Okay so i’m new in unity and got some problem with shooting bullet in direction of shooter. Could someone help me solve this out?
Here are my classes:

using UnityEngine;
using System.Collections;

public class characterCombat : MonoBehaviour {
	#region --Pubs--
	public GameObject ammo;
	public string weaponName = "H&K";
	public int weaponMinDmg = 4;
	public int weaponMaxDmg = 15;
	#endregion
	#region --Privs--
	#endregion
	// Use this for initialization
	void Start () {
	
	}
	
	// Update is called once per frame
	void Update () {
		if(Input.GetKeyDown(KeyCode.F))
		{
			Vector3 playerPosition = new Vector3(transform.position.x,transform.position.y,transform.position.z);
			Instantiate(ammo,playerPosition,transform.rotation);
		}
	}
}

using UnityEngine;
using System.Collections;

public class bulletMove : MonoBehaviour {
	
	#region --Pubs--
		public int bulletRange;
		public float bulletSpeed;
		public GameObject shooter;
	#endregion
	#region --Privs--
		private Vector3 startPos;
		private Quaternion rotation;
	#endregion
	
	// Use this for initialization
	void Start () {
		shooter = GameObject.FindGameObjectWithTag("Player");
		startPos = shooter.transform.position;
		rotation = shooter.transform.rotation;
	}
	
	// Update is called once per frame
	void Update () {
		float distance = Vector3.Distance(startPos,transform.position);
		Debug.Log(distance);
		float move = bulletSpeed * Time.deltaTime;
		transform.Translate(startPos * move);
		if(distance >=bulletRange)
		{
			Destroy(gameObject);
		}
	}
}

I think the only change you have to make is on line 55:

transform.Translate(transform.forward * move);

This assumes that you want the bullet coming from the shooter. Your question says, " direction of shooter," which says towards the shooter. If you want the bullet to go towards the shooter, then there are a few more changes to make.

Note the typical way most folks shoot a bullet is to add a Rigidbody (which uses Unity’s physics engine).

Could you show me of example how to shoot bullet with rigidbody?
