Locator Triangulation

# Locator Triangulation 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.  - 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 ` - attempt to compute the coordinates of player ``, or - `/locator_locate_all` - attempt to compute coordinates of all known targets. ``` /locator_pos1 /locator_pos2 /locator_locate RandomPlayer ```   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 ` - compute coordinates of player `` (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` — compute the intersection coordinates of the view directions (if both positions are saved) ### Keybinds For convenience, keybinds have been added for locator and triangulation. The purpose is to simplify the process of setting points and calculating results. **How it works:** - The first press of the selected key will set the first point. - Pressing the key with **Shift** will skip setting the second point. - Pressing the key again will reset the first point. - Pressing it again will set the second point. - If both points are already set, pressing the key with **Ctrl** will return the calculated result for those two points. ### 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 20° to 150°. Near-perfect accuracy occurs at about 70-100°. If the angle is too small (less than 20°) or too large (150° 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.
