[1.16.5] Help with custom Glass Block

[Luis_ST]

I want to creat a block wich is translucent but disable sky light through the block

i just creat this:

but when i stand in a cube of my glass there is a skylight:

Override the getOpacity in your glass block class, look at the super method implementation to see how opacity is normally handled. It should be pretty easy to see what to put in your override

i just looked at it but is this not controlled by method propagatesSkylightDown beacause:

and it dosent work.

   @Deprecated
   public int getOpacity(BlockState state, IBlockReader worldIn, BlockPos pos) {
      if (state.isOpaqueCube(worldIn, pos)) {
         return worldIn.getMaxLightLevel();
      } else {
         return state.propagatesSkylightDown(worldIn, pos) ? 0 : 1;
      }
   }

this is currently my block class:

You do know what that returned int does, right?

I think yes the int returned is the light going through the block

so 0 will retrun no light through the block

or is that wrong?

Lets check the original function.

"If the block is opaque, return the maximum light value. Otherwise if sky light is supposed to propagate downwards, return 0. Otherwise return 1."

 

🤔

okay i understand but

if i understand this correctly i have to return 0.

 

but when i set the value to 0 it dosent work and when i set it to 1 (for testing) it also dosent work

"supposed to propagate downwards" -> lets sky light through it.

This is clearly not the effect you want. The point wasn't to follow the existing logic to see what the default method returns for your block (because duh, the default logic doesn't work for you), it was to figure out how opaque blocks block skylight.

So if 0 is the wrong effect and then i have to use 1 but why it dosent work

	}

}

THERE ARE MORE VALUES THAN 0 AND 1. I even told you, twice, what to look at.

 

Here's a big blindingly stupid hint:

The value returned from getOpacity is subtracted off the current light value in order to determine how bright the next space is.

Thanks now it work (sometimes im a bit lost when it comes to understanding things)
