Help saving item data

Posted October 18, 20222 yr

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;
    }

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;

How do I remove 3d headlayer on NPC's skin in CustomNpc? (1.16.5)

I do have to add that this is my answer for 1.12.2 but it should ALSO work for future versions.

How do I remove 3d headlayer on NPC's skin in CustomNpc? (1.16.5)

I know this was posted almost 3 years ago but this is for anyone who is still looking for an answer.

First, find your config folder. -> C:\Users\ (desktop user's name) \curseforge(or the application where you've downloaded you mod)\minecraft\Instances\config (The config folder should be in the same folder as your mods folder.) Once you click on the config folder, search for CustomNpcs.cfg. Once found, click on it (you can edit it using notepad) and search for the line "headweartype". Set the value to 0 if you want a 2d head layer, set it to 1 for a 3d head layer. Then save the options and you should be good to go from there! :)

[1.21.3] How to add effects to food?

game changed the way you create foods.
for example minecraft 1.21.8 code for the golden apple is

Foods.java
public static final FoodProperties GOLDEN_APPLE = new FoodProperties.Builder().nutrition(4).saturationModifier(1.2F).alwaysEdible().build();

Items.java
public static final Item GOLDEN_APPLE = registerItem("golden_apple", new Item.Properties().food(Foods.GOLDEN_APPLE, Consumables.GOLDEN_APPLE));

Consumables.java
public static final Consumable GOLDEN_APPLE = defaultFood() .onConsume( new ApplyStatusEffectsConsumeEffect( List.of(new MobEffectInstance(MobEffects.REGENERATION, 100, 1), new MobEffectInstance(MobEffects.ABSORPTION, 2400, 0)) ) )
