Hi i have this custom item i made is simple, its just one that when u right-click on a mob it shows u his information, but there is two things i still didnt made up.

First.

When i right-click on a mob and the item is used the method is called twice occurring on a print duplication

Second.

I still didnt get  chatFormatting Format that put my text on a column way.

Here i leave my code to get helped, it just a simple one right now.

public class Life_detector extends Item {
    public Life_detector(Properties pProperties) {
        super(pProperties);
    }


    @Override
    public boolean canAttackBlock(BlockState pState, Level pLevel, BlockPos pPos, Player pPlayer) {
        return false;

    }


    @Override
    public InteractionResult interactLivingEntity(ItemStack pStack, Player pPlayer, LivingEntity pInteractionTarget, InteractionHand pUsedHand) {

        if(pStack.getItem()==ModItems.LIFE_CHECKER.get()){

            checkLife(pInteractionTarget,pPlayer);

        }

        return InteractionResult.SUCCESS;
    }

    private void checkLife(LivingEntity livingEntity, Player player){
       if(livingEntity instanceof Mob mob){
        player.sendSystemMessage(Component.literal("Name: "+mob.getName().getString()).withStyle(ChatFormatting.DARK_RED));
       }
    }

    
    public void appendHoverText(ItemStack stack, Level world, List<Component> tooltip, TooltipFlag flag) {
        tooltip.add(Component.literal("Right-click to get the info of a mob").withStyle(ChatFormatting.GOLD));
        super.appendHoverText(stack, world, tooltip, flag);
    }
}

 

In minecraft most callbacks get invoked on both the client and server.

search this forum for InteractionResult.sidedSuccess or look at how one of the vanilla items handles sides.
