Player attack sometimes wont work

Hey Guys, I have a problem. Im pretty new to Unity and i cant find a solution. I added melee Combat to my Platformer and it works (mostly). I added "timeBtwAttack" so the Player is not able to Spam the Attack Key.
My problem is that sometimes the Attack wont work. For example: I set the timeBtwAttack on 0.3 and press the Attackbutton 5 Times. Sometimes the first attack wont go off, sometimes 3 Attacks go off rly fast and the last 2 attacks wont work etc...
What i want is:
If i press the Attackbutton the Player should stand still and attack. After the attack the player should be able to move again.
But the most important thing is that the attack should go off when i press the button.
Maybe somebody can help me

Thanks

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class PlayerAttack : MonoBehaviour
6. {
7.     private Animator anim;
8.     private float timeBtwAttack;
9.     public float startTimeBtwAttack;
10.  
11.     public Transform attackLocation;
12.     public float attackRange;
13.     public LayerMask enemies;
14.     public int damage;
15.  
16.  
17.     private void Start()
18.     {
19.         anim = GetComponent<Animator>();
20.     }
21.  
22.     void Update()
23.     {
24.         if (timeBtwAttack <= 0)
25.         {
26.             if (Input.GetButton("Fire1"))
27.             {
28.            
29.                 anim.SetBool("isAttacking", true);
30.                 Collider2D[] enemiesToDamage = Physics2D.OverlapCircleAll(attackLocation.position, attackRange, enemies);
31.  
32.                 for (int i = 0; i < enemiesToDamage.Length; i++)
33.                 {
34.                     enemiesToDamage[i].GetComponent<Enemy>().TakeDamage(damage);
35.                 }
36.             }
37.             timeBtwAttack = startTimeBtwAttack;
38.         }
39.         else
40.         {
41.             timeBtwAttack -= Time.deltaTime;
42.             anim.SetBool("isAttacking", false);
43.         }
44.      
45.      
46.  
47.     }
48.  
49.     private void OnDrawGizmosSelected()
50.     {
51.         Gizmos.color = Color.red;
52.         Gizmos.DrawWireSphere(attackLocation.position, attackRange);
53.     }
54. }

 

I think there might be something missing with your "startTimeBtwAttack" value. Try initiating it, since it is not initiated, perhaps unwanted values might be assigned to that, thus occurring undesired attack cycles. Not sure if this helps tho. Good luck.

 

For any one else having this problem just go watch brackeys video abour melle combat. He implements the attack rate at 18.51. Thats what worked for me.
