Goal: Rotate paddle for pinball game when you press the A key.

Error:

CS1061: Quaternion does not contain a definition for eularAngles and no accessible extension method eularAngles accepting a first argument of type Quaternion could be found (are you missing a using directive or an assembly reference?)

After googling the issue and finding a 'loosely' related forum as well as looking up on Unity forums how eularAngles and Quaternion is supposed to be handled, I think my issue is that I haven't properly stated a class to 'normalise' the Quaternion. I have almost no understanding of these concepts.

Code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class paddleLeft : MonoBehaviour{

    private Transform myTransform;

    void Start() {
        myTransform = gameObject.transform;
    }

    void Update() {
        if (Input.GetKey(KeyCode.A)) {
            var ourRotation = myTransform.rotation.eularAngles;
            var newRotation = new Vector3(ourRotation.x, ourRotation.y, ourRotation.z   (5 * Time.deltaTime));
            myTransform.rotation = Quaternion.Euler(newRotation);
        }
    }
}

I tested the above code, which worked correctly, but I suggest using a simpler rotate alternative, as the transform class is stored directly inside the mono Behavior body and does not need to be re-saved.

void Update()
{
    if (Input.GetKey(KeyCode.A)) transform.Rotate(Vector3.forward, 5 * Time.deltaTime);
}

Thanks to KiynL I have a better alternative than my original approach. One that is much simpler to understand conceptually. I've implemented it as the below code. I need to make the number much higher for better result on the pinball and add maximum and minimum range but that's for later. Very happy with the result of this.

if (Input.GetKey(KeyCode.A)) {
   transform.Rotate(Vector3.forward, 50 * Time.deltaTime);
} else {
   transform.Rotate(Vector3.forward, -50 * Time.deltaTime);
}
