Player Shoot Script

using System.Collections;
using System.Collections.Generic;
using System.Collections.Specialized;
using System.Diagnostics;
using System.Runtime;
using UnityEngine;
public class PlayerShooting : MonoBehaviour
{
public GameObject BulletPrefab;
public Transform BulletSpawn;
public float damage = 5f;
public float TimeBetweenShots = 0.3333f;
public float m_timeStamp = 0f;
// Ammo
public int maxAmmo = 10;
private int currentAmmo;
public float reloadTime = 1f;
private bool isReloading = false;
//Gun Damage

//Crosshair


void Start ()
{
// Ammo
currentAmmo = maxAmmo;
//Crosshiar

}


void FixedUpdate ()
{
// Ammo
if (isReloading)
return;
if (currentAmmo <= 0)
{
StartCoroutine(Reload());
return;
}

if ((Time.time >= m_timeStamp) && (Input.GetKey(KeyCode.Mouse0)))
{
Fire();
m_timeStamp = Time.time + TimeBetweenShots;
}
//Crosshair

}
// Ammo
IEnumerator Reload()
{

isReloading = true;
yield return new WaitForSeconds(reloadTime);
currentAmmo = maxAmmo;
isReloading = false;
}
void Fire ()
{
// Ammo
currentAmmo--;

var bullet = (GameObject)Instantiate(BulletPrefab, BulletSpawn.position, BulletSpawn.rotation);
// Add velocity to the bullet
bullet.GetComponent<Rigidbody>().velocity = bullet.transform.forward * 50 ;
// Destroy thebullet after 2 seconds
Destroy(bullet, 1.0f);
//Enemy Target Instead of "hit" I had to put "bullet"

}
}


Enemy Attack Script
using System.Collections;
using System.Collections.Generic;
using System.Security.Cryptography;
using UnityEngine;
public class EnemyAttack : MonoBehaviour {
//public float damage = 5f;
[SerializeField] private Transform player;
[SerializeField] private Transform Spawn;
private void OnTriggerEnter(Collider other)
{

if (other.tag == "Player")
{
Destroy(other.gameObject);
}
else if(other.tag == "Bullet")
{
//Score Count what if i can add the same line for the player???
Destroy(gameObject);
ScoreCount.scoreValue += 10;
}
}
}

 

Hey, first of all please use code tags.
As i can see you dont store health anywhere. So start with that. You could make it its own component. When you collide with something and checked if its an enemy or the player, get this health component and subtract the damage from the health value. Damage over time would be handled slightly different, but that's a good place to get started. You should be able to find plenty of tutorials on these topics tho, so check some of them on youtube of other sites.

 

Ohh okay

many thanks
