Infinite Sky Dimension

A vanilla datapack that fills the sky with endless, unique floating islands – no mods, just logic.

Walk in any direction and the world builds itself around you. A 3×3 grid of armor stands follows the player, generating 9 completely random islands every 80 blocks. Old islands never disappear. The sky becomes an ever-growing, one-of-a-kind dimension.

✦ How It Works

This datapack uses a custom chunk‑like system built entirely from armor stands and functions.

• Player‑centered grid: A 3×3 grid of anchor armor stands is constantly aligned to your position. The grid cells are spaced 80 blocks apart, covering your full render distance.
• Island stacks: Each of the 9 grid cells contains a vertical stack of 20 armor stands. Every stand spins and fires a fill command at its own radius – narrow at the bottom, wide at the top – to carve a layered, organic island shape.
• Double randomness:
  • Layer RNG: Every single armor stand rolls a random radius each time an island generates, so the silhouette is always jagged and natural.
  • Size RNG: The entire island also randomly picks one of 6 size tiers (0–5), scaling every layer by an extra block of radius.
  • Result: no two islands are ever alike.
• Infinite persistence: Islands are never cleared. As you move, old islands stay behind and new ones appear ahead. The sky fills up forever.
• Automatic trigger: A marker armor stand is dropped onto the island you're standing on. A tick function checks your distance to that marker. Once you're 80 blocks away, a fresh set of 9 islands spawns around your new location and the marker updates.

✦ Technical Details

Stat	Value
Total armor stands	190 (9 grid anchors + 9×20 orbit stands)
Functions	25
Grid size	3×3 (80‑block spacing)
Island sizes	6 random tiers (0–5)
Layers per island	20
Namespace	maniac
Min/max game version	1.21.10

No command blocks are required in‑world. Everything runs directly from the datapack.
All heavy work (fill commands) happens only during generation, so performance stays smooth during normal gameplay.

✦ Installation

1. Download the datapack .zip.
2. Place it inside your world's datapacks folder:
   .minecraft/saves/<your_world>/datapacks/
3. In‑game, run /reload.
   The generator starts automatically – no extra command needed.

Note: This datapack is designed for vanilla Minecraft. No mods, no resource packs, no datapack dependencies required.

✦ Usage

Just walk. Islands will begin appearing around you.

• The island you're standing on will have a small marker armor stand (it's invisible and silent).
• Walk roughly 80 blocks away from that marker to trigger a new round of generation.
• There is no cleanup. Every island you leave behind stays in the world forever, turning your sky into a dense, personal archipelago.
