Restart wait regen after take damage

Hello everyone, I'm trying to create a regen system for the player, everything is fine when the player take damage for the first time, but, when it is taking it for the second time, the regen start again.
Any ideas? \:
Thanks in advance <3

Code (csharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class PlayerLifeManagerScript : MonoBehaviour
5. {
6.  
7.     [SerializeField]
8.     private float playerLife = 50f;
9.     private static float MAX_PLAYER_LIFE = 100f;
10.  
11.     public float regenRate = 1f;       //regen per seconds
12.  
13.     private bool isPlayerDead;
14.  
15.     private bool takingDamage, newDamage, damageDelay;
16.  
17.  
18.     void Update()
19.     {
20.         //if player is NOT taking damage regen life
21.         if (!takingDamage && playerLife < MAX_PLAYER_LIFE && !isPlayerDead)
22.         {
23.             playerLife += regenRate * Time.deltaTime;
24.         }
25.     }
26.  
27.     //called from enemy
28.     public void DamagePlayer(float damage)
29.     {
30.         //if is the first time just stop the regen, otherwise reset timer on while loop
31.         if (!takingDamage)
32.             takingDamage = true;
33.         else if (!newDamage)
34.             newDamage = true;
35.  
36.         //remove hp
37.         playerLife -= damage;
38.  
39.         //stop all if player is dead
40.         if (playerLife < 0)
41.         {
42.             playerLife = 0;
43.             isPlayerDead = true;
44.         }
45.  
46.         //if is the first time of damage taken
47.         if(!damageDelay && !isPlayerDead)
48.             StartCoroutine(RestoreLife());
49.     }
50.  
51.     private IEnumerator RestoreLife()
52.     {
53.         //close the door behind you
54.         damageDelay = true;
55.  
56.         float startTime = Time.time;
57.  
58.         //keep loop until the actual time is less than actual time plus 3 seconds
59.         while (Time.time < startTime + 3)
60.         {
61.             //if second attack incoming
62.             if (newDamage)
63.             {
64.                 //reset timer
65.                 startTime = Time.time;
66.  
67.                 //reset variable
68.                 newDamage = false;
69.             }
70.             yield return null;
71.         }
72.  
73.         //otherwise if nothing happen in 3 seconds, start regen again
74.         takingDamage = false;
75.         damageDelay = false;
76.     }
77. }
78.  
79.  
80. [code/]

 

I prefer taking almost everything like this out of Update and control it more directly... a snippet from a health script of mine:

Code (csharp):

1.  
2.  
3.  
4. public void Hit(ProjectileInfo info)
5. {
6.      CancelInvoke("Regen"); // if hit... cancel any regen
7.  
8.      //Do damage stuff
9.  
10.      Invoke("Regen", regenAfterDamageTimer);
11. }
12.  
13. public void Regen()
14.     {
15.         if ((health < maxHealth))
16.         {
17.             health += regenAmount;
18.             if (health > maxHealth)
19.             {
20.                 health = maxHealth;
21.             }
22.             else{
23.                  Invoke("Regen", regenTickTimer);
24.             }
25.         }
26.     }
27.  
28.  

 

The easier way would probably be using properties, and having the setter cap health to the max. This way you can have the regen run constantly and not care. So long as you don't want to know whether the character is actively regenning (say for a particle effect), this is probably the simplest.

 

Thanks, it works like a charm. I was stuck all day to try to solve this problem, I was also uncomfortable about using the Update, because why I need to call regen every frame when I don't need it? And now you found me a solution more easier. Thanks again dude, I appreciate it. =)
