Old Continents Slider

!Replace this with a description

Remember when Minecraft had real oceans? Until 1.6.4, the world was big continents floating in a huge ocean. Since 1.7.2, it's an infinite landmass with elongated lakes. One of the oldest debates in the community — and this mod doesn't pick a side: you get a slider.

✨ What it does

!Replace this with a description

Adds the Continents world type with a Continentalness slider (0–100):

• 🏞 0 — Modern generation, identical to vanilla.
• 🏝 100 — Classic continents: ragged-coast archipelagos in a dominant ocean (~84% water), 1.6.4 style.
• 🌗 Anything in between — hybrid worlds: the higher the value, the bigger the seas.

Every vanilla biome, structure and mechanic works normally. Terrain is built from 100% vanilla density functions — no custom chunk generator — so worlds are stable across mod updates and even safe to open without the mod installed.

🕹 How to use

1. Create New World → World Type: Continents
2. Click Customize and move the slider
3. Create — the value is saved in your world forever

🗺 Bonus: instant world maps

/continents map <value> [radius]

Renders a 1024×1024 biome map of your seed at ANY slider value in ~1 second, without generating a single chunk. Compare generations side by side on the same seed.

❓ FAQ

• Multiplayer? Yes — works on dedicated servers (level-type=continents:continents generates at 100).
• Existing worlds? The slider applies at world creation only; existing worlds keep their generation.
• Performance? Same as vanilla — it's the vanilla noise generator with different parameters.
• Requires: Fabric Loader ≥ 0.19.3 + Fabric API.

Todos los biomas y estructuras vanilla funcionan normal. Incluye /continents map para renderizar mapas de tu seed en cualquier valor del slider, en un segundo y sin generar chunks.

This mod was inspired by Minecraft's Continent Problem by MISTYBUNGLER — a great video on the history of one of the community's oldest debates, which imagined exactly this slider. Go watch it!
