How to make a procedure when you eat a food, it teleport the player to a random location, similar to a chorus fruit

maybe the /spreadplayers command (I think that's what it is)

I found the code chorus fruit uses:

   public ItemStack onItemUseFinish(ItemStack stack, World worldIn, LivingEntity entityLiving) {
      ItemStack itemstack = super.onItemUseFinish(stack, worldIn, entityLiving);
      if (!worldIn.isRemote) {
         double d0 = entityLiving.getPosX();
         double d1 = entityLiving.getPosY();
         double d2 = entityLiving.getPosZ();

         for(int i = 0; i < 16; ++i) {
            double d3 = entityLiving.getPosX() + (entityLiving.getRNG().nextDouble() - 0.5D) * 16.0D;
            double d4 = MathHelper.clamp(entityLiving.getPosY() + (double)(entityLiving.getRNG().nextInt(16) - 8), 0.0D, (double)(worldIn.getActualHeight() - 1));
            double d5 = entityLiving.getPosZ() + (entityLiving.getRNG().nextDouble() - 0.5D) * 16.0D;
            if (entityLiving.isPassenger()) {
               entityLiving.stopRiding();
            }

            if (entityLiving.attemptTeleport(d3, d4, d5, true)) {
               worldIn.playSound((PlayerEntity)null, d0, d1, d2, SoundEvents.ITEM_CHORUS_FRUIT_TELEPORT, SoundCategory.PLAYERS, 1.0F, 1.0F);
               entityLiving.playSound(SoundEvents.ITEM_CHORUS_FRUIT_TELEPORT, 1.0F, 1.0F);
               break;
            }
         }

         if (entityLiving instanceof PlayerEntity) {
            ((PlayerEntity)entityLiving).getCooldownTracker().setCooldown(this, 20);
         }
      }

      return itemstack;
   }

how would this be implemented into a mod? would u create a procedure and then and the code into it?
