Locator Triangulation

build

A client-side Fabric mod that allows determining players' coordinates using triangulation.

The mod calculates coordinates using publicly available data accessible to regular vanilla players and acts solely as a calculator. If the vanilla locator is disabled on the server or a player has hidden from it, the mod will not be able to determine their coordinates. Essentially, all calculations performed by the mod can be done manually with a calculator and the vanilla client.

Quick start

The map is for example purposes only.

map

  • Run /locator_pos1 - the mod will remember the locator's state, your current position and your view yaw.
  • Move away as far as possible so the angle to the target becomes as large as possible, then run /locator_pos2.
  • Run:
    • /locator_locate <name> - attempt to compute the coordinates of player <name>, or
    • /locator_locate_all - attempt to compute coordinates of all known targets.
/locator_pos1
/locator_pos2
/locator_locate RandomPlayer

locate_RandomPlayer command

triangulation lines

The larger the angle between directions from the two points, the more accurate the coordinates.

For regular triangulation use the same commands but with the triangulation prefix.

Command description

Locator commands

  • /locator_data - print current locator state
  • /locator_pos1 - save the first position (locator state and your coordinates)
  • /locator_pos2 - save the second position (locator state and your coordinates)
  • /locator_get_poses - print the saved positions
  • /locator_clear_pos1 - clear the first position
  • /locator_clear_pos2 - clear the second position
  • /locator_clear_poses - clear both positions
  • /locator_locate <name> - compute coordinates of player <name> (if both positions are saved)
  • /locator_locate_all - compute coordinates for all known targets (if both positions are saved)

Regular triangulation commands

  • /triangulation_pos1 - save the first position (your coordinates + yaw)
  • /triangulation_pos2 - save the second position (your coordinates + yaw)
  • /triangulation_get_poses - print the saved positions
  • /triangulation_clear_pos1 - clear the first position
  • /triangulation_clear_pos2 - clear the second position
  • /triangulation_clear_poses - clear both positions
  • /triangulation_locate โ€” compute the intersection coordinates of the view directions (if both positions are saved)

Accuracy notes

Triangulation accuracy strongly depends on the angle between view directions from the two positions. Good results are achieved with an angle between directions from 20ยฐ to 150ยฐ. Near-perfect accuracy occurs at about 70-100ยฐ. If the angle is too small (less than 20ยฐ) or too large (150ยฐ and above), accuracy drops significantly.

For maximum accuracy, take positions so that the target is roughly at a right angle relative to you.

The corner color in the message indicates the calculation quality. Green means near-perfect accuracy, yellow is acceptable but may include a small error, and red indicates poor accuracy.

How to hide from the locator

There are several ways to hide from the radar: sneaking (Shift), a mob's or another player's head, a carved pumpkin, or an invisibility potion.
