I am working on an assignment for a course and I need to make the enemy deal damage to the player after 5 seconds of touching or being near the player.

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

public class EnemyController : MonoBehaviour {

public float LookRadius = 10f;
public float DamageRadius = 0.5f;
public float Time = 0f;

Transform target;
NavMeshAgent agent;

// Use this for initialization
void Start () {
    target = PlayerManager.instance.player.transform;
    agent = GetComponent<NavMeshAgent>();
}

// Update is called once per frame
void Update () {
    float distance = Vector3.Distance(target.position, transform.position);

    if (distance <= LookRadius)
    {
        agent.SetDestination(target.position);
    }
    if (distance <= DamageRadius)
    {
        
    }
}

}
I have all of this so far, I just don’t know what to put in the last “if” statement to get it to work.

public float LookRadius = 10f;
public float DamageRadius = 0.5f;
public float damageDelay = 5f;
private float damageTimer = 0f;
Transform target;
NavMeshAgent agent;
// Use this for initialization
void Start () {
target = PlayerManager.instance.player.transform;
agent = GetComponent();
}

// Update is called once per frame
void Update () {
    float distance = Vector3.Distance(target.position, transform.position);
    if (distance <= LookRadius)
    {
        agent.SetDestination(target.position);
    }
    if (distance <= DamageRadius)
    {
        damageTimer += Time.deltaTime;
        if( damageTimer > damageDelay )
        {
            damageTimer -= damageDelay;
            // Apply damage
            // Change according to your scripts
            Player player = target.GetComponent<Player>();
            if( player != null )
                player.ApplyDamage();
        }
    }
    else
    {
        damageTimer = 0;
    }
}

You can do this easily using Coroutines:

public float delay;
public bool immune = false;

public Update () {
	if (CheckHit())
		StartCoroutine(DamagePlayer(delay));
}

public bool CheckHit () {
	if (immune) 
		return false;
		
	// Do your own check here
	
	return true;
}

IEnumerator DamagePlayer (float time) {	
	// Make the player Immune so it doesn't trigger multiple times
	immune = true;

	// Wait the amount of time
	yield return new WaitForSeconds(time);
	DealDamage ();
	
}

void DealDamage () {
	Player player = target.GetComponent<Player>();
             if( player != null )
                 player.ApplyDamage();
				 
	immune = false;
}
