Grape Block

Code

public class GrapesBlock extends CustomBlock {

    public static BooleanProperty BERRIES;

    static {
        BERRIES = Properties.BERRIES;
    }

    public GrapesBlock(BlockSettings settings) {
        super(settings, 4, new ItemBuilder(Material.EMERALD).setCustomModelData(4).setDisplayName("§r§6" + settings.getName()).build());
        setDefaultState(getDefaultState().with(BERRIES, false));
    }

    @Override
    public void appendProperties(PropertyListBuilder propertyListBuilder) {
        propertyListBuilder.add(BERRIES);
    }

    @Override
    public CustomBlockState getPlacementState(ItemPlacementContext ctx) {
        return getDefaultState().with(BERRIES, true);
    }

    @Override
    public ActionResult onUse(CustomBlockState state, World world, Location location, Player player, EquipmentSlot hand) {
        if (state.get(BERRIES) == false) {
            return ActionResult.SUCCESS;
        }
        state.with(BERRIES, false);
        state.update();

        //DropItem
        ItemStack stack = new ItemStack(Material.SWEET_BERRIES);
        stack.setAmount(blockRandom.nextInt(2) + 1);
        world.dropItem(location.add(settings.getWidth() / 2, 0, settings.getWidth() / 2), stack);

        //Regrow
        new BukkitRunnable() {

            @Override
            public void run() {
                state.with(BERRIES, true);
                state.update();
            }
        }.runTaskLater(CustomBlocksApiPlugin.getInstance(), blockRandom.nextInt(60) + 200);

        return ActionResult.SUCCESS;
    }

    @Override
    public void applyInitialModelTransformations(ItemDisplay display) {
        display.setRotation(blockRandom.nextInt(360), 0);
    }

    @Override
    public CMDLookupTable createCMDLookupTable(CMDLookupTableBuilder tableBuilder) {
        return tableBuilder.with(BERRIES, false).hasCustomModelData(5).addElement()
                .with(BERRIES, true).hasCustomModelData(4).addElement().build();
    }
}

Animated Computer Block

Code

public class AnimatedComputerBlock extends SimpleAnimatedBlock {

    private static BooleanProperty ENABLED;

    static {
        ENABLED = Properties.ENABLED;
    }

    public AnimatedComputerBlock(BlockSettings settings) {
        super(settings, new ItemBuilder(Material.DIAMOND).setCustomModelData(6).setDisplayName("§r§6" + settings.getName()).build(), 10, 7, 6);
        setDefaultState(getDefaultState().with(ENABLED, false));
    }

    @Override
    public void appendProperties(PropertyListBuilder propertyListBuilder) {
        propertyListBuilder.add(ENABLED);
    }

    @Override
    public void onNeighborUpdate(CustomBlockState state, World world, Location location, CustomBlock block, Location fromPos) {
        state.with(ENABLED, location.getBlock().getBlockPower() > 0);
        state.update();
    }

    @Override
    protected boolean shouldPlayFrames(TickState state) {
        return state.getCustomBlockState().get(ENABLED);
    }
}
