(Fabric 18.2) serverside mod biome modifier

[wispy garnet]

Hello guys. I would like to ask if someone is able to make a mod that has 2 features:

1. generating a new world will always have a specific selected biome as worldspawn at x=0 and y=0, customizable in a config file.

Example: a plains biome is selected in the config file, therefor only a plains biome can generate.

2. Prevent entire biomes from generating, also customizable via a config file.

Example: all ocean biomes are selected in the config, therefor no ocean biomes can spawn in the entire world.

If someone is interested in helping out, i would be very thankful!

the second one can be done via biome tags (with a mod to support that logic)

thanks for the answer.

anything about the first feature?

so just a single biome world? i swore this was a vanilla thing

or is it just no oceans and you select the biome you spawn in?

theres a mod that changes the spawn to the nearest village, id imagine you could search for the selected biome and spawn at whatever biome you select however forcing a specific biome to spawn at 0,0 would prob require custom worldgen which would likely not play well with any other worldgen mods/datapacks installed

what im saying is it would be a lot easier to search for the biome and move your spawn there than it would be to change the world gen to place the biome where you spawn
