IDE gives error, but I don't know how to fix it.

I have made an item that adds a sphere of particles  around a player, but my IDE gives an error at the addParticle. Does someone know what the problem is? This is the code btw.

package com.kuikenpower.falidsmp.init.item;

import com.kuikenpower.falidsmp.particle.ModParticles;

import net.minecraft.client.particle.Particle;
import net.minecraft.core.Position;
import net.minecraft.core.particles.ParticleOptions;
import net.minecraft.core.particles.ParticleTypes;
import net.minecraft.world.InteractionHand;
import net.minecraft.world.InteractionResultHolder;
import net.minecraft.world.effect.MobEffectInstance;
import net.minecraft.world.effect.MobEffects;
import net.minecraft.world.entity.Entity;
import net.minecraft.world.entity.player.Player;
import net.minecraft.world.item.AxeItem;
import net.minecraft.world.item.ItemStack;
import net.minecraft.world.item.Tier;
import net.minecraft.world.level.Level;
import net.minecraft.world.phys.Vec3;

public class jungleDagger extends AxeItem{

	public jungleDagger(Tier p_40521_, float p_40522_, float p_40523_, Properties p_40524_) {
		super(p_40521_, p_40522_, p_40523_, p_40524_);
		// TODO Auto-generated constructor stub
	}

	@Override
    public void inventoryTick(ItemStack p_41404_, Level p_41405_, Entity entity, int p_41407_, boolean p_41408_) {
        Player player = (Player)entity;
        if(player.getMainHandItem().getItem() instanceof SandSword) {
        	player.addEffect(new MobEffectInstance(MobEffects.MOVEMENT_SPEED, 20));
        }
	}
	
	@Override
	public InteractionResultHolder<ItemStack> use(Level world, Player p_41433_, InteractionHand p_41434_) {
		Position location = p_41433_.getPosition(1);
		for (double i = 0; i <= Math.PI; i += Math.PI / 10) {
			   double radius = Math.sin(i);
			   double y = Math.cos(i);
			   for (double a = 0; a < Math.PI * 2; a+= Math.PI / 10) {
			      double x = Math.cos(a) * radius;
			      double z = Math.sin(a) * radius;
			      ((Vec3) location).add(x, y, z);
			      world.addParticle(ParticleTypes.LARGE_SMOKE, location);
			      ((Vec3) location).subtract(x, y, z);
			      
			   }
			}
		return super.use(world, p_41433_, p_41434_);
	}
	
}
