place into the notes section
#   of the Enemy this code:
#
#     \ELEM_VULN[element_ID]
#    
#    You can put as many of them as you like, and that will mean that only 
#   those elements can harm the enemy. If you do not put any, then it will 
#   assume that the monster is vulnerable to all elements. 
#
#    EXAMPLE:
#     If this were in the Notes Box of a given enemy:
#
#      \ELEM_VULN[4]
#      \ELEM_VULN[5]
# 
#    Then any item, weapon, or skill without either element 4 or 5 will not be
#   able to hurt this enemy.

Wow thanks for making this for me.

This is pretty useful for people who haven't rewritten the stupid ONLY MOST EFFECTIVE ELEMENT WORKS part of Game_Battler. Good work!

I'm glad you guys like it, though I'm not entirely sure what you're talking about Craze :P

And no problem Razielboy - it was fun enough to make.

Would this work with Vlad's Requiem ABS?

No.

Problem:
When I attempt to just attack an enemy the game crashes because normal attacks don't have any element. is there a fix for this, or do I need to rewrite the standard attacks system somehow?

Taking it Elsewhere!

Normal attacks do have elements though, because weapons have elements :/

There might be an error if there is nothing equipped though, which might be what you meant?

Try changing this line:

Code: [Select]


      enabled = @enemies[i].element_vulnerable? (tools)

to:

Code: [Select]


      enabled = @enemies[i].element_vulnerable? (tools.compact)

Yes, that's what I meant.
