(SOLVED) [1.14.4] Modify Vanilla Mob Spawning

[MineModder2000]

for (Biome biome : ForgeRegistries.BIOMES) {
  
  biome.getSpawns(EntityClassification.CREATURE).clear();
  biome.getSpawns(EntityClassification.CREATURE).add(new Biome.SpawnListEntry(EntityType.PIG, 1, 3, 5)); 
}

 

I can clear all existing spawns from a biome using the clear method, which allows me to add a spawn exactly how I want, but then everything is gone. There are remove methods but they don't seem to be able to remove specific entities. Anyone know how to do this?

Why not? Show what you tried.

 

			biome.getSpawns(EntityClassification.CREATURE).remove(EntityType.PIG);

Biome#getSpawns returns a List<Biome.SpawnListEntry>.

Removing "hello" from List(1, 2, 3) is still List(1, 2, 3).

Yeah I had figured that out. I also just figured out how to remove the specific entity from the index ?

Indices? This is 2020. Use removeIf with a Predicate to tell the list which elements you want removed.

I'm old school, but I guess I can learn new tricks ?

 

PS : I just learned how to do it.

I'm very new to modding and I can't seem to figure out how to do it...

Maybe I'm being really stupid, but how did you do it?

Iterator<SpawnListEntry> biomeSpawns = biome.getSpawns(EntityClassification.CREATURE).iterator();
    			
while(biomeSpawns.hasNext()) {
	SpawnListEntry entry = biomeSpawns.next();
	if (entry.entityType == EntityType.PIG)
	{
		biomeSpawns.remove();
	}
}

 

Thank you! I will definitely look at that.  I did get it to work eventually. Don't know if it looks bad though...

Ahhh okay, Thank you very much for your help!
