So i have a BlockEntity that's has a container and stores items inside of it, when you click on it, item will render and stored inside of block.

But there's a problem, when i click on it using item like swords or tridents, it doesn't save item tags like durability, enchantments, or names.

I know there's a NBT tags, but i didn't saw vanilla code using this on Item Frame etc. And i think there's some other ways to do that.

 

Here's some code ->

@Override
    public InteractionResult use(BlockState state, Level level, BlockPos pos, Player player, InteractionHand hand, BlockHitResult result) {
        if(!level.isClientSide){
            if (level.getBlockEntity(pos) instanceof SpecialCauldronBlockEntity entity) {
                if (level.getBlockState(pos.below()).is(ModTags.Blocks.SPECIAL_CAULDRON_EXPLODES)) {
                    level.explode(null, DamageSource.MAGIC, null, pos.getX(), pos.getY(), pos.getZ(), 3.5f, false, Explosion.BlockInteraction.DESTROY);
                }
            }
        }

        if (level.isClientSide) {
            if (level.getBlockEntity(pos) instanceof SpecialCauldronBlockEntity entity) {
                if (entity.getItem(0).is(ItemStack.EMPTY.getItem()) && !player.getMainHandItem().is(ItemStack.EMPTY.getItem())) {
                    ItemStack item = player.getItemInHand(hand).copy();
                    level.playLocalSound(pos.getX(), pos.getY(), pos.getZ(), SoundEvents.END_PORTAL_FRAME_FILL, SoundSource.BLOCKS, 1.0f, 1.0f, true);
                    entity.setItem(0, item);
                    player.getMainHandItem().shrink(1);
                } else {
                    if (!entity.getItem(0).is(ItemStack.EMPTY.getItem())) {
                        player.addItem(entity.getItem(0).getItem().getDefaultInstance());
                        level.playLocalSound(pos.getX(), pos.getY(), pos.getZ(), SoundEvents.ITEM_PICKUP, SoundSource.BLOCKS, 0.75f, 1f, true);
                        entity.setItem(0, ItemStack.EMPTY);
                    }
                }
            }
        }
        return InteractionResult.SUCCESS;
    }

 

(It started working by itself idk why). But i still interested how to do it properly.

And i also got another problem, when i'm clicking my block with sword, it work's but when i'm trying to break it, it doesn't.

Probably because of my block thinks that i have a sword in my hand (because you cant break block with hand) but it's not.

 

Updated Code ->

@Override
    public InteractionResult use(BlockState state, Level level, BlockPos pos, Player player, InteractionHand hand, BlockHitResult result) {
        if(!level.isClientSide){
            if (level.getBlockEntity(pos) instanceof SpecialCauldronBlockEntity entity) {
                if (level.getBlockState(pos.below()).is(ModTags.Blocks.SPECIAL_CAULDRON_EXPLODES)) {
                    level.explode(null, DamageSource.MAGIC, null, pos.getX(), pos.getY(), pos.getZ(), 3.5f, false, Explosion.BlockInteraction.DESTROY);
                }
            }
        }

        if (level.isClientSide) {
            if (level.getBlockEntity(pos) instanceof SpecialCauldronBlockEntity entity) {
                if (entity.getItem(0).is(ItemStack.EMPTY.getItem()) && !player.getMainHandItem().is(ItemStack.EMPTY.getItem())) {
                    ItemStack item = player.getItemInHand(hand).copy();
                    level.playLocalSound(pos.getX(), pos.getY(), pos.getZ(), SoundEvents.END_PORTAL_FRAME_FILL, SoundSource.BLOCKS, 1.0f, 1.0f, true);
                    entity.setItem(0, item);
                    player.getMainHandItem().shrink(1);
                } else {
                    if (!entity.getItem(0).is(ItemStack.EMPTY.getItem())) {
                        player.addItem(entity.getItem(0));
                        level.playLocalSound(pos.getX(), pos.getY(), pos.getZ(), SoundEvents.ITEM_PICKUP, SoundSource.BLOCKS, 0.75f, 1f, true);
                        entity.setItem(0, ItemStack.EMPTY);
                    }
                }
            }
        }
        return InteractionResult.SUCCESS;
    }

I got it, it happened because it was executed on wrong side, block container works fine, but how do i render items?

Nevermind, fixed this.

Updated code ->

@Override
    public InteractionResult use(BlockState state, Level level, BlockPos pos, Player player, InteractionHand hand, BlockHitResult result) {
        // Explode if placed on not correct block


        if (!level.isClientSide){
            if (level.getBlockEntity(pos) instanceof SpecialCauldronBlockEntity entity) {
                if (level.getBlockState(pos.below()).is(ModTags.Blocks.SPECIAL_CAULDRON_EXPLODES)) {
                    level.explode(null, DamageSource.MAGIC, null, pos.getX(), pos.getY(), pos.getZ(), 3.5f, false, Explosion.BlockInteraction.DESTROY);
                }
            }
        }

        // Interaction - Server Side
        if (!level.isClientSide) {
            if (level.getBlockEntity(pos) instanceof SpecialCauldronBlockEntity entity) {
                if (entity.getItem(0).is(ItemStack.EMPTY.getItem()) && !player.getMainHandItem().is(ItemStack.EMPTY.getItem())) {
                    ItemStack item = player.getItemInHand(hand).copy();
                    entity.setItem(0, item);
                    player.getMainHandItem().shrink(1); // TODO Make normal shrink
                } else {
                    if (!entity.getItem(0).is(ItemStack.EMPTY.getItem())) {
                        player.addItem(entity.getItem(0));
                        entity.setItem(0, ItemStack.EMPTY);
                    }
                }
            }
        }

        // Interaction - Client Side
        if (level.isClientSide) {
            if (level.getBlockEntity(pos) instanceof SpecialCauldronBlockEntity entity) {
                if (entity.getItem(0).is(ItemStack.EMPTY.getItem()) && !player.getMainHandItem().is(ItemStack.EMPTY.getItem())) {
                    ItemStack item = player.getItemInHand(hand).copy();
                    level.playLocalSound(pos.getX(), pos.getY(), pos.getZ(), SoundEvents.END_PORTAL_FRAME_FILL, SoundSource.BLOCKS, 1.0f, 1.0f, true);
                    entity.setItem(0, item);
                } else {
                    if (!entity.getItem(0).is(ItemStack.EMPTY.getItem())) {
                        level.playLocalSound(pos.getX(), pos.getY(), pos.getZ(), SoundEvents.ITEM_PICKUP, SoundSource.BLOCKS, 0.75f, 1f, true);
                        entity.setItem(0, ItemStack.EMPTY);
                    }
                }
            }
        }
        return InteractionResult.SUCCESS;
    }

 

Might be useful.
