shooting somthig

var projectile : Rigidbody; private var speed = 5;

function Update() { if(Input.GetButtonDown("Fire1")) { var instantiatedProjectile : Rigidbody = Instantiate(projectile, transform.position, transform.rotation);

 instantiatedProjectile.velocity =transform.TransformDirection(Vector3(speed, 0, 0));
     }

This is very simple to do. Try this and it will shoot what you want to shoot.

 //place your name of shooting target here. In inspector the projectile has to have a rigidbody
 var gameObject = Rigidbody;
 
 function Update ()
 {
      //When you the left mouse button fires the gameObject
      if ( Input.GetButtonDown (Fire1) )
      {
          //the shooting part of the function. Create empty gameObject place under your player and name spawnPoint. Then place this script on top of main player gameObject
          var gameObject : Instantiate(gameObject, transform.Find(spawnPoints).transform.position, Quaternion.identity);
 
          //adding force to projectile
          Rigidbody.AddForce : gameObject(forward * 500);
      }
 }

This script is very easy to make and use.
