I have a log block with metadata, and what Im trying to do is make the block with the meta "1" to give of light. I just can't seem to do this. I have tried: (which probably is totally wrong)

 

In my log class:

 

if(new ItemStack(Item.getItemFromBlock(this).getItemDamage() == 1) {

setLightLevel(3.0F);

}

 

I don't know if that's wrong or something but it keeps crashing on startup

That is completely wrong.

1. A new ItemStack instance always has metadata of 0, unless you set it to another value

2. setLightLevel sets the light level for the block instance, regardless of metadata.

 

You need to override

getLightValue(world, x, y, z)

in your log block class and get it's metadata by calling world#getBlockMetadata(x, y, z) [which returns the metadata] and check if the metadata is the desired one.

A side note: If you can place your log in different directions like the vanilla ones, you actually need to strip the metadata from it's direction value with bitwise operations.

Thnx!
