i need to make a datapack that generate an structure at 00 coordinates and do not spawn anywhere else
#structure that spawns only once and in specfic coordinates
lethal arrow
supple kettle
use the /place structure command
maiden lodgeBOT
supple kettle
you might want to use /execute over to make it spawn on land
lethal arrow
sorry but i do not understand anything about datapacks is there is a tutorial for the basic?
supple kettle
supple kettle
yeah, the naturally spawning chest items are defined in a loot table. You just remove the items from the default loot table for the chest
supple kettle
then the mod overrides the loot table, so you’ll have to make sure the datapack is on top of the datapack list when you install it
lethal arrow
when i extracted the jar files i found the loot tables should i just make the item weight zero?
and then put the new loot tables in a datapack?
supple kettle
that should work, and yeah just put them in a new datapack
supple kettle
change the set_count Count field to 0. That would probably be the easiest way to do it.
lethal arrow
ok thank you
lethal arrow
bro i changed it now it works well now i want to make a certain items drop from certain mobs
how to do that
open veldt
u can use a loot table generator
its so much easier
like this one: https://misode.github.io/loot-table/
open veldt
should work fine
so how datapack work is they override or add content to mc in there format
u wanna override a loot table of a mob
so u have to follow mc format (data/minecraft/loot_tables/...)
and replace the file there
in ur datapack
lethal arrow
can i call u?>
open veldt
no
open veldt
yes
open veldt
lethal arrow
bro i made a loot table how to make mob get that loot table?
@supple kettle bro that syntax is wierd where should i write it and what does all the brackets mean
and the place command doe not work
supple kettle
<@543741360478355456> bro that syntax is wierd where should i write it and what ...
(replying to ^^)
lethal arrow
(replying to ^^)
so what is the answer to my question>
supple kettle
so what is the answer to my question>
you said that the syntax is weird and what does all the brackets mean so i sent you a guide to JSON syntax
lethal arrow
uhhh
supple kettle
like this one: https://misode.github.io/loot-table/
anyway, did you see this?
lethal arrow
yes i mad a loot
supple kettle
it generates the json for you
supple kettle
which mob?
lethal arrow
modded one
bro what i meant it looke wierd is what should i write in these brackets
supple kettle
okay, to repeat what I just said, if you don't know how to write JSON, then use the loot table generator: https://misode.github.io/loot-table/
lethal arrow
i have a structure i want to generate the first time a player joins the world in a specfic coordinates and it should be unbreackable
how the llot tables help me
supple kettle
i don't know? you were the one who asked how to use the loot tables
lethal arrow
ahhh sorry i forgot i asked 2 questions
supple kettle
lol it's fine, just gets a bit confusing
supple kettle
so is that saved in data/<namespace>/structures/whatever.nbt?
lethal arrow
no its is in saves\New World (3)\generated\minecraft\structures
supple kettle
well you first have to put it in the datapack so that the datapack can access it
supple kettle
so is that saved in `data/<namespace>/structures/whatever.nbt`?
in here ^^^
lethal arrow
ok let me doi rq
data\strater_castle\data\starter_castle\structures
does this look good
supple kettle
yeah
then after this, you gotta add two more files
one sec
what's the structure NBT file called?
lethal arrow
castlestart
supple kettle
data\strater_castle\data\starter_castle\structures
btw you misspelled starter_castle (after data/)
supple kettle
ok so then in data/starter_castle/worldgen/structure/castlestart.json, put this:json { "type": "minecraft:jigsaw", "biomes": "#minecraft:has_structure/mineshaft", "step": "surface_structures", "spawn_overrides": {}, "terrain_adaptation": "beard_thin", "start_pool": "starter_castle:castlestart", "size": 1, "start_height": { "absolute": 0 }, "project_start_to_heightmap": "WORLD_SURFACE_WG", "max_distance_from_center": 80, "use_expansion_hack": false }
and also in data/starter_castle/worldgen/template_pool/castlestart.json, put this:json { "name": "starter_castle:castlestart", "fallback": "minecraft:empty", "elements": [ { "weight": 1, "element": { "element_type": "minecraft:single_pool_element", "location": "starter_castle:castlestart", "projection": "rigid", "processors": "minecraft:empty" } } ] }
lethal arrow
so thsi will spawn the structure at what coordinates?
supple kettle
nowhere yet. but it will let you use /place structure starter_castle:castlestart
lethal arrow
ok just a question can i make the staructure unbreackable?
