Ad Astra version required is (alpha) 1.15.16+ (x.18 recommended)
Remember the time when we had mods to unify 5 different kinds of copper ore added by different mods?
The future is now; when we need a mod to unify 5 different kinds of venus planet added by different mods!
This mod at its core just replaces the redundant dimensions from different space inspired mods into a single, unified one. This unified dimension shares (most) rules of what biomes, structures, ores, methods to breathe, mobs, gravity, and other bahaviours youd expect from each planet, for reference, see the content from each mods wiki/resources. Also, those unified planets float above the void, they use a beutiful skyland inspired terrain generation, because feels more fitting for space, imo.
You can travel to these new dimensions using either Ad Astra or Creating Space, you will NEED an Ad astra chestpiece to breathe (for now), but the rest of the spce suit can be made with any piece of other space suits!
CURRENT FEATURES:
-Oxygen and gravity without conflicts, spacesuit anyone?.
-2 kinds of Rockets!, contraption-based (custimize it block by block) ones and craftable ones (Creatingspace and Ad Astra rockets, respectively)
-All the 8 planets from the Solar System, + Our moon. (More celestial bodies "soon"). And their orbits
-Customizable (with datapacks).
Everything is writen manually in the "datapack section", meaning, you can customize my dimensions further with a custom datapack. (No documentation, open the compressed .jar and look inside /data for reference)
-Orbits! Most planets have orbits you can travel to using either type of rocket, and even atumatically generate a landing structure (with ad_astra rockets specifically), you can also drop down into the planet seemlessly.
-Mods (partially) integrated are; Ad Astra, Creating Space, Space Dimensions, Osmium Space Program & Northstar.
PLANNED FEATURES:
-Breathe in space with means other than Ad Astra chestplates.
-More celestial bodies; moons, dwarf planets, planets outside our solar system...
-Finish removing/integrating vestigial features. Id recommend sticking to Ad Astra and Creating Space methods of travel and Ad Astra methods of breathing for now and there shouldn't be any edge cases, sorry for the inconveniences already.
-Integrate addons too.
-Fix for once the carvers replacing some air for lava making unintended floating lava rivers on the bottom of some biomes.
-More polish for the currently implemented dimensions, like more differenciated terrain and biome placement, ofc, I need to get back into studying for now...
SPECIAL THANKS!
All the modders who make this integration possible in the first place, check the "Relations" tag if you are in the browser. You are gonna need it anyway if you aren't downloading from the mod manager.
To Apothicon; double thanks for the skyland terrain generation. Go check out their mods, maybe you find the beauty in Earth before flying off! Seriously!
