Talk:Chunk format

Deleting Chunks
Hi! I was wondering about getting chunks to re-generate - can I just delete the folders for outlying chunks, then have them re-generate by the engine? I guess the question becomes, are chunk files referenced by any other dat files?

 * With pre-MCRegion format files, all you have to do is delete the folder for the chunk. With pre-Anvil and Anvil format files, there are many chunks within each region file and you have to use a program like MCEdit or NBTexplorer to delete specific chunks. LB 20:13, 21 June 2012 (UTC)

Confusing format
I find some parts of this page confusing, specifically missing type specifications. For example, what's a TAG_Compound? What's its structure? and other questions.

Anyone could make this page clearer when it comes to types?

 * See Development Resources where it says "Notch's notes on NBT format files.", that explains the TAG_Madness that you see. LB 20:11, 21 June 2012 (UTC)

InGround tag
Could someone confiirm/disprove the fact that the InGround field of arrows, eggs and snowballs controls whether or not the entity is stuck in the ground? I think a tag is missing from the three types of entities controlling what I just said because the entities act differently depending on whether or not they are stuck in the ground (for example, eggs and snowballs disappear if they become stuck in the ground, and arrows stop moving and don't do damage when stuck in the ground).

 * I have personally checked all projectile types, and they all have just those tags plus the entity base tags. LB 20:09, 21 June 2012 (UTC)

Entity format
I never seen TAG_String("World") in any entity. I tried all version since Beta 1.2_02. Could someone confirm this tag?

 * I can confirm that it doesn't exist; I've checked all known entity types. LB 20:15, 21 June 2012 (UTC)

Move to Chunk format
I agree. The info applies to Alpha, Beta, and Release formats. It looks kind of odd being the only subpage under Alpha Level Format. -Codewarrior 12:17, 1 December 2011 (UTC)

Missing entityes
The entityes section misses the folloing entityes:

Blaze Magma cube EnderDragon Mooshroom Snow Golem Villager Endercrystal Darksonn 18:30, 8 January 2012 (UTC)


 * I added EnderCrystal but it has all the same tags as the base Entity. I put it in items because I wasn't sure where else to put it. LB 20:08, 21 June 2012 (UTC)

128 or 256
Are they in 16x128x16 or 16x256x16 since the last update???


 * Neither. See Anvil file format. This page is now out of data, although I want to pull in changes from the Anvil file format page here. --Thvortex 21:37, 8 March 2012 (UTC)

Merge with Anvil file format
Can we merge the Anvil file format page into this one? This page is a lot more detailed. We could also include a link on the this page that pulls up the older version of the page so one can still easily find what the previous chunk format looked like. --Thvortex 21:35, 8 March 2012 (UTC)
