/*:
 * @plugindesc (v1.0) - Different images for enemies in battle
 * @author Pheonix KageDesu
 * @target MZ MV
 * @url https://kdworkshop.net/alter-battlers/
 * @help
 * [Description]
 * 
 * This plugin allows you to add a level of randomization to the
 * appearance of enemies in battle. Specifically, it allows you to
 * assign multiple images to one enemy, and then have the game
 * randomly select one of those images to be used when that enemy
 * is encountered in battle.
 * This can add an element of surprise and variety to encounters.
 * 
 * Packages with alternative enemies images
 * you can find here: https://kdworkshop.net/category/resources/
 * -------------------------
 * [Usage]
 * 
 * Image name rules:
 * [ORIGINAL]_alt(X).png
 * 
 * Exapmle:
 * Original image name: Goblin.png
 * Alternatives: Goblin_alt1.png, Goblin_alt2.png, Goblin_alt3.png
 * 
 * (Numbers should starts from 1)
 * 
 * Add Note <alternatives:X> to Enemy Note that uses Goblin.png image
 * Example: <alternatives:3>
 * 
 * Or you can use Goblin_altX.png image if you don't want that
 * default image (Goblin.png) appears in battle
 *
