I am making a Glass Block and when you look at the block you can see through the world and through blocks around it. Does anyone know how to fix this?

 

Here's my Block class:

public class CoolGlass extends GlassBlock {
    public CoolGlass(Properties properties) {
        super(properties);
    }

    @Override
    public boolean isSideInvisible(BlockState state, BlockState adjacentBlockState, Direction side) {
        if (adjacentBlockState.getBlock() instanceof CoolGlass) {
            if (adjacentBlockState.getRenderType() == state.getRenderType()) {
                return true;
            }
        }

        return super.isSideInvisible(state, adjacentBlockState, side);
    }

    @Override
    public int getOpacity(BlockState state, IBlockReader world, BlockPos pos) {
        return world.getMaxLightLevel();
    }
}

Thanks in advance!

I had the same problem you have to add to the block properties

.notSolid()

i Think this will fix the problem
