That may work

 

True....

 

I've added the first solution to the original post. I'm still up for more ideas since this solution does work but surely there should be alternatives. More solutions are needed since hidden rooms that can't fit in a 1 wide slot are unable to be created and of course Obsidian isn't the cheapest material to obtain and move around - on ORG at least.

 

You could try and use tp to get in and out of your building. Place something you can teleport to inside your building and completely wall off your entire building/structure.

 

or maybe the fact that you cant die on other people's islands with island protection... just a thought

 

so uh, my question is.... how does the OWNER enter?

 

Breakable block from the top. Just break your own way in from the top - maybe have a wool block or easy to break and place block there.

 

I have come to realize you can place Nether Portals adjacent to one another. So I made this demonstartive 5x5 protection room version for you all to admire:


I guess you could say I'm thinking with Portals

 

I don't quite understand what you're trying to get at... 1. Can't obtain/place bedrock. 2. Can't currently /setwarp - if this isn't what you meant by "spawn" then I have no idea. 3. Only mods have tp perms. Unless you broke a wall each time, placed an alt inside and used them to tpa it would not be possible. 4. "Completely wall off your entire building/structure" - how? That's what we're trying to work out, how to build a structure that is secure e.g. cannot get inside using /jump, /fly and /god.

The nether portal idea is interesting. I was about to suggest you just make portals next to one another but you already worked it out I don't know though if it would be too laggy to be a good solution. On the last server I admined on we had to disable nether portals for lag reasons and create public ones for people to use/only allow them by special request I don't know if the same amount of lag is created if the portal isn't actually connected to the nether but it would not surprise me. I might use the design above to make a very small safe room to keep some back-up sheep in, then make a room similar to gnollmar's first one that's tricky to get into but not impenetrable. If someone does kill all the sheep it would at least be possible to repopulate them by breeding if some were kept in a "safe house". Not an ideal solution but a good chunk of the way there I would at least be happy to start a sheep farm with this model! Thanks Hk x

 

you can make a flat netherportal too, but well, max size of a portal is 21*21 portal blocks (inside a 23*23 frame. )

This makes a 441 grass sheep farm possible, its not perfect, but well, its safe though ... the price of the obsidian, without redstone to obsidian plugin ...

 

True, yet never forget you can stack up the layers to save on Obsidian. Would be pretty neat if you organized your sheep farm by colours using layers x) I mean, that'd just be awesome.

 

Can't they just remove the jump command? If it's causing this kind of trouble, I say remove it.

 

People paid for the jump command and it has a lot of positive uses in and around itself. If anyone abuses the command they can simply be punished for it.

 

Hoppers also have a lot of positive uses, didn't stop them from being disabled just in case someone might think about abusing them. From what I hear though, they can't figure out who abused the command so no one will be punished for it.

 

Hoppers and the /jump command are Apples and Oranges. They are two completely different issues. The most important distinction is the /jump command won't ruin the economy or completely lag out and crash the server in a day. With the mass Hopper duplication glitch and the amount of lag they produce the server will be fried in potentially minutes.

 

Just keep this in mind.

 

Another problem with this is nubs /tpa ing their friends to the livestock or what may be a locked island.

 

Since no one should be able to get into the farm in the first place if it's designed like this, the only risk is if the owner places them in.

 

how does the owner get in door, breaking block, idek

 

I thought to create some quick visual stuff for you.
So this would be your final thing:


Where the Grass is, you'd have your secret rooms or animals.

On top of it all is just a simple platform and define which block I break, I placed a wool block - as those are easy to get and easy to break-



After breaking, a ladder is revealed and your secret chamber is temporarily accessible.

Once inside you just fill the hole(break it when you want to get out or /home)
