Question How do i do a special attack?

Hello guys, I've been thinking about how I can do a special attack. I want to do that when I press the letter E it does a lot of punches and stops after a while, for example it does a barrage of punches and then stops after 3 seconds, I already have the code for the combat system (i just follow a tutorial from Youtube:

) and i was wondering if someone can help me to make it.

Code (CSharp):

1.  public Transform AttackPoint;
2.     public float attackRange = 0.5f;
3.     public LayerMask enemyLayer;
4.     public int attackDamage = 40;
5.     public float attackRate = 2f;
6.     float nextAttackTime = 0f;
7.  
8.     // Update is called once per frame
9.     void Update()
10.     {
11.         //m1's
12.         if(Time.time >= nextAttackTime)
13.         {
14.             if (Input.GetButtonDown("Fire1"))
15.             {
16.                 attack();
17.                 nextAttackTime= Time.time + 1f / attackRate;
18.  
19.             }
20.         }
21.        
22.        
23.         //Barrage
24.         if (Input.GetKey(KeyCode.E))
25.         {
26.  
27.            
28.  
29.         }
30.        
31.     }
32.     void attack()
33.     {
34.         //Detect enemies in the range of attack
35.  
36.         Collider2D[] hitEnemy = Physics2D.OverlapCircleAll(AttackPoint.position, attackRange, enemyLayer);
37.        
38.         //Damage enemy
39.  
40.         foreach(Collider2D enemy in hitEnemy)
41.         {
42.             enemy.GetComponent<Dummy>().TakeDamage(attackDamage);
43.  
44.         }
45.     }
46.  
47.     private void OnDrawGizmos()
48.     {
49.       if(AttackPoint == null)
50.         { return; }
51.  
52.  
53.  
54.         Gizmos.DrawWireSphere(AttackPoint.position, attackRange);
55.     }
56. }
57.  

also i apologize for my grammar.

 

I would also like to make it able to attack in the direction I'm facing

 

Well done for getting it to work (mostly), also don't worry about your spelling/grammar, I've seen a LOT worse on here and other places

 

thank you so much, appreciate it
