2d sprite Animation - Fire at frame

Question

Hi guys i am new on this forum i would ask a question about my script problem . i have a ninja that shoot shuriken but my problem is that he must shoot only when the attack animation arrive to 6 image (name of the sixth sprite is 6 lol) how i can do ? Script is this

using UnityEngine; using System.Collections;

[RequireComponent (typeof(Rigidbody2D))] public class AI : MonoBehaviour {

 GameObject player,enemy;
 public GameObject shuriken;
 public bool dis = false;
 Rigidbody2D rb;
 
 public Transform shuriken_origin;
 public float speed;
 public float distance;
 LineRenderer range;
 public Transform target, eyes;
 public float Range_Attack = 17f;
 public SpriteRenderer sprite;
 Animator anim;
 
 public Vector3 theScale;
 public bool touchedleft = false;
 public bool touchedright = false;
 public Vector2 enemyvel;
 public float speedtoleft= -5;
 
 void Start () {

     rb = this.GetComponent<Rigidbody2D>();

     player = GameObject.FindGameObjectWithTag("Player");
       
     anim = GetComponent<Animator>();
     Vector2 enemyvel = rb.velocity;
     Vector3 theScale = transform.localScale;
     theScale.x *= -1;
     transform.localScale = theScale;
 }
 
 
 void Update () {

     distance = Vector2.Distance(eyes.transform.position, target.transform.position);
     Vector2 enemyvel = rb.velocity;
     enemyvel.x = speed;
     rb.velocity = enemyvel;
     
     Attack();
 }
 void FixedUpdate()
 {              
    
 }

 void OnTriggerEnter2D(Collider2D col)
 {
     Flip();
     if (col.gameObject.name == "right")
     {
         speed = speedtoleft;
         enemyvel = new Vector2(rb.velocity.x * speedtoleft, 0);           
         touchedright = false;
         touchedleft = true;
         Flip();

     }
     if (col.gameObject.name == "left")
     {
         speed = 5;
         enemyvel = new Vector2(rb.velocity.x * speed, 0);
         touchedleft = false;
         touchedright = true;
         Flip();
     }

     
 }


 public void Flip()

         theScale.x *= 1;
         transform.localScale = theScale;
     }
     
  }
 void Attack() // questo metodo è stato un trip 
 {
     Vector2 direction = target.transform.position - transform.position;

In your animator you can specifically add behavior to one of your states. So if you go in your animator and click on your attack state, go in add behaviour, write a script which says after how long it should instantiate the shuriken and you should be good to go !!

'FramaData' is actually a thing!

I found it in the UnityEngine.Experimental.Director namespace and is used by the Animator.

It is a struct (System.ValueType) which seems to hold information on each frame. I assume this is the type used by the Frame Debugger. Given the existence of this Type and the fact that the Frame Debugger seems to work frame to frame it follows that there absolutely must be a way to manipulate the Animator Per-Frame, rather than the time and transition methods which are currently exposed.

the members of this class are as follows:

 int updateId
 float time
 float lastTime
 float deltaTime
 float timeScale
 double dTime
 double dLastTime
 double dDeltaTime
 double dtimeScale

So with little else to go on, I am assuming in this case that updateID represents the frame number.

I've not attempted to use this yet as Im still trying to find where to access the populated frame info, as this is not exposed in the Animator.

I just wanted to put this info somewhere and this was the most recent Animator-by-frame question. Sorry if it doesnt help you at all OP.

It does seem I might be disappointed as so far the only usage I can see for this in the Engine is by the Profiler.

@Eric5h5 and @Bunny83 Apologies for namedropping you dudes. You are highly versed with Unity internals so i would appreciate it greatly if you could solidify this or $$anonymous$$r it apart. No obligation, of course.
