  Attack mechanics aren't a part of AC, which is for traditional non-combatative mechanics. For a rock-throwing system, you'd need to rely on a custom script that has a function that causes e.g. a Rigidbody to have a force applied. For example:

  using UnityEngine;
  
  public class RockThrowing : MonoBehaviour
  {
  
      public Rigidbody rockRigidbody;
      public Vector3 force;
  
      private void Awake ()
      {
          rockRigidbody.isKinematic = true;
          rockRigidbody.detectCollisions = false;
      }
  
      public void ThrowRock ()
      {
          Debug.Log ("Applying force to " + rockRigidbody, rockRigidbody);
          rockRigidbody.isKinematic = false;
          rockRigidbody.detectCollisions = true;
          rockRigidbody.AddForce (force);
      }
  
  }
  

  To call this script's "ThrowRock" function from within AC, you can use either the Object: Send message or Object: Call event Actions.

  I don't know where to put the action list ''Object: Send message or Object: Call event actions'' and in the sequence the Script , do I add both in the enemy's object? I did it that way and it didn't work, I don't know how to make the enemy throw stones towards the player within a time range. For rockThrowing I used the cube object and added a rigibody to the cube.

  You'll need to share details of all the objects involved - including the Rock with the Rigidbody.

  The Action is only necessary if you want to call it from within AC. You can click Run now in the ActionList's Inspector to test it, but when you run it automatically will depend on how/when you want to trigger the throwing effect.

  The object I used was a ''cube4'' prefab with a rigid body.

  I put the call on ''on start'' and the ''RockThrowing'' script on the enemy. Nothing happens.

  I changed the prefab object for what is in the scene and updated the reference in the script and in the action list and nothing happens. No error message appears, the only one is the one that already existed well before referring to the Enemy.

  You don't need to add the RockThrowing script to your NPC - only the rock object that is thrown.

  If you've got the script on the rock in the scene, and have the Action reference that rock, then the function should fire correctly.

  I have updated the script above to print a message when the function is called. Update your script with the above, and then look out for the message. When displayed, you can click the message to "ping" the Rigidbody that it's affecting. Which object is it then selecting in the Hierarchy?

  I made the necessary changes and it still doesn't work.

  

  The warning appears referring to the rock. It's in print.

  Looks like the Action is set up OK.

  Keep the rock un-parented for now - we can re-attach it to the NPC later, but let's simplify things and get the basic throwing effect working first.

  I've updated the script above to prevent the Rock from being a physics object until the throw command is called.

  Update the script, and move the Rock outside of the NPC's Hierarchy.

  Keep the Rock's Inspector open at runtime - you should find that its Rigidbody's Is Kinematic property becomes checked when the scene starts, and becomes unchecked when the throw command is called. If it doesn't seem to move at this point, try raising the force values and run the scene again.

  Now it worked. Thanks. Had to change throw strength from 6 to x 350 and y 2

  I removed the action that calls ''on start'' and used it in a trigger when the NPC goes over the trigger the action is triggered.

  He throws the stone, however this stone does not stay with him until he throws it, I tried to put it as a son and when the NPC throws the stone a few meters away, this stone is being dragged along with the NPC who is walking. Is there any method to solve this?

  Before the Object: Send message Action, insert an Object: Set parent Action. Set the Object to affect to the stone, and set the Method to Clear Parent.

  This will detach the stone from the NPC's Hierarchy just before the throwing function is called.

  It worked, thank you
