I have an AttackEntityEvent and I can't get it to cancel.

public class ModEvents {
    @Mod.EventBusSubscriber(modid = GreekMythsMod.MOD_ID)
    public class ForgeEvents {
        @SubscribeEvent
        public static void onPlayerAttackEntity(AttackEntityEvent event) {
            ItemStack item = event.getEntity().getItemInHand(InteractionHand.MAIN_HAND);
            if (item == new ItemStack(ModItems.CELESTIAL_BRONZE_SWORD.get(), 1) && !(event.getTarget() instanceof Enemy)) {
                event.setCancelled(true);
            }
            
        }
    }
}

It is supposed to check if you are holding a celestial bronze sword and you are not hitting an enemy. It says that AttackEntityEvent is not cancelable.

A workaround I would do for this is to just make the attack do 0 damage.

I don't want to do that because then it would still show an animation.

Also, the only one that sets damage (LivingHurtEvent) doesn't let me get the target.

Not true.

There is zero possiblity the ItemStack in the player's inventory will be referentially equal to a new instance of an ItemStack.

Perhaps you meant?

            if (item.is(ModItems.CELESTIAL_BRONZE_SWORD.get()) && !(event.getTarget() instanceof Enemy)) {

So Gradle stopped throwing errors, maybe I had a typo? Thank you for your help.
