Hello, what state trying to make a 2x1 block and I can't do it, and get to this point but I need to eliminate the two blocks at the same time, can someone help me?

 

public class CustomModeBlock extends HorizontalDirectionalBlock {

//SHAPE

public static final DirectionProperty FACING = HORIZONTAL_FACING;

//NUEVO

public static final BooleanProperty BEING_PLACED = BooleanProperty.create("being_placed" );

//public static final EnumProperty<DoubleBlockHalf> HALF = BlockStateProperties.DOUBLE_BLOCK_HALF;

//LAS PROPIEDADES DEL BLOQUE

public CustomModeBlock(Properties properties) {

super(properties);

}

//FACING

@Override

protected void createBlockStateDefinition(StateDefinition.Builder<Block, BlockState> builder) {

builder.add(HORIZONTAL_FACING);

builder.add(CustomModeBlock.BEING_PLACED);

//builder.add(FACING);

//builder.add(HALF);

}

//NUEVO

@Override

public BlockState getStateForPlacement(BlockPlaceContext pContext) {

Direction direction = pContext.getHorizontalDirection().getOpposite();

BlockPos blockPos = pContext.getClickedPos();

BlockPos blockPos1 = blockPos.relative(direction);

Level level = pContext.getLevel();

return level.getBlockState(blockPos1).canBeReplaced(pContext) && level.getWorldBorder().isWithinBounds(blockPos1) ? this.defaultBlockState().setValue(FACING, direction) : null;

}

@Override

public void setPlacedBy(Level pLevel, BlockPos pPos, BlockState pState, LivingEntity pEntity, ItemStack pStack) {

BlockPos blockPos = pPos.relative(pState.getValue(FACING).getCounterClockWise());

pLevel.setBlock(blockPos, pState, 3);

}

@Override

public boolean canSurvive(BlockState pState, LevelReader pReader, BlockPos pPos) {

if (pState.getValue(BEING_PLACED) == true){

return true;

}

if (pReader.getBlockState(pPos.relative(FACING).getBlock().equals(getStateForPlacement))){

return true;

}

return false;

}

@Override

public BlockState rotate(BlockState pState, Rotation pRotation) {

return pState.setValue(FACING, pRotation.rotate(pState.getValue(FACING)));

}

@Override

public BlockState mirror(BlockState pState, Mirror pMirror) {

return pState.rotate(pMirror.getRotation(pState.getValue(FACING)));

}

//SHAPE

@Override

public VoxelShape getShape(BlockState pState, BlockGetter pLevel, BlockPos pPos, CollisionContext pContext) {

switch (pState.getValue(FACING)){

case NORTH:

return SHAPE_N;

case SOUTH:

return SHAPE_S;

case EAST:

return SHAPE_E;

case WEST:

return SHAPE_W;

default:

return SHAPE_N;

}

}

 

 

 

 

 

 

 

Look at how BedBlock or DoorBlock works. There are also plenty of examples with tall plants for this as well.
