Minecraft Snapshot 17w43b

We do not plan to add any new gameplay features or mechanics to 1.13. Instead we will continue to improve the game engine.



This first snapshot will introduce two major modifications to our codebase: data packs and LWJGL.





Data Packs


Usage & Installation

A data pack could be either or

Zip file

Or

directory

inside the folder /datapacks/. For instance, both these are fully valid data packs:



/datapacks/CoolPack2000.zip /datapacks/SuperPack3000/



If you obtain a data pack from a friend or on the internet, we usually think it will be a zip file. It will be automatically installed by placing it in the datapacksor folder.



The /reload command will apply any modifications to a pack of data that you've modified, installed or removed while the game is running.





FILE STRUCTURE

pack.mcmeta (Required). It is a description of the pack. This is a description of the pack. data/ - This is the reason it is an data pack, which contains all data files.Similar to resource packs, everything needs a namespace.Functions/ It contains all command functions.mcfunction A command function named :



.json A loottable with the name :



.nbt - A structure named :



.json - An advancement named :



.json - A recipe named :





Pack Hierarchy

Just like resource packs data packs have a load order. Unfortunately, there isn't a way to change or see this in the present. Sorry! We are working on it.





Note: Recipes?

? Recipes should totally be in data packs, but we haven't finished supporting this yet. That's why we don't currently look into custom data packs to find recipes, and we don't synchronize custom recipes from the server to clients.



They're not working yet. Soooooon!





Namespaces

Although this isn't an entirely new concept , it's important to know what "namespace" signifies. The namespace is used to identify game's various items. Mods, maps or other modifications can add new things, but they are distinct. When you're asked to identify something (e.g. the loot box) it is also necessary to specify the namespace it came from. If you don't provide the namespace, we default to minecraft. This means that something and minecraft:something are the exact same thing.



Always use your personal namespace for anything new that you add, and only use other namespaces when you're using something else to override. Don't try to add new things in minecraft generally.



A namespace should only contain the following symbols:



0123456789 (Numbers) abcdefghijklmnopqrstuvwxyz (Lowercase letters) _ (Underscore) - (Hyphen/minus)





Names of... things...

You can call anything (recipes, advancements, etc) whatever name you like however these are the only officially supported symbols:



0123456789 (Numbers) abcdefghijklmnopqrstuvwxyz (Lowercase letters) _ (Underscore) / (Forward slash, directory separator) . (Period) - (Hyphen/minus)



The preferred naming convention is lower_case_with_underscores.





LWJGL 3

We've finally updated to use the most recent version of LW

JGL

. This fixes a lot long-standing issues with Mac OS and Linux and should make it much more stable. The most significant benefit you'll get is that fullscreen mode now defaults to borderless windowed, so that switching into and out of fullscreen mode is incredibly fast! We've identified the following issues that you might face:



Fullscreen mode on Mac OS X is prone to crash hard. We have disabled it until we find an answer. There could be instances in the game in which key inputs are sent twice, for example pressing a hotbar while hovering over an object in the creative inventory search tab. - On Mac OS X, the game icon is no more a grass block. We are working on it!





Blocks to structure

When you use "save" in a structure block, it now saves it in the following location: generated//structures/
< p="">

When you use "load" in a structure block, we attempt to load from the generated folder prior to trying data packs. This ensures that loading and saving are consistent.



But, please don't distribute the "generated" folder by itself when you're creating custom maps. Convert it into the data pack. We are thankful!





Backwards compatibility - Time travel!

This is a challenge we all have to deal with, but we feel that we have to take action now to fix it.

We do not officially support the ability to go back to older versions of minecraft in the same folder in which you have a brand new version of Minecraft

. If you attempt to run this snapshot, and then return to an earlier version in the same directory then you will

lose all your keybindings

.



It is recommended that you run snapshots (and any other version than "the most recent release") in their own folders. This is, in fact, the reason why your tutorial toasts keep popping up ;)





A word of warning

1.13 will include a

Lot

Some snapshots that are experimental might smell odd and cause damage to everything. This could be one of the snapshots. This is what happens when we change everything!





Install the snapshot

Please report any and all bugs you encounter in Minecraft to bugs.mojang.com. If no one has reported bugs, we aren't able to fix it!



To get snapshots, open your launcher, then click the "launch options" tab. Save the box that reads "Enable snaps" . You can switch between the normal and snapshot versions by clicking the "Play" button. Backup your world first, or run the game in a different folder (in the "launch options") page.




Snapshots can cause harm to your home or your family. Make sure you backup them and/or put them in separate folders.
