/damage - A command for dealing (or healing) damage to mobs and players

Basically what's written on the tin - a command that makes dealing damage to entities easier. I even thought up the syntax for it to flesh it out:

/damage <targets> <damage_amount> <damage_type> <source> <knockback_amount>

<targets> - Pretty simple; what gets hit by the damage.

<damage_amount> - The amount of damage the entity will take. In addition, negative values can also be used and will instead heal the targeted entities.

<damage_type> - This one would have three options to determine what type of damage you would like to apply

1. physical - Damage dealt is affected by armor, enchant and status effects (like arrows, melee hits, etc.)

2. magic - Damage dealt bypasses armor, but is still affected by enchants and status effects (similar to instant damage, wither status, etc.); could potentially be broken up to variants to fit with protection enchants, such as blast or projectile

3. pure - Damage ignores all damage reduction (similar to Void damage, would be the default setting)

<source> - Allows you to define a source for what is dealing the damage, and would update player kill counts (in statistics) or totalKillCount scoreboards; it would also determine the "source" for applying knockback to affected mobs (can also be written via coordinates or tilde notation)

<knockback_amount> - applies knockback to targeted entities originating from the given source (would scale similar to the attackKnockback NBT on mobs); would also be able to apply on 0-damage attacks to allow for knockback application

  I was actually just about to post almost exactly the idea you've posted here,
  I've been working on a custom multiplayer gamemode using complex datapacks as the lead programmer,
  and one of the main things that's been holding us back has been the lack of ability to do custom damage amounts, so this command would be amazingly useful.

  
  I'd like to add:
  how I originally thought of this when I was going to post was something along the lines of:
  /damage <heal/deal> <target selector>* <amount> <source>* <type>
  (*uses @ target selecting)
  This could also potentially have a <fatal> true/false (defaulting to true) argument at the end that when set to false could mean that like poison, the damage can't set the player's health to lower than 1.

  I also wanted the idea of a knockback command, but due to the complexity, I thought that it would work better as it's own separate command (of course datapacks could still easily chain both together as if they were one), and that could probably work something like:
  /knockback <target selector>* <force> <direction> <allow resistance>*
  (*to set how much knockback resistance is ignored percentage based, defaults to 100% if left blank, going over 100% would mean that knockback resistance instead increases knockback).

  Either way, let's all hope that Mojang decides to add this overdue command some day.
  If this releases with 1.19 I honestly think that it'd automatically be basically one of the best updates for map/datapack makers.
