I want to change conditions of choosing a biome.(e.g. Every chunk is a different biome.)

Which class should I extend?

And which method should I override?

Can anybody help?

I believe you would want to create a custom BiomeProvider and override the getNoiseBiome method inherited from BiomeManager.IBiomeReader.

 

This won't actually accomplish anything unless you have a ChunkGenerator which uses your BiomeProvider. The only way I know to do that is to create a new WorldType and employ the createChunkGenerator method to create a new instance of a ChunkGenerator when the appropriate DimensionType is being loaded. You likely want an OverworldChunkGenerator which accepts a BiomeProvider as an argument to the constructor.

 

I also believe new WorldType instances are registered when you call super("unique_name"). Just don't forget to actually create an instance of your WorldType when your mod loads. Then when you play you can pick your WorldType during world creation.

 

I don't have a working example in 1.15 yet, so I could have missed something.

I found the method!

Thank you!
