Strange Biome Generation

[DanilaFE]

So I made a custom biome, the most basic one, and tried to make a custom top block.

First I tried with the custom block I made, it crashed. Then I tried with another custom block I made, and it generated a biome full of tripwire hooks. Finally, I tried manually defining the ID and got a biome with a lot of...

Potato crops.

I'm using this.topBlock = (byte)MyMainClass.MyCustomBlock.blockID

Help please!

Are you keeping the block IDs low? I've never had a problem myself, but I've heard that anything over the low 200's or so can cause problems due to being converted to bytes and whatnot.

[DanilaFE]

Eeeeh th ID's are 899+

The question is, am I ALLOWED to use IDs less than 200

And how can I work around that?

[firstdwarf]

The final vanilla ID is 173, for a block of coal. You CAN use any block ID higher than that but before 256, but it may cause conflicts with other mods. Remember, most blocks don't need to be that low! My best idea would be to make only the blocks in the biome that low, and then make sure that you have a config file for those blocks to pick any one of the exceedingly limited number of slots that might be available.

 

On reading up a bit: since biome blocks are stored as bytes, they absolutely must have IDs under 256. Otherwise, they begin to count negative and the kinds of problems you are having start to show up.

 

In summary: Pick an ID between 173 and 256 and make sure it's configurable to resolve conflicts with other mods.

 

Hope that helps!

Alrighty! Thanks for the info!

EDIT

Nope. My block has the Id if 177, and the game crashes, due to a

but I've heard that anything over the low 200's or so

 

256 and up won't work.  Because the vanilla terrain generators deal with block IDs as a byte.

If you post your code, particularly the lines specified in the log, we may be able to help more.

Main Class with unimportant things cropped out:

public static final int FrozenBiomeDirtID = 177;
//Creating the Forge instance
@Instance(value = "FrozenWorld")
public static FrozenWorld instance;

And my BiomeGenFrozen:

 

public BiomeGenFrozen(int id) {
	super(id);
	this.topBlock = (byte)FrozenWorld.FrozenBiomeDirt.blockID; //<——Causes the crash

}

You have two of FMLInitializationEvent. It is highly unlikely going to work.
