Overview

PayTp is a lightweight Fabric mod for Minecraft that allows players to teleport by paying a certain amount of in-game currency (items).
It supports flexible teleportation modes, multi-language localization, and fully customizable cost rules.

---

Features

• Editable command names
• Cross-dimension teleport to a specified location
• Player teleport request system
• Home and Back
• Beacon waypoint (Warp) feature
• Fully customizable JEXL teleportation price and distance algorithm
• Ender Chest / Shulker Box payment support
• Cloth Config API support (client-side)
• Can be used as a server-side only mod

Most features can be disabled by setting their corresponding command names to an empty string. For example, changing teleport.coordinateCommand in the config file from ptp to empty will disable the coordinate teleport function. The in-game help guide will automatically adapt.

---

Commands

All displays show the default command names, where <> indicates required parameters and () indicates optional parameters

Every <player> argument accepts and suggests online player names only; entity selectors such as @a, @p, and @s are not supported. The /ptp <x> <y> <z> text is a non-selectable format hint rather than a current-coordinate suggestion; ~ and ^ relative coordinates remain supported.

safeTeleport	boolean	Move an unsafe destination to the nearest safe position; defaults to false.
safeTeleportRange	int	Maximum horizontal and vertical safe-position search range; defaults to 5 and must be from 1 to 64.

Teleport Effects (general.effect)

Field	Type	Description
particleEffect	boolean	Enable teleport particles; defaults to true.
soundEffect	boolean	Enable teleport sounds; defaults to true.

---

Coordinate Teleport

Field	Type	Description
coordinateCommand	string	Coordinate teleport command (default /ptp).
allowCrossDim	boolean	Whether any teleport method may cross dimensions; defaults to true. When disabled, the dimension argument is not registered or displayed.

---

Teleport Request System

Request Commands

Field	Type	Description
toCommand	string	Command to request teleporting to the target player (default /ptpto).
hereCommand	string	Command to request the target player to teleport to your location (default /ptphere).
acceptCommand	string	Command to accept a request (default /ptpaccept).
denyCommand	string	Command to deny a request (default /ptpdeny).
cancelCommand	string	Command to cancel a sent request (default /ptpcancel).

Configuration

Field	Type	Description
expireTime	int	Request expiration time in seconds; defaults to 10 and must be non-negative.

---

Home System

Field	Type	Description
homeCommand	string	Command to teleport home (default /ptphome).
setRespawnPoint	boolean	Also move the player's respawn point when setting home; defaults to false. When the player respawns at Home, the vanilla bed stand-up position resolver is always used; if it finds no valid position, the player is moved to the world spawn point.

---

Back System

Field	Type	Description
backCommand	string	Command to return to previous location (default /ptpback).
maxBackStack	int	Maximum saved historical positions; defaults to 10 and must be greater than zero.

prioritizeShulkerBox	boolean	Prioritize Shulker Box deduction; defaults to false and requires allowShulkerBox.

---

JEXL Price Algorithm

The price.algorithm string contains both the distance calculation and the price calculation. There are no fixed Java-side distance formulas or teleport multipliers. A script may be as simple as 10, which returns a fixed price of 10.

Available Variables

Variable	Type	Available methods
from	position	.x(), .y(), .z(), .dimension()
to	position	.x(), .y(), .z(), .dimension()
context	context	.coordinate(), .home(), .back(), .request(), .warp()
player	player	.uuid(), .name()
callback	callback	.onSuccess(), .onFailure()

context contains five nullable nested records. Exactly one accessor returns a record for each execution; the other four return null:

Accessor	Record contents
context.coordinate()	Coordinate-command context; currently empty.
context.home()	Home context; currently empty.
context.back()	Back context; currently empty.
context.request()	otherPlayer() returns the other player with uuid() and name(); isRequester() is a bool indicating whether the current player initiated the request.
context.warp()	name(), accessType(), and owner(); the owner has uuid() and name().

isRequester() is true when the current player initiated the request and false when they accepted a request to teleport to its sender. Warp accessType() is owned, invited, server, or public; owner() is null for an ownerless server waypoint.

Teleport Callbacks

callback.onSuccess() and callback.onFailure() are independent callback chains for each teleport. Use += to append any number of JEXL lambdas. Save a lambda to a variable first if it may later be removed with -=:

var audit = () -> {
  minecraft:execute("scoreboard players add " + player.name() + " tp_success 1");
};

callback.onSuccess() += audit;
callback.onSuccess() += () -> {
  minecraft:execute("tell " + player.name() + " Teleport completed");
};
callback.onSuccess() -= audit;

callback.onFailure() += () -> {
  minecraft:execute("scoreboard players add " + player.name() + " tp_failed 1");
};

Callbacks execute in registration order. Removing one requires the same lambda object; repeating the same lambda expression creates a different object. A callback error is logged without stopping later callbacks. The price script runs before destination validation so that an unavailable world, missing safe destination, or disabled cross-dimension teleport can invoke callback.onFailure(); to therefore represents the originally requested destination. No payment is taken until all destination checks pass. A maxPrice of 0 bypasses the price script, so no callbacks are registered.

crossDimension is intentionally not provided. Determine it inside the script:

var crossDimension = from.dimension() != to.dimension();

Return Value and Strict Mode

• The last expression must return an int. Integer literals such as 10 already satisfy this requirement.
• Returning a negative integer cancels the payment and teleport. This allows an algorithm or Minecraft command result to deliberately stop the operation without causing a script error.
• JEXL runs in strict mode, so undefined variables and invalid expressions are treated as errors.

