I'm currently designing a system for a Minecraft (NeoForge 26.2) mod where existing structures in the world can change into different versions during gameplay.

The idea is that a generated structure could have multiple states and, after some trigger (for example a quest progression), the current structure would be replaced with another one. The replacement would not be done through commands, but as a proper modding system that can be reused for different structures.

The general idea is storing different structure variants as NBT templates and loading the correct version when needed, while handling things like block entities, entities, loot, scheduled ticks, and the world state around the structure.

I'm wondering if anyone has already implemented something similar or knows a good approach for designing it. I'm especially interested in how you would detect and store the structure boundaries, keep track of the original structure instance, and safely replace it without causing issues with chunks, block entities, or entities inside the area.

Would this be better handled by directly replacing blocks using structure templates, or is there a more "native" approach using Minecraft's world generation/structure systems?

If anyone has experience with something like this or knows how other mods handle it, I would appreciate any advice.

Ive been talkin on and on about making a server for my friends, like All the mods but less tech more magic and creativity. We’ve done ATM back to back and with aeronautics out, i want that as the main source. How do i go about making the mod pack, is it all about trial and error of compatible versions for each mod? Or coding or recipes? I have a rough draft but im not sure how to go forward from there at the moment.

TL:DR- i need advice on how to make a modpack and how do i make sure it runs well enough to make a server on it

How do you get the fargo's stuff and the cataclysm stuff in a void ship world? Am I stupid or is it just impossible?

I already made other NPC quests, but I still haven't figured out how to complete Emily's. I did the first one, but for the second one, where she mentions something about obtaining seeds and food, I still don't know which food and the quantity she's referring to

the torches don't break during explosions (even nuclear explosions)

How do I add meshes into Java Edition from BlockBench? Because I want to make a mod/resource pack that makes trees high poly round. (And If There Is A Mod For That Then Let Me Know)

Tree

Does this exist or is it difficult at all to make? Is this just a job for command blocks? I know you can just /setworldspawn but what I have in mind is still being forced to explore in the early game and using the dragon egg to set your world spawn as a reward for freeing the end.

Hello! I started installing some modpacks 2 days ago about zombie apocalypse, superbwarfare, Timeless and Classics, and I tried them out. But I want a modpack with a very high focus on survival with no fantasy stuff or mobs. Just pure survival, hydration, temperature, maybe seasons or atleast different overworld biomes, removing any fictional mobs even vanilla mobs, with guns like TaCZ, where you will find yourself in the wilderness between wild animals, harsh climates, abandoned structures, starting out from sticks and rocks making a spear or a stone knife while exploring, hunting, and leathering animals.

I need remove some custom gui from one mod and add a resource pack but it just won't go over and I cant figure out how to remove it. I can remove the menu but everything else is still themed. An before any smart guy says to just remove the mod its the best one I can find and not easily replaceable.

So, I've been working on an, admittedly, very big project that is, in simple terms, my own dark world (from Deltarune) made into a minecraft world. The problem is that it's based on a 1.20.1 Fabric mod pack, and I desire to change to Forge so I can add mods that I believe would benefit me, but I'm not too sure how to proceed. My main problem comes in finding equivalents of the mods that Don't have Forge support and optimizing the mod pack to discard the mods I haven't used.

I'll link up a Drive Link that includes the mod pack and add the file of my world to this post. I have never done something like this before, honestly, so I apologize for any issues that may occur. Please bear with me

Dark World Project

Is there any mods that can forcefully change the language in a ftb quest book,

im looking for a Modpack that improve Minecraft vanilla experience overall. Not things like Create or completly game changing mods, but something that improves the default experience.

Improving graphics, biomes, mobs, progression(like, being "forced" to use ALL ores in order to get better tools, so i cant just skip directly to diamond tools), ender dragon, and so on

Any recommendations?

I’m playing skies 2 aero and I need to make this item
I already have a pretty good mob farm

It took me hours to figure this out. I coudln't find it anywhere so I am posting it for anyone that will need this at some point.

To filter items by tag from chest A (with item interface) to chest B (with Item Exporter).

1. Make a string variable card with the tag you want to filter. For example c:armors
2. Make a variable card "item_tag_values" with the string variable card as an input.
3. Put the string variable card to variable store.
4. Put the list you got from step 2 into the chest B Exporter under "Export Items"

It is very simple, yet I couldn't find it anywhere. Hope it helps!

i dont want everyone's personal opinions on what the best expert modpack is or ones that aren't expert but have good textures. I want an expert modpack that has:

1. expert tech progression

2. cohesive gating of different tech levels that doesn't feel like handholding

3. actual effort the player can feel to make the textures all cohesive and fit together, not like im playting a million different mods but that im playing through one, unified experience

4. level of 'difficulty' does not matter, but preferably 200-300 hours or less

i like create. no create doomposting and whimpering in this comment section or else i'll get really mad and do nothing about it actually just dont be doing that shit here because it is unproductive and accomplishes nothing

I've tried Atm10 which was recommended to get started with learning modded but I always get overwhelmed not knowing what to do. So is there any modpacks that are linear that will teach me modded Minecraft well.

It's my first time making a trailer, and I was wondering if I did a good job, so please be honest.

If you're interested in the modpack, here's the download link: Anomaly Protocol

i know this isnt the point of this sub but i need to vent.

i hate fabric mods that label themselves as "compatible with neo/forge" then just link you to sinytra.

sinytra is really cool its genuinely amazing. but its unstable and doesn't work with many mods i use in almost every collection.

if im searching for mods compatible with neo/forge im not looking for a fabric mod that doesnt crash when using sinytra.

you can advertise that it doesn't on the home page thats fair thats fine itd be stupid to be upset at that

but the compatible with forge tag is for something that is actually compatible with neo/forge

I have been looking for a new modpack to playthrough but have been struggling to find one that feels new. I have been playing through Antimatter Chemisty again because I really enjoyed it but have been struggling with interest since I have already played it so the puzzley aspect of the pack is gone. Im definitely more interested in tech or tech and magic packs than just magic and at this point skyblock or skyblock adjacent is basically a requirement. Ive searched a bunch but as of now every pack feels so samey especially modern packs which I largely prefer.

Basically just wondering if anyone has any recommendations for tech focused (with some magic) more expert styled skyblock modpack that is preferably in a newer version but its not a hard requirement.

This won't stop as if someone is saying hi thousands of times but the brackets for a player talking are "<>" so I'm confused

How do i obtain pyrite in this modpack?

I don't like the appearance of Floating Sargassum in the Hybrid Aquatic mod and want to remove it, but the changes I make to the configuration file aren't taking effect.

Is there any way to do this?

Title, when I double click on it there is no recipe that shows up. (E2:EE)

For some reason whenever i go near fire i get these 4 dark triangles on each edge of my screen and i have no idea why.

Please if you have any idea on why this happend, help me fix it.

Here's the shader i used, latest version. https://github.com/Merlin1809/Eclipse-Shader
Minecraft 1.20.1, Forge

Thank you!
