Adding force to a bullet

Question

I'm making a FPS on Unity (yeah yeah not original but who cares) and I'm doing okay. I've got the FPS control going with the camera following it, I got the imported models and particle effects. There's just a problem that is preventing me from moving on to shooting targets and stuff. I made a little Instantiate script to make bullets appear. The appearing bit works but I want to add force to the bullets, of course, so I made t$$anonymous$$s little Javascript:

 var thePrefab : GameObject;
 
 var power : float = 100.0;
 
 function Update () {
 
  
 if(Input.GetKeyDown(KeyCode.S)){
 
 var instance : GameObject = Instantiate(thePrefab, transform.position, transform.rotation);
 thePrefab.rigidbody.AddForce(Vector3(0, 0, power));

Surely t$$anonymous$$s should make the bullets shoot forwards by 100 units when I press the S button, right? Well, not$$anonymous$$ng happens. When I press S, the bullet appears and then drops to the ground because of rigidbody, but there's no force! Any help!? Sorry if t$$anonymous$$s is a really easy mistake, I'm still learning.

assuming that the rigid body of your prefab is properly setup, you need to add the force to the rigidbody of your instanciated object ('instance'), not the prefab you use as template for instanciation.

Don't worry now , lads I've figured it out. I took out the force bit off t$$anonymous$$s script and made a new script like t$$anonymous$$s:

[CODE] var force : float = 100;

function Update () {

if(Input.GetKeyDown(KeyCode.S)){

rigidbody.AddForce(transform.forward * force);

}

} [/CODE]
