Hi, I am trying to register a very simple "Connected Block" block with 4 boolean properties with default state of false for all. On placement, where getStateForPlacement is called, I just want to set the "south_connected" property to true for testing. However, the F3 console displays all 4 properties as true once placed. PS removing the custom implementation of getStateForPlacement returns a block state with all 4 properties as false as expected.

 

public class ConnectedBlock extends Block {
    public static final BooleanProperty SOUTH_CONNECTED = BooleanProperty.create("south_connected");
    public static final BooleanProperty EAST_CONNECTED = BooleanProperty.create("east_connected");
    public static final BooleanProperty WEST_CONNECTED = BooleanProperty.create("west_connected");
    public static final BooleanProperty NORTH_CONNECTED = BooleanProperty.create("north_connected");

    public ConnectedBlock() {
        super(BlockBehaviour.Properties.of(Material.STONE));

        registerDefaultState(stateDefinition.any()
                .setValue(SOUTH_CONNECTED, false)
                .setValue(EAST_CONNECTED, false)
                .setValue(WEST_CONNECTED, false)
                .setValue(NORTH_CONNECTED, false)
        );
    }

    @Override
    public BlockState getStateForPlacement(BlockPlaceContext context) {
        return getStateDefinition().any().setValue(SOUTH_CONNECTED, true);
    }

    @Override
    protected void createBlockStateDefinition(StateDefinition.Builder<Block, BlockState> builder) {
        builder.add(SOUTH_CONNECTED, EAST_CONNECTED, WEST_CONNECTED, NORTH_CONNECTED);
    }
}

Why is that? Thanks in advanced

 return this.defaultBlockState().setValue(SOUTH_CONNECTED, true);

The why is look at Block.getStateForPlacement()

Correct me if I'm wrong. Is ".getStateForPlacement" called to get an appropriate blockstate given some logic when a block is being placed? 

Yes. You might want to look at what FenceBlock does. That sounds close to what you are doing?

Thanks! I managed to fix my problem looking at the fence block.
