Fabric Modding Tutorial - Minecraft 1.20: Custom Loot Tables | #5

Summary

This video tutorial covers how to add custom loot tables to blocks in a Minecraft mod. Loot tables dictate what items drop when blocks are broken, or when chests or entities are interacted with. The tutorial guides you through setting up JSON files for loot tables, managing conditions like block destruction from explosions, and tagging blocks for tool requirements. It also covers ore block settings, including experience drops, and ensures blocks are minable with the appropriate tools. The video concludes with in-game testing of the custom loot and ore blocks.

Q & A

What is the primary purpose of loot tables in Minecraft modding?

Loot tables in Minecraft modding determine what items are dropped when a block is destroyed or what items are contained within chests in certain structures, as well as what different entities drop.

How do you create a loot table for a custom block in Minecraft?

To create a loot table for a custom block, you need to create a JSON file within the 'data/<modid>/loot_tables/blocks' directory, with the file name matching the block's name. The file specifies the items and conditions for the block to drop.

What are the steps to ensure a custom block drops items in Minecraft?

To ensure a custom block drops items, you must add the loot table to the block, and then add the block to a specific tag that determines whether it can be mined with a pickaxe, axe, shovel, or hoe.

Why is it necessary to add a custom block to a tag in Minecraft modding?

Adding a custom block to a tag is necessary to define the mining tool requirements and the conditions under which the block will drop items, such as whether it requires a specific tool tier or can be mined without a tool.

What is the 'needs_tool_level' tag used for in Minecraft modding?

The 'needs_tool_level' tag is used to specify the minimum tool tier required to mine a block. It ensures that the block will only drop items if the correct tier of tool is used.

How can you make a block only mineable with a specific tool tier in Minecraft?

To make a block only mineable with a specific tool tier, you add the block to a 'needs_tool_level' tag corresponding to that tool tier, such as 'needs_iron_tool' for iron tier tools.

What is the difference between 'minable' and 'needs_tool_level' tags in Minecraft modding?

The 'minable' tag determines if a block can be mined with basic tools like a pickaxe, while the 'needs_tool_level' tag specifies the minimum tool tier required to mine the block.

How do you duplicate a loot table for multiple custom blocks in Minecraft?

You can duplicate a loot table for multiple custom blocks by copying the existing JSON file and renaming it for each block, then adjusting the block names and any specific values within the JSON file for each block.

What is the role of the 'experience_dropping' block in Minecraft modding?

The 'experience_dropping' block in Minecraft modding is used to define how much experience is dropped when the block is mined, allowing for customization of the experience gain.

How can you customize the amount of experience dropped by a block in Minecraft?

You can customize the amount of experience dropped by a block by using the 'experience_dropping' block type and specifying a 'uniformintprovider' with the desired minimum and maximum values for the experience range.

💾 Introduction to Custom Loot Tables in Minecraft Modding

This paragraph introduces the concept of adding custom loot tables to Minecraft blocks through modding. Loot tables determine what items are dropped when blocks are destroyed or what items can be found in chests within certain structures. The tutorial aims to add custom loot tables to a mod's blocks and then add these blocks to specific tags to control their behavior when mined. The process involves creating a 'loot_tables' directory with a 'blocks' subdirectory and naming the JSON files according to the block names in the mod's 'modblocks' class. The JSON file for a 'Ruby_block' is outlined, which includes a loot table type, pools, conditions, and entries that define the item to be dropped. The importance of matching the JSON file name to the block name in the mod is emphasized.

05:00

🛠️ Setting Up Loot Tables and Tags for Block Mining

The second paragraph delves into the specifics of setting up loot tables for ores and the necessity of adding blocks to mining tags. It explains how to create JSON files for different mining tools such as pickaxe, shovel, and axe, and how to specify the mining requirements for each block using tags like 'needs_iron_tool' and 'needs_diamond_tool'. The tutorial demonstrates how to adjust the mining requirements for different block types, such as making a block only mineable with an iron pickaxe or a stone pickaxe. The paragraph also covers how to create directories for tags and the importance of placing the correct JSON files in the appropriate directories to define the mining capabilities and requirements for the custom blocks.

10:04

🔩 Advanced Loot Table Configuration and In-Game Testing

This paragraph focuses on the advanced configuration of loot tables for ore blocks and the in-game testing of the custom blocks' mining and dropping behavior. It discusses creating new ore blocks with specific mining times and experience drop rates, and how to duplicate and modify existing block settings for different types of ores. The tutorial also covers how to add these ore blocks to the creative mode tab and to the appropriate mining tags, such as 'needs_diamond_tool' for blocks that require a diamond pickaxe to drop items. The paragraph concludes with a demonstration of the in-game functionality, showing the correct dropping of items and experience when the custom blocks are mined with the appropriate tools.

