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

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.