supple kettle
not easily
lethal arrow
ok can i make when you enter the structure you get mining fatigue>
supple kettle
in theory you can put a command block in the structure which gives nearby players mining fatigue
supple kettle
thank u :>
supple kettle
close enough, just find a radius which is big enough so that people nearby get mining fatigue: effect give @a[distance=..RADIUS] mining_fatigue 1 20 true (replace RADIUS with a number)
supple kettle
did you /reload and stuff
lethal arrow
yes i logged out and in
supple kettle
but did you run /reload in chat?
lethal arrow
yes
supple kettle
oki good
can you zip and send your datapack here so i can make sure it's all in the right place
supple kettle
you used world_gen instead of worldgen in data/starter_castle/
other than that, it all looks okay, but that's whats causing your issue
supple kettle
what minecraft version are you using?
lethal arrow
1.18.2
supple kettle
that may be a problem considering i'm using the 1.19+ version of structures
it shouldn't be too hard to change it
lethal arrow
the pack format should be 9 right?
supple kettle
that doesn't matter for now
maiden lodgeBOT
supple kettle
but yes
lethal arrow
it shouldn't be too hard to change it
but i am brainddead in commands
supple kettle
but i am brainddead in commands
nah don't worry. Just rename the folder structure (in worldgen) to configured_structure_feature
lethal arrow
ok did it
supple kettle
and change configured_structure_feature/castlestart.json to this:json { "type": "minecraft:village", "config": { "start_pool": "starter_castle:castlestart", "size": 1 }, "biomes": "#minecraft:has_structure/mineshaft", "adapt_noise": true, "spawn_overrides": {} }
lethal arrow
ok did it
supple kettle
then /reload, exit world then open it again, and try again
supple kettle
where's data/ and pack.mcmeta?
supple kettle
okay TIL openloader is a thing
supple kettle
today I learnt
lethal arrow
finally i gave you something in return
supple kettle
when you join the world, is there a warning like "experimental features" or something
lethal arrow
but when i type datapack list the datapack is there
supple kettle
ok i'm going to load this datapack in my game
lethal arrow
ok sure thing
supple kettle
but when i type datapack list the datapack is there
what place command are you using btw
lethal arrow
i mean when i type /datapack list
supple kettle
no i know
lethal arrow
:::::::::::::::::(
supple kettle
as was most things that would make this easier
but no worries
we just do a bit more work
lethal arrow
man you make me feel like am your ur son
supple kettle
lol
lethal arrow
you always know what to do
supple kettle
ok so basically what you have to do is place a structure block at 0,0 and then power the structure block. there are two problems with this though:
- you don't know what Y-level the surface is
- you don't know if 0,0 is going to be loaded/within simulation distance when you want to place the structure
and 3. we don't know whether 0,0 is on land, it could be in the ocean, or worse in a void world
to be fair, 2 and 3 are both still issues in 1.19+ but they're easier to solve
time to problem solve :)
lethal arrow
bro u sure that is free??
no pay?
cuz thank y
u
i will use a mod that will force the spawn pont to chosen cordinates
supple kettle
- you can start at y=256 and fire an arrow downwards very fast to get the surface level
- this isn't actually a big issue - 0,0 is usually the spawn point and therefore is usually loaded (spawn chunks are loaded). but even if they aren't, we can still place the block and the structure will be placed the next time the player loads 0,0
- this is still quite a big issue and I'm not sure how to solve it
anyway I kinda have to go sooooo <@&935561184806060073>: tldr this person wants to place a starter castle structure at world spawn in 1.18.2
lethal arrow
for the context the y coordintes of the structure will be also spesfic so that will not be an issue
it will not be a problem if i spawend a little bit higher or lower than the surface
wild patrol
you can setblock a structure block and activate it with a Redstone block.
lethal arrow
the structure should spawn automatically with no interfernce from the player
wild patrol
It does, if you set the Redstone block with a command too.
wild patrol
I'll shower and then I can explain you how to do it.
lethal arrow
Bro did u finish ur shower?
brisk wind
wild patrol
sry for the delay, something came in between.
do you already have the structure saved as a file?
lethal arrow
Yes i have
wild patrol
use this command setblock ~ ~ ~ structure_block[mode=load]{name:"<Structurefile Path>",rotation:"NONE",mirror:"NONE",mode:"LOAD"} to place the structure block.
After that command use setblock to place a redstone block one block above the structure block.
