    NetherPortal v0.6.11

    New in Version 0.6.11:
    • Added NetherPortal.portal.use permission

    I always thought things like random tping around that make the game too easy takes away the fun of playing, but in SSP fast travel constrained by 8x ratio rule was fun and reasonable advantage considering that you had to go through the nether a dangerous place to set up portals there, and if you wanted to make the travel safer you'd have to build or dig to make it safe. Unfortunately I have not seen a single plugin that does the following:

    1. Fast travel (8x rule)
    2. Auto portal creation (i.e. when you go through a portal a portal is created at the destination that is linked to it)
    3. Multiworld

    Well this plugin does. But it is also different from other plugins.

    The challenging thing is of course how to match portals. One thing I did not like in SSP was portal hopping, making it possible to easily find caves by digging down in the nether and place a portal there , and travel ultra fast by placing portals where there was solid material on the nether side. One solution to this was creating airpockets and platforms as in NetherGate. While this preserves the 8x rule, it is a bit dangerous to use, since you can destroy things you've built, and alternatively it would make it difficult to program to avoid it.

    The easy solution for me, which also adds a bit of challenge in setting up working portals, is that portals simply do not work if there is not air for the portal to be created in, the portal exits on both sides, and a platform for the portal and you to stand on when you exit it. So the challenge is to find a suitable location for a portal, but you can do it with the aid of a compass which gives a rough indication of the probability of there being a suitable location nearby, the closer the greater. The compass will also give you a guaranteed indication "X" that there is one solid block underneath and 5 air blocks above and one solid block underneath and at least 1 but at most 4 "_". The shape of the "X" indications in the following form:
    will guarantee that a portal can be constructed here, however if you have linked the world to more than 1 other world, readings from another world could interfere and you lose this guarantee, even though it is not likely to fail. Note, the exact size of the shape depends on the ratio between your world and the target world. If you are going to the nether from a normal world with default ratios (1 to 8) the shape is 8 times bigger. Note also that each indication then represent the entire 8x8x8 cube.
    If you are going to a higher or equal scale world, the portal has to be placed so the two bottom middle blocks reside within the two middle blocks of the shape.
    If you are going to a lower scale world, a special portal indication "N" "S" "W" or "E" is needed to guarantee that a portal can be placed, indicating the direction the other bottom middle block of the portal from the block you stand on (which is one of the bottom middle blocks).

    To get any reading at all YOU HAVE TO LINK THE WORLDS using the WORLD LINK or WORLD TARGET commands for a one way link.

    Here is a top down schematic view of all blocks needed on each level of a suitable location for a portal:
      S  |  A  |  A  |  A  |  A  |  A
     SSS |  A  | AAA | AAA |  A  |  A
     SSS |  A  | AAA | AAA |  A  |  A
      S  |  A  |  A  |  A  |  A  |  A
    y-1    y     y+1   y+2   y+3   y+4
    Where S is solid i.e. non air block and A is air block.

    Blocked portal occurs because you try to punch through destroying an existing portal.

    Edit: You can have them like in the first figure, if you change the target rather than punch through or punch through to a different world, or to a lower ratio world
  6. Offline


    No, I haven't tried to destroy a existing portal :p

    I have 4 worlds:

    startup world

    Now I have in the startup world three portals:
    To world1,2 and nether.
    They are working.

    But for example in the nether, I can't use a portal, which is linked between startup and world1 (I wan't to get out there, too)

    What is my fault? :/

  7. Offline


    If you use punch through, it will destroy things in the way of the portals, except for other portals, in which case it will say it is blocked by a portal. If you want to have the portals next to each other like in the figure, you can use portal link command to circumvent this.

    Not sure what you mean here.

    cooldown is in milliseconds, sorry, should mention it in the OP.

    Sorry, my English is not the best...

    But I got it to work now.
    Thanks for your help!

    Last thing:

    possible to create a static download link for CraftBukkitUpToDate?!
    Would be great!

