About

Andrew's Datapack Utils is a Fabric/NeoForge Mod aimed at creating useful utilities for datapacks (mainly for datapack functions). It adds a command which holds most of the utilities, and allows modification of player data using /data and /execute store, allowing for easy manipulation of players and allows for things that were previously impossible.

Features

• Basic Math Calculation
  • used by using the /aputils calc <add|sub|mul|div|power|sqrt> command. Works great with /execute store result and function macroes.
• Editing Player Data
  • Normally, you can't use /data or /execute store (result|success) entity to change player entity data, it just throws an error, Unable to modify player data, and doesn't change anything. With this mod, that restriction is removed, allowing for easy modification of player entity data. Note that not everything can be modified, attempting to change certain values such as Motion or Pos does nothing. Use other commands such as /aputils velocity or /tp to change these instead.
• /aputils velociy <xyz> [add|set]
  • allows you to manipulate the velocity of entities in ways you can't with normal methods
  • requires permission level 2, meaning you nead cheats in a single player world or permission level 2 in a server
• /aputils attack_cooldown <player>
  • Outputs the attack cooldown progress of the provided player, as a percent if using /execute store result.
• aputils despawn <entities> [force]
  • Despawns one or more entities.
  • If force isn't applied and the target selecter includes one or more players at the time of the command being run (not if the selector allows players), the command fails.
  • Requires permission level 2, or permission level 4 if force is included
• aputils check_damage <entity> [type]
  • Returns true if the entity took damage on the tick the command was run, and type isn't provided
  • Returns true if the entity took damage of the provided type on that tick, if type is provided.

Datapacks can detect if this mod is installed using /aputils heartbeat, which always outputs 1 to /execute store result. Datapacks can detect if the NeoForge or Fabric version of the mod is being used. Returns 1 if NeoForge is being used and 0 if Fabric is being used.

Notes

This can be included in any modpack without my permission.

If you want to port this to Forge, go ahead.

Fun Facts

This is the first actual mod I've made in my entire history of Minecraft development. Before this I've only ever made datapacks for minecraft.
