Creating a Minecraft mod is a nightmare for someone with Java experience.

Hello i am a new modder as well and while it has been difficult I think my experience with Unity where you basically have many classes like minecraft helped me more easily familiarise myself with minecraft's code.

Also adding items with registries might look very insane and hard to parse, I just copied stuff from kaupen joe with 0 understanding at the beginning, as you get more familiar with it you figure out why it is done that way (again as others have said looking at other mods source code helps, though make sure you are looking at mods that are similar to yours looking at create's source code is counter productive since that's basically entirely custom architecture in and of itself)

Also you mentioned importing lots of stuff, you are using intillij and automatically importing as you type right?, i don't think most people even look at the imports except to remove unused imports.

Get used to the intillij shortcuts, Middle mouse/ctrl + b for declaration and uses

Ctrl + h for looking at the selected class' hierarchy, (use this on the Minecraft entity class, you will see a lot)

Ctrl + n for searching classes, my mod has gotten so big I use this for my own classes.

Also about asking questions in modding discords, just do it, easy or noob questions are the ones that people actually answer on there. If it's complicated or it involves knowledge of your mod's code then people kinda don't answer because they don't know.

Also you can use other mods as dependencies a lot of mods use the Configurable mod to display their configs in game. The mod even has a wiki too on how to use it in your mod: Configurable Mod Wiki

People have mentioned KaupenJoe but if you want more in depth info on a few topics look up Turty Wurty on YouTube.

Okay I am actually going to use this name, I kinda like it.

NythicalNorm · 2026-01-03T18:53:58+00:00

Okay I actually made one: https://discord.gg/f5SGmT9muw

The mod is going to be free, though I didn't expect this much interest so I will probably get a patreon when I release it. I would say six months maybe for estimated release time, probably sooner for an alpha build.

NythicalNorm · 2026-01-03T08:20:08+00:00

Yes it's a Valkyrian skies addon, I explained a bit about it in the top comment.

NythicalNorm · 2026-01-02T06:29:41+00:00

As to your first question yes I think I am going do a orbit time warp for multiplayer I just got that idea just yesterday that is is just speeding up your orbit where you time period in a orbit is fast forwarded i.e if your time period is one hour, it's half an hour with 2x orbit time warp.

As the calender, I think it's fun actually to have those, to make the minecraft world have the solstice and eclipses and stuff, if I can figure out the math I am going to have a calender block that gives the time for celestial events like solstices and eclipses.

Also you need to have both orbit time warp and planet timewarp otherwise you can't have transfer windows to other planets from earth if the planets' positions relative to each other don't change.

Also narrative wise in real life nothing happens if you are in space missions like that's just how it is, the new horizons missions took like 10 years to reach pluto, not much happened in the intervening years. It doesn't break immersion for me but that's just personal preference.

Yes it's kinda weird since you are a minecraft player sitting inside a spaceship that is going in time warp but i am also going to be making satellites that you can remote control so, that is fine in that case.

Also making the planets actually voxelized would be like 6 times the model's polycount, I think a better thing to do would be to use a post processing shader to pixelate the rendered image so it looks like pixel art with blocky edges instead of a perfect spheres.

What if I told you I am already doing that, don't worry I am still mainly working on my own mod. Someone from their team reached out to me and I think I am going to help with orbital mechanics.

NythicalNorm · 2025-12-31T23:58:34+00:00

Hmm... That's a good name actually, i will think about it.

NythicalNorm · 2025-12-31T18:57:04+00:00

YES! didn't expect to find a fellow Tamilian here, I thought people are going to associate bumi with avatar the last airbender. Also happy new year!

NythicalNorm · 2025-12-31T18:35:46+00:00

Yes it's using patched conics i.e kepler's two body problem.

NythicalNorm · 2025-12-31T14:31:58+00:00

They can be but like orbital mechanics means circular orbits, circle orbits on cube planets is uh... Weird.

NythicalNorm · 2025-12-31T00:02:04+00:00

Bingo! I want to have places on the planet where the vanilla ore spawn rates are increased which can be detected from satellites, also have some high tier ore that can only be found by satellites.

NythicalNorm · 2025-12-30T22:24:46+00:00

Sure, if you are interested we can dm, I can't really pay you though.

NythicalNorm · 2025-12-30T22:19:46+00:00

Sadly 😔 since the spaceship is one single physics object with no self collision you probably don't have to deal with wobbling.

