[TP][FUN] NetherPortal - Multi World Fast Travel with a challenge v0.6.10 [803]

NetherPortal v0.6.11

New in Version 0.6.11:

• Added NetherPortal.portal.use permission

Description

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:

Code:

 XX
XXXX
 XX

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:

Code:

  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.

Try again, I forgot to change the link so it pointed to 0.5.2.

 

So far so good. Thank you.

 

I don't understand how to build a portal. Can someone give me a screenshot or something?

 

You build it just like in single player with 5x4 frame of obsidian and light it with flint and tinder.

 

Hi

This plugin sounds like exactly what I've been waiting for.

I use a border in my normal world to prevent people creating new land but I've never been able to have a nether since people could teleport back outside of the border upon returning to the world. Am I right in understanding that your plugin lets you set the ratio for distance moved in the nether, so I could create the same exact border in the nether and not worry about people teleporting back into the other world outside the border?

I'm assuming that CMD_world_ratio=world ratio is the config value that controls this, but how do I configure it?

 

Actually that is to configure the command so you can type something else to change the ratio. You can set the nether ratio to 1 with "world ratio nether 1" if you have named your nether "nether". Alternatively if you want to keep fast travel, you can have the border 8 times smaller in the nether.

 

my world border is only 2000 so it would be a pretty small nether

so doing /world ratio nether 1 in game will set it to be just like the normal world?

 

Yes.

 

Wonderful, thanks for the quick response

 

I really like the look of this mod. The only thing that is stopping me form using it atm is the not respawning in the normal world. Once that's implemented I'll start using this. Just one question though, I already have a nether world set up. Can I just point the mod to use this world instead of generating a new one?

 

Yes, world create will import the world. I was going to implement the respawn in normal world thing, but forgot about it, good thing you reminded me.

 

Whenever half of my players (including myself) try to go into one of the extra worlds we get this error:

2011-03-23 01:14:52 [WARNING] Can't keep up! Did the system time change, or is the server overloaded?
2011-03-23 01:15:00 [INFO] (The Players name is here) lost connection: disconnect.overflow
2011-03-23 01:15:02 [WARNING] Can't keep up! Did the system time change, or is the server overloaded?

and get disconnected within a minute of going through the portal. Any help would be much appreciated.

 

Never had this. Did a search and found this: http://getsatisfaction.com/mojang/t...nect_overflow_after_few_seconds_on_the_server
Maybe it is a related problem and sending all those chunks on teleportation hogging up bandwidth. Does this occur with any other teleportation plugins?

 

That could very well be, I've noticed that it mainly affects the people with slower internet service. It does not happen with any other teleportation plugins though.

 

I try to link the world and nether with /world link world nether and I get the error "World by name world doesn't exist" even though I'm clearly in the 'world' and it shows up on the world list.

And my portals don't work anymore...

I guess it was because I was on Bukkit #567

 

Does it work with 556? I only intend to support the latest recommended build.

 

It works for 556 yes, but it was broken when I upgraded to 567.

 

Hey i have got a problem.
If I go into a portel I get the message: The Portal refuses to teleport you!
So can you help me please.

 

That means the corresponding location in the target world is not suitable for creation of a portal without destroying blocks and/or adding a platform. If you still want to create it there you can type: portal punch through to <world name>

 

Thank you very much it's works perfectly.^^

 

Tried 0.5.4 and after destroying one block of a portal it collapsed as expected, but walking into where the portal blocks were located still gives me the message "The Portal refuses to teleport you". This disappear if I /reload.

Also, an idea for those who want to use the plugin as intended, i.e. no punch through: if you build a portal that'll refuse to teleport you, it could collapse right away. It's one less immersion-breaking text message, and it saves the trouble of deconstructing the portal.

The yellow X instead of 80000 is a nice improvement by the way.

 

Thanks for reporting, fixed. Regarding your idea, there has to be some penalty for building a portal in the wrong place, and I've reduced that penalty 10 times already by allowing portal collapse so I think it should be ok as it is.

 

Just tested it, it's awesome.

Only thing, can you add iConomy to it? and charge users to user it?

 

I'll see if I can do it.

 

/world create nether nether doesn't works on bukkit 556. Just nothing happens. Yep im in ops and have all of the permissions manually added.
im currently works with:
AuthDB
DeathTpPlus
Help
HeroChat
LWC
MyHome
MyWarp
Permissions 2.5.4
SignColours
SimpleSave
WorldEdit
WorldGuard
All of plugs works & they a up to date 556 build
So im trick the plug-in and manually create an two worlds : normal & nether.
But /world list doesn't type my new nether world.
Then im going further.... and saw a notice in cmd about np_worlds.txt
plugins\np_worlds.txt - should be the some kind of worlds lists?
Im need a some kind of template.
Maybe im just can add my nether world in list.

Notice: i'm had a bad english. sorry... hope you understand.

maybe a commands conflict?

Update: yep its one of plugins conflicts with the /world command
Im trying to change the command for the action but config.txt doesnt work.

old /np world create was great! Why you decided to make it without /np prefix?

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

This plugin works great so far, no issues to report!

A question however, how does the compass pointing work, exactly, when trying to find a spot to construct a portal? Does it just point to the nearest good location? Is this covered somewhere that I've missed?

Thanks asdaarg!

 

I removed the np prefix so you don't have to type too much by default. If it conflicts with something else, then my plugin allows you to change the command: CMD_world_create=whatever

The compass indication is a bit buggy, I finally found out, although it will be fixed in the next update. The compass gives a cold/hot indication, so walk toward bigger numbers. Try to find X. Read the first post for full explanation to get a guaranteed suitable location.

 

this download doesn't work for me i have the one for 544 but i now need 556 and i cant get the download to work...

 

I only intend to support the latest recommended version. If you have problems with it, you need to be more specific.
