End Portal Calculator Datapack
Find the exact Stronghold End Portal location using only two Eye of Ender throws — powered by real trigonometry! And you thought you'd never need this outside of school… 😁
This datapack calculates the precise coordinates of the End Portal by analyzing the trajectory of two Eye of Ender throws, using angle-based triangulation. No guessing, no wasted time, no digging random tunnels — 100% accurate results.
📋 How to Use
1️⃣ Throw an Eye of Ender and look directly at its center while it's flying and doesn't move mouse

2️⃣ Run the command:
/trigger epc.throw

3️⃣ Move at least 200 blocks away from your first throw location.
4️⃣ Repeat steps 1–2 one more time.
5️⃣ Your End Portal coordinates will appear in chat 🎉