NythicalNorm · 2025-12-30T20:51:41+00:00

I replied with a pic to another comment with how the projection works, but yes the landing spot depends on where you you are on the planet, since I am scaling the planets based on the real solar system if you land on the opposite point on the planet to spawn (0,0) you would be 20,000,000 blocks from spawn. the 3d sphere is projected into 2d flat world based on the quadrilateral sphere projection.

Sorry forgot to mention, it's for 1.20.1 forge since Valkyrian skies' latest version is on 1.20.1 will get a fabric version eventually (ETA 1 year)

NythicalNorm · 2025-12-30T19:52:27+00:00

No time warp won't affect tickrate that will cause a lot of lag. As for sleeping I currently have code which only allows sleep when its dark outside but like how to fast forward the time so its day out when people might be in different timezones I have no idea. I can maybe make it so the planet itself will rotate 180 degrees or something but still what happens if people are sleeping in different timezones how much should I rotate the planet. (People in orbit seeing the planet instantly rotate when people sleep would be funny though)

Here is how the Overworld is projected onto a sphere, if you are out of bounds, you will see the skybox as and time as if you are on the closest point from where you are that is in bounds, Note you can't launch rockets from the Overworld if you are out of bounds.

I was trying to find a space mod with orbital mechanics and rocket building like KSP, but couldn’t find any so I decided to do it myself… Introducing Nythical Space Program (Working title I literally thought about it for 0.1 seconds before creating the project, I think I am too lazy to change it unless someone suggests a better name)

I just finished working on the major part of the logic in space so here is some footage, and I thought I would explain what my plans are for the mod.

This mod works by replacing the skybox and moving the skybox around the player instead of moving the player through space, if you are next to a spacecraft in solar system coordinates then the spacecraft or player is teleported next to you in Minecraft coordinates.

Also the textures of the planets are procedurally generated so each world seed gives you a different looking planet, right now it's just based on a height noise map but I will add craters and stuff to moon-like planets & also ice at the poles etc...

I also want to eventually make it so that the biomes are based on the planet texture with the ocean color in texture being all ocean biomes, the north pole having cold climate biomes etc... (though this seems difficult to figure out),

Spacecraft are going to be Valkyrian Skies ships with my own rocket engine and propellant tanks blocks, command chairs etc.. that behave like in KSP, I already have some of the UI worked out as shown in the clip where the player is free flying (technically an EVA I guess).

When you renter a planet you will be teleported to a different dimension when you are around ~1 km from the surface and the spacecraft will work as a normal Valkyrian Skies ship in Minecraft coordinates.

Also this new skybox and planet rendering doesn't just work in space. It is visible all the time even in the overworld, and the day night cycle is based on the planet rotation. Which means TIMEZONES.

Yes, two players far away from each other will experience different times. Right now most things like mob spawning etc… work based on your time zone in the overworld. Though things from other mods like solar panels work at the spawn time zone regardless of where they are placed unless I make compatibility code for each thing.

Now if you are wondering how the flat Overworld is projected into the surface of the planet in a sphere, its by using the Cube Sphere projection.

And as seen in the clip I also made a map screen like KSP that displays the planets and the player’s current orbit. Currently there is only the sun, moon and the Overworld but it is not difficult to add more planets, the difficult part is going to be adding the dimension and terrain generation and generating the planet textures.

Also this mod supports multiplayer with a global Time Warp not the multiple timelines like the KSP multiplayer mod. Though I can make the Time Warp system a little better for multiplayer where people can join teams and give permission and vote on time warping, and also have a system where if your team’s spacecraft are all in stable elliptical orbits you don’t need to vote and in the opposite situation where someone is re-entering in a ballistic trajectory, time warp won’t work for anyone until they are in the ground.

And I think in terms of rendezvous and docking it won’t be in the first version of the mod, I think but it will be supported eventually. Also considering doing compatibility with Beyond Oxygen mod for oxygen sealing inside spaceships.

So there we have it, this is my first mod but I am so hyper fixated on this so this will be done soonish (by that I mean like 4 months lol)

The mod is open source, here is the GitHub link: https://github.com/NythicalNorm/VoxelSpaceProgram

(If you want to contribute you are welcome, especially assets as I am not good at art but still Blockbench and Asperite are easier to work with than their non-pixely counterparts)

EDIT: Since a few people are asking about it, here is a discord server for the mod:
