How to Implement First Shot Accuracy?

Questions & Answers
1

I am making a fps in unity and i have implemented weapon accuracy by adding random number with the range of my “bulletSpread” to the camera.transform.forward. It works perfectly however I want the first shot from a weapon to be 100% accurate (or close to it). Here is the code for my raycast.

Also for some reason the debug.drawray is not working

rayDirection = fpsCam.transform.forward;
        rayDirection.x += Random.Range(-bulletSpread, bulletSpread);
        rayDirection.y += Random.Range(-bulletSpread, bulletSpread);
        rayDirection.z += Random.Range(-bulletSpread, bulletSpread);

        RaycastHit hit;
        if (Physics.Raycast(fpsCam.transform.position, rayDirection, out hit, range))
        {
            Debug.Log(hit.transform.name);
            Debug.DrawRay(fpsCam.transform.position, rayDirection);

            Target target = hit.transform.GetComponent<Target>();
            if (target != null)
            {
                target.TakeDamage(damage);
            }

            GameObject impactGo = Instantiate(impactEffect, hit.point, Quaternion.LookRotation(hit.normal));
            Destroy(impactGo, .1f);
        }

private void Shoot(bool useSpread) {
// …
if(useSpread) {
rayDirection.x += Random.Range(-bulletSpread, bulletSpread);
rayDirection.y += Random.Range(-bulletSpread, bulletSpread);
rayDirection.z += Random.Range(-bulletSpread, bulletSpread);
}
// …
}
void Update() {
// GetMouseButtonDown will only fire on the first frame the mouse is pressed,
// this would be our first shot
if(Input.GetMouseButtonDown(0)) {
// First frame mouse is down, don’t use spread.
Shoot(false);
} else if(Input.GetMouseButton(0)) {
// Mouse is held down, use spread.
Shoot(true);
}
}

Thank you for the reply I will try this when I get home my only question is that since not all of my weapons are automatic, won’t those have 100% accuracy on all of their shots?