15:04

🎮 Conclusion and Preview of Future Tutorials

The final paragraph wraps up the tutorial by summarizing the achievements, which include successfully setting up custom loot tables and tags for mining custom blocks in Minecraft. It highlights the successful in-game testing of the ore blocks, which now drop raw materials and experience as intended. The paragraph ends with a teaser for the next tutorial, which promises to cover advanced item creation, suggesting that the series will continue to explore more complex aspects of Minecraft modding.

Keywords

💡Loot tables

Loot tables in Minecraft determine what items are dropped when a player interacts with blocks, mobs, or containers. In the video, loot tables are explained as a way to specify what should be dropped when a custom block, such as a Ruby block, is destroyed. The tutorial covers how to set up loot tables for both custom blocks and ores.

💡Custom blocks

Custom blocks are unique blocks added through Minecraft modding. The video explains how to add custom blocks like 'Ruby block' and 'Raw Ruby block' into a mod, specifying their loot tables and behavior when destroyed. These blocks require specific conditions like the correct tools to drop items.

💡Conditions

Conditions in Minecraft modding define specific criteria that must be met for something to happen, such as blocks dropping items. In the video, the condition 'Minecraft:survives_explosion' is used to make sure that the Ruby block can drop its item even when destroyed by an explosion. Conditions help modders control how and when items are dropped from blocks.

💡Tags

Tags are used in Minecraft to group together blocks, items, or other entities that share similar behaviors. In this tutorial, tags are applied to custom blocks to determine what tools are needed to mine them (e.g., pickaxe or axe) and the tier of the tool required (stone, iron, etc.). Tags ensure proper mining behavior for different blocks.

💡Fabric modding

Fabric is a modding framework for Minecraft that allows developers to create and implement mods efficiently. In the video, Fabric is used to create custom blocks and loot tables, with special directories and files such as 'needs_tool_level' being placed in Fabric's data folder to control item drops and mining behavior.

💡Json files

Json files are data files used in Minecraft modding to define various settings such as loot tables, tags, and block properties. The video shows how Json files are used to configure blocks like Ruby ore and Raw Ruby block, specifying their loot tables and conditions for dropping items when mined.

💡Minable tag

The 'minable' tag in Minecraft specifies which tools can be used to mine specific blocks. In the video, this tag is added to the custom Ruby blocks to indicate that they must be mined with a pickaxe. This ensures that blocks drop the correct items only when mined with the right tool, preventing drops if mined with inappropriate tools like axes.

💡Experience dropping blocks

Experience dropping blocks in Minecraft release experience points when mined. In the video, the Ruby ore is defined as an 'experience dropping block,' meaning players will receive experience points when mining it. The video demonstrates how to customize the amount of experience that can drop from these blocks, using values similar to those of vanilla ores like Lapis or Diamond.

💡Ore blocks

Ore blocks are special types of blocks that contain valuable materials, such as Ruby ore in this modding tutorial. The video walks through the process of creating different types of Ruby ore blocks, including Deep Slate Ruby ore and Nether Ruby ore, and how to assign them loot tables and mining conditions.

💡Tool level

Tool level determines what tier of tool (e.g., stone, iron, diamond) is required to mine a block. In the video, tool levels are set for custom blocks like Ruby ore, with the 'needs_tool_level' tag ensuring that only certain pickaxes can mine them. This level dictates whether the block can be mined and if it will drop items.

