[1.12.2] Setting light level of Block for meta/blockstate

[Meldexun]

Is it possible to set the light level of my block to for example 5 for a meta value or for an blockstate property?

Thank you! I just searched for a getLightLevel method and didn't found it...

Block#getLightValue(IBlockState)

Use your IDE to find it.

Override Block#getLightValue.

The problem is that i want that block to be generated but then it is not glowing at all.

getLightValue in my Block class:

	@Override
	public int getLightValue(IBlockState state, IBlockAccess world, BlockPos pos) {
		return state.getValue(SEED) == 3 ? 30 : state.getValue(SEED) == 2 ? 20 : 0;
	}

and the way my block is generated:

public class WorldGeneratorKelp extends WorldGenerator {
	
	@Override
	public boolean generate(World worldIn, Random rand, BlockPos position) {
		worldIn.setBlockState(position.up(kelpHeight + 10), InitBlock.CREEPVINE.getStateFromMeta(rand.nextInt(1) + 2), 3);
		return true;
	}

 

But when i use /setblock x y z better_diving:creepvine 3 then it is glowing.

It's probably because the maximum light level is 15 and i tried to set it to 30(20).
