NBTExplorer is a low-level graphical NBT data editor similar to, inspired by, and based on NBTedit. The key difference is NBTExplorer's full support for Minecraft .mcr region files, and a directory-tree interface for easily exploring multiple worlds. NBTExplorer is built on top of Substrate.

NBTExplorer can read:

• Standard NBT files (e.g. level.dat)
  
• Schematic files
  
• Uncompressed NBT files (e.g. idcounts.dat)
  
• Minecraft region files (*.mcr)
  
• Minecraft anvil files (*.mca)

Windows Users
NBTExplorer is a Windows .NET application, and requires .NET framework 2.0 to run.

Linux and Mac Users
NBTExplorer has been tested for compatibility with recent Mono runtimes, and should be compatible with both Linux and MacOS X by running it with Mono.

Since this a new tool, there might be bugs. I recommend backing up worlds before modifying them with this tool.

[Davve]

Meh, wasn't planning on finishing mine anyway.

[Razeredge]

Looks good!

Only two posts?
I think people are getting too stond of their comfort and user-friendlyness.
Gratz to you for making this!

Thanks for this program

Thanks a lot for making this!

Our biomes in QuestWorld where changed through MC 1.1, this program helped me fix it

NBTExplorer has been updated. Rough changeset:

- Project retargeted to .NET Framework 2.0
- General usability improvements
- - Open folder dialog remembers your last position
- - Files and folders can be dragged into the window to open them
- - Files and folders can be dragged onto the executable to open them at launch
- Improved Mono support, tested to run under both Linux and MacOS X (as always, YMMV)

Nice job with this. <3

[Mr.OMG]

umm....Can I change weather with this?like disable it or remove all snow?or an option to make raining like 1 second so it doesnt matter

[jaquadro]

No, that requires a mod. If you're looking to physically remove all snow blocks, a block replacement tool can do that for you. There's several around.

I still don't understand why this thread haven't got crapton of replies. Nice tool, i use it all the time!

[jaquadro]

NBTedit is still a good tool for most people, and even that's pretty low level for the average player. Chunk editing is a niche requirement and most useful to developers. That's okay.

Can anyone tell me (if even possible) what i would need to edit in my level.dat with this program in order to make this appear as a fresh start world even though structures and features have spawned in it?

The purpose is to use an existing World with the "Tale of Kingdoms" mod. I have moved my spawn point to where i want the Mods building to spawn, but the mod will only spawn them on new worlds. So to sum up... how can i make my old world new without deleting all the progress i made on it? Is that even possible?

[mandog15]

Cool

I have a question, I have a diamond sword on a world in minecraft, I want to edit it to have enchantments, how?

That largely depends on how the mod determines new-world state. If it goes off of an attribute like TerrainGenerated (which is used by Minecraft to determine when to populate chunks with trees, ores, etc.), then you could reset that flag, although it may have negative effects on your chunks. If it hooks into the routines that actually create chunks, then you'd need to delete the chunks where you'd like it to spawn. If it somehow hooks into the code that first creates a world, then I'm not sure there's anything you could do.

You can add the necessary tags to your items to give them enchantments. Check http://www.minecraft...le_Format#Items for the exact tag hierarchy needed -- enchantments are rooted in the "ench" compound tag. If you have enchantments on any of your items already, then you can look at those in NBTExplorer and use them as a guide. If you look around the tools forum, there are also tools specifically to edit enchantments that are probably easier to use.

Thanks for the response. Ultimately i think it's just time to start a new world and enjoy building it up anew.

NBTExplorer has been updated for Anvil map support. The set of NBT tags was expanded in anvil to include int arrays, which are now used in the .mca region files.

[mandog15]

I use NBTedit aswell as NBTexplorer, NBTE (nbt explorer) has a nice interface and more options.
NBTED (NBT edit) is simple has good options and clean.

Use NBTED for your first time then use NBTE.

I am surprised this hasn't gone over 1 page.
Though I only ever use these fine tools to extend my health on my gold sword (I got all the XP and enchants legitly, fire aspect V looting V knockback IV and I cheated this last one sharpness 10)

So I do not want to lose it

[jddevos]

this looks awesome!

[jaquadro]

NBTExplorer has been updated, adding a (read-only) hex editor for viewing the contents of byte array and int array tags. I'll extend this for read-write support later, but for now it was just critical I be able to read the data to verify the changes I'm making to Substrate.
