KTrespass XP

by Kyonides

Introduction

Let the player do crazy stuff like slipping into a pond or climbing a mountain (no batteries nor UI included) by just owning a very specific item.

Everything is handled by the very short KTrespass module. Just add an item ID to the Hash and set its corresponding Array of Terrain Tags, and that's it! :D

NOTE: Game_Player#passable? method has been overwritten on purpose to keep the script as simple as possible.

The Script

Code:
# * KTrespass XP * #
#   Scripter : Kyonides
#   v1.0.1 - 2026-06-26

# Let the player slip into a pond or climb a mountain (no UI included)
# if the party owns a specific item.
# Just configure the TERRAIN_ITEMS Constant below accordingly.

module KTrespass
  TERRAIN_ITEMS = {} # Better leave this line alone!
# Terrain Tags: Never include 0 in the array!
# [ItemID] = [Tag1, etc.]
  TERRAIN_ITEMS[26] = [1,2]
end
