addspawn method crashes game!?!

[FieldGeneral]

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

 

  Reveal hidden contents

 

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

[FieldGeneral]

Any idea on how i would fix this

[FieldGeneral]

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

 

 

[FieldGeneral]

Fixed it by using

                    EntityRegistry

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

for each biome, tedious but works

[SanAndreaP]

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));

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

[crackedEgg]

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);

[The_SlayerMC]

public static BiomeGenBase[] biomes = new BiomeGenBase[]{BiomeGenBase.plains, BiomeGenBase.extremeHills, BiomeGenBase.beach, BiomeGenBase.desert,

BiomeGenBase.desertHills, BiomeGenBase.extremeHillsEdge, BiomeGenBase.forest, BiomeGenBase.forestHills, BiomeGenBase.icePlains, BiomeGenBase.iceMountains, BiomeGenBase.river,

BiomeGenBase.birchForest, BiomeGenBase.birchForestHills, BiomeGenBase.coldBeach, BiomeGenBase.coldTaiga, BiomeGenBase.coldTaigaHills, BiomeGenBase.deepOcean,

BiomeGenBase.extremeHillsPlus, BiomeGenBase.jungleEdge, BiomeGenBase.megaTaiga, BiomeGenBase.megaTaigaHills, BiomeGenBase.mesa, BiomeGenBase.mesaPlateau, BiomeGenBase.mesaPlateau_F, BiomeGenBase.roofedForest, BiomeGenBase.savanna, BiomeGenBase.savannaPlateau, BiomeGenBase.stoneBeach};

 

EntityRegistry.addSpawn(mob.class, group, min, max, type, biomes);

EntityRegistry.addSpawn(mob.class, group, min, max, type, biomes);

 

Why?

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

[AlekBardzo]

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);
