You seem to have found a spawn egg. You can use it to spawn the type of mob the egg belongs to.
To use the egg you simply right click on the ground while holding the egg in your hand it then spawns the mob at the location you clicked on.
The official description as on the minecraft wiki:
A Spawn Egg is an item that may be used to spawn mobs directly. It ...
If you use the JDK instead of the JRE then you can use the following command line to force the JDK to use all available cores for optimising Java itself (source):
-server -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:+CMSIncrementalPacing -XX:ParallelGCThreads=7 -XX:+AggressiveOpts -Xms1G -Xmx8G -jar craftbukkit-1.4.7-R1.0.jar
As you are clearly using ...
Spigot is a fork of CraftBukkit and implements the same Bukkit plugin API, and is designed to be a drop-in replacement for CraftBukkit.
The advantage of Spigot is extreme configurability. If you know what you're doing, you can see a 50% drop in RAM and CPU use. But that's a big if – since you're asking, you should probably assume that the extreme ...
You can use the very simple (yet effective) WhichMobs plugin, to explicitly turn off certain mobs from spawning. All it would take is a simple ghast = false in the property file for the plugin to turn Ghasts off. You could also use NoSpawn and MobToggle, all of which accomplish the same thing.
Also, if you would like to keep Ghasts floating around but at ...
You can vastly improve the performance of your times using MATHS.
You can see the principle outlined in another answer (this answer deals with redpower timers, but the principle is the same, you just need to do it with your vanilla timers instead). All you need to do is set up multiple timers, like the one you have there, but with coprime numbers of ticks (...
There's a relatively simple command block solution to this, which works in vanilla.
First, set up a scoreboard objective to detect players in the Nether
/scoreboard objectives add onNetherCeiling dummy
Create a clock (I suggest using a fill clock) in your spawnchunks (so that it is always loaded), hidden in a box of Bedrock, and add the following three ...
Due to there not being any plugin that currently does this, I have developed one.
It is called MobLocator and can be download here.
/mobloc shows the number of each type of mobs that are present in the world.
/mobloc [mobType] shows the location of the 10 closest mobs of type mobType. (Using euclidean distance). Note, you can use a mobType of ...
Only ops are able to program command blocks, so that should narrow the list of suspects. Some (virtual) face time with your ops should reveal the guilty party.
In the meantime, if your map doesn't rely heavily on command blocks, they can be disabled by setting enable-command-block=false in the server.properties file and restarting the server.
To locate the ...
OptiFine has, among many other improvements, a clear water option (under Video Options -> Details). This is a pure client modification and works just as fine in SMP. (Note that this is not compatible with MCPatcher, which is however not needed since OptiFine also includes HD texture support).
The number is set from the server.properties file and can be as large as you like as long as the server has enough bandwidth and memory to hold all the people.
If you're asking about a particular server, the maximum number of connections can be seen from the server list in game.
PermissionsEx and ModifyWorld should solve this problem quite nicely.
PermissionsEx is a general permissions plugin and ModifyWorld is an optional part of PEX:
[ModifyWorld] provides the possibility to control players
abilities, such as destroying/placing blocks, riding carts/boats or
even getting spotted by mobs and much more. Disabled by default.
Though an answer has been accepted, I needed some additional steps to make this work. I also wanted to import The End (which didn't exist when this queston was asked and answered). So here are full, updated instructions for others with this problem.
Note: I installed Spigot rather than Bukkit. Spigot is a speed-enhanced fork of Bukkit, and the same ...
You want to use Multiverse:
Create multiple worlds of different types, seeds and with Custom Generators
Create portals to let users go between other portals, worlds, or locations
PermissionsBukkit support (Anything that implements the superperms api - GroupManager does I think)
iConomy, BOSEconomy, RealEcon, Essentials Econ and Item economy support!
Well, as it turns out, /sp is just an alias for /superpickaxe. You could easily change this to anything else. Just open the WorldEdit.jar with any ZIP unarchiver and edit the plugin.yml file that's inside. It's a large file, so just do a Ctrl-F and search for 'superpickaxe' to find what you're looking for. It should look like this:
Quite the contrary, it seems really easy to do with MCEdit (I've just tried it).
Start MCEdit, create a new world. Put in a few numbers - how large a world do you want to have?
Once the world is generated, press ctrl + a. That selects the whole world.
Select the Fill tool. Pick stone and pres fill.
Similarly, fill the bottommost layer with bedrock. (set ...
Bukkit does not update for snapshots. You cannot run a Bukkit server on anything except a primary release. Unfortunately, you are out of luck. You'll have to run a vanilla server or just wait for the next full version to be released.
So far, I discovered a nice solution. I had to make a splash Potion of harming II. Then I approached the farm without looking at it (like while you play slenderman). It seems that Minecraft renderer is smart enough not to lag completelly when you do not look at the laggy area.
I've released a CraftBukkit plugin called DropProtect which does almost exactly what you're looking for. It protects all Armor slots (Helmet, Chestplate, Leggings, and Boots) as well as the 9 hotbar slots by default. It is configurable, so you can change the number of slots that are protected.
Before and after death with 9 protected-slots (covers the hotbar ...
Currently, the random ticks only happen within the 16x16 chunk area around the player. That means even keeping the chunks loaded doesn't help if there's nobody within the radius.
The common vanilla approach is to move the farm near frequently visited areas, where players' presence will keep the farm active. Alternatively, just afk near the farm to keep it ...
I can't believe no one commented on Opis, by Professor Moebius: http://www.minecraftforum.net/topic/2104497-164server-admin-opis-112-alpha-now-with-entity-support/
This is a server side Forge (and client side for the admins) mod, and if you have option to use it (turn a vanilla server into a Forge one, or a Bukkit server into a MCPC Plus one), this is THE ...
I just wrote a quick plugin that will do this for you. It's called StartingItems, and you can find it on BukkitDev here. It supports both respawn items and items for players that first login. Feel free to check it out.
If you have protected (uneditable) blocks, you can build this as a redstone mechanism.
Start with a long-period clock (there are several ways to do this), 5 stone pressure plates, and a dispenser. Construct the logic circuit not(or(edge-detector(clock), not(plate), not(plate), not(plate), not(plate), not(plate))) and connect it to the dispenser.
You don't need to use any mods – a lot of the information is already given to you simply by hitting F3 and reading all the confusing values.
The E value stands for Entities. My game is currently showing E: 7/68. This means that there are 68 total entities in the chunks currently loaded, and 7 are on-screen (if you could view through blocks). Now, the term "...
