Right Click Detection(?)

[clever ore]

I was playing the Minecraft avatar add on pack and noticed that they have right click detection

when you left click(attack button) a certain tameable entity, instead of attacking it, it plays an animation

how could i achieve this? but also, what molang query can be used to trigger than animation?

You can use damage sensor to trigger an event with a
/playanimation command

"minecraft:damage_sensor": {
        "triggers": [
          {
            "on_damage": {
              "event": "example:animation"
            },
            "deals_damage": false
          }
        ]
      }

Use filters to detect when it is hit by a player

and having “deals_damage” set to false would prevent the mob from turning red and receiving knockback from the hit right?
