Raycast Shooting Recoil

Physics

Hello, I have this script, How i can make an recoil?

            if (Input.GetKey(KeyCode.Mouse0) && Time.time > singleNextFire)
            {
                GetComponent<AudioSource>().Play();
                muzzleFlash.Stop();
                muzzleFlash.Play();

                singleNextFire = Time.time + fireRate;

                Vector3 rayOrigin = raycastcamera.ViewportToWorldPoint(new Vector3(0.5f, 0.5f, 0));
                RaycastHit hit;

                if (Physics.Raycast(rayOrigin, raycastcamera.transform.forward, out hit, maxRange))
                {
                    Instantiate(bulletHole, hit.point, Quaternion.FromToRotation(Vector3.up, hit.normal));
                    EnemyHealth enemy = hit.collider.GetComponent<EnemyHealth>();
                    if (enemy != null)
                    {
                        enemy.DamageEnemy(damage);
                    }

                    if (hit.rigidbody != null)
                    {
                        hit.rigidbody.AddForce(-hit.normal * hitForce);
                    }
                }
            }

Maybe if i make if i make:

Vector3 rayOrigin = raycastcamera.ViewportToWorldPoint(new Vector3(0.5f, 0.5f, 0));

To be randomly at 0.4 and 0.6 or an number between 0.4 - 0.6??

You need to make sure, that the player (or thing that shoots) has a rigidbody, then add some force in the direction opposite of the shooting direction, aka -transform.forward

3

But if i use Random.Range or something like this?

4

Oh, you mean to affect the bullet direction? You need to add some value to transform.forward with Random.Range

5

Can you give an example?

  if (Physics.Raycast(rayOrigin, raycastcamera.transform.forward, out hit, maxRange))
6

raycastcamera.transform.forward + new Vector3(randomvaluehere, randomvaluehere, rendomvaluehere)

I put this but nonthinking, maybe i need to use other numbers?

Your answer is here
You know, if you don’t learn a bit of programmic logic, just copy and paste some code from somewhere, then you wont get anywhere
