Minecraft 1.21.4 Sword mace mod

[Kageyori]

Description

Hi, I'm trying to make a mod, where when you fall with a sword in your hand and a mace in your hotbar, the sword acts like the mace with all encantments. I'm currently having issues with the reading of the enchantements from the mace and sword, when i run the code i get the following error:

error: cannot find symbol
return stack.getEnchantments().stream()
^
symbol: method stream()
location: class ItemEnchantmentsComponent

I'm programming for version 1.21.4 with JDK 21,
this is the code i made with ChatGPT because i am a beginner pls help:

Java code:
package net.kageyori.swordmacemod;

import com.mojang.serialization.MapCodec;
import net.fabricmc.api.ModInitializer;
import net.fabricmc.fabric.api.event.player.AttackEntityCallback;
import net.minecraft.enchantment.Enchantment;
import net.minecraft.registry.RegistryKey;
import net.minecraft.registry.RegistryKeys;
import net.minecraft.entity.LivingEntity;
import net.minecraft.entity.player.PlayerEntity;
import net.minecraft.item.ItemStack;
import net.minecraft.util.ActionResult;
import net.minecraft.util.Hand;
import net.minecraft.util.hit.EntityHitResult;
import net.minecraft.world.World;

import java.util.Map;

public class SwordMaceMod implements ModInitializer {
@OverRide
public void onInitialize() {
AttackEntityCallback.EVENT.register(this::onAttack);
}

private ActionResult onAttack(PlayerEntity player, World world, Hand hand, net.minecraft.entity.Entity entity, EntityHitResult hitResult) {
	if (world.isClient) return ActionResult.PASS;

	ItemStack mainHandItem = player.getMainHandStack();
	ItemStack mace = getMaceFromHotbar(player);

	// Check if player is falling and has a mace in hotbar
	if (player.fallDistance > 1.5f && isSword(mainHandItem) && mace != null) {
		triggerCombinedMaceSwordEffect(player, mainHandItem, mace, hitResult);
	}
	return ActionResult.PASS;
}

private boolean isSword(ItemStack item) {
	return item.getItem().toString().contains("sword");
}

private ItemStack getMaceFromHotbar(PlayerEntity player) {
	for (ItemStack stack : player.getInventory().main) {
		if (stack.getItem().toString().contains("mace")) {
			return stack;
		}
	}
	return null;
}

private int getEnchantmentLevel(ItemStack stack, Enchantment enchantment) {
	return stack.getEnchantments().stream()
			.filter(nbt -> RegistryKey.of(RegistryKeys.ENCHANTMENT, enchantment.getId()).getValue().equals(enchantment.getId()))
			.map(nbt -> nbt.getInt("lvl"))
			.findFirst()
			.orElse(0);
}

private void triggerCombinedMaceSwordEffect(PlayerEntity player, ItemStack sword, ItemStack mace, EntityHitResult hitResult) {
	if (hitResult.getEntity() instanceof LivingEntity target) {
		float baseDamage = 10.0f; // Default mace damage
		float swordBonus = getEnchantmentLevel(sword, net.minecraft.enchantment.Enchantments.SHARPNESS) * 1.5f;
		float maceBonus = getEnchantmentLevel(mace, net.minecraft.enchantment.Enchantments.SHARPNESS) * 1.5f;
		float totalDamage = baseDamage + swordBonus + maceBonus;

		target.damage(player.getDamageSources().playerAttack(player), totalDamage);
	}
}

}
