you can use a # in front of text to make it a comment (meaning that it will not register toward code and crash your function)

winter agate Sep 23, 2025, 5:02 PM

#

where would i go about coding it myself im really bad

half gyro Sep 23, 2025, 5:05 PM

#

the best way to tackle a bigger problem is to split into smaller easier to fix problems. You can split your problem into 3 parts:

You'll need a way to check whether it is day or not. This can be easily done using a predicate. There is even a handy generator for it https://misode.github.io/predicate/
At night, you want to double the hearts, this can be done using an attribute modifier called max_health which can be applied using the command /attribute
When it's day you want to apply damage with a slight delay in between the hits, this can be done using a scoreboard timer to time when to apply damage and the /damage command to apply damage

#

If you need more help with the seporate parts feel free to ask. Since you've never made a datapack before I recommend first checking out our beginner's guide to get a little more familiar with datapacking

im on the website now

#

what code should i delete

#

im ngl ai made it 😭

half gyro Sep 23, 2025, 5:07 PM

#

winter agate im ngl ai made it 😭

then it'd be best to delete all of it.. It's really bad.. and I mean REALLY bad at making datapacks... xD

winter agate Sep 23, 2025, 5:07 PM

#

i fortunately know that now 😭

#

ive got it to raining : true

half gyro Sep 23, 2025, 5:08 PM

#

you'll get through it dw even if it feels really oververwelming

half gyro Sep 23, 2025, 5:09 PM

#

winter agate ive got it to raining : true

first start with the beginners guide so you get more comfortable with functions, json and the overall structure of datapacks

winter agate Sep 23, 2025, 5:10 PM

#

im watching a tut on predicates

half gyro Sep 23, 2025, 5:11 PM

#

hmm ok if it works for you then that's fine

winter agate Sep 23, 2025, 5:11 PM

#

i dont get what i add after raining : true

#

i would imagine its a string of commands to take damage

#

but im really bad at coding

half gyro Sep 23, 2025, 5:12 PM

#

winter agate i dont get what i add after raining : true

you don't want to do a weather check but instead do a time check

half gyro Sep 23, 2025, 5:14 PM

#

winter agate i would imagine its a string of commands to take damage

you won't code the commands directly inside the predicate, instead you'll have to make a ticking function (a function that runs every tick so 20 times a second) to check whether your predicate is true or not which would look like this execute if predicate <your_namespace>:<your_predicate> run ...

winter agate Sep 23, 2025, 5:16 PM

#

so i put the predicate in the tick function?

half gyro Sep 23, 2025, 5:17 PM

#

no you put the predicate in a .json file located at/data/<your_namespace>/predicate/

#

here is the overall folder structure of a datapakc

#

you only need the folders that will actually contain a file

#

the namespace is a folder with a custom lowercase name to differenciate datapacks from eachother

winter agate Sep 23, 2025, 5:19 PM

#

i downloaded a similar data pack

#

to compare

#

📎 dp-sun-burns-you-r1-17-1-1.zip

#

i still dont know what im looking at 😭

#

also it wont let me change my namespadew

#

namespace

#

it just loads then errors

half gyro Sep 23, 2025, 5:21 PM

#

for what minecraft version?

winter agate Sep 23, 2025, 5:21 PM

#

nvm ive done it

#

1.21.8

#

mine is

winter agate Sep 23, 2025, 5:22 PM

#

winter agate

1.20 i think

half gyro Sep 23, 2025, 5:22 PM

#

winter agate

it seems like this datapack is really outdated

winter agate Sep 23, 2025, 5:22 PM

#

i think it is

#

i think theres an easier way to go about it

#

from what i know i need something to tell the pack the time and one to execute the damage

half gyro Sep 23, 2025, 5:24 PM

#

nope this is the easiest way. The predicate is used for the datapack to tell the time and the ticking function is used to execute the damage

#

I'll make some steps for you to follow:
-# you'll have to wait a bit because I'm not the fastest typer xD

winter agate Sep 23, 2025, 5:25 PM

#

your very helpfu

half gyro Sep 23, 2025, 5:30 PM

#

Make a basic datapack structure with a valid pack.mcmeta (you can look if you've done it correctly by running /reload and then do /datapack list to see if your datapack is loaded correclty)

