[SOLVED] How do I check if player is still inside boss' collider?

I've got a boss enemy set up and the way it works is that if the player hits it, the player loses some health and the boss loses some health too. But, there is a glitch that after the player got hit by the boss once and stays inside the boss, the player basically can't lose health because OnTriggerEnter2D only calls once. I know I can use OnTriggerStay2D but the boss loses health too quickly as the method is called once per frame. How do I ensure that if the player is still within boss' collider, it will lose health?

Extra info: I've set up my player a short invincibility ability if it hits any enemy.

Boss OnTriggerEnter2D script:

Code (csharp):

1. void OnTriggerEnter2D(Collider2D other)
2. {
3.     if (other.gameObject.tag == "Player" && other.GetComponent<PlayerController>().invincible == false)
4.     {
5.         stats.CurHealth -= stats.playerCollisionDmg;
6.     }
7. }

Player's OnTriggerEnter2D script:

Code (csharp):

1. IEnumerator OnTriggerEnter2D(Collider2D other)
2. {
3.     if(other.GetComponent<EnemyStatsController>() != null)
4.     {
5.         if (!invincible)
6.         {
7.             stats.CurHealth -= other.GetComponent<EnemyStatsController>().collisionDamage;
8.             yield return new WaitForSeconds(0.01f);
9.             invincible = true;
10.             GetComponent<Animator>().enabled = true;
11.             yield return new WaitForSeconds(5f);
12.             invincible = false;
13.             GetComponent<Animator>().enabled = false;
14.             GetComponent<SpriteRenderer>().enabled = true;
15.         }
16.     }
17. }

 

OnTriggerStay with a simple time check sounds like the simplest approach

Code (csharp):

1.  
2. //pseudo
3. OnTriggerEnter()
4. {
5. impactTime = Time.time
6. }
7.  
8. OnTriggerStay()
9. {
10. if(Time.time > impactTime + damageDelay)
11. {
12. DoDamage()
13. impactTime = Time.time
14. }
15. }
16.  

 

This solution worked, thanks!
