TELEPORTERS

The Teleporters that go to the surface can be changed/removed if you wish to use a plugin or anything else, if you are using the command blocks though, you will need to place the log cabin:



At the surface (probably above where the cavern is) so people can access the cavern without using commands (If you do you commands that is). Just make sure to change the Coordinates in both the caverno s and log cabino s command blocks to the relative position



Instead of using a normal pressure plate to activate the command block, I have created a system that allows for vanilla player detection when standing in the log cabin. The spawner will spawn a fallingsand entity which falls & activates the tripwire which sends a pulse to the command blocks teleporting the play to whatever specified coordinates. The sand then gets destroyed by the half slab and burnt by the lava removin the entity to stop entity buildups that cause lag.

Also the trees/terraforming and such can be removed if you wish. Also a reminder, dono t forget to allow command blocks in the server settings if you are going to use them :)

Dynamic Lighting



This photo shows the way the dynamic lighting works, for the implementation of this you need to keep the daylight sensor at the bottom of the (Stone)tunnel and extend the tunnel to the surface where the grass is shown, and then there just has to be glass there. I would suggest using WorldGuard to protect this area to stop people breaking the glass and falling to their death.


Level

Be cautious about how far down the cavern is placed as if it is near bedrock it can produce depth(Void) fog

Note

All the villagers have been applied and Infinite Resistance 4 Effect which makes them invulnerable to attacks. So you will need to use MCEdit or another equivalent program that has the capabilities of removing entities if needed. This is simple on MCEdit, just select the entity and on the sidebar there is an option to o Delete Entitieso the entity marker should then disappear when this is done correctly.

Also, the villager trades can be edited using sethblingo s o CreateShopso MCEdit Filter (http://www.youtube.com/watch?v=13LyPP43twE)

I would suggest using the o Worldguardo plugin (http://dev.bukkit.org/bukkit-plugins/worldguard/) to keep mobs away and to stop players from breaking some of the technical bocks such as the invisible walls (as shown here:http://www.youtube.com/watch?v=Q1QLl14eQo0). They technical blocks are quite fussy about where they are and which way they are facing. It took a lot of time and effort to create them. They are also very prone to breaking when a Block Update (http://www.minecraftwiki.net/wiki/Tutorials/Block_update_detector) happens. Also try not to break 1 of them as it will cause the rest to break. Back to o Worldguardo , I have created custom Iron golems with Infinite Lvl 127 Strength and Speed. The golems kill any mobs that are within their range. However they also kill any humans who try to hit them which is not good for a spawn.They are also very buggy and dono t always attack the mobs. So using the plugin o WorldGuardo it can stop any mobs spawning in a particular defined region. (No you cannot do /gamerule doMobSpawning false because that would stop all mobs from naturally spawning throughout the whole server.



Another plugin that could be used is the o Citizenso (http://dev.bukkit.org/bukkit-plugins/citizens/) Which could replace NPCo s such as the o Refereeo o Cyprezzo and o Parilo . The citizens plugin can create a ghost player entity that can talk, walk, look around. They can also use a certain players skin or can use the default skin(Steve).



The final plugin im gonna suggest is a lift plugin, such as Lift (http://dev.bukkit.org/bukkit-plugins/lift/) or SignLift (http://dev.bukkit.org/bukkit-plugins/signlifts/). Or you could just stick to the command blocks, oro ¦ im gonna say it, plain old ladders. (or stairs for that matter!)
