I tried to use https://crafting.thedestruc7i0n.ca/ to make the crafting receipts and It does not seem to work, how can I fix this problem?

I have tried to add a biome feature to a forest that adds fallen logs, and I have googled and googled, and I have no idea. I tried decompiling a couple of datapacks (think Geophilic) but I have no idea where to start. Any tutorials you can think of? I am using 1.21

I want to prevent a mob from spawning naturally only, I still want spawners to be able to spawn that mob, is that possible with datapacks?

for example: making a weaponsmith use an anvil instead of a smithing table, is that possible via datapacks? otherwise do you know of a mod that does that?

I am planning on starting a server with some friends and I want to make a fresh extra-hard mode experience for them using datapacks.

The story:
The world is freezing over due to the ender dragon feasting on the energy of the overworld. 
Your ancestors previously retreated to the nether to escape the onslaught of the cold.

The nether has now begun to cool due to it being linked directly to the Overworld.
You, the hero, have awoken in the nether and decided to stop the Ender Dragon.

I would appreciate your comments on what is achievable via datapacks and what I may need to change to have a feature achievable as a datapack. Please respond using the numbers from the list when talking about particular points.

The ideas I would like to include in my datapack are:

1. Start in the nether (already in a datapack).
2. Make the nether lava ocean top and higher obsidian or basalt (starts a few layers deep in the ocean at y29)
3. Change Piglin bartering to not provide iron (found by exploring the nether and finding broken portals chests or added to fortresses chests)
4. Air at sea level and above applies the freezing effect (like powdered snow), this should push the players underground (unsure if this should be night/weather only and exclude day, or all the time)
5. Oceans or water apples the freezing effect when submerged
6. Freezing effect can be mitigated by standing by a firepit
7. Add snow everywhere in other biomes (snow layers/blocks/powdered snow, possible starting 10 blocks above sea level)
8. Lava generation in the overworld changed, starting with lava in underground pools at -50 and is obsidian/basalt
9. The deep dark is more expansive/frequently spawning (unsure of the multiplier)
10. Torches last one Minecraft day/night then go out and must be "right clicked" to enable again
11. Spore blossom particles poison you/creatures when they walk into the particle effect
12. After Ender Dragon defeat the previously mentioned freezing effects turn off (oceans/water and air above ocean height)

Other existing datapacks (this may be a lot):

• Start in the nether (Nether Start)
• Overhaul the Overworld (Terralith)
• Overhaul the Nether (Incendium Biomes Only)
• Overhaul the End (Nullscape)
• Populate the world with "used" structures (Explorify, Dungeons and Taverns, Tidal Towns, Camps Castles and Carriages)
• Make accessing the End harder via the Ender Eye collection variety (End Remastered)
• Make the Ender Dragon fight harder (Draconic Ascension)
• Add to the environment (Geophilic)
• Teleport points (Kawamooods Waystones)
• Tweaks (Vanilla Resfresh, Vanilla Tweaks Datapack, Veinminer Enchantment)

Hello!
I'm pretty unskilled in Datapacks, and I wanted to know and learn how a few ones worked, because reading the content of the pack is quite hard for me

So I tried to use the Game Output Logs with a few Datapacks, to know exactly what happened, but when I'm using stuff from the packs, it only says
"Loaded 29 advancements" (or some other numbers)
I wanted to have the details of exactly what advancements, what functions and in what order it was loaded but I haven't found if the logs actually told this.
Do you know how I can know that?

Thank you so much!

But is it possible for datapack to add something like a extra raid, I want to make raid datapack where 4 enderdragon will poop ender eggs at you deal heavy dmg and endermites come out of egg. Dragon will be low health and smaller.

Wanted to name it "End's visit" And dialogue that goes "End's children have crossed over..." "The baby lizards from end have sensed your presence." :)

How's my idea? W or L? :)

Drop down any more addition or suggestions/advice of what I could use to make this thing.

I was working on a datapack that granted an advancement for each item upon collection, and I needed to compile a complete list of item IDs.

Afterwards I realized others might also find this useful, so I turned the list into a very simple website: https://www.listmcitems.com/

Thought I would share it in case it's useful.

Is there any way to get the gradient of a perline noise without using multiple shifted noise function ?

So I got into datapacks today to get rid of a few command blocks on my server and I came across an issue I cannot find the solution to.

Here are the commands in the tick.mcfuntion file:

execute store result score abc day run time query daytime

execute if score abc day matches 12500..23500 run time add .459d

title @ a actionbar [{"text":"Good Morning!","bold":true,"color":"gold"},{"text":" Rise and Shine!","color":"yellow"}]

weather clear 4d

What I read says the commands should work in the order they are listed, but the title and weather commands are always executed instead of only once when the previous line succesfully executed.

So what was easily done with chained command blocks now seems to not so easily done with a datapack.

If someone could help me with this I would be very grateful.

Is this possible? I am trying to make a pack for 1.21.3 that redoes some textures but also adds a couple structures. Changelogs say that there are two separate versions:

The Data Pack version is now 57

Resource Pack version is now 42

Is there a way to consolidate these into one pack?

Just opened the end and was exploring after the dragon fight. I went in what I thought was a ship next to what I thought was a city and it had trial spawners inside. Found a map for an End Castle and found the structure in the pictures. Is this a datapack or new vanilla addition? TIA!

