Minecraft Portal Calculator
I love minecraft--it's way too much fun, and way too time consuming.
Here's a quick calculator that you can use to plug in coordinates from either the overworld or the nether to find out where
your gate is likely to appear given the other constraints the game's algorithm uses to determine where and how gates get hooked up.
Or, said another way, where to build your portal in order to have it's other end materialize where you need it to.
Here are the specific scenarios which I am hoping to have this calculator easily solve.
Wrong Return Gate
I built a portal from my home at X,Y,Z only to land in someone else's portal room in the nether.
This was fine, but when I walked back through it, my X and Z were nowhere near the gate I entered from--instead I came back to that someone elses homestead
and then had to wander across the landscape, at night, a long, long way...it was a frightening journey.
What I needed to do, was get my X,Y,Z coordinates before stepping through the original portal, and then carry in at least ten obsidian and some flint and steel.
From the nether side, I needed to get to X/8, Y, Z/8 and then build a portal back to my original location. I know I know, this isn't new knowledge...I just
hadn't seen the math clearly articulated at any of the pages produced by searches. What to do...?
Calculator to translate between the overworld and the nether
As a web developer with front end experience I figured, why not build a quick calculator to do the translation based on which side I was plugging the coords in from.
- Collect 20 obsidian blocks and create a flint and steel using the recipe.
- Go to the place you want your return portal to appear.
- Hit F3 while in the game and collect your X, Y, and Z coordinates.
- Plug them into this calculator (if you can have a browser open in the background it's quick to alt-tab between the browser and the game without needing to disconnect).
Note: you can either plug the coordinates in one at a time -or- as a comma separated list (for example 100,66,300).
If you only provide two coordinates (such as 100,300) they'll be used to populate X and Z.
- Use the first 10 obsidian to build a nether portal and step into the nether.
- Explore to the coordinates from the calculator (!!USE CAUTION!! --lava, fire, mobs, and falls are some of the major dangers that exist in the nether. Travel and mine with extreme caution. In fact, mine with the shift key down ;-))
- Build your return portal at the coordinates, step through and with any luck you'll be back at the portal you built initially.
Note: If you don't return to the expected portal, investigate more about the conditions the game uses for connecting portals which can be found at the nether portal link above.
I hope this helps you. If you find any errors or have suggestions, please let me know.
