BiomeReplacer

BiomeReplacer is a versatile tool which allows you to conditionally replace certain biomes in The Overworld and Nether with different ones it does so with the use of ReplacementRegions that take in values such as Size and Rarity to dynamically swap out one biome for another this system is fully compatible with other mods which alter MultiNoiseBiomeSource such as Terrablender and shouldn't cause any issues

Usage

you can use ElysiumBiomeRegistry class to add replacements, this class should be called inside of your Forge ServerAboutToStartEvent

your options are either replaceOverworldBiome or replaceNetherBiome

    @SubscribeEvent
    public void onServerAboutToStart(ServerAboutToStartEvent event) {
        RegistryAccess registryAccess = event.getServer().registryAccess();
        ElysiumBiomeRegistry.replaceNetherBiome(Biomes.BADLANDS, Biomes.SOUL_SAND_VALLEY, 0.5, 24, registryAccess);
    }

Variable	Description	Takes In
biome	the replacement biome that you're trying to add	ResourceKey
canReplace	the biomes this ReplacementRegion can override	ResourceKey
rarity	a double value between 0-1. it defines how rare the ReplacementRegions are	Double
size	the size of this current ReplacementRegion	Integer
registryAccess	lastly, you need to pass in a RegistryAccess	RegistryAccess

Tip

for size 24-32 is recommended for actual biomes and 16 for sub-biomes but play around with the values until you're satisfied with the placement

Example

that example provided above results in 50% of Soul Sand Valleys being turned into Badlands which are represented by the purple colors on this noise-map. it leaves the other biomes completely untouched letting you functionally have multiple biomes generating in your world that use the same noise parameters with precise control over what it can and cannot replace

Future Plans

Important

everything you see down here is subject to change!

for now only one Biome can be passed into canReplace but in the future tags can be defined in these too to allow replacement of multiple similar biomes
