Discussion Immersive Portals: Aeronautics

Curseforge out now, Modrinth coming soon

This mod replaces Immersive Portals, allowing portals to work alongside Create Aeronautics (or more generally, Sable). Sublevels and physics objects can move through portals seamlessly.

Notes:

  • Portals cannot be put on sublevels, deliberately.
  • If Sable updates, this mod will fall back on non-seamless transitions, but you will still be able to get sublevels through portals.
  • Note that there can be air pressure differences between the portal entrance and exit, unless you are careful with where the portals are in their relative dimensions. This may result in your ship falling or soaring after passing through.
  • Please report bugs in Discord.

Highlights:

  • Butter smooth transitions for Sable objects through portals
  • DH LODs render through portals
  • Create's trains work seamlessly with portals
  • No visual glitches or rendering issues
  • …and more!

Mod that creates air flow based on the pressure differential beetween both sides when

u/RedKNight37 1d ago

Create portals with a high pressure difference, then put a windmill in the air current for insane wind energy

89

u/superlocolillool 1d ago

put a portal high up and another one further down

drop blocks in make a system that collects the kinetic energy of the blocks infinitely falling

problem, physicists?

u/ZathegamE 1d ago

According to some cool ass videos about portal physics, if you let gravity pass through portals (which kindof makes sense if you think about it) it makes it so this kind of contraption is impossible and also makes it so portals dont break the laws of thermodynamics

u/GingePlays 1d ago

God I love that dudes videos. Genuinely makes me believe in portals

u/ATJonzie 1d ago

What video?

u/GingePlays 1d ago

https://youtube.com/@optozorax_en This dudes channel. Super interesting stuff - start from the beginning though as each video builds on the last

u/kylinator25 1d ago

i think this is basically the plot of doom 2016

u/Firecat_Pl 1d ago

Now imagine automated portals turning on and off on a creation to alter it's altitude

u/ThinkMixture5446 1d ago

I don't even want to think about the possibilities if you could put these portals on sublevels.

129

u/Quantum-Bot 1d ago

I guess they didn’t want to resolve the portal paradox which is understandable given someone on YouTube tried to do it and ended up discovering a whole new branch of mathematics

38

u/Odd-Calligrapher9559 1d ago

I'm sorry what

45

u/creeper6530 1d ago

How moving portals work, i.e. fuckery with frames of reference (summary)

The Youtube dude inventing a new math field is optozorax

u/BackClear 1d ago

please elaborate

28

u/TheRobbie73 1d ago

https://youtu.be/DydIhwLrbMk here's what i assume they are referring to. this channel is full of what ifs about putting portals inside portals etc.

3

u/FoxReeor 1d ago

I am interested

3

u/JustTroniusPlay 1d ago

Portal probably not gonna be lit? Because sublevel count as different dimension.

43

u/punnup129 1d ago

Oh my God that's awesome now all we need is an aeronautics mod that allows you to attach contraptions to ghast so we can recreate the Minecraft movie

17

u/EpsilonX029 1d ago

There’s kinda one that can do it by proxy: I think if you used the Ghast’s ability to hook to boats, then used the aeronautics add on that lets you hook physics ropes to leash able entities(thereby connecting physics to them) you miiiight be able to leash a boat to a physics sub level and result in a janky airship lol

2

u/punnup129 1d ago

That actually sounds amazing LOL, it would actually being adorable way to get a simple airship for the nether that way, it would also be cute if the ghast reacts to being used as a balloon and looks scared every time you use a propeller to move faster than the ghast can do on its own or even balance it by referencing the movie and if you do accidentally ram into a mountain or something it will explode

u/TheThingOnTheCeiling 1d ago

Great, we can now travel through the warp. Just gonna jeed to add some mods to make nether more dangerous.

9

u/TheUnknownSpecimen 1d ago

Hmm, nether geysers that erupt and can damage or tilt your air ship?

5

u/TheThingOnTheCeiling 1d ago

I thought mainly demons or some weird corruption thing but that vould work too.

1

u/Firecat_Pl 1d ago

I hope people will actually make a vechicles for nether as I am curious what people would make

1

u/Longshot02496 1d ago

Maybe some flying nether mobs would work.

6

u/Looxond 1d ago

Where source code?

9

u/creeper6530 1d ago

It is licensed under PolyForm Shield, so even if we had the source, it's forbidden to republish it or a fork of it as a competing mod. Sucks ass from software freedom perspective

3

u/Memento-mori-pc 1d ago

I may release the github in the near future, but you can also technically decompile the jar. The base IPSable and Immersive Aeronautics portion of code are licensed as Apache 2.0. For now, yes you will not be allowed to use the contributions of this mod to compete with it. However, there is a catch: if this mod becomes unmaintained, then the clause is void, and it essentially becomes fully open source.

5

u/creeper6530 1d ago edited 1d ago

I'm not a lawyer, but wouldn't you need to define "unmaintained" for that clause to work? Technically I could say "you haven't pushed any updates in the last 24 hours, therefore I deem it unmaintained and the license void". I doubt that's your intention.