let's add drops to our blocks with loot

tables

Minecraft modding courses with close to

100 topics ranging from Custom tools and

armor to custom block entities all the

way to custom mobs Linked In the

description below oh really fences back

until everyone's more and in this

tutorial we're gonna be adding a custom

loot tables to Minecraft and our mod and

loot tables basically determine what is

going to be dropped for example when you

destroy a block or they can also

determine other things like what types

of items are going to be inside of luge

chests right in certain structures what

different entities drop all of those

things governed by loot tables and in

this tutorial we're first of all going

to add the loot table to our custom

blocks and then there's a second part of

this tutorial where we'll actually have

to also add our blocks to a certain tag

in order for the blocks to actually drop

something but one step after the other

first of all you need tutorial mode data

folder we can right click new directory

called loot underscore tables make sure

that this is written correctly loot

underscore tables exactly like this

nothing else and inside of that folder

another folder called blocks please make

sure that this is done correctly I've

seen Every Which Way that this has been

written wrong it has to be data folder

tutorial mode or your mod ID load

underscore tables and then blocks and

then here in this case the name of the

Json file actually once again has to

match the name given right here in the

modblocks class so Ruby underscore block

and raw Ruby underscore block let's

start with the Ruby blocks let's create

a new file over here Ruby underscore

block dot Json here in this case there

you go and once again I will just type

out the contents here and then we'll go

through and see what all of this

craziness is so first of all this is of

course once again a type and the type

here is a Minecraft colon block because

this is a block loot table we then

Define some pools so pools is once again

a list here in this case or an array and

in this case we will only Define one

pool and the pool has zero bonus rules

bonus rolls of zero and then conditions

are going to be a standard condition and

that is going to be condition Minecraft

colon survives

underscore explosion after the list of

the conditions you then Define entries

in this case we have an entries list

over here we're going to have a one

entry that is going to be of type

Minecraft

colon item and the name of this item is

going to be tutorial mod colon Ruby

underscore block

and this whole thing is done with the

number of rolls of one awesome the first

question you might ask is what the frick

is this condition well the condition

basically just means that the Ruby block

will also fall when an explosion

destroys this block should be fairly

self-explanatory and what is going to

drop is exactly what we Define in this

entry over here and that's the Ruby

block I highly recommend checking out

either the loot table fandom Wiki

article over here or the loot table

generator for misode which is going to

be very useful indeed as long as we

don't have the data generation that's

going to make the loot tables about a

million times easier those basically

tell you a bunch of stuff that the loot

tables can contain and what everything

means I will link those in the

description below but just like the

recipes of course give access to all of

the loot tables in the external

libraries which is going to go down all

the way here to the Minecraft merge

project and we will look in the data

folder Minecraft loot tables we are

going to go into the blocks folder and

here we go every single loot table for

every single block that exists in

Minecraft it couldn't be easier how to

Planck's drop well I mean they literally

drop exactly the same way as the Ruby

over here they just drop themselves

right so most of this stuff is going to

look very similar the only things that

might look a little bit different are

ore blocks let's cover first of all the

raw Ruby block for this we're just going

to drag the same adjacent file into the

same folder while holding Ctrl and we're

just going to rename this to Raw Ruby

block and similar here this is just the

raw Ruby block as of right now your

blocks will still not drop something

because they have the block setting

inherited from the iron block that is

called requires tool and if requires

tool is called on your particular block

that means that it can only be mined or

it only will drop something if the

correct tool is going to be used for

this and for that you need to add this

to a tag now in the highest level

overview tags are simply collections of

blocks items or sometimes some other

things that have a similar purpose and

in our case we need to add our blocks to

a minable tag that's going to determine

whether or not it can be mined with a

pickaxe an ax a shovel or a hoe and we

can also add it to a needs extrude tag

which basically determines whether or

not it has to have a certain tier of

tool to be minable this happens in the

data folder again but this time instead

of the Minecraft directory inside they

will make a new directory called Tags

and inside of there once again we want

to make a new directory called blocks

and lastly we also want to make another

new directory called minable now in the

mindable folder we'll create four Json

files this is going to be the ax.json

I'll already put the Json file contents

in here so you can see a Json file is

very very straightforward it's just the

curly brackets then a replace faults and

then a list of values this time it's

empty because I just wanted to copy over

this Json file for all the other tags

that we need because it's quite a few

actually so when you have this you can

of course also take a look at all the

Json files in the description below in

the GitHub repository and what you can

do is we can just drag this into the

same folder and we can call this the

pickaxe.json and then we can drag this

into the same folder again once again

while holding Ctrl we can call this the

shovel and then lastly the whole and

then there's extremely important the

other ones traded in the locks folder

