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… :slight_smile:

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;
}
