Rainbeau's Sky Islands (New Dimension Version)

A World of Floating Isles Hovering Over an Endless Sea

(A Data Pack for Minecraft 1.19)

In vanilla Minecraft, the sky is just... empty. There's so much of it, but there's nothing in it.

Well, no more! Now, the sky is full of flying islands, which is actually a good thing, because the world's surface is just water.

Amongst the islands, you'll find variations on most of Minecraft's vanilla Overworld biomes. But that's not all. Whatever cataclysm created this bizarre world of gravity-defying land masses tore through the walls separating dimensions, and so you'll also find islands that don't belong in the Overworld at all, such as islands of netherrack and basalt, populated by piglins, islands of end stone, populated by flocks (herds? gaggles? murders?) of endermen, and even islands of prismarine and sandstone, populated by, well, honestly, not much at all.

But don't make the mistake of thinking that you can just jump off the island you spawn on and swim to one that you like better. Aside from the question of how to get back up from the water to your intended new home, there's the fact that while the dive into the ocean won't necessarily kill you, it's unlikely that the drowneds and guardians who make the sea their home would be so considerate.

And speaking of unfriendly denizens, be aware that far more villages than you're used to have been abandoned to the ravages of the undead. Don't assume that you've found a safe haven, just because you see houses on the horizon.

You'll also find that all ores, gems and stone types can be found at any elevation. Given the nature of the world, elevation-based limitations really don't make much sense. This might seem overly generous, and certainly, for example, it makes it potentially easier to find diamonds early in the game. But bear in mind that there is substantially less mineable rock on a "Sky Islands" map than you're used to. Large-scale strip mining is literally impossible. So later in the game, resource scarcity is likely to become an issue, even given the adjustments I've made.

Along similar lines, and for similar reasons, I've adjusted emerald ore so that it now spawns in any "Sky Islands" biome, rather than just in "mountains," which is frankly a rather meaningless concept now, anyway. But to keep things interesting, I've also adjusted infested stone (the type of stone from which silverfish emerge) so that it, too, can appear anywhere.

This data pack should be compatible with pretty much anything. However, since it uses custom biomes, any mods or data packs that alter or add things to vanilla biomes won't affect "Sky Islands" biomes. My own "Flying Villages," "Ocean Villages," "Ships On Seas" and "Undersea Villages" are exceptions to that rule, as I've specifically made this pack compatible with them, but be aware that as "Sky Islands" terrain generation is much more chaotic than that of vanilla worlds, I can't guarantee that you won't come across oddities like villages simply embedded in islands.

ACCESSING THE "SKY ISLANDS" REALM: You can access the new dimension via a portal constructed with polished granite blocks and activated with a flint and steel. But be careful! As portals connect to the same coordinates in both dimensions, it's easy to create a portal that isn't particularly useful. (For example, if you were to construct a portal on a high island in the sky islands world, you'd go through it only to find yourself at the other side on a tiny platform hovering far above ground in the Overworld.) You can build a portal in any of three different sizes, depending upon your style preference. You can use 10 blocks to create a 1x2 portal (the size of a normal doorway), 10-14 blocks to create a 2x3 portal (the size of a vanilla nether portal), or 12-16 blocks to create a 3x3 portal. Note that in the frame for a doorway-sized portal, corner blocks are required, but in the larger frames, corner blocks are optional. Automatically-generated return portals will always be 2x3, but can of course be rebuilt to match your preference. Included in this data pack is an optional "Rainbeau's Portals Resource Pack," which can be used to make the data pack's portals look a bit nicer.

CREDITS (Concepts): Special thanks go to Sanonasu. This data pack originated as an adaptation of his "Floating Islands" pack, and if he hadn't conceived of the idea and done the original world generation work, "Sky Islands" wouldn't exist! Similarly, the idea for the prismarine forest biome and the "petrified" coral trees therein came from the prismarine cliffs and petrified forest biomes in MC_DA's "Many More Biomes" data pack, and my crystal forest biome draws from that pack's frozen and crystallized forest biomes.

CREDITS (Portals): This pack's portal code is slightly modified from code originally written by Timber Forge for Minecraft 1.16.

It's probably worth noting that I have only a very vague understanding of how the world generation actually works. I took a "brute force" approach - changing different numbers in the file and loading the game to see what kind of effect they had, until I finally came up with a set of numbers that approximated the look of the original "Sky Islands" in a way I liked. But if someone who actually knows what they're doing can come up with a better set, I'm certainly willing to adapt. :)

This has now been updated for 1.19, but I've hit my "daily update limit," so I'll post an official update notice tomorrow. :P

As I just posted in response to your other comment, I'd be very surprised if you found any data packs released for 1.16.2, 1.16.3 or 1.16.4 that didn't also work with 1.16.5.

1.16.2 was the last "major" release, inasmuch as that was the release that added support for custom dimensions.

Updated to allow for multiple portal sizes, and to fix turtle spawning. The optional resource pack was also updated to improve the portals' look and to accommodate the new size options.

Looks great, going to try it out now, I think it's what I've been looking for all week.

I tried it out, and it is great.

Bug: found a place in the sky near an end (city?) tower that spawned many too many shulkers, I have a screenshot if you want to see it.

Sorry for the slow response. I get a notification when someone posts a new comment, but not when someone edits an existing comment, and so didn't know you'd provided new info. :)

I'm not sure what might have happened, as I don't edit end cities at all. They're simply called in the data pack they same way they're called in the actual End. But I can certainly take a look.

I should be able to see the problem for myself if you just give me your world seed and the location of the city in question. :)

Always excited to see your Datapacks because they never fail to enhance my Survival playthroughs. Keep up great work. Super flat or Better Cave dimension next? :)

It's not exactly caves, but I *am* about to release a "Creeper World" dimension. Started out just as something silly, but kind of became semi-serious as I was playing with it. Not sure it's worth working on anything too cave-specific, though, since the next real update is all about caves, anyway.

As to superflat.... What would you suggest? I've always thought superflat worlds were boring. Good for creative building, but nothing else. Not sure how to make them more interesting without making them, well, not superflat worlds any more.
