Trying to use AnvilUpdateEvent

[Thanatos_0173]

I'm trying to use the anvilUpdateEvent, but it's actually doesn't work, and idk why. Could someone help me?

Here is my code:

package com.thanatos0173.magicgems.init;

import com.thanatos0173.magicgems.main;
import net.minecraft.item.ItemStack;
import net.minecraft.item.Items;
import net.minecraftforge.api.distmarker.Dist;
import net.minecraftforge.event.AnvilUpdateEvent;
import net.minecraftforge.eventbus.api.SubscribeEvent;
import net.minecraftforge.fml.common.Mod;



@Mod.EventBusSubscriber(modid = main.MODID, bus = Mod.EventBusSubscriber.Bus.FORGE, value = Dist.CLIENT)
public class ModCrafts {

    @SubscribeEvent
    public static void AnvilCraft(AnvilUpdateEvent anvilUpdateEvent){
        if(anvilUpdateEvent.getLeft().isItemEqual(new ItemStack(Items.ACACIA_BOAT,1)) && anvilUpdateEvent.getRight().isEmpty())

        {
            anvilUpdateEvent.setOutput(new ItemStack(Items.ACACIA_FENCE,1));
        }
    }
}

I do what you say, but nothing changing...

package com.thanatos0173.magicgems.init;

import com.thanatos0173.magicgems.main;
import net.minecraft.item.ItemStack;
import net.minecraft.item.Items;
import net.minecraftforge.api.distmarker.Dist;
import net.minecraftforge.event.AnvilUpdateEvent;
import net.minecraftforge.eventbus.api.SubscribeEvent;
import net.minecraftforge.fml.common.Mod;



@Mod.EventBusSubscriber(modid = main.MODID, bus = Mod.EventBusSubscriber.Bus.FORGE, value = Dist.DEDICATED_SERVER)
public class ModCrafts {

    @SubscribeEvent
    public static void AnvilCraft(AnvilUpdateEvent anvilUpdateEvent){
        if(anvilUpdateEvent.getLeft().isItemEqual(new ItemStack(Items.ACACIA_BOAT,1)) && anvilUpdateEvent.getRight().isItemEqual(new ItemStack(Items.ACACIA_BOAT,1)))

        {
            anvilUpdateEvent.setOutput(new ItemStack(Items.ACACIA_FENCE,1));
        }
    }
}

Can you help me?

 

package com.thanatos0173.magicgems.init;

import com.thanatos0173.magicgems.main;
import net.minecraft.enchantment.Enchantments;
import net.minecraft.item.ItemStack;
import net.minecraft.item.Items;
import net.minecraftforge.event.AnvilUpdateEvent;
import net.minecraftforge.eventbus.api.SubscribeEvent;
import net.minecraftforge.fml.common.Mod;
@Mod.EventBusSubscriber(modid = main.MODID, bus = Mod.EventBusSubscriber.Bus.FORGE)
public class ModCrafts {
    @SubscribeEvent
    public static void AnvilCraft(AnvilUpdateEvent anvilUpdateEvent) {
        ItemStack left = anvilUpdateEvent.getLeft();
        if (left.isItemEqualIgnoreDurability(new ItemStack(Items.NETHERITE_SWORD, 1)) && anvilUpdateEvent.getRight().isItemEqual(new ItemStack(ModItems.poison_gem.get(), 1))) {
            anvilUpdateEvent.setOutput(anvilUpdateEvent.getLeft().copy().addEnchantment(Enchantments.FIRE_ASPECT,2));
            anvilUpdateEvent.setCost(6);
        }
    }
}

use debugger to check this condition, since you other code looks okay.
I would also recommend you to check the Items and not the ItemStacks:

if (left == Items.NETHERITE_SWORD)

I gonna do it, but without adding a enchant, it's work. The problem is that I have an error with the addEnchantement method

define 'problem'

Here it is :

'setOutput(net.minecraft.item.ItemStack)' in 'net.minecraftforge.event.AnvilUpdateEvent' cannot be applied to '(void)'

I was knowing that someone will tell me that, and I know (nearly) what is the error. But, my question is : how can I add an enchantement on the sword if this method can't work ?

Please answer me...

Ok, thanks