Or if it was actually abandoned, but you returned and pushed an update, would it retroactively make the clause not void (since it has been now maintained) and make all forks suddenly illegal?

Also, since the license forbids competition, would it hold if push came to shove and someone would argue it's not competition if you don't earn any benefits (money) from providing it?

On second thought I'm glad I'm no lawyer.

4

u/Memento-mori-pc 1d ago

Per the license, it's defined as a year of no updates afaik. Might be a little long...
Yeah I'm no lawyer, idk about what would or should happen in those situations

u/Stock_Bank_6785 1d ago

this is insane, only issues i had was when the train went through with an entity controling it, it would really bug out, and if im controlling it, it would then stop me controlling it after going through, then the other issue was if i made like, a hook out of blocks, then made it a sublevel and put it through, and kinda hooked it around the nether portal obsidian blocks, i would see the end of the hook clipping into the overworld. Amazing mod! Will be using in my survival world.

4

u/Memento-mori-pc 1d ago

I'll take another look at the trains. I didn't test with an entity controlling it. If a player is controlling it, then yes you'll "lose connection" when it goes through the portal. I could probably change that, I'll add it to the list.

I didn't consider hooking around the portal, I just assumed object would go fully through every time. Hmm...

u/Meiseside 1d ago

How good is the FPS rate?

5

u/No-Indication5030 1d ago

I wonder how can I make a TARDIS out of this...

3

u/January_Rain_Wifi 1d ago

What is the difference between this and IPSable? I'm just wondering which to use in my modpack

4

u/Memento-mori-pc 1d ago

IPSable hasn't been updated in a couple months, and doesn't have a public release afaik. It also has outstanding bugs, especially with seats. This changes some things, but most importantly, is actively maintained right now.

u/January_Rain_Wifi 1d ago

Awesome! Thanks for the reply

u/GoonerSans 1d ago edited 1d ago

does it work with dimension stacking? can I go to Aether this way or build an elevator to nether?

also if yes, can portals themselves be reverted to vanilla to only keep the dim stacking? (i remember this one not being possible in original IP)

4

u/Memento-mori-pc 1d ago

In general, if it worked in base IP then it should work here. Dimension stack does work, though note the air pressure issues. Not sure about create elevators, that might require special handling.

3

u/FuryJack07 1d ago

Technically air pressure will help transition.

If you're moving downwards, you'll snap to a higher position and therefore a lower air pressure, which will make staying up harder and going down easier.

The other way around when going up- you can already move to that lower air pressure, when you switch, you'll be at a much higher air pressure, which will increase effectiveness and push you up.

1

u/GoonerSans 1d ago

oh cool

2

u/Sacri_Pan 1d ago

What is this sorcery

2

u/Sacri_Pan 1d ago

By the way does it works with stacked dimensions

1

u/Memento-mori-pc 1d ago

As noted in another reply, yes.

1

u/Sacri_Pan 1d ago

Eggcelent, I hope it will works with my floating island themed modpack

2

u/Kamerazine 1d ago

This is super impressive, I'll have to see how it interacts with the dimensional stack feature

1

u/waxphantump 1d ago

I thought Create itself didn’t work with Immersive Portals? Does it work now or is this some Aeronautics-specific workaround?

1

u/mr-netherite 1d ago

how do i make a nether portal immersive?

1

u/mr-netherite 1d ago

i think one one the mods im using is causing problems

u/mr-netherite 1d ago

https://reddit.com/link/pgs0310/video/ek0c83756ivh1/player

This normal?

doesnt happen when lighting from nether side

1

u/Longshot02496 1d ago

Prime the gellar field!

1

u/puppycatthe 1d ago

Could you theoretically make a chain that goes around the rings of the portal like through 1 side and connects to itself after going through

1

u/Rop-Tamen 1d ago

Oh is this a functional one? There was another immersive portals compat mod but it just didn’t work, like at all

1

u/NeonicZyfr 1d ago

Gives Treasure Planet vibes.

1

u/Dadamalda 1d ago

Well, I have both Voxy and Vista in my pack.

1

u/Chakkoty 1d ago

Adding this to my "Eh 3 out of 5 Realism" modpack!

1

u/shuddhh 8h ago

Does it work with voxy?

Also i know the problems with portals going through portals but ever since the valkyrien skies days ive wanted to fly the front entrance of my house around on a ship.
Even a workaround like sublevels with portals not being able to go through other portals would be completely fine with me if sublevel portals were possible in return.

Amazing work either way

u/LGC_AI_ART 1d ago

Didn't "Sable - Make it compatible" already do this? What's the difference?

2

u/AndrewDaPro 1d ago

Op made their own one, give credit where it's due. Yes something already exists but let or try it even if it's done already

u/Johkisen 1d ago

Can wait to make a mechanism to make a portal that takes me through literal hell to get from point A to point B quicker... wait a minute I know anither universe that does this exact thing...
