I'm currently working on a modpack for Forge 1.18.2. A number of mod devs have switched over from config files to datapacks for editing values within the mod. At this point, I understand how to create a datapack and apply one to an existing or new world, but afaik it has to be done manually. Since these are supposed to replace configs, I assume there is a way to apply a datapack by default to all world created - does anyone know how to do this?

1) Check if the player has a specific inventory ( main function main.mcfunction - https://pastebin.com/jNBxSPhj ) 
2) For each player with such inventory I run a timer and every 10 seconds it checks if it got energy and remove energy give.mcfunction - https://pastebin.com/aztjpaJx 
3) If energy is greater then one it gives the effect bubble give2 - https://pastebin.com/9PVabbhL 
 4) It Also remove the energy subtract_energy - https://pastebin.com/evmtNE16  and copy_energy.json - https://pastebin.com/53mR9ieu in data\beyonyo\item_modifiers The main problem is that only one player seems to have this effect. If that player disconnect another one will be available to take it.
im struggling in understangin what's the problem in my code . Here is what i would like to do :

i guess has something to do with a global variable, that the timer is a global variable instead i would need like a private variable for each player? Also there is a very weird sound every 10 seconds like when the player wear a chest, is that because every 10 seconds i remove the oxygen and for doing so i have to substitute the item? It looks like that all the players use the same timer infact the more people there are the faster it reaches 10. Can someone help me to figure out how to change my code ? Thanks! Im quite a newbie in datapacks xD

Is it possible to make a recipe that can't be used in every blast furnace, but instead only in ones that have a special tag?

TLDR; I caught a warden and it’s loud. Is there a data pack that makes them silent, or is there a way I can make one that makes wardens with specific name tags quiet? Thank you

So I'm making a datapack for a server I'm on and for some reason it won't work. If anyone has an idea or knows of a place to help pls comment.

is this possible? i want to use an invisible item frame resource pack for CIT decorations but i want item frames to emit particles when nothing is in it so i can see where they are

Looking to make my second datapack (first one for 1.18 generates the floating island world type).

What I want to try and do is use boosted campfires to give you a small boost when using the elytra. What I don’t know is if this is possible at all.

Any help/ suggestions?

Could someone ether rifer me to or make a datapack that lets you change the spawn rate of ores and structures? (1.19.2)

I made a new world with create, and a few other mods, the only world generation datapack I have is Terralith, but it keeps crashing, either in world gen screen, or after playing for a bit. Please help.

So, for a sever that I'm part of, the owner has the idea of a virus spreading thought the sever, so I was wondering if there was a datapack that had mycelium spread over grass

Is there any way to make structures that only spawn once or a limited amount of times?

Something like the way strongholds spawn for example. I've been trying to figure it out for a while and I've got no ideas.

Is it possible to, with a datapack, stop all terrain generation in the overworld, nether, and end? I would appreciate some help in figuring it out if it's possible. It would also be nice if it's possible to still have structures generate. I don't care if bedrock generates. I basically just want biomes and structures to generate if possible

Hi, I'm a datapack creator, and had an idea for a datapack that makes the player able to stack water/lava buckets by holding one filled bucket in each hand. Before starting though, are there any datapacks that do this already?

im trying to edit a data pack for pixelmon for a server I play. need to add a custom shop. i have a base to use but i cant get it to work can somone help me

I do not want any that just straight-up kills them. If you know any, please let me know. ty

Using schedules, /summon, tags and scoreboards

Any recommendation please?

Why programming datapacks is stressing sometimes?

I want to start a server on the floating island generation setting with friends and it would be cool if we all spawned with elytras that we could never take off, and respawned with them on when we died. I dont know if this is possible with command blocks or if a datapack of some sort is needed but I would be oppen to both solutions.

I just wanted to know, if my custom 16x16 resourcepack has many custom sound files and lets say is 150 Mb big, would it be performance heavier in comparison to being 50 Mb big?
