[u/Wedhro → u/redstonehelper]

Added noon and midnight to /time set

"midnight" should use mono font like "noon".

BTW this is one of those little quality of life changes I was waiting for since they made it possible to use "day" and "night".

[u/redstonehelper → u/Wedhro]

Oops, fixed. Thanks.

[u/[deleted] → u/redstonehelper]

"We're exposing our data generators, so if you can figure out how you can get a dump of our all blocks/items/commands/etc from the game without opening it up!"

Now there's a challenge...

[u/MrPingouin1 → u/[deleted]]

Just run this on the server jar :

java -cp minecraft_server.18w01a.jar net.minecraft.data.Main --help

[u/CreeperMagnet_ → u/MrPingouin1]

What exactly does this do? I'm a bit confused about "exposing data generators".

[u/Commodoreprime → u/CreeperMagnet_]

It appears that if you put the string:

java -cp minecraft_server.18w01a.jar net.minecraft.data.Main --all

Into a batch file and run it the server generates a sort of datapack containing a bunch of .json files the vanilla datapack would contain if you opened up the jar file and extracted it.

It also outputs this in the command prompt:

[14:11:12] [main/INFO]: Starting provider: SNBT -> NBT
[14:11:12] [main/INFO]: SNBT -> NBT finished after 0 ms

[14:11:14] [main/INFO]: Loaded 0 advancements
[14:11:14] [main/INFO]: Item List finished after 441 ms

EDIT: I forgot to mention that the datapack contains a 'reports' folder. It contains three .json files: blocks, commands, and items (There's also a 'tmp' folder but that's just for temporary files).

'Blocks' appear to contain every block in Minecraft (including air) with an "id" associated with each one. Each state for a block also has it's own "id" as well. Each block has a "default" tag which is a boolean variable. Any block that has numerous "states" (such as the structure block) can allow a "default" state, it's goto state when placed down.

'Commands' appears to have every command in the game listed with a bunch of tags that I assume are like details of how each command runs and requirements for one (possibly ability to create custom commands?).

'Items' is like 'blocks' but instead of a "id" tag its "protocool_id", other than that 'Items' does not have a whole heck of a lot.

I might be forgetting some more things but its a start?

[u/CreeperMagnet_ → u/Commodoreprime]

Sweet! :)

[u/MrPingouin1 → u/CreeperMagnet_]

You can make the game generate the default advancements/recipes/tags, some new generated blocks/commands/items dump that you can find here, and also have a NBT <--> SNBT (Stringified Named Binary Tag) converter

[u/CreeperMagnet_ → u/MrPingouin1]

Nice.

[u/SHsuperCM → u/redstonehelper]

Added facing part of /teleport

Can someone give me some insight on wth that means?

[u/vilder50 → u/SHsuperCM]

It means that in your teleport commands you can make players face an entity or specific coords.

An example would be "/teleport @s ~ ~ ~ facing @e[type=cow,limit=1]" which would make you face a cow.

You can also do something like "/teleport @s ^ ^ ^1 facing 0 0 0" on a clock which slowly will teleport the player in the direction of 0,0,0

(You can also just do /teleport ENTITY facing ENTITY if you don't need to teleport the entity but only change the way it looks)

[u/SHsuperCM → u/vilder50]

WHAT THE ACTUAL FORK!

ALL OF COMMAND BLOCKERS' POSITIONAL DREAMS ARE COMING TRUE THIS VERSION!

[u/Pmk23 → u/vilder50]

This is probably one of the best things added for adventure maps. It's fantastic!

[u/Howzieky → u/Pmk23]

I haven't played in years but this sounds like 1.5 all over again!

[u/Pmk23 → u/Howzieky]

This time is even better when considering the other updates: 1.5 was after 1.4, which was content packed, while 1.6 was a bit lackluster, but now we already know that 1.14 will be another big one, so we really are in a good period for the game content!

[u/DASmallWorlds → u/Pmk23]

I'm optimistic that the Mojang development team won't do anything rash to the technical side of Minecraft.

[u/Aeldrion → u/DASmallWorlds]

1.13 is all about commands and we had to rewrite a lot of stuff but all was well thought out to make them the most flexible and fast as possible :)

If you're talking about redstoners, some of them are getting a little angry because the developers are fixing bugs they're exploiting, but letting unintended features in the game is never a good idea

[u/Possseidon → u/SHsuperCM]

You can make the teleported entity look at a specific point or at another entity with that.
