the error message

 

and here what i use in my biomecode

 

 

public BiomeGenAitherMountain(int par1)

    {

        super(par1);

        this.spawnableCreatureList.clear();

        this.fillerBlock = (byte) Server.AitherDirt.blockID;

this.theBiomeDecorator.grassPerChunk = 12;

        this.waterColorMultiplier = 500069595;

  }

First of all, study Your Ecplipse Console Output carefully to get what line causes the error - I cannot tell which line of Your code does it, as the code You've posted doesn't have line numbers.

 

This could be

 

this.spawnableCreatureList.clear();

if spawnableCreatureList is null, this will cause problem.

this.fillerBlock = (byte) Server.AitherDirt.blockID;

if Server or AitherDirt is null, this will cause problem

this.theBiomeDecorator.grassPerChunk = 12;

if theBiomeDecorator is null, this will cause problem.

 

Every one of these fields needs to be initialized before You reference them - check which one of them isn't initialized before public BiomeGenAitherMountain is called and initialize it, with any values - this will fix Your problem.

what do you mean with null ?

I now remove this.spawnableCreatureList.clear(); and this.theBiomeDecorator.grassPerChunk = 12; (the last one because it´s not really  necessary

 

Is this entry right in Server.class 

 

    public final static Block_AitherDirt AitherDirt = new Block_AitherDirt();

 

    GameRegistry.registerBlock(AitherDirt);

 

What i have to change?

 

 

Edit: Ok i have it know. It was so simple the whole time ._.

 

Edit again: Now it won´t let me load a world

The block you put in filler or top block has to be an ID below 256 or else you will crash when generating

[Mazetar]

what do you mean with null ?

 

Null is a basic programming term which you must look up and understand as its a common problem! Null is a value or well rather the lack of one, it's NOT to be confused with 0!

 

Check it out on the web

Could you elaborate? What is your source for saying this, as to me this sounds wrong I would like to know why it wouldnt handle block ids above 256?

[microjunk]

this has been discussed many times on the MinecraftForums....and the fact that (byte) is a reference of 256, it would stand to reason that block ids must be below 256 in order to be a top and filler block in the biome. I have done this, as has -reaper- and several others on the MCF. I have tested the theory manytimes and it only works when the block id is below that mark, it can be done, just mind your block ids, they are getting fewer and fewer with each MC update. It is hard coded in the MC code and can not be changed with out a custom way of doing it, and I have no idea how this would be done. Either way, for now, your block id must be below 256, and initialized before the biome you are trying to use the block in.....good luck and I hope it works out.

As previous poster stated the filler and top blocks are Byte variables not integers, and the highest number block ID is 256 that will work with the terrain gen.

Right, Java starts  at 0, my bad