If you want it to spawn instantly when entering the world, you could use a tick advancement to trigger the function, that places the blocks. important is, to limit the function to only execute once.
wild patrol
functions go in data/<namespace>/functions/... and advancements go in data/<namespace>/advancements/...
lethal arrow
Ok and the structure that this function will use?
wild patrol
data/<namespace>/structures/...
lethal arrow
And infront of the setblock should be the coordinates that the block should spawn in right?
wild patrol
And infront of the setblock should be the coordinates that the block should spaw...
replace the ~ ~ ~ with your coordinates
wild patrol
And how to make it only once
btw, forget the advancement
To make it trigger only once, you can do this for example:
load.mcfunction
scoreboard objective add internal dummy
execute unless score startStructure internal matches 1 run function <namespace>:place
place.mcfunction
setblock 0 80 0 structure_block[mode=load]{name:"<Structurefile Path>",rotation:"NONE",mirror:"NONE",mode:"LOAD"}
setblock 0 81 0 redstone_block
scoreboard players set startStructure internal 1
So i just copy these files and put them in their places and that is it
Or should i do something more?
Other than changing the coordinates
wild patrol
replace <Structurefile Path> in the setblock command with your structure file path
that should do the trick
wild patrol
Which will be in the data pack
which what?
wild patrol
the namespace
if you put the file in the structures folder without any subfolders, it would just be namspcace:filename
lethal arrow
So namespace/structure
lethal arrow
Uh ok i can put where i want in the namespace
wild patrol
namespaces are always seperated by a : from the rest
lethal arrow
but with a :
Instead of the slash
wild patrol
Instead of the slash
yes
lethal arrow
Let me try this rq
wild patrol
Uh ok i can put where i want in the namespace
<namespace>:structures/<filename>
lethal arrow
also the funcion json files can be any naem right
wild patrol
they can be any name but they are not .json files. The have .mcfunction.
lethal arrow
also i should not include.nbt in the structre name right
wild patrol
those are .json files
lethal arrow
i mean the structre is in.nbt
lethal arrow
what do u mean
wild patrol
you were right they are .nbt files, and you don't include them in the setblock command.
wild patrol
looks ok but there were a few things not right. I fixed them rq. I also forgot to mention that you need to list the load.mcfunction file as a load function, I added that too.
Another thing, you can't zip the folder with the files inside. You need to zip the files inside the folder.
wild patrol
wtf is with your structure?
My Minecraft crashed because of out of memory error. I have 55GB Ram for mc
supple kettle
lmao what
lethal arrow
it is a bit large
supple kettle
“A bit large”
wild patrol
max is 48x48x48
lethal arrow
i use a mod called structure expansion to increase that
i found u forgot to change the structure path in the place function
lethal arrow
huh?
wild patrol
no error
lethal arrow
but the structure is not there
supple kettle
it is otherwise it wouldn’t be underlined
wild patrol
but the structure is not there
lethal arrow
openloader\data\strater_castle\data\starter_castle\structures
this is where the structure is now
supple kettle
yeah, that’s correct
lethal arrow
in ur datapack that u sent
supple kettle
yep
so the namespace (before the colon) is starter_castle
then the structure is castlestart
so it’s starter_castle:castlestart
you ignore the structures folder because the game is looking for a structure anyway
it looks in that folder anyway
lethal arrow
no
supple kettle
it’s just how namespaces in Minecraft work
wild patrol
Does the mod change more than just the structure block size?
supple kettle
i changed it now it works
seems unlikely, because that’s not how Minecraft works at all
lethal arrow
Does the mod change more than just the structure block size?
no
but the structure contains blocks from various mods
wild patrol
that's why mc crashes and vsc doesn't render
supple kettle
so if the structure block now works, is this question solved?
lethal arrow
Just give half an hour to ensure every inch of it works
lethal arrow
I tweaked some things in the structure i replaced them but it spawns the old structure still
Not asking for anything just want u to not not marked it as solved yet
wild patrol
if your question is answered in the future, you can resolve it too with /resolve
wild patrol
then the delay is too short.