not the minable folder so we drag this

into the blocks folder this time I'm

going to call this the needs underscore

iron underscore tool and then once again

dragging this into the blocks folder

needs Diamond Tool and this actually

also needs

Stone tool so those are the different

levels if you want to require nether

right or higher what you have to do is

you have to do this in another folder is

a little annoying but it is what it is

so in the data folder right click new

directory called Fabric and then inside

of there we want to make a new directory

called Tags and then another new

directory called the blocks and then

inside there we can make the following

Json file and that's the needs

underscore tool underscore level

underscore 4. and the needs underscore

tool underscore level underscore for

Json file under the fabric folder here

that's quite important that one

basically allows you to make your block

only minable with netherrite let's start

with the pickaxe Json because in our

case well obviously the Ruby block in

the Raw Ruby block should only be

minable with a pickaxe here so we're

going to add those tutorial mod colon

Ruby underscore block and then similarly

the second one is just going to be the

raw Ruby block there we go in this case

if we leave it like this now our Ruby

block and our raw Ruby block can be

mined with any pickaxe including it will

wooden pickaxe if we then say you know

what I actually want my raw Ruby block

to only be mineable with an iron pickaxe

then we just add it right here and then

for example maybe we say you know what

and then I only want my Ruby block to be

minable with a stone pickaxe let's say

there we go now this is going to be done

do keep in mind that when you have the

need Stone tool for example your Ruby

block now would also be minable with

iron diamond and netherride and anything

above it so it always is basically this

particular two level or higher I do not

believe there is an easy way to make

this function a different way just keep

that in mind and with this way the Ruby

Rock and the raw Ruby block given the

correct tools will now drop something

and we'll actually take a look at this

and then we'll take a look at the ores

as well but first of all let's go into

the game and see our blocks drop

something all right fine stuff in

Minecraft and I've prepared all of our

blocks over here and I've also prepared

well some of my pickaxes so in this case

neither the Ruby block nor the raw Ruby

block should be mindable with a well

normal pickaxe here in this case a

wooden pickaxe and you can see it

already takes a really long time and

there's a very good indication that this

is probably not going to work but we'll

just let this run through and there we

go nothing dropped if I use a stone

pickaxe however let's see this is a

little bit faster and there we go a Ruby

block drop awesome now the raw Ruby we

defined only being able to be mindable

with a iron pickaxe so if we use Stone

right here it is okay in terms of speed

but you will see it is not going to drop

anything

there we go got nothing however with an

iron pickaxe it is going to drop awesome

and of course also with an ax this does

not work you can see it is already

taking way too long like you would

probably never do this similar with this

one right here even with the never light

ax doesn't work however higher tiers

such as Diamond that works totally fine

and then similar netherride also works

totally fine for all of our blocks here

as I've said the tools here that you

define is always the one that it needs

or higher than that and now let's also

take a look at some ore so for this I

will be copying over four different

blocks that we're going to need and what

I mean by copying over is I'm going to

create one of them and then the other

three I'm just going to well basically

copy over all of the code is of course

available to you in the description

below so no worries at all so you should

be totally fine all right so to add ore

we're just going to do a public static

final and there's going to be a block

once again this is going to be the Ruby

underscore or this will be equal to the

register block method I'm going to call

this the Ruby underscore or right here

now instead of a new block this is going

to be a new experience dropping block

here in this case and the first

parameter of which is just going to be

fabric block settings dot copy of and

we're going to copy block start Stone we

can then also Define the strength over

here this is just going to be how long

it's going to take to actually break

this particular Block in this case so

maybe we want this to be you know taking

a little bit longer than stone stone for

reference over here we can take a look

at this has a strength of 1.5 so maybe

we say that this has a strength of two

and then after the first closing

parenthesis after the strength over here

we then also wanted to add a uniformind

provider dot create and this is going to

determine how much experience this block

will drop when you actually destroy it

so for example we're just going to

choose between two and five over here

ended with a semicolon here at the end

and then your Ruby or has been created

to double check the vanilla values of

the ore blocks just middle Mouse one

click on the experience dropping block

over here middle Mouse one click here

again and in the blocks class you will

be able to find lapis for example or

Diamond let's just take a look at lapis

at the very end over here we'll be able

to find that lapis drops between 2 and 5

as well and we can take a look at the

other ore blocks as well so for example

emerald ore that's going to be in 628 in

see that one drops between three and

seven the numbers those are always

things that you have to take a look at

yourself and basically change in

whatever which way you like to balance

your mod properly but that's going to be

a good idea here for the moment I don't

want to end with Ruby or no no I want to

duplicate this four times so just select

it press Ctrl D to duplicate and I also

want the Deep slate Ruby ore of course

very important that we change the name

right here if you do not change the name

