Working with redstone

[Elite_Puddle]

Im trying to create a block that produces power from the north face unless it receives power from the south face, I have managed to create a block that Redstone connects to but Im struggling to progress further, I know the canConnectRedstone() function exists but Im not sure how to work with it.

below is the code i have so far: 

@SubscribeEvent
    public static void onRegisterBlocks(RegistryEvent.Register<Block> event) {
        event.getRegistry().registerAll(
            setup(new Not_Block(Block.Properties.create(Material.ROCK)
            .hardnessAndResistance(3.0F,3.0F).sound(SoundType.STONE))
            , "not_block"));
    }

public class Not_Block extends RedstoneDiodeBlock {

    public static final DirectionProperty FACING = HorizontalBlock.HORIZONTAL_FACING;
    public static final IntegerProperty DELAY = BlockStateProperties.DELAY_1_4;
    public static final BooleanProperty POWERED = BlockStateProperties.POWERED;
    
    public Not_Block(Properties properties) {
        super(properties);
        this.setDefaultState(this.stateContainer.getBaseState().with(FACING, Direction.NORTH));
    }
    
    protected int getDelay(BlockState state) {
          return state.get(DELAY) * 2;
       }
    
    //sets the block to always be placed facing the player
    @Override
    public BlockState getStateForPlacement(BlockItemUseContext context) {
        return this.getDefaultState().with(FACING, context.getPlacementHorizontalFacing().getOpposite());
    }
    
    @Override
    protected void fillStateContainer(Builder<Block, BlockState> builder) {
        builder.add(FACING);
    }
    
}

As an aside, you know that a redstone torch is already a "not block" right?

yes I know, im trying to condense all the logic gates into single blocks and NOT seemed like the easiest to start with

Then I suggest looking at the redstone torch.
