Talk:Spawn/Multiplayer details

Page accuracy
This page seems to be accurate, I have found similar thing on my server when discovering the spawn point. Thing I would add as a note is that while spawn area is build, players seem always to be "born" in highest level of structure, so if you want to build house for spawning, for now you gotta leave roof off, because otherwise players will spawn on roof and not at intented place. That effect if not accounted can cause some unfortunate side effects. –Preceding unsigned comment was added by Arxroth (talk • contribs)&#32;04:05, 11 March 2012‎&#32;(UTC).

help me plz i am confused
On a superflat server, in server.properties, can you select where you spawn players. Furthermore, at the players original spawn point in my singleplayer superflat world, will multiplayer spawn players around the spawn point? I am trying to make a superflat world into a server, but w ill the town I made near my spawn be lost as the game makes a different spawn point, or not? --88.110.121.248 15:23, 26 June 2012 (UTC)

Protected area
On my server(mc1.2.3 craftbukkit2377)the spawn area isn't protected for the whole map height, just around ground level. –Preceding unsigned comment was added by 90.142.173.128 (talk)&#32;19:46, 1 October 2012(UTC). Please sign your posts with

Constantly loaded chunks question
Is the section about Constantly loaded chunks only relevant to SMP, or does it apply to SSP now they all share the same codebase?

I have an idea for a single player map that might depend on the answer to this...

Thanx in advance. --GufNZ (c: (talk) 08:46, 22 October 2013 (UTC)

Possible correction
I believe the constantly loaded area is actually 12x12 chunks (192x192 blocks), and not 24x24 chunks as it currently states. Can anyone confirm? –Preceding unsigned comment was added by MCGrayden (talk • contribs)&#32;18:53, 9 November 2013‎&#32;(UTC). Please sign your posts with


 * I checked the maximum chunks using the method on the page of moving the player far from the spawn chunks, deleting the spawn chunks, and reloading the world. Instead of 24x24, it turns out to be 25x25. Furthermore, within 16x16 chunks, redstone mechanisms are functional. Within 12x12, entities are functional. I currently have no idea what goes on beyond the 16x16 chunks, up to the 25x25 chunk limit, that is significant. Skylinerw (talk) 04:25, 30 December 2013 (UTC)
 * Yea, the page will need to be re-written. Checked the functional chunks, and it's 25x25 for 'unknown', 17x17 for redstone, 13x13 for entities. Hopefully somebody can figure out what the "unknown" is. This change must have been very recent, as the spawning chunk used to be off-set in the north-west direction, and now it's exactly in the center. Skylinerw (talk) 01:08, 2 January 2014 (UTC)

Possible Changes
I run a lot of test in multipleyer in 1.7.2 and the actual size of the spawn area seems to be 10 x 10 not 20 x 20. Please someone test this to confirm. –Preceding unsigned comment was added by 187.191.10.93 (talk)&#32;18:10, 7 December 2013(UTC). Please sign your posts with


 * Tested this in 1.7.4, I can confirm that the respawn area is 10x10 blocks. This was done on a flat surface, so I am unsure if there are differences with widely varied terrain. Skylinerw (talk) 04:07, 30 December 2013 (UTC)

New Information for 1.7.4+
This page has become quite outdated, thus is in need of updating. I am unsure of how much of this information needs to be fixed, but I can provide what I do know.

The above image shows the entirety of the perma-loaded spawn chunks. Each square of the grid is a full chunk (16x16 blocks). The RED grid (13x13 chunks) represents where redstone mechanisms and entities are loaded and functional. The BLUE grid (17x17 chunks) represents where redstone mechanisms will still function, but entities will not. The GREEN grid (25x25 chunks) is the last set of perma-loaded chunks, but I do not know what functions within this section. So the total number of spawn chunks is 25x25, while the viable chunks are 13x13 (allows for redstone mechanisms and entities to function).

The default "world spawn chunk" is the center of the perma-loaded chunks. The "world spawn chunk" is determined by the location of the "world spawn coordinates". These coordinates can be found through an NBT editor, or applied using the /setworldspawn command. The chunk the "world spawn coordinates" reside in will become the "world spawn chunk".

In the image linked above, to the right is a zoomed image of the "world spawn chunk". The YELLOW wool block represents the "world spawn coordinates". Since the yellow wool resides in that chunk, that chunk becomes the center of the perma-loaded chunks. The blue stained-glass is a 10x10-block area in which players will respawn around the "world spawn coordinates". These are tied to the coordinates, not the chunk. For example:

The chunk the yellow wool is in will still be the "world spawn chunk" and operate as you'd expect: it is the center of the perma-loaded chunks. However, the respawning area (blue glass) is still centered around the yellow wool, so players may respawn in chunks other than the "world spawn chunk".

When respawning, height nor existence of blocks seem to matter. The entire 10x10-block area can lead directly to the void, with a single block available, but the player will still randomly spawn somewhere in that area. If there is a floor and ceiling to the respawn area, the player will end up on top of the ceiling. I have not found the minimum height a ceiling can be before the player spawns beneath it rather than on top of it, if that's even possible.

 * I've produced a video for evidence of the changes, along with downloads for schematic and world saves. I still haven't figured out what the GREEN chunks in the image linked above load that's of significance. However, I can say that in multiplayer, no matter what height a ceiling is at, the player will be placed on top of it when they respawn. As well, the 10x10-block respawn area is for *multiplayer*. It becomes a 20x20-block area in *singleplayer*.

 * I'll be willing to update the page if nobody else wishes to.
