KantoTeleports

KantoTeleports is a Fabric utility mod that lets map creators and server owners build configurable teleport points using dedicated teleport blocks.

The mod was originally created for the CobbleKanto project, where it is used for map transitions, doors, interiors, dungeons, special rooms, and adventure progression. It can also be used in other Fabric worlds or servers that need simple, controlled, block-based teleport systems.

KantoTeleports is focused on builders: place a teleport block, set its destination, optionally choose a sound, optionally require an item, and let players move through your map in a cleaner way.

How It Works

KantoTeleports adds a physical teleport block that can be configured directly inside the world.

A configured teleport block can store:

a target position
a sound event
a required item
an optional Room Session ID

When a player steps on the teleport block, the mod briefly applies a transition effect, then teleports the player to the configured destination.

Show setup and command details

Basic Teleport Setup

Place a Teleport Block in the world.
Hold the Teleport Setter item.
Right-click the teleport block.
Right-click the destination block.

The destination is saved as the space above the block you clicked, centered on that block.

For example, if you right-click the floor where the player should appear, the teleport destination will be set one block above that floor.

Setting a Teleport Sound

Look directly at a teleport block and run:

/kantoteleports set sound <sound_event>

Built-in sound examples:

/kantoteleports set sound kantoteleports:teleport_generic
/kantoteleports set sound kantoteleports:teleport_door

The command accepts registered sound event IDs.

Setting a Required Item

Hold the required item in your main hand, look directly at a teleport block, and run:

/kantoteleports set item

After that, players must have a matching item in their inventory to use that teleport.

This is useful for key items, tickets, badges, dungeon passes, quest rewards, or other progression gates.

Room Sessions

Room Sessions are used when one teleport should send players to the first available room from a configured list.

This is useful for:

private challenge rooms
repeatable dungeon rooms
event rooms
arenas
hotel-style interiors
multiplayer adventure-map instances

Room Session data is saved inside the world folder:

config/kantoteleports/room_sessions.json

Create a Room Session

/kantoteleports roomsession create <session_id>

Example:

/kantoteleports roomsession create gym_rooms

Add a Room to a Session

Use two positions to define the room area:

/kantoteleports roomsession add <session_id> <room_id> <pos1> <pos2>

By default, the teleport target will be the center of the room box.

You can also define a specific target position:

/kantoteleports roomsession add <session_id> <room_id> <pos1> <pos2> <target>

Example:

/kantoteleports roomsession add gym_rooms room_1 100 64 100 110 70 110 105 64 105

Link a Teleport Block to a Room Session

Look directly at a teleport block and run:

/kantoteleports roomsession set <session_id>

When players step on that block, the mod checks the session rooms and sends each player to an available room.

Other Room Session Commands

List rooms in a session:

/kantoteleports roomsession list <session_id>

Remove a room from a session:

/kantoteleports roomsession remove <session_id> <room_id>

Clear the Room Session ID from the teleport block you are looking at:

/kantoteleports roomsession clear

Enable or disable the Room Session system globally:

/kantoteleports roomsession enabled <true|false>

All setup commands require operator/admin permission.

Recommended Uses

KantoTeleports works well for:

door transitions
cave entrances
building interiors
region gates
server hubs
event rooms
dungeon checkpoints
shortcuts
passages
private challenge rooms
multiplayer room allocation systems

Builder Notes

For best results:

Install the mod on both the server and client.
Configure teleports before opening the world to regular players.
Keep backups before editing room_sessions.json manually.
Use clear session IDs and room IDs, such as gym_rooms, dojo_rooms, or event_rooms.
If you replace the built-in audio files, keep the same sound IDs if you want existing configured blocks to keep working.

Known Issues

Room Sessions depend on correctly defined room boxes. If a room area is too small or incorrectly positioned, availability checks may not behave as expected.
If a teleport destination is blocked, the mod tries to move the target upward, but builders should still test every teleport location manually.

Compatibility & Dependencies

Required:

Minecraft 1.21.1
Fabric Loader 0.16.9 or newer
Fabric API
Java 21

Optional:

Jade, for builder tooltip information on configured teleport blocks

FAQ

Does KantoTeleports require Cobblemon?

No. KantoTeleports was created for the CobbleKanto project, but the mod itself does not require Cobblemon.

Does the mod need to be installed on both client and server?

Yes. The mod adds blocks, items, models, sounds, and server-side teleport logic, so it should be installed on both sides in multiplayer.

Can I use this in my own adventure map or server?

Yes. The mod is useful for custom maps, server hubs, dungeons, private rooms, progression gates, and other builder-controlled teleport systems. Feel free to create and publish videos about/with this mod!

Can I lock a teleport behind an item?

Yes. Hold the item in your main hand, look at the teleport block, and run:

/kantoteleports set item

Players will need a matching item in their inventory to use that teleport.

Can I change the teleport sound?

Yes. Look at the teleport block and run:

/kantoteleports set sound <sound_event>

Built-in examples:

/kantoteleports set sound kantoteleports:teleport_generic
/kantoteleports set sound kantoteleports:teleport_door

Will replacing the audio files break existing teleport blocks?

Not if the sound IDs stay the same. Existing blocks store sound IDs such as kantoteleports:teleport_generic or kantoteleports:teleport_door, not the audio waveform itself.

Where are Room Sessions saved?

Room Sessions are saved in the world folder:

config/kantoteleports/room_sessions.json
