KTrespass VX

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 a custom note in the item's notebox:

Code:
<passable terrain: 0-63>

NOTES:
  • The VX tileset is composed of very minuscule pieces so you are in need of setting a tile ID range to make the script work properly.
  • You will eventually need to create events that include a special script call in order to retrieve a tile ID.

The Script

Code:
# * KTrespass VX * #
#   Scripter : Kyonides
#   v1.0.1 - 2026-06-27

# Let the player slip into a pond or climb a mountain (no UI included)
# if the party owns a specific item.
# Just leave a note in the item's notebox. Replace TileID with a number.
# You must set ranges because the tileset is composed of very tiny pieces.
#   <passable terrain: TileID1-TileID2>

# * Helpful Script Call * #
# - Get the Next Tile IDs (From Bottom to Top) During Playtest:
# x, y, dir = $game_player.x_y_dir
# $game_map.next_tile_id?(x, y, dir)
