using UnityEngine;
using System.Collections;

[System.Serializable]
public class Done_Boundary
{
public float xMin, xMax, zMin, zMax;
}

public class Done_PlayerController : MonoBehaviour
{
public float speed;
public float tilt;
public Done_Boundary boundary;

public GameObject shot;
public Transform shotSpawn;
public float fireRate;
 
private float nextFire;

void Update ()
{
	if (Input.GetButton("Fire1") && Time.time > nextFire) 
	{
		nextFire = Time.time + fireRate;
		Instantiate(shot, shotSpawn.position, shotSpawn.rotation);
		GetComponent<AudioSource>().Play ();
	}
}

void FixedUpdate ()
{
	float moveHorizontal = Input.GetAxis ("Horizontal");
	float moveVertical = Input.GetAxis ("Vertical");

	Vector3 movement = new Vector3 (moveHorizontal, 0.0f, moveVertical);
	GetComponent<Rigidbody>().velocity = movement * speed;
	
	GetComponent<Rigidbody>().position = new Vector3
	(
		Mathf.Clamp (GetComponent<Rigidbody>().position.x, boundary.xMin, boundary.xMax), 
		0.0f, 
		Mathf.Clamp (GetComponent<Rigidbody>().position.z, boundary.zMin, boundary.zMax)
	);
	
	GetComponent<Rigidbody>().rotation = Quaternion.Euler (0.0f, 0.0f, GetComponent<Rigidbody>().velocity.x * -tilt);
}

}

place your fire function in start function

         void Start(){
          Instantiate(shot, shotSpawn.position, shotSpawn.rotation);
          GetComponent<AudioSource>().Play ();

              }
