Questions & Answers

I can fire bullets with this code from a FPS and barrel.

q1)How do I fire bullet at the angle I am facing? I might shoot forward but
my gun barrel is facing in the ground or up in the air?

q2)To keep track of all these bullets I use an Array or List? What is the common way to do this?

public Rigidbody projectile;
Void Update ()
{
Rigidbody mybullet;

mybullet = Instantiate(projectile, transform.position, transform.rotation) as Rigidbody;

mybullet.AddForce(transform.forward * 1000);

Keep track of the Bullet’s GameObject:

private List<GameObject> _bullets = new List<GameObject>();

void Update() {
    GameObject bullet = Instantiate(projectile, transform.position, transform.rotation) as GameObject;
    bullet.rigidbody.AddForce( gunTransform.forward * 1000.0f ); // prolly want to use ForceMode.Impulse here, depends on what you're attempting
    _bullets.Add(bullet);
}
