Emma's Stronghold Finder

Throw one eye of ender and the stronghold is pinned on your HUD: its Overworld and Nether coordinates, the distance and the direction from where you stand. If one throw can't settle it, it tells you exactly where to step before the next one.

Watch how it works (and the maths behind it): https://youtu.be/18dk8xQVLMY

Three ways to use it

• Exact mode (the mod, default) – just throw. No keypress. It reads only what your client is already sent about the eye's flight, and one throw settles it about 97% of the time (measured over 20,000 simulated throws). When it can't, it tells you how far to step so the next eye does.
• F3+C mode (the mod) – throw, look at the eye, press F3+C, like speedrun calculators. It plans your next throw spots and shows the stronghold with a certainty %. Default: 3 throws.
• Desktop app (no mod) – a small always-on-top window that reads only your F3+C text, for vanilla play. Free download: https://emmaandelric.us/stronghold-finder

Features

• Pin that stays – once found, the stronghold stays on your HUD, saved per world, in every dimension (Nether coordinates included).
• Where to step – the next throw spot with an arrow, distance and F3 facing.
• Aim and Throws settings (F3+C mode) – Aim: Careful, Normal, Relaxed or Loose, how far off the eye your crosshair really is. Throws: 2 to 5, how many throws to plan for (2 is meant for Nether travel).
• Languages – follows your Minecraft language: English, Deutsch, Español, Français, Português and 日本語.
• Symbols display – no words at all, for videos with several audio languages.
• Keys – J cycles the HUD (details, location only, off), Shift+J opens the options. Nothing takes your mouse or keyboard.

Fair play

No seed, no server data, no extra packets: only what the vanilla client already sees. The mod is made for normal play and is not speedrun.com-legal (leaderboard runs only allow listed mods). The desktop app isn't legal for runs either until the Minecraft speedrun moderators add it to their tool list.

Installation

Client only. Install Fabric Loader, Fabric API and this jar for Minecraft 26.3. Works on any server, single player included. F3+C mode needs F3+C to be allowed (servers with reduced debug info turn it off; use Exact mode there).