inside of the register block method that

you give it then we will run into an

error and the actual game will not start

here we of course want to copy the

blocks.deep slate in order to get the

Deep slight sounds

and the strength might be 4 because it's

a little bit hard we are also going to

get the nether Ruby ore this is going to

be the nether Ruby ore there we go

and this is of course going to copy well

Netherrack and maybe this is actually a

little bit of a lesser strength because

Netherrack is not really that strong

and then lastly we have end we have end

stone ruby ore and of course changing

the name here as well and stone ruby ore

and this is going to be copying the end

stone block

and here once again maybe with a little

bit more strength because why not you

can of course also play around with the

in providers over here so for example oh

the end or that's going to give you way

more experience because the wall is way

crazier and way more harder way harder

to get to the end to actually mine this

ore so there you go that could be one of

the reasons why you would do that there

we go I've added all of the oars to the

creative mode tab this really shouldn't

be anything crazy let's just add the

translation all of this should be fairly

self-explanatory at the end of the day

it literally is just changing the name

right here and then changing whatever

the translation is it should be pretty

trivial at this point then of course now

to have the blocks properly added yes we

do need to add all of the Json files

that is a little bit of annoying thing

but like I said just give it a few more

tutorials and then we're going to add

this in record speed yes in this case we

do need to copy them over now I'm going

to cheat and I have already prepared

them and I'm just going to copy them

over like this but you can see the

contents of them are literally exactly

the same compared to the Ruby block and

the raw Ruby block so really it

shouldn't be any issue at all and of

course the contents you can always take

a look at those in the GitHub repository

as well alright the textures here as

well and those are of course always

going to be available to you for

download in the description below and

now to the interesting thing and that is

adding all of them to the tags so of

course we can just add all of them to

the pickaxe tag because all of those

four ores would be minable with the

pickaxe so there we go basically just

add it to the pickaxe Json file and now

let's just play around with this a

little bit so let's for example say that

the End Stone can only be mined with

netherrite here so we're going to add

this to the neat underscore tool

underscore level underscore for Json

file in the data fabric tags blocks

folder over here very important and we

will be able to see that we can only

ever mine this with a netherride pickaxe

or higher if we add custom levels and

see that in a future tutorial as well

and then let's say for example that the

Deep State can only be mined with

diamond here for example and now while

they can be mined well they won't drop

anything yet because we still haven't

added the loot tables so you can see

there is a little bit of a process over

here but like I said once we go through

this once you understand you have to

understand sort of what the process is

right what are loot tables what are they

good for what are tags what are they

good for what do they do especially the

minable and the he needs you know X tool

tag after you've understood what all of

those do then we're going to be able to

make them way easier with datagen but

for the time being it's a little bit

more of an involved process and for the

ore blocks what I recommend is you go to

the external libraries once again down

to the emerge project over here to data

loot tables blocks and you just take a

look at for example the copper ore one

now this one will actually shock you I'm

gonna open this and you're gonna be like

oh my Lord what is all of this craziness

absolutely not to worry we're just going

to copy this over so select it press

Ctrl C to copy it and then Ctrl V

pasting it into the correct folder over

here I'm going to rename this to the

Ruby or and then we just need to make

sure that we change everything in the

correct places so for example here where

it drops the copper ore when we use silk

touch we want it to drop tutorial mode

colon Ruby underscore or and then down

here instead of raw copper we wanted to

drop raw Ruby of course making sure we

also change Minecraft over here to

tutorial mode this is extremely

important and then down here we're just

going to call this the tutorial mode

blocks Ruby orb awesome and now we can

just duplicate this a couple of times

this is going to be the Deep slate

underscore Ruby ore and then there's

going to be the Deep slate Ruby ore and

for the raw Ruby that's still going to

drop and then here you can of course see

this is a uniform distribution so it

will drop between two and five you can

of course change this you know so for

example you might say oh for the website

it should drop between three and six

something like that you can always of

course change the numbers highly

recommended to try this out and and just

play around with this a little bit

alright and just for the sake of

argument I've also added the Nether and

the end stone ruby or block loot tables

once again you can take a look at those

in the GitHub repository and now we can

go into the game we can see our ore and

we can see them drop something when we

mine them alright here we are in

Minecraft and let's just try and mine

our ores and you can see there we go so

that works no worries at all diamond

pickaxe or the Deep slight also works

for the nether also works but here it

should not work because the N Stone

should only be minable exactly with

netherrite and let's take a look and

then we go so absolutely Works no

worries at all absolutely amazing we got

our ore drops they drop our raw Ruby

they drop experience absolutely freaking

fantastic right that's gonna be it for

this tutorial right here next time we're

gonna do an advanced item very cool

stuff take a look at it here and I hope

to see you there so yeah
