I am trying to make my inventoryTick damage all entities in a 5 block radius constantly and apply particles but the damage is not working. Does anyone know how to make this work? 

public class ElectricPowerCharm extends Item {

    public ElectricPowerCharm(Properties properties) {
        super(properties);
    }

    private int delay = 200;
    private int range = 5; // Range in blocks
    private float damageAmount = 2.0f; // Amount of damage to apply per tick

    @Override
    public void inventoryTick(ItemStack stack, Level level, Entity entity, int itemSlot, boolean isSelected) {
        if (level.isClientSide && entity instanceof Player) {
            Player player = (Player) entity;

            double posX = player.getX();
            double posY = player.getY() + 1.0; // Offset particles slightly above the player's head
            double posZ = player.getZ();

            AABB aabb = new AABB(posX - range, posY - range, posZ - range, posX + range, posY + range, posZ + range);
            for (Entity targetEntity : level.getEntities(player, aabb)) {
                if (targetEntity instanceof LivingEntity) {
                    LivingEntity livingEntity = (LivingEntity) targetEntity;
                    double entityX = livingEntity.getX();
                    double entityY = livingEntity.getY() + 0.7d;
                    double entityZ = livingEntity.getZ();

                    for (int i = 1; i <= 50; i++) {
                        double motionX = level.random.nextGaussian() + 1d;
                        double motionY = level.random.nextGaussian() + 1d;
                        double motionZ = level.random.nextGaussian() + 1d;
                        level.addParticle(ParticleTypes.ELECTRIC_SPARK, entityX, entityY, entityZ, motionX, motionY, motionZ);
                    }

                        livingEntity.hurt(DamageSource.playerAttack(player), damageAmount); // Apply damage
                }
            }
        }
        super.inventoryTick(stack, level, entity, itemSlot, isSelected);
    }
}

Damage is applied on the server. Apply damage on the server and then use #sendParticles to render it on the client.

You shouldn't do this btw since there will only be one instance of your item, so these values will be shared across all unless you register a new item.

wait do u want me to make a packet...

I didn't say that. I said check if the level is on the server, then call #sendParticles to have the particles appear on the client. #sendParticles already sends a packet containing the particles to the necessary client.