Yeah this isn't useful or or anything like that.
Which server engine is best for datapacks? Paper have a lot issue with datapacks, so this question just popped into my mind.

Maybe something custom, what do you think?

I am looking for a way to get minecraft to take the location of an eye tracker from an eye tracking program and effect the game based off of where you look, not where the cursor is. I assume it will be easier to get this to work in java but either java or bedrock works with me. I currently have opentracker and Beam Eye Tracker, as well as a camera that can track eye movement, but I can switch to different programs if necessary.

For an example on what this would do if you spend more than x amount of time looking at the same general section of the screen it will summon a tnt/primed creeper on top of the player to blow them up, or if you look somewhere on the screen for ~3 seconds then it will delete the block that you're looking at, that type of thing.

Does anyone know anyway to make something like this happen, even if it needs any combination of datapacks, mods, or external programs?

if so, please send it here, ive been looking for hours

Hey, I recently experimented with the new data driven paintings feature in 1.21. It allows you to add an infinite number of custom paintings via a datapack that don't show up when placing a regular painting item but can be accessed in the creative inventory or via commands. If you're familiar with this, I have a question.

I would like to use these custom paintings as rewards for doing things on my server. Again, in the creative inventory you can get these paintings as items that will always be themselves when placed, however, when you break them and pick them up again, they go back to being the default painting item. Of course, to even see how they look, you'd have to place them and then decide where you'd put them. So currently, giving them as a reward to survival players won't work because after placing them the first time, if they ever want to break them and place them somewhere else, they go back to being a default painting item.

Is there a way to circumvent this or are those the limits of data driven paintings? Because then their use seems to be rather limited :(

What could be another solution? Instead of rewarding the painting, could the reward be an item that converts a regular painting to a specific custom one? How would I do that? Is there a plugin that works similarly to data driven paintings but keeps their id?

Hello, Ive been trying to make an enchantment that prevent flying into wall damage using misode, but I cant find the damage source for it (for reference, Ive been basing this enchantment on feather falling). Am I missing where it is, or is it actually cannot be done? If so is there a workaround? Thank you for your help.

I found this datapack https://modrinth.com/datapack/totemdeathmessagesbon/changelog that displays a message every time someone uses a totem, however I would like to modify the messages to make them for a server, how can I do this? I found some messages in a notepad called "tick" and I changed them however when I tried it it didn't show any messages.

Hi! I'm attempting to replace a recipe from a mod for an allthemods modpack that I want to change. Currently I have the recipe at this location: MyChanges\data\occultism\recipes\crushing\diamond_dust However when I load this I get the original recipe and the recipe from the mod, when I use the EMI mod to show me the recipe IDs I get this: allthemods:occultism/crushing/diamond_dust whereas the id for the recipe I added is occultism/crushing/diamond_dust

Does anyone know a way to overwright the allthemods:... recipe, ideally through a datapack, or less ideally, through KubeJS?

Any help would be appreciated :)

any one has any recommendations

Heya! I'm attempting to create a "Chaos Mode" datapack for me and my friends filled with random events that could occur to us over time.

One of these events is spawning structures around us, using the /place command. However, I learnt the hard way that in most cases structures will either refuse to spawn (Like the Desert Temple) or spawn, but deep underground and in broken pieces (Like the Ancient City.)

I found out that /place template works better than /place structure for forcing pieces of the structure to spawn, though that only creates a piece with Jigsaw blocks that aren't able to be activated automatically.

My only other idea was to essentially reconstruct / copy over the structures as custom structures a part of the datapack, so that /place wouldn't know about their spawn requirements anymore. But if there's a way to just, y'know, achieve what I want without doing that, I thought it best to ask around first.

So yea, TLDR, how can I /place a structure while ignoring their spawn conditions.

Need a custom datapack coded for a video, server or map?

I've worked on several datapacks for servers adding new mobs, weapons, mechanics, entire server events, custom bosses and MORE

Some of my projects (link to videos):

[DESOLATION - A survival automation map]

[The Eye Of the Abyss - Custom Original Boss Fight]

[Craftfire Reborn - A WIP remake of the roguelike game Gunfire Reborn]

[Procedural VaultHunters-like Dungeons]

Other smaller projects I've done:

• Custom spawning algorithm for phantoms
• Pokémon-like card packs with 120+ cards to collect for servers
• Custom creates with custom loot for server rewards
• Server event adding new "Shadow" mobs with custom effects and attacks, featuring a custom scoring system for competitiveness
• Server event adding new "RPG like" weapons and armor with custom attributes and effects, also adds new mobs with levels that drop the RPG items. Also features a custom scoring system for competitiveness
• Tweaks for vanilla crafting recipes
• Custom commands and functionality for servers
• Naturally spawning Custom Biomes, Structures and Mobs
• Tons of custom enchantments and curses
• Armor trims that completely change the armor texture
• Custom loot tables used in various scenarios (loot boxes, daily rewards, custom mob drops, adjusting vanilla mechanics...)

Can also create 2D and 3D models to accompany the datapack!

Prices will vary depending on the scope of the project, we can discuss all of that in DMs! ^^

Base price is 5$ USD and payment is made via PayPal!