Math Methods

🔔 Use math for distance, multiplier, rounding, and boundary calculations directly inside the price algorithm without invoking an external process.

The math namespace exposes Java's built-in Math methods.

Method	Return type	Description
math:sqrt(value)	double	Returns the square root of a value.
math:max(first, second)	numeric	Returns the greater of two values.
math:min(first, second)	numeric	Returns the smaller of two values.
math:round(value)	long	Returns the closest integer value.
math:pow(base, exponent)	double	Raises base to the supplied power.
math:abs(value)	numeric	Returns the absolute value.

Methods may return a numeric type other than int. Convert the final result explicitly when necessary:

math:round(rawPrice).intValue();

Minecraft Commands

⚠️ The minecraft namespace can execute every command registered with the server, including commands added by other mods. Commands run as the server console with ALL_PERMISSIONS, so they can perform destructive or administrative operations such as op, ban, data, and stop. Only use algorithms from fully trusted sources.

Method	Return type	Description
minecraft:execute(command)	int	Executes a Minecraft command. The leading / is optional and command feedback is suppressed.

The server—not the teleported player—is the command source, so @s cannot be used to refer to the player. Use the algorithm's player.name() when a command needs a player target. Commands involving locations or dimensions should specify their target, coordinates, and dimension explicitly instead of relying on player-relative command context:

minecraft:execute("scoreboard players add " + player.name() + " teleport_count 1");
minecraft:execute("effect give " + player.name() + " minecraft:regeneration 5 0");
10;

During configuration validation, minecraft:execute(...) returns 0 without running the command, so loading or editing an algorithm cannot modify server state.

Shell Commands

‼️ The shell namespace executes arbitrary commands with the same operating-system permissions as the Minecraft server. Only use algorithms from fully trusted sources. Shell commands are synchronous and therefore block the server thread until they finish. They are also executed during algorithm validation, including config loading, editing, and importing.

Method	Return type	Description
shell:execute(command)	ShellResult	Executes through /bin/sh -c on Unix-like systems or cmd.exe /c on Windows.
shell:run(command)	string	Returns standard output, or throws an error when the exit code is non-zero.
shell:runInt(command)	int	Requires standard output to contain exactly one valid integer.

ShellResult exposes exitCode, stdout, and stderr:

var result = shell:execute("python3 /opt/paytp/price.py");
result.exitCode == 0 ? result.stdoutInt() : 0;

For a price algorithm, runInt is usually the simplest form:

shell:runInt("python3 /opt/paytp/price.py '" + player.name() + "'");

Example Algorithm

// Available variables:
//
// Variable | Available methods
// -------- | -----------------------------------------------------------
// from     | .x(), .y(), .z(), .dimension()
// to       | .x(), .y(), .z(), .dimension()
// context  | .coordinate(), .home(), .back(), .request(), .warp()
// player   | .uuid(), .name()
// callback | .onSuccess(), .onFailure()
//
// Java's built-in Math methods are available through the "math" namespace.
// Minecraft commands are available through minecraft:execute("command").
// Full system shell access is available through the "shell" namespace.

var basePrice = 1;
var baseRadius = 10.0;
var pricePerBlock = 0.01;
var crossDimensionMultiplier = 1.5;
var homeMultiplier = 0.5;
var backMultiplier = 0.8;
var warpMultiplier = 0.5;

var deltaX = from.x() - to.x();
var deltaY = from.y() - to.y();
var deltaZ = from.z() - to.z();
var distance = math:sqrt(deltaX * deltaX + deltaY * deltaY + deltaZ * deltaZ);
var multiplier = from.dimension() != to.dimension() ? crossDimensionMultiplier : 1.0;

if (context.home() != null) {
  multiplier = multiplier * homeMultiplier;
} else if (context.back() != null) {
  multiplier = multiplier * backMultiplier;
} else if (context.warp() != null) {
  multiplier = multiplier * warpMultiplier;
}

callback.onSuccess() += () -> {
  minecraft:execute("effect give " + player.name() + " minecraft:weakness 1 1");
};

var distanceBeyondBase = math:max(0, distance - baseRadius);
math:round((basePrice + distanceBeyondBase * pricePerBlock) * multiplier).intValue();

The default algorithm additionally handles Nether coordinate scaling and The End. It is written into a newly generated configuration file and can be used as a complete starting template.

Validation and Final Price

1. If maxPrice is 0, the algorithm is not executed and every teleport costs 0.
2. A negative script result cancels the payment and teleport without being clamped.
3. Otherwise, the script result is forcibly clamped to the inclusive range [minPrice, maxPrice].
4. The script is compiled and test-executed when the configuration is validated. In Mod Menu, invalid input is marked red and prevents saving.
5. If an algorithm fails during an actual teleport, calculatePrice returns -1; PayTp logs the error, cancels the teleport, and notifies the player that the payment process failed.

---

Cloth Config Support

If the Cloth Config API is installed, all settings can be adjusted directly through the in-game Mod Menu GUI. The price algorithm can be edited in a dedicated multi-line editor or imported from a .jexl file. Confirming an edit or importing a file immediately validates its compilation and integer output; invalid algorithms cannot be saved. (World restart may be required.)
