Itemstack required for method


Recommended Posts

So I am attempting to add a right click interaction on my JellyfishEntity that when a bottle is being held it will result in Jellyfish Jelly. I practically just copied the Cow milk interaction and the only issue I am having is that the method requires an ItemStack however I am unsure as how to convert my item registry into that.

This is in the entity:

    public InteractionResult mobInteract(Player p_28298_, InteractionHand p_28299_) {
        ItemStack itemstack = p_28298_.getItemInHand(p_28299_);
        if (itemstack.is(Items.GLASS_BOTTLE) && !this.isBaby()) {
           p_28298_.playSound(SoundEvents.COW_MILK, 1.0F, 1.0F);
           ItemStack itemstack1 = ItemUtils.createFilledResult(itemstack, p_28298_, ModItems.JELLYFISH_JELLY.getDefaultInstance());
           p_28298_.setItemInHand(p_28299_, itemstack1);
           return InteractionResult.sidedSuccess(this.level.isClientSide);
        } else {
           return super.mobInteract(p_28298_, p_28299_);

And this is my Item:

    public static final RegistryObject<Item> JELLYFISH_JELLY = ITEMS.register("jellyfish_jelly", 
        () -> new JellyfishJellyItem(new Item.Properties().craftRemainder(Items.GLASS_BOTTLE).tab(ModCreativeModeTab.GODBOB_TAB)));

The only issue seems to be with the

Thanks in advance.

Your JELLYFISH_JELLY is a RegistryObject<Item> not an Item.

You need to use get() to obtain the real registered object.

If you don't post your logs/debug.log we can't help you. For curseforge you need to enable the forge debug.log in its minecraft settings. You should also post your crash report if you have one.

If there is no error in the log file and you don't have a crash report then post the launcher_log.txt from the minecraft folder. Again for curseforge this will be in your curseforge/minecraft/Install

Large files should be posted to a file sharing site like https://gist.github.com  You should also read the support forum sticky post.
