I am trying to render the portal particle effect on an item in a players hand. I've gotten as far as the particles spawning in the world when the item is in the players hand. The only issue I am having is I do not know how to properly pass the player position. Since the onUpdate() for items has an Entity parameter I tried messing with that a bit doing a entity.PlayerLocation but during log testing it just returned null.

Here is what I've done so far with the method:

@Override
    @SideOnly(Side.CLIENT)
    public void onUpdate(ItemStack itemStack, World world, Entity entity, int par4, boolean inHand){
        if(entity instanceof EntityPlayer && inHand){
            
            for(int i = 0; i < 4; i++){
                float particleX = 660 + random.nextFloat();//Right now I have hard coded coordinates for testing and will switch out for proper positioning  
                float particleY = 5 + random.nextFloat();
                float particleZ = 340 + random.nextFloat();

                float particleMotionX = -0.5F + random.nextFloat();
                float particleMotionY = -0.5F + random.nextFloat();
                float particleMotionZ = -0.5F + random.nextFloat();

                world.spawnParticle("portal", particleX, particleY, particleZ, particleMotionX, particleMotionY, particleMotionZ);
            }
        }
    }

entity.posX, entity.posY, entity.posZ?