Let's start by making the ticking function
2. make the following folder structure: data/minecraft/tags/function/tick.json
3. in tick.json you'll add your function (which we haven't made yet) to the minecraft tick tree and tell minecraft to run it every tick. This can be done by adding your function to the values in the tag. It will look something like this

{
  "values": [
    "<your_namespace>:<your_function_name_it's_best_to_call_this_tick>"
  ]
}```
4. now create a file in ``data/<your_namespace>/function/<your_function_name_it's_best_to_call_this_tick>.mcfunction``
5. in that file you can temporarly put a ``/say Hello World!`` command to check if you did everything correctly
6. run ``/reload`` ingame and see if you get ``Hello World`` spammed in your chat

twin canyonBOT Sep 23, 2025, 5:35 PM

#

Now we can create the predicate
7. use the website I've sent earlier to generate a file that checks whether it is day
8. create a file in data/<your_namespace>/predicate/<your_predicate_name>.json and put the output of the website in there
9. now you can add your time check condition to your say command in your tick function to test your predicate this would look something like ```ansi
[35mexecute [34mif predicate [33m<your_namespace>:<your_predicate_name> [34mrun [35msay [0mhello_world

half gyro Sep 23, 2025, 5:36 PM

#

uuugh

#

the bot did weird

#

it sould look like this: execute if predicate <your_namespace>:<your_prediacte_name> run say Hello World

winter agate Sep 23, 2025, 5:39 PM

#

ive always used the basic tick and load code

half gyro Sep 23, 2025, 5:41 PM

#

ok so that already works?

winter agate Sep 23, 2025, 5:41 PM

#

theres nothing in them atm

#

i made the predicate file

#

#

do i just put the day time

half gyro Sep 23, 2025, 5:42 PM

#

ok nice put a say command in there to double check that it's working correcly please (this will save a lot of time)

winter agate Sep 23, 2025, 5:43 PM

#

i have the folder in my data pack folder but will it work if its not zipped?

half gyro Sep 23, 2025, 5:44 PM

#

winter agate

so what basically happens is that the time of the world gets divided by period and then the remainder is checked against values you want to have the period set to 24000 since that's the number of ticks in a minecraft day then you want to check if the value is between 0 and 12000 to check for the first half of the daylight cycle (which is when it's day)

winter agate Sep 23, 2025, 5:45 PM

#

okay period i understand not so much the value

#

your a phenomal teacher i have watched like 20 vids on data packs but learnt more from you then all of them 😭

winter agate Sep 23, 2025, 5:49 PM

#

twin canyon **Now we can create the predicate** 7. use the website I've sent earlier to gene...

"your predicate name" can that be anything i want

#

are you proud of me

#

IT WORKS

#

MY FIRST SUCCESFUL DATA PACK

same 😭

#

im so fricking happy tho

#

ive never been able to make a data pack work

#

now i have the freedom of learning stuff

#

look i did it myself

#

it took me 30 mins but

#

i did it myself

#

how do i get it to be a colour

for that you need text components and the tellraw command

winter agate Sep 23, 2025, 6:25 PM

#

this is as far as i got

#

idk what value does

#

if somoene can explain what value does i can try figure stuff out on my own

daring lintel Sep 23, 2025, 6:26 PM

#

winter agate idk what value does

There's a generator for it that shows a description on hover

#

winter agate Sep 23, 2025, 6:26 PM

#

yea but i dont understand what value does

#

and what i need it to be for my data pack

daring lintel Sep 23, 2025, 6:28 PM

#

Actually i dont understand it too

Sry

winter agate Sep 23, 2025, 6:28 PM

#

lmao dw

#

you helped me anyway with the other thing

daring lintel Sep 23, 2025, 6:31 PM

#

I looked at the wiki and i think i know now

#

  "condition": "minecraft:time_check",
  "value": {
    "min": 0,
    "max": 12000
  },
  "period": 24000
}

checks if its day

please just don't use AI... stats entity @e[tag=loopHandle] set QueryResult @s catchFire just doesn't / didn't exist at all
You won't learn anything if you're using AI to do everything for you. Instead use AI as a pocket teacher while not copying all the code... (tho AI can't even help with being a datapack teacher)
Using AI correctly sure is a skill but once you do you can learn to code A LOT faster
