entity_hurt_player advancement trigger is triggered for non-entity damage but entity_killed_player is not

Confirmed in 20w21a.

Here is a simple workaround that can be used in 20w18a and above.

Create a deathCount scoreboard objective with the following command:

/scoreboard objectives add deathCount deathCount

Then, create an entity_hurt_player advancement with an entity_scores predicate condition that checks if the deathCount score increased:

{
  "criteria": {
    "entity_killed_player": {
      "trigger": "entity_hurt_player",
      "conditions": {
        "player": [
          {
            "condition": "entity_scores",
            "entity": "this",
            "scores": {
              "deathCount": 1
            }
          }
        ]
      }
    }
  }
}

It works well if the player has to die only once for the advancement to be granted. If the advancement has to be revoked with a reward function, a simple rewards parameter with a function reward can be added after criteria.

The reward function should have the following minimum code:

advancement revoke @s only <advancement>
scoreboard players reset @s deathCount

I’d also like to point out that if this were “fixed” (as in the trigger was made to only respond to entities), universal damage tracking would no longer be possible in datapacks, period. As it stands now, we can force this trigger to only respond to entities by including a check for the direct entity in the provided damage condition, so this bug doesn’t render any functionality unattainable.

The “fix” for this bug should 100% be to just change the name of the trigger to minecraft:player_damaged or something like that.