    Best greets


    Sometimes the plugin doesn't save my targets for portals :/
    Can anyone help me?
  9. Offline


    Does it show up in targets.txt?
    Btw, I'll try to get that static link up

    That's some good ideas, I might add an ability to have permissions bound portals.

    Hmm, in my NetherPortal folder are only:


    Where do I find a tragets.txt?



    Thanks for static download links!


    I get this error, if I use /setspawn in a world:

    2011-04-16 14:36:30 [SEVERE] Nag author: '<NoAuthorGiven>' of 'NetherPortal' about the following: onPlayerCommandPreprocess has been replaced with a new signature, (PlayerCommandPreprocessEvent)
  11. Offline


    Never mind, I wasn't thinking. The fifth field in np_portals.txt should give you the target portal id (the line at which the portal is stored in the file) Maybe you could upload it and tell me which portals should be linked.

    Yes, I noticed that one, its removed now. A leftover import caused it of all weirdnesses.

    Here is my np_portals.txt:

    I would like to have the targets:

    startnether -> netherneu
    startalt -> altneu
    startneu -> neualt

    (Sorry, the names of the worlds and portals are German, I hope you can help me anyway.)

    But a BIG thanks, for all your quick answers & great support!

    portal settarget startnether netherneu
    then open the file again and copy it here

    but I get the strange error, that I have to rename all the portals first :/
    Did this & tested, it works,
    but sometimes after a restart the target from the start world is missing.

  15. Offline


    settarget does it only one way. If you want to travel back the same way you have to use portal link. Does it really say you need to rename the portals or just name them?
  16. Offline



    now everything is working for me - I tried a other solution.

    After a restart, I clicked a portal - the name is still the old -, but I can't link/settarget the portals, because NetherPortal says, that a portal with that name doesn't exist.
    So in short: After a restart, the linkings are still working, but the names are somehow gone...

    So and now to the linking and settarget:
    I'm going to list what worked and what not!

    I linked two portals (eg. 1 & 2)
    I have a third portal in another world (3)

    I tried to /portal settarget 3 1
    It worked, until I restarted the server, then the linking of 1 & 2 was still there, but not the "one way" from 3 to 1

    Now I built a extra portal and only linked portals.
    After a restart the linkings are still there :)

    Maybe it's a little bug you can fix - but now all is working correctly and I can play with my friends!

    A BIG, BIG THANKS for all your support, quick solutions & the static download link!

    Thanks for the bugreport. I think I know what the problem is now. The original portal file loading code was written under the assumption that they are only two way links. So one way portals work but after reloading, some one way links will drop. Will be fixed in next update.
  18. Offline


    Apparently only occurs when you have portals that don't point anywhere. Fixed now.

    I just tried 709 and haven't had a problem yet. Those spammed errors typically occurs due to prior errors either in player connect event or more likely the onenable (at startup.) Could you have a look in server log and see if there was such?

    No idea, I use neither atm.

    I found a new bug:

    Sometimes (but only at this special portal!) I am teleported, but I'm two blocks under the portal!
    The Portal ins in the middle of three portals - could that be the point?

    Hi guys

    i think its just me being stupid but how do u create portals?
  27. Offline


    Have you linked your worlds first? If you haven't linked two worlds with the "/world link" command first, nothing will happen. Par example, if you have two worlds, "world" and "nether", link them with "/world link world nether" and now any portals made in either world will lead to the other.
  28. Offline


    ive linked the worlds and found a spot where i get the right configuration of "X's" with the compass, i built a portal from obsidian like in ssp but nothing happens.
  29. Offline


    What is all about 'Portal creation not authorized' message? Do I need a some setting to be set on my server for ordinary user can place a working portals?
  30. Offline


    You need to set the permission NetherPortal.portal.create for the default group

    If you do not even get any error messages then it is probably bukkit reporting the portal blocks are air. To bypass this you can set artificialportal=true in the config file.
