A way to run code during WaitForSeconds?

Question

Hello everyone!

I currently have a character in my game that can attack by pressing a certain button. When that button is pressed, i also want him to dash in that direction for a bit, before i let the player control him again.

This is how i fix it right now:

  if (Input.GetKeyDown(KeyCode.Z))
             {
                 Attack();              
  
                 StartCoroutine(Dash(moveX, moveY, dashSpeed, dashTime));
             }

 void Attack()
     {
         Collider2D[] hitenemies = Physics2D.OverlapCircleAll(attackPoint.position, attackRange, 
         enemyLayers);
 
         foreach(Collider2D enemy in hitenemies)
         {
             Debug.Log("I hit " + enemy.name);
             enemy.GetComponent<EnemyScript>().TakeDamage(attackDamage);
         }
     }

 
 IEnumerator Dash(float moveX, float moveY, float dashSpeed, float seconds)
     {
         //canMove allows the player to move
         GetComponent<PlayerMovement>().canMove = false;
 
         //This makes the player dashes at the right direction
         playerrb.velocity += new Vector2(moveX * dashSpeed, moveY * dashSpeed);
 
         yield return new WaitForSeconds(seconds);
 
         GetComponent<PlayerMovement>().canMove = true;
     }

(I left out a bit of code that i did not think was necessary, but feel free to correct me in the comments)

However, the attack function is only called at the very beginning. Meaning that, when the player dashes, it does not registers if an enemy is in the "attack circle" and thus, does not attack it.

So, my problem is this. Is there a way to somehow run this Attack function during a waitforseconds? Or can i solve this problem in a better way?

Feel free to ask questions about the code or the game, if you need it

Thanks in advance!

What you can do is replace WaitForSeconds with a manual poll loop and call your attack function while that loop is running, i.e.

 IEnumerator Dash(float moveX, float moveY, float dashSpeed, float seconds)
 {
     //canMove allows the player to move
     GetComponent<PlayerMovement>().canMove = false;
  
     //This makes the player dashes at the right direction
     playerrb.velocity += new Vector2(moveX * dashSpeed, moveY * dashSpeed);
  
     // Accumulate the amount of time that has passed per frame until we reach the desired time
     for (float t = 0f; t < seconds; t += Time.deltaTime)
     {
         // Wait for the next frame
         yield return null;
         // Run the attack function now on the new frame
         Attack ();
     }
  
     GetComponent<PlayerMovement>().canMove = true;
 }

Hmm right, this is actually a more efficient method than $$anonymous$$e
