Alright, I have two spawns in the Normal World:
one at: (which I will call Main
)
x: -22
y: 65
z: 261
and another at: (which I will call Tower
)
x: 17
y: 244
z: 296
Yes, I know that I should have a distance between the two portals of 1024 on either the x
or y
axis, but shouldn't the scan in the Nether pick up the closest portal within a 128 block range?
Get this…
Main
translates to:
x: -2.75
y: 8.125
z: 32.625
and Tower
translates to:
x: 2.125
y: 30.5
z: 37
… in the Nether. Now, in the Nether, I have constructed two portals:
One at: (which I will call nMain
)
x: -2
y: 60
z: 31
and the second at: (which I will call nTower
)
x: 2
y: 67
z: 36
Now, Main
links to nMain
and Tower
links to nTower
, yet both nMain
and nTower
link to Main
. I can't get nTower
to link back to Tower
, which is what I want.
I have:
Tower -> nTower
Main -> nMain
nMain
} Main
nTower
..but I want:
Tower <-> nTower
Main <-> nMain
So, here is my question. Have I configured my Nether portals incorrectly in some way (as in, is Y-Axis now relevant?), or have I simply placed my Normal World portals far too close together (which would suck)?
Thanks everybody!

While converting between Overworld and Nether coordinates, only X and Z are scaled by 8, y remains the same (in your calculation y is also divided by 8). This is not the problem, actually.
Here is how it works: When you enter a portal, the game calculates the ideal point where you should appear on the other side (by scaling X and Z with 8). Then it searches the closest portal to that ideal point.
If you do the calculations backwards (Nether -> Overworld coordinates), you get that entering
nMain
will try to go to here in the Overworld (let's call itnMainOut
):...and 'nTower' will go to here (let's call it
nTowerOut
):The game searches the closest portal to those 'out' points. For both of these 'out' points the closest portal happens to be the
Main
portal at:The distance between points is euclidean distance, that is
If we calculate the distance between
nTowerOut
andMain
we get 55.1If we calculate the distance between
nTowerOut
andTower
we get 177.2That is why
nTower
goes toMain
.With your current setup, I'm afraid it is not possible to build a Nether portal that goes to your
Tower
portal, unless you move theMain
portal down near bedrock and also movenTower
near the top of the Nether.
