My script only partially works

Question

Jumping over enemy once changes color, jumping over it a second time destroys the enemy, then the enemy re-spawns, those parts work. The problem is, the number of times jumped doesn't reset back to zero, so after the enemy re-spawns jumping over the enemy once destroys it. Revering to starting color after enemy is destroyed works too.

How do I do it so you need to jump over an enemy twice each time it re-spawns?

  using System.Collections;
     using System.Collections.Generic;
     using UnityEngine;
      
     //Destroy enemy 2 after jumping twice, jumping once turns him to blue
      
     public class DestroyEnemy2 : MonoBehaviour //enemy 2
     {
         [SerializeField] Transform Enemy2Respawn;
      
         private Renderer rend;
         private Color colorToTurnTo = Color.blue;
         private Color colorToTurnToo = Color.grey;  // after destroying enemy, changes color back to original
      
      
     void Start()
        
       {
             rend = GetComponent<Renderer>();
             rend.enabled = true;
             Physics2D.queriesStartInColliders = false; //since ray starts from the enemy...
                                                        //...game object, this will make it so it won't...
                                                        //...destroy itself right when the game starts
         }
      
         bool waitingForFirstHit = true;
         bool waitingForSecondHit = false;
         float timeDelay = 0.2f;
      
     void Update()
         {
            
             RaycastHit2D hitInfo = Physics2D.Raycast(transform.position, Vector3.up, 5);
      
             if (hitInfo.collider.gameObject.tag == "Player")
             {
                 if (waitingForFirstHit)
                 {
      
                     ChangeColor();
                     waitingForFirstHit = false;
                     waitingForSecondHit = true;
                 }
                 else if (waitingForSecondHit && timeDelay < 0)//when it's >0 it causes it to be destroyed after one jump.  when its <0 , it just changes color and waits till you do a second jump
                 {
                     destroyEnemy();
                     transform.position = Enemy2Respawn.position;
                     Score.scoreValue += 50;
                 }
             }
      
         if (waitingForSecondHit)
             {
                 timeDelay -= Time.deltaTime;
             }
         }
      
         void ChangeColor()
         {
             rend.material.color = colorToTurnTo;
            
         }
      
         void ChangeColorr() //turn back to original after destroying enemy
         {
             rend.material.color = colorToTurnToo;
      
         }
      
         void destroyEnemy()
         {
      
             {
                 Destroy(GameObject.FindWithTag("Enemy2"));
                 ChangeColorr();
      
              }
      
         }

It seems the boolean values aren't being reset to their initial values upon death. Have you tried reassigning them in destroyEnemy()?

I tried, but I am not sure if I did it right

I believe this script does what you are trying to achieve. Let me know if it works.

Edit: Changed the script to the final version that solved the issue.

 using UnityEngine;
 
 public class MyNewClass : MonoBehaviour
 {
     [SerializeField] private int hitMaxAmount = 2;
     public LayerMask WhatCanIHit;
 
     private const float checkHitDelay = 0.2f;
     private float checkHitTime;
     private bool isCheckHitTime;
     private bool isCheckHit = true;
     private int hitCount;
 
     void Update()
     {
         // Only check for hits if true
         if (isCheckHit)
         {
             // Use a layer mask to stop this raycast from hitting the base object
             RaycastHit2D hitInfo = Physics2D.Raycast(transform.position, Vector3.up, 5, WhatCanIHit);
             Debug.DrawRay(transform.position, Vector3.up * 5f, Color.red);
 
             // Check if it's hitting a collider
             if (hitInfo.collider != null)
             {
                 // Use CompareTag for better performance
                 if (hitInfo.collider.CompareTag("Player"))
                 {
                     Debug.Log("Hit count: " + hitCount);
                     isCheckHit = false;
                     isCheckHitTime = false;
                     hitCount++;
 
                     if (hitCount == 1)
                     {
                         Debug.Log("Got hit once, change color");
                         // Change Color
                     }
 
                     if (hitCount >= hitMaxAmount)
                     {
                         Debug.Log("Destroy Enemy");
                         // Destroy Enemy and stuff
 
                         // Reset hit count to let it run again
                         hitCount = 0;
                     }
                 }
             }
         }
 
         if (!isCheckHitTime)
         {
             checkHitTime += Time.deltaTime;
             if (checkHitTime >= checkHitDelay)
             {
                 Debug.Log("You can hit again");
                 isCheckHitTime = true;
                 isCheckHit = true;
                 checkHitTime = 0.0f;
             }
         }
     }
 }
