A prettier, faster Minecraft stronghold calculator — built on top of Ninjabrain-Bot.
I was bored of the boring themes, so I forked NB and gave it a proper glow-up: modern light & dark mode, performance improvements, and multi-stronghold tracking across rings.
All the brilliant triangulation math is from Ninjabrain1 — see triangulation.pdf for the underlying mathematics.
| Feature | Ninjabrain-Bot | Strongy |
|---|---|---|
| UI framework | Swing | JavaFX with CSS themes |
| Themes | 10 hardcoded themes | Light + Dark mode, custom CSS themes |
| Clipboard reading | 100ms polling loop | Event-driven (FlavorListener) |
| Calculation speed | Standard | Separable convolution, parallel conditioning |
| Multi-stronghold | Shows closest only | Toggle to track across all rings |
| Java version | Java 8 | Java 17+ |
Download the latest release and run the jar.
- Throw an ender eye in Minecraft
- Look at it and press F3+C
- Repeat for as many eyes as you like
- Strongy gives you a certainty percentage and stronghold coordinates
For subpixel accuracy, set hotkeys for "+0.01/-0.01 to last angle" in advanced options and calibrate your standard deviation.
- Most accurate known triangulation algorithm (inherited from Ninjabrain-Bot)
- Accounts for user error and all known stronghold generation mechanics
- Certainty percentage describes prediction confidence
- Modern UI with light/dark mode toggle
- Multi-stronghold tracking — see predictions across all stronghold rings
- Subpixel adjustment for perfect travel
- Blind coord evaluation (press F3+C in the nether)
- Fossil divine — look at fossil start and press F3+I
- OBS overlay with auto-hide
- Built-in HTTP API for external tool integrations
- Event-driven clipboard — no more CPU-wasting polling
Yes. Strongy uses the same calculation engine as Ninjabrain-Bot, which has been legal since the calculator unban on 2021-12-09.
You most likely moved while throwing an eye. It takes longer than you'd think for the player to fully stop — even when F3 coordinates appear stationary, there's client-server desync. Push yourself into a corner between two blocks to stop quickly.
Set hotkeys for "+0.01 to last angle" and "-0.01 to last angle" in advanced settings. See the perfect travel document for details.
It controls how coordinates are presented — does not affect accuracy:
- (4, 4) — starter staircase coordinates
- (8, 8) — chunk center coordinates
- Chunk — chunk coordinates
Describes how accurately you measure ender eye angles. Lower = bot trusts your readings more. Typical ranges:
- 0.050 - 0.200 — quake pro FOV
- 0.020 - 0.040 — 30 FOV
- 0.005 - 0.010 — 30 FOV with subpixel adjustment
Use "Calibrate standard deviation" in settings to find your optimal value.
When enabled, Strongy shows predictions for strongholds across multiple rings simultaneously, not just the closest one. Useful for advanced routing.