Summon a falling redstone block two blocks above instead. This should give it enough time.
or does the structure also not spawn if you do it manually?
lethal arrow
no it does no genrate the structure even if i try manually
because i do not have the genrated folder
wild patrol
then the structure is broken
lethal arrow
i wrote the structure path starter_castle:data:starter_castle:structures:castlestart
in what way?
wild patrol
i wrote the structure path starter_castle:data:starter_castle:structures:castles...
try only this starter_castle:structures
lethal arrow
in the datapack or manually
wild patrol
manually first, to check if it works
lethal arrow
manually says is not available
wild patrol
idk maybe the mods are broken or they break data packs.
lethal arrow
but when i copy and paste the genrated folder the structure genrate normally
lethal arrow
even now when i change the structure path to the one u wrote before it still spawns the blocks but not the structures?
this is the direct folder after openloader
I never thought it will be this hrd
Hard
supple kettle
manually says is not available
does starter_castle:castlestart work?
supple kettle
but why
open veldt
idk im not op
lethal arrow
~~but why~~
Because I thought you got sick of me so i wanted not to push firther
Further
lethal arrow
does starter_castle:castlestart work?
No i tried every way to right write the comman but it says not available unless i copy the genrated folder from my main world
lethal arrow
Ok i will try and tell
maiden lodgeBOT
lethal arrow
now it works thank u,but also lets make sure so not close this thread plz
lethal arrow
it works fine but there is a silly issue when the structure genrates it might destroy things like dungeon chest and so on so i want the datapacks to clear all drooped items once after the structure is genrated
open veldt
you can do /kill @e[type=item]
lethal arrow
bro where should i put that in the datapack
should i write it in the place or load?
open veldt
after u spawn the structure
lethal arrow
like in the chat?
open veldt
no in place.mcfunction
lethal arrow
bro i copy and pasted it in place.mcfunction but it is red
open veldt
remove the / '~'
lethal arrow
ok another thing if u may i want to make the command tellraw activate the first time someone joins the world and not any more
open veldt
use a scoreboard
lethal arrow
and that would translate to what code?
open veldt
#############################################################################
################ load.mcfunction #############################
#############################################################################
scoreboard objectives add joined dummy
execute if score @s joined matches 0 run function <namespace>:place
#############################################################################
############### place.mcfunction ##############################
#############################################################################
scoreboard players set @s joined 1
that name space whouild be the text?
or that would be /tellraw @p "text" in load.mcfunction plus all the other things?
supple kettle
that name space whouild be the text?
no, the namespace would be starter_castle. basically, the folder after data
lethal arrow
but where should i write the command
supple kettle
if you want it to work the first time someone joins then it's a bit different
unless im confused
lethal arrow
I want a messege to be in the chat the first time someone joins the world
supple kettle
is load.mcfunction the one listed inside data/minecraft/tags/functions/load.json
lethal arrow
yes but what is the message that will apear?
supple kettle
the easiest way for you to send a player when they join is to create an advancement which has a tick criteria, and then the reward of the advancement would be a function which sends the message to @s
lethal arrow
but why not use the tellraw ?
supple kettle
no it does use the tellraw
the player will unlock the advancement just by joining the world. when the player unlocks the advancement, it runs a function. in the function is the tellraw command
lethal arrow
but wouldnt taht also send the player a msg that says he completed etc advancment>
supple kettle
no because you can turn that off
supple kettle
if you leave out the display section of the advancement, it won't show anyway
its less of a "turn it off" but more "its turned on for every advancement"
i suppose you could say its off by default
lethal arrow
okay
supple kettle
this is the advancement, it should go in data/starter_castle/advancements/join.json: ```json
{
"criteria": {
"requirement": {
"trigger": "minecraft:tick"
}
},
"rewards": {
"function": "starter_castle:on_join"
}
}
then you need to make a function `data/starter_castle/functions/on_join.mcfunction`:```d
tellraw @s "hi"```o f wrong one
maiden lodgeBOT
supple kettle
you'll only need to pay attention to . ├── pack.mcmeta └── data └── starter_castle ├── advancements ├── functions └── structures
lethal arrow
does this look right?
supple kettle
yeah
lethal arrow
@supple kettle
bro does this look right?
the only thing i did was changing the msg from hi to what it is now
but the jigsaw does not eaven spawn nor the redstone
supple kettle
but the jigsaw does not eaven spawn nor the redstone
if it doesn’t spawn then it’s probably not right
lethal arrow
I tried in another modpack with less mods and it worked
Could some mod mess with this?
cunning falcon
yes that can definitely be the case
mods can change every part of the game and most mod authors don't plan for data pack compatibility
lethal arrow
Ok thank i will see what i can do
lethal arrow
uh guys
i need help
the datapack you made is good and all but there is a slight problem
it does not work when i have other datapacks
or no
bro the datapack sometimes work and sometimes not
the text always apear but the structure does not always spawn
@supple kettle
particulery it spawns every other world
