Exception loading block with property

[Ideki]

Hello,

I am trying to create a block that will trigger a redstone power for 10~15 seconds after being right-clicked with a specific item.

I can render the block when if has no functions/property.

But when I try to add a 'is_activating' property, the game crash on load with the following exception:

Quote

[11:37:00] [Render thread/ERROR] [ne.mi.fm.ja.FMLModContainer/]: Exception caught during firing event: Cannot set property BooleanProperty{name=is_activating, clazz=class java.lang.Boolean, values=[true, false]} as it does not exist in Block{null}

This is my block code (I copied the functions from the Lever class):

public class ActivatorBlock extends HorizontalDirectionalBlock {
    public static final BooleanProperty IS_ACTIVATING = BooleanProperty.create("is_activating");

    public ActivatorBlock(Properties properties) {
        super(properties);
        registerDefaultState(defaultBlockState().setValue(FACING, Direction.NORTH).setValue(IS_ACTIVATING, Boolean.valueOf(false)));
    }

    @Override
    protected void createBlockStateDefinition(StateDefinition.Builder<Block, BlockState> builder) {
        super.createBlockStateDefinition(builder);
        builder.add(FACING);
    }

    @Override
    public BlockState getStateForPlacement(BlockPlaceContext context) {
        return defaultBlockState().setValue(FACING, context.getHorizontalDirection().getOpposite());
    }

    @Override
    public InteractionResult use(BlockState blockState, Level level, BlockPos blockPos, Player player, InteractionHand interactionHand, BlockHitResult blockHitResult) {
        if (level.isClientSide) {
            BlockState blockstate1 = blockState.cycle(IS_ACTIVATING);

            return InteractionResult.SUCCESS;
        } else {
            BlockState blockstate = this.pull(blockState, level, blockPos);
            float f = blockstate.getValue(IS_ACTIVATING) ? 0.6F : 0.5F;
            level.playSound((Player)null, blockPos, SoundEvents.LEVER_CLICK, SoundSource.BLOCKS, 0.3F, f);
            level.gameEvent(player, blockstate.getValue(IS_ACTIVATING) ? GameEvent.BLOCK_SWITCH : GameEvent.BLOCK_UNSWITCH, blockPos);
            return InteractionResult.CONSUME;
        }
    }

    public BlockState pull(BlockState p_54677_, Level p_54678_, BlockPos p_54679_) {
        p_54677_ = p_54677_.cycle(IS_ACTIVATING);
        p_54678_.setBlock(p_54679_, p_54677_, 3);
        this.updateNeighbours(p_54677_, p_54678_, p_54679_);
        return p_54677_;
    }

    public int getSignal(BlockState p_54635_, BlockGetter p_54636_, BlockPos p_54637_, Direction p_54638_) {
        return p_54635_.getValue(IS_ACTIVATING) ? 15 : 0;
    }

    public int getDirectSignal(BlockState p_54670_, BlockGetter p_54671_, BlockPos p_54672_, Direction p_54673_) {
        return p_54670_.getValue(IS_ACTIVATING) ? 15 : 0;
    }

    public boolean isSignalSource(BlockState p_54675_) {
        return true;
    }

    private void updateNeighbours(BlockState p_54681_, Level p_54682_, BlockPos p_54683_) {
        p_54682_.updateNeighborsAt(p_54683_, this);
        //p_54682_.updateNeighborsAt(p_54683_.relative(getConnectedDirection(p_54681_).getOpposite()), this);
    }
}

The block is registered as:

    public static final BlockBehaviour.Properties TEST_BLOCK_PROPERTIES = BlockBehaviour.Properties
            .of(Material.GLASS, MaterialColor.TERRACOTTA_BLACK)
            .strength(-1.0F, 3600000.0F)
            .noDrops()
            .sound(SoundType.METAL);

    public static final RegistryObject<Block> ACTIVATOR_BLOCK = BLOCKS.register("activator_block", () -> new ActivatorBlock(TEST_BLOCK_PROPERTIES));

It is always the most obvious things that escape us the most.

Thanks a lot
