My theory is: The game doesn't actually generate more than one portal in hell, no matter how far away you are, so you have to map the hell portals to the real-world ones, not in the other direction as most players would prefer.
I've made more than one portal in hell, by simply going farther underground, or higher, or different places. I've custom placed my portal with this method.

Are you saying that you created new portals in hell yourself, or that the game created new portals in hell because you created new ones in the real world?
I asked because i talked about the second one. I have yet not been able to create a new portal in hell by building a new one in the real world, even after i wandered into the wilderness for a while.
Both. But I was referring to new portals in hell via placing portals in the Overworld. I placed a ton of portals in Overworld to try to get a ghast to spawn, which enabled me to test what this thread was referring to.
THe issue is probably because minecraft doesn't record which portal goes where, but pair them by location, so when the exit portal is moved to place it in a safe place, the system "forget" that the portal already has a corresponding exit.
Only problem is the safe place movement because I don't think safe place if floating midair above a lava sea with the nearest land mass "floating island" approximately 50 blocks away. But the whole forgetting thing sounds like a great theory.
Maybe the portals from the overworld are just making random exits when the portals are spawned in hell. If it isn't the same when coming from player-made portals in hell to overworld then DrLambda's following theory would be correct.
Quote from DrLambda »
Interesting fact: The game is moving portals even if there is a "legal" exit portal position. In my game, when i used my first portal, i was teleported to a floating island in the middle of nowhere close to a lava lake. After i actually tried to find out if the lava lake was the problem and filled it up, i found out that the correct portal exit would be a few blocks away from the lava lake in safe terrain.
After i build a portal there, i was able to teleport back to my original portal, but when entering the original portal, i would still teleport to the floating island.
Let me explain it:
Portals in the home world:
A - In my castle.
B - A few hundred blocks away from my castle, generated when i first teleported back from hell.
Portals in hell:
C - On a floating island. Generated when i first teleported to hell.
D - Near a lava lake, but not actually in the lava lake.
Connected as follows:
A -> C
B -> C
C -> B
D -> A
There was actually no portal that returned to D (in hell).
I added another portal to the home world very close to my spawn, which is like 500 blocks away from my castle and teleporter A, and it STILL teleported me to Portal C in hell instead of creating a second one. This was when i started to suspect something.
I completely leveled the floating island and Portal C, and from there on, Portal A was flawlessly two-way-connected to Portal D.
My theory is: The game doesn't actually generate more than one portal in hell, no matter how far away you are, so you have to map the hell portals to the real-world ones, not in the other direction as most players would prefer.
You make your first portal up on the normal world. Let's call that portal Surface A. Portal A has now created its counterpart in the Nether. We'll call that Nether A. Surface A and Nether A are now linked. At least... that's the theory.
What seems to be happening is that Surface A is trying to create Nether A, but Nether A can't be placed in the Nether due to some issue, whether that be it would be in midair, in lava, or surrounded by blocks. So, the game moves Nether A somewhere it can be placed properly, but now it is not Nether A. It is now Nether B. Since every portal must have a counterpart, Nether B creates another portal up in the normal world, called Surface B.
What about Surface A, then? It no longer has a Nether A to connect with! So, Surface A still thinks Nether B is Nether A, so it sends us there.
However, this theory may not be completely accurate, as I made a third portal on the surface; Surface C and it still sends me to Nether B, the only Nether portal there is. So now all Surface portals lead to one Nether Portal, but the Nether portal only leads up to one Surface portal.
Hope that makes sense.

That seems about right.
Regardless they need to be "fixed". I use that word lightly, though, as it makes it sound as though they are utterly broken. They are just rather useless, to me at least, if they are going to spit me out in an almost completely random spot. I could tolerate a deviation of a couple dozen meters but I've had nether portals generate new portals in the overworld hundreds of meters away from where I entered. If I didn't have cartographer I'd be boned.
the upshot of this glitch is that this could be used to mine obsidian. create portal, enter nether, exit nether, come out game generated portal, reclaim obsidian, go back to original portal, wash rinse repeat. i know lava molding is easier to use but still... free obsidian!

I have been able to create two portals in hell. However the portal to Each one is around..... 1,000+ blocks away form each other.
Better this way, you get a net loss of 2 obsidian if you avoid corners in real world, trim off corners of the portal in hell, then trim the corners off the portal generated in the same chunk
Easy (maybe not from a programming standpoint) solution:
1) Make it check if there is fluid that will flow in. If so, it moves up and down until there is no fluid. If this is impossible to avoid (no fluid is to prevent lava and water from killing you), then and only then does it move (so unless you make a waterfall that falls from the sky all the way to the bedrock, this should never happen)
2) Make it then check to see if it has room. If it does not, it carves out a space around it - say 4x4x4 (the bottom of the frame can be flush with the ground)
3) It then checks below. If there is any air under this 4x4x4 space, it will fill it with cobblestone (only one layer). This keeps you from falling into lava
There. You may still be over a sea of lava, but you are in a safe (ish) spot at least
Might have been said, but why doesn't notch make it so the nether map is offset by the amount of blocks instead of the portal being offset?
That would (theoretically) work for the first portal, perhaps, but what about all subsequent portals? Can't go shifting around the map every time you make a portal... that would just be impossible.

That makes sense, but then the Nether isn't actually generated until you first go there, right? So then why not have it automatically generate a safe place for your portal and then link that portal with your original?
When you create a portal, the game could assign an identifier to it.. Ex, the first portal you create could be '0AA00'. Now when you walk through that portal, it assigns the same identifier to that portal, '1AA00' (The 0 or 1 at the start identifies whether it is a portal in the Core, or the surface world). Now when you walk through portal '1AA00', the game first checks to see whether a portal '0AA00' is still intact... If not, the game creates a new '0AA00'. Otherwise, it sends you to the previous '0AA00'
This will allow Notch to implement his safe-portal algorithm, while maintaining portal consistency.
Yah, this has been happening to me fairly often. My other theory is that each section of the real world has a corresponding location in the neither, because right now i have two portals that really aren't too far from each other going to the same place in the neither.
I have something that'll throw this whole conversation for a loop.
It doesn't happen anymore because I've moved portals so many times in an attempt to fix the problem, but my original portal would teleport me either to the new portal (made in the overworld) or the original portal depending on which direction I was facing when I exited the Nether.
Try and make sense out of that.

Tell me what the greatest game of all time is.
If you get it right you're immediately my best friend.
I think simplest solution to this problem is to have game not move portals in Nether, but instead create a space for portal to be spawned at correct location.
For instance, say when you enter portal in world, on Nether side there is a lava lake at that location, game could simply generate like a 6x6 square of blocks 1 above whatever obstacle is in way, in this case lava, then create portal on top of that. Drawback is you may end up on a small platform in middle of a lake or in air for instance. However this would fix the problems of multiple portals being created all over place, and wouldn't require too much work to do..
If notch wished to get more elaborate and didn't' like idea of portals spawning on isolated islands in middle of a lava lake for instance, then put some kind of check that draws a thin platform from portal to closest land that would connect that island, this way at least player wouldn't' be stuck on an island but instead may have to run along a very thin (1 block wide?) bridge to nearest piece of solid land :smile.gif:

Just a little note, capital letters are used at the start of sentences, not every word. How you've written that is like a literary jackhammer :S

This still might be true to some extent.

Jesus that was the worst sentence I've ever typed out.

Ok people I understand that you don't like every word typed with a capital.
