Whenever I run my mod it crashes and points to the line of code:

 

 

EntityRegistry.addSpawn(EntityAncientzombie.class, 5, 1, 3, EnumCreatureType.monster, BiomeGenBase.biomeList);

 

 

I have added a mob to the game and this is it's spawn method

I don't know how to fix it :(

Changing 

EntityRegistry.addSpawn(EntityAncientzombie.class, 5, 1, 3, EnumCreatureType.monster, BiomeGenBase.biomelist);

to

EntityRegistry.addSpawn(EntityAncientzombie.class, 5, 1, 3, EnumCreatureType.monster, BiomeGenBase.desert);

fixes the problem, but i want it to be able to spawn in all biomes, except the nether or end

Fixed it by using

                    EntityRegistry

                .addSpawn(EntityAncientzombie.class, 5, 1, 3, EnumCreatureType.monster, BiomeGenBase.BIOMENAME);

for each biome, tedious but works

You can also use this code to make sure you really catch every biome (even modded ones)

	ArrayList<BiomeGenBase> biomes = new ArrayList<BiomeGenBase>();
	for( BiomeGenBase biome : BiomeGenBase.biomeList ) {
		if( biome != null ) {
			biomes.add(biome);
		}
	}
	EntityRegistry.addSpawn(EntityAncientzombie.class, 5, 1, 3, EnumCreatureType.monster, biomes.toArray(BiomeGenBase.biomeList));

This thread makes me sad because people just post copy-paste-ready code when it's obvious that the OP has little to no programming experience. This is not how learning works.

Or, for the really fancy people:

 

BiomeGenBase allBiomes = Iterators.toArray(Iterators.filter(Iterators.forArray(BiomeGenBase.biomeslist), Predicates.notNull()), BiomeGenBase.class);

 

Guava & Functional Programming ftw!

 

oh, you can use Predicates with Guava? Good to know :D

If you are on 1.7.2 then here is what I do:

BiomeGenBase[] allBiomes = Iterators.toArray(Iterators.filter(Iterators.forArray(BiomeGenBase.getBiomeGenArray()),
			Predicates.notNull()), BiomeGenBase.class);

Why?

The solution was already provided previously, what's different in your code?

Let me dig it up, since it shows in search, so someone might want to use it.

 

I'm coding for 1.7.10 and BiomeGenBase.biomesList is not availble directly, there is a method .getBiomeGenArray() that returns it.

 

Also EntityRegistry.addSpawn() wants BiomeGenBase[] as param, not ArrayList<BiomeGenBase>

 

I did it like that :

ArrayList<BiomeGenBase> all_biomesList = new ArrayList<BiomeGenBase>();
	for( BiomeGenBase biome : BiomeGenBase.getBiomeGenArray() ) {
		if( biome != null ) {
			all_biomesList.add(biome);
		}
	}
	BiomeGenBase[] all_biomes_array = new BiomeGenBase[all_biomesList.size()]; // type casting from List to array and stuff
	this.all_biomes = all_biomesList.toArray(all_biomes_array);
