Old Continents Slider

[0.1.0] - 2026-07-21

First release. For Minecraft 26.2 with Fabric (requires Fabric API).

Added

• "Continents" world type with a Continentalness slider (0–100) (steps of 5) behind the Customize button on the world creation screen:
  • 0 = modern generation, identical to vanilla.
  • 100 = classic 1.6.4-style continents: ragged-coast archipelagos in a dominant ocean (~84% water).
  • Anything in between = hybrid worlds.
• Terrain built from 100% vanilla density functions (no custom chunk generator): worlds store a clean reference, stay stable across mod updates, and are safe to open even without the mod installed.
• /continents map <continentalness> [radius] (OP): renders a 1024×1024 PNG biome map of your seed at any slider value in ~1 second, without generating chunks (radius 1,000–30,000, default 10,000). Files are saved to continents-maps/ with a clickable link in chat.
• /continents map settings <id> [radius] (OP): variant that renders any registered noise_settings (useful for datapacks and experiments).
• Dedicated server support: level-type=continents\:continents generates at continentalness 100.
• Languages: English, Spanish, and Spanish (Argentina).

Balance notes

• The curve at continentalness 100 is calibrated against real 1.6.4 generation: fragmented landmasses (features ~2.9× vanilla scale), rugged coastlines, and an ocean-biased offset.
• Mushroom islands exist but are rare and small (deep-tail compression of the noise: only the most extreme cores cross the mushroom fields threshold).
