this will help OnCollisionEnter2D is meant to trigger only the first frame the same collision occurs.
You want to use OnCollisionStay2D(), which triggers on every frame with a collision.

code :

private void OnCollisionStay2D(Collision2D collision)
{
    if (collision.gameObject.tag == "Enemy01")
    {
        GetComponent<AudioSource>().Play();

        // To take 5 - 30 damage per second:
        HPBAR.PlayHP -= Random.Range(5f,30f) * Time.deltaTime;

        if (HPBAR.PlayHP < 0)// Insures player HP bar doesn't read less than zero in GUI TXT
        {
            HPBAR.PlayHP = 0;

        }
        // Debug.Log("Ouch! " + HPBAR.PlayHP + " Left");
        if (HPBAR.PlayHP <= 0 && HPBAR.lives > 0)
        {
            HPBAR.lives--;
            HPBAR.LPfloat--;
            p5.transform.position = spawner.transform.position;
            HPBAR.PlayHP = Random.Range(100, 150);
            // Debug.Log("You're Dead!!! Lives left: " + (HPBAR.lives + 1));

        }
        else if (HPBAR.PlayHP <= 0 && HPBAR.lives <= 0)
        {
            SceneManager.LoadScene("DeathScene");
        }

    } // of player tag check

}// end of collision stay

private void OnCollisionExit2D(Collision2D collision)
{
    if (collision.gameObject.tag == "Enemy01")
    {
        // put "i quit touching the hurty thing" stuff here.
    }
}

should help you out You want the campers to run away from the player right? Then you should do

code :

Vector3 moveDirection = transform.position - Player.transform.position

character.Move(moveDirection.normalized * speed * Time.deltaTime);

Instantiated Enemy outputs double damage for every enemy spawning after him

it fixes the issue There are a few problems with your scripts...
I don't think you understand what a static variable is.

code :

public static bool inSight;

PlayerMovement.isEnemyAttacking

using UnityEngine;
using UnityEngine.UI;

public class PlayerHealth : MonoBehaviour
{
    public static float Health;
    public static float maxHealth = 100;

    private Text healthText;


    void Start()
    {
        healthText = GameObject.FindGameObjectWithTag("HealthPoints").GetComponent<Text>();

        //Make it full 100% health on start
        Health = maxHealth;
        RefreshHealthBar();
    }



    public void TakeDamage(float damage)
    {
        Health -= damage;
        RefreshHealthBar();

        if (Health <= 0)
            Die();
    }

    public void Die()
    {
        Health = 0;
        RefreshHealthBar();

        //TODO: Your code
    }

    void RefreshHealthBar()
    {
        healthText.text = "HEALTH: " + Health;
    }
}

 using System.Collections;
using UnityEngine;

public class EnnemyAI : MonoBehaviour
{
    public float AttackDamage = 1.0f;
    public float AttackSpeed = 1.0f;
    public float AttackRange = 1.0f;

    private bool isPlayerInSight;
    private GameObject target;
    private NavMeshAgent agent;


    // Use this for initialization
    void Start ()
    {
        target = GameObject.FindGameObjectWithTag("Player");
        agent = GetComponent<NavMeshAgent>();

        StartCoroutine(AttackLoop());
    }

    // Update is called once per frame
    void Update ()
    {
        if (isPlayerInSight)
        {
            agent.destination = target.transform.position;
        }
    }

    IEnumerator AttackLoop()
    {
        while (true)
        {
            //I don't know your attacking logic, so lets say they can attack in a 1 unit range
            while (Vector3.Distance(target.transform.position, this.transform.position) <= AttackRange)
            {
                Attack();
                yield return new WaitForSeconds(AttackSpeed);
            }

            yield return 0;
        }
    }

    void Attack()
    {
        target.GetComponent<PlayerHealth>().TakeDamage(AttackDamage);
    }

    void OnTriggerEnter(Collider other)
    {
        if (other.gameObject.tag == "Player")
        {
            isPlayerInSight = true;
        }
    }

    void OnTriggerExit(Collider other)
    {
        if (other.gameObject.tag == "Player")
        {
            isPlayerInSight = false;
        }
    }
}

Unity Survival Shooter Enemy taking no damage - Android

this will help You are already using Layer to make sure that the raycast hit just the GameObjects on the shootableMask layer which is the "Shootable" layer so layer issue problem is eliminated.
The only possible problem left is that the EnemyHealth script is not attached to the GameObject or maybe some of the GameObjects.

Cause player to take damage in Unity 2D

Any of those help I made two scripts. One that'll keep track of the player's health, health bar and cause the screen to flash when the player is damaged. The other script is meant to be placed on any object I wish to do damage to the player, on contact. My problem is, Nothing seems to be doing any damage to the player. ,
Make sure that the players Collider has isTrigger enabled.

code :

[Range(1,100)] public int attackDamage = 10;

private void OnTriggerEnter2D(Collider2D col)
{
    // gets PlayerHealth component on this or any parent object
    var health = col.GetComponentInParent<PlayerHealth>();
    if (health  == playerHealth)
    {
        Attack();
    }
}

private void Update()
{
    damaged = false;
}

public void TakeDamage(int amount)
{
    damaged = true;
    currentHealth -= amount;
    healthSlider.value = currentHealth;
}

player = GameObject.FindGameObjectWithTag("Player");
playerHealth = player.GetComponent<PlayerHealth>();

playerHealth = FindObjectOfType<PlayerHealth>();

private void OnTriggerEnter2D(Collider2D col)
{
    // gets PlayerHealth component on this or any parent object
    var health = col.GetComponentInParent<PlayerHealth>();
    if (health != null)
    {
        Attack(health);
    }
}

void Attack(PlayerHealth health)
{
    timer = 0f;
    if(health.currentHealth > 0)
    {
        health.TakeDamage(attackDamage);
    }
}

Unity 2D rotate the AI enemy to look at player

I hope this helps . You need a function that would flip your sprite, you can do that by changing the scale of the transform, and keep a boolean to check where it's facing bool facingRight;, so something like this

code :

void Flip(){
      Vector3 scale = transform.localScale;
      scale.x *= -1;
      transform.localScale = scale;
      facingRight = !facingRight;
}

if (Vector3.Distance(target.position,transform.position)<20)
    {

     transform.position=Vector2.MoveTowards(transform.position, target.position,speed*Time.deltaTime);
     if(target.position.x > transform.position.x && !facingRight) //if the target is to the right of enemy and the enemy is not facing right
        Flip();
     if(target.position.x < transform.position.x && facingRight)
        Flip();
   }
