Larion: Disc World

This is a simple add-on for my Larion World Generation mod that limits land generation to a circle of approximately 3500 blocks in radius. The shape of the landmass(es) within this circle vary wildly between seeds. 90% of the time, most of Minecraft's biomes are present despite the limited world size.

Only two files from Larion have been changed to make this possible - continents and the temperature sinewave, which has been made slightly smaller and capped so it doesn't repeat.

This mod/datapack depends on Larion to work and must be loaded after Larion. If you use the Fabric mod versions, this should happen automagically, but if you use the datapack versions, you may have to look into Paxi or similar tools to get them to order correctly.

You may have a hard time finding woodland mansions - if your world has none, you'll have to create one yourself with cheats!

If you want to make the generated area larger or smaller it's easy to do so, just edit the file data/laron/worldgen/density_function/overworld/circle.json file and change two really small numbers (0.0002) to something else, or even make them differ from each other for an ellipsis world.

The number corresponds to the disk radius in blocks to the power of -1. For example the default radius is 5000, because 5000^-1 = 0.0002.

You can adjust the other small number in temperature_delta.json to fit with the new size. This one relates to the "length" in blocks of the temperature curve like this: number = length^-1 * 3.14
