nVault Top 15

Over the years I've seen many scripters ask how to create a top 15 for data that is stored in nVault. Since the nVault module has no retrieve-all or sorting functionality this is not possible without the use of nVault Utility. While not required to complete this, I am providing an example using the nVault Array include since I think this is a cleaner approach than storing all data as a string and then parsing components of the string for the calculation.

High-level explanation for how nVault Utility works:
nVault Utility uses the file natives to read data from the vault file in binary format. Each item (key:data) in nVault is stored at an offset within the file, with 0 being the position of the first record, the next record is positioned based off of the size of the previous record, etc. This offset, or location of player data, will be used as a reference to the player data to make this top 15 possible.

Steps for creating a Top 15:
  1. Read all records in the vault file and store the player-data offset and XP value to a 2-dimension array.
  2. Sort this array using the XP value as the sort value.
  3. Loop through this sorted array to build the top 15. With each iteration, the players data offset will be used to re-read their data from the vault. Any piece of data that is stored in the nVault array record can be used in the top 15 (name, steam id, xp, etc).
Requirements:Note: You must delete your vault file or prune all data before implementing this since nvault_read_array() will fail if you try to read data that was not stored using nvault_set_array().

Plugin chat commands:
  • top15 - Display the top 15.
  • loadtestdata - Loads 100 test records to the vault in 'Player_# [XP]' format. The players name includes their stored XP value so you can confirm it is sorting accurately.
PHP Code:
