The Bug:

minecraft.used:minecraft.goat_horn doesn't increase when using goat horns.

Steps to Reproduce:

• Create a scoreboard objective for tracking the use of a goat horn and set it to display on the sidebar.

• /scoreboard objectives add UseGoatHorn minecraft.used:minecraft.goat_horn

• /scoreboard objectives setdisplay sidebar UseGoatHorn

• Obtain a goat horn and use it.
• Take note as to whether or not minecraft.used:minecraft.goat_horn increases when using goat horns.

Observed Behavior:

The scoreboard doesn't increase.

Expected Behavior:

The scoreboard would increase.

Code Analysis:

Code analysis by Avoma can be found below.

The following is based on a decompiled version of Minecraft 1.19 Pre-release 2 using Mojang mappings.

public class InstrumentItem extends Item {
   ...
   @Override
      public InteractionResultHolder<ItemStack> use(Level level, Player player, InteractionHand interactionHand) {
         ItemStack itemStack = player.getItemInHand(interactionHand);
         Optional<Holder<Instrument>> optional = this.getInstrument(itemStack);
         if (optional.isPresent()) {
            Instrument instrument = optional.get().value();
            player.startUsingItem(interactionHand);
            InstrumentItem.play(level, player, instrument);
            player.getCooldowns().addCooldown(this, instrument.useDuration());
            return InteractionResultHolder.consume(itemStack);
         }
         return InteractionResultHolder.fail(itemStack);
      }
      ...

If we look at the above class, we can see that the awardStat() method (the method responsible for incrementing player statistics) is never called throughout this piece of code, thus making minecraft.used:minecraft.goat_horn not increase when using goat horns.

Fix:

Simply calling the awardStat() method where appropriate within this piece of code will resolve this problem. The following line of code can be used to fix this issue.

player.awardStat(Stats.ITEM_USED.get(this));
