Shoot. Just Shoot

public var snowballPrefab : Transform; public var snowballSpeed : float = 6000;

function Update(){ if(Input.GetButton("Fire1")) { if(!snowballPrefab || !snowballSpeed) { Debug.Log("[Shoot] 'bulletPrefab' or 'bulletSpeed' is undefined"); }else{ var snowballCreate = Instantiate(snowballPrefab, GameObject.Find("SSpawnPoint").transform.position, Quaternion.identity); snowballCreate.rigidbody.AddForce(transform.forward * snowballSpeed); } } }

Try this, replace snowball with your game object. I am still trying to find out a better way:)

dont ask for scripts use the references and learn it yourself

put A empty game object in front of your gun ( where u want to shoot from) and name it "spawnPoint" then attach this script:

 var fireRate : float = 0.1;
 var Prefab: Transform;
 private var nextFire = 0.0;
 var speed : float = 50;
 function Update () {
     if(Input.GetKey("mouse 0")&&Time.time > nextFire){
     nextFire = Time.time + fireRate;
     var copy = Instantiate(Prefab,GameObject.Find("spawnPoint").transform.position,transform.rotation);
     copy.rigidbody.velocity = transform.TransformDirection(Vector3.forward * speed);
 
 }
 
 }

to the player, you can edit the fire rate, in the inspecter panel make sure to when it says prefab, add a game object there, such as a cube or sphere.

// attach this script with your gun and put an empty game object as a child of gun which work as spawn point of bullet
