Humanity has always dreamed of traversing the universe in search of unknown planets and moons. And now, this is to some extent possible in vanilla Minecraft!
The Expansion adds 7 space-related dimensions, more than 10 structures to find there, 3 vehicles, a lot of custom items, tools, weapons, machines...
... and a whole load of other features!
Getting started
- Don't forget to download and install the resourcepack!
- Look at The Moon at night with a spyglass while holding a book and quill in your offhand.
Compatibility
- The Expansion is compatible with versions 1.21.5 - 1.21.8
- The Expansion is multiplayer compatible.
- The Expansion does not work on Minecraft Realms.
- I don't recommend playing this on a Paper/Spigot/Purpur server.
- Use The Expansion with Aternos at your own peril.
- If you do decide to play on Paper, setting the "entities.armor_stands.tick" to false will break stuff.
- The Timber Strike Enchantment datapack seems to break my rightclick detection, don't use it with The Expansion!
- Do not remove The Expansion from your server once installed. Removing the files will break your server.

Have something to say?
I also want to ask how you'd feel teaming up with modders and maybe try to port your work to forge or something. I know it's a weird question, but i cannot find anything that replicates what you've done. It is so fenomenal how you manage to perfectly balance everything and implement fun and interesting features that are totally worth traveling between planets to get to. I just find it sad that the unsupported versions are so unstable. Either way love your work! You're amazing
A mod port has been a popular request lately. Which is fair, the project has become so large that the datapack is cracking at the seams. It's becoming rather hard to maintain this 6 years old codebase as well, hence the instabilities. I am also struggling a bit with the new Minecraft drop system because it demands a lot more work. However, I do like showing off which crazy things are possible within the limitations of datapacks and generally love making them. Personally I am not very interested in making a mod port. To me The Expansion is a whimsical passion project in which I can freely release my creativity, without strings attached. I think I'd also prefer making my own games over creating a mod.
I'm very glad to hear you like my work! This is a great motivation for me to continue the project. I have a rather large backlog of features that I still want to add, so the journey continues!
Small question however. How compatible is the datapack (and resource pack) with Optifine?
