Issue with Slerping

Question

Hi there, I'm currently facing a pretty unfortunate issue. This here is my script to rotate an object up and down once again (a weapon recoil type effect) The whole thing does work, but the effects are only visible for 1-2 frames, which is not what I actually had in mind. Is there a way to make this rotation process last around one second?

 public void WeaponKick (){
     float kick = 2.0f;
     kick = Random.Range(recoil * 1.5f, recoil * 2.0f);

     kickRotation = Quaternion.Euler(item.transform.rotation.eulerAngles - new Vector3(0.0f, 0.0f, kick));
     item.transform.rotation = Quaternion.Slerp(item.transform.rotation, kickRotation, 0.7f);

 }

Thanks for any help, I'm pretty much lost here... :)

Do it in a coroutine:

 public void WeaponKick()
 {
     float kick = 2.0f;
     kick = Random.Range(recoil * 1.5f, recoil * 2.0f);
     kickRotation = Quaternion.Euler(item.transform.localEulerAngles - new Vector3(0.0f, 0.0f, kick));
     StartCoroutine(Recoil(item.transform, kickRotation, 0.5f));
 }
 
 IEnumerator Recoil(Transform trn, Vector3 kickRotation, float time)
 {
     Vector3 start = trn.localEulerAngles; // or use trn.eulerAngles for global rotation
     float curTime = 0;
     // send to kickRotation
     while (curTime < 1)
     {
         curTime += (Time.deltaTime / time) * 2;
         trn.localRotation = Quaternion.Slerp(trn.localRotation, Quaternion.Euler(kickRotation), curTime); // use trn.rotation for global rotation
         yield return null; // wait until next frame
     }
     curTime = 0;
     // send back to start rotation
     while (curTime < 1)
     {
         curTime += (Time.deltaTime / time) * 2;
         trn.localRotation = Quaternion.Slerp(Quaternion.Euler(kickRotation), trn.localRotation, curTime); // use trn.rotation for global rotation
         yield return null; // wait until next frame
     }
     trn.localEulerAngles = start;
 }
