For those of you who run your own servers, I *MAY HAVE* found a way for this to work (albeit very sketchily) with Bukkit, or any other server software!
I absolutely love this mod, and, ironically, I posted a topic just yesterday asking if there were any server mods that could edit attributes such as a mob's target or its type (e.g. normal creeper vs. charged creeper) without having to use an outside program such as NBTExplorer. Upon finding this mod, I leaped with joy, then crashed to the ground after realizing that Bukkit and Forge aren't compatible.
At first, my thoughts were "Well, it would obviously work if I took the world from my server and put it in .minecraft/saves/, but then I would have to take the server down to add my changes, disconnecting everyone!" And of course, it would take a while, too.
Then, I wondered if there was some way I could copy the world to .minecraft/saves/ and somehow make the server software run with that map. I arrived at two solutions:
1. The more obvious solution is to run the server from .minecraft/saves/ and open up your world in singleplayer. Minecraft would think you are playing SSP, but the server would be using that map also. I'm unsure as to whether you could still issue chat commands, but, long story short, you could do anything to the world file with mods in singleplayer, yet still have those changes saved to your server's map file.
2. In case you don't want your saves folder cluttered up with server paraphernalia like I do (I use Bukkit, so there are even MORE files!), you might settle for making a symbolic link from your server map folder to your .minecraft/saves/ folder. I already had the software installed, but long story short, you can create horrible filesystem holes and portals, so to speak, by making programs believe a single file or folder is in multiple places, or maybe contains itself. There are different levels of tomfoolery, with symbolic links being a sort of folder shortcut, and hardlink clones which can crash programs if you don't do it right. There's a nice little guide here which gives you a few bits of software with which to accomplish this feat, and detailed explanations (it also works with Linux!).
I only figured this out 15 minutes ago, so I haven't finished experimenting, but I have doubts as to how well this will work if you either method while others are on your server - I suspect there would be some sort of error because two processes are essentially using the same file. My server didn't like it one bit, and spat long errors at me, but when I joined it proper without going through singleplayer, the changes I had made were there, so I think while there may be some limited functionality, not everything will work. Have fun!
Just tested it with someone else on the server, it doesn't work if you're not the only one. Sorry!
TL;DR: I found a sketchy way to make this work with Bukkit, but it's probably unreliable doesn't work if you're not the only one on the server.
Davidee: Would it be possible for you to make a Bukkit plugin like this? I'm sure it would be greatly appreciated by lots of people, not just me.
What characters do you want special buttons for? Just the newline character and section sign?
Character? You mean...oh. Maybe a color selection so that we dont have to type in the color code, we just click the color icon. Maybe also an Command Block Text extender, to make the text box bigger. Also, options for bold, italic and crossed
Ill come with new suggestions soon
sry for not replying soon
Well I mean by like being able to freeze a item's amount. It would be useful for map-makers who want to make dispenser with infinite arrows or mob eggs. You could be able to freeze id's of items aswell to make infinite buckets filled with either water or lava and maybe even freeze the damage of somthing to use it a as many times as you want. I use a mod called industrialcraft and items have a string thats holds how much charge they have, you could also freeze the charge to.
EDIT: maybe you could do something like this :
Count : XXX
IsFrozen : 1
Slot : XXX
Damage : XXX
IsFrozen : 1
id : XXX
IsFrozen : 1
etc... also try making it work for string's in tags
Hi there Davidee, I've got a question to ask, is there anyway to add a button to bring up the list of things you can add as parts of an NBT thing such as mobs or blocks as a GUI ingame? By this I mean it shows what you can add for each mob, block or weapon when you press it, this is just a suggestion. I hope you might consider this or a similar idea sometime.
