Attack delay not working correctly

Questions & Answers
1

I have an enemy object that damages the player on collision. The script works correctly with no debug errors, however for some reason the attack delay is not working. I debug logged the timer to see if it was counting, which it was, so I am not really sure what the problem is!

Also, not a big issue but I may as well ask; Debug.Log shows that the enemy ‘hits’ the player once more after the player’s health reaches zero (taking it into -x amount). Can’t imagine this being a problem, but I am just curious why this may be happening.

Here is the code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class EnemyAttack : MonoBehaviour {

	public int enemyMaxHealth = 100; 
	public int enemyDamage = 10;
	public int enemyArmorRating = 10;
	public float enemyAttackDelay = 0.5f;

	private int enemyCurrentHealth;
	private float enemyAttackTimer;

	void Awake()
	{
		enemyCurrentHealth = enemyMaxHealth;
	}

	void Start()
	{
	}

	void Update()
	{
		enemyAttackTimer += Time.deltaTime;
	}

	public void DamageReceived(int gunDamageAmount)
	{
		enemyCurrentHealth -= gunDamageAmount - enemyArmorRating;

		if (enemyCurrentHealth <= 0f) 
		{
			gameObject.SetActive (false);
			Debug.Log ("Enemy killed!");
		}
	}

	void OnCollisionStay(Collision attack)
	{
		if (attack.gameObject.tag == "Player" && PlayerHealth.playerCurrentHealth >= 0 && enemyAttackTimer >= enemyAttackDelay)
		{
			PlayerHealth.playerCurrentHealth -= (enemyDamage - PlayerHealth.playerDefense);
			Debug.Log("You have been hit! Current Health: " + PlayerHealth.playerCurrentHealth);
		}
	}
}

I basically used this here after many hours of searching, and trial and error on my code. Also fixed the second problem by changing the PlayerHealth.playerCurrentHealth >= 0 to PlayerHealth.playerCurrentHealth > 0. Easy fix for a simple mistake, as the collision was being carried out WHEN health = 0.
