            "animations": {
                "attack": "controller.animation.attack"
            },
            "is_spawnable": false,
            "is_summonable": false
        },
// other default stuff ..........

You have to run the animation controller. In the player.json in the description section you have to insert the scripts parameter:

"scripts": {
   "animate": [
      "attack"
   ]
}
