Unity help - rotations not working :(

Okay so I am working on a platformer in unity 2D. I have some animations for a character with a player controller attached (punch, kick and block, which work fine). When I move, my player controller calculates his velocity and depending on its value, if he is not jumping or blocking/kicking/punching he will be in the 'walk' or 'run' states (if not idle). Basically this just means his limbs rotate at a certain speed (the limbs are children of the player, who is a parent).

However, this simple task is turning out to be hard. I originally had the following script to make the limbs rotate:

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

public class Rotation : MonoBehaviour {

 private int b;

 void FixedUpdate () {
     b = PlayerController.b;
     float y = transform.localEulerAngles.z;
     transform.RotateAround (transform.position, Vector3.forward, 
b*45*Mathf.Sin(3*Time.fixedTime)-y);
 }
}

(Ignore the 'b').

This worked fine until I turned the character to the left, when the rotations started going haywire.

I decided to simplify and use the following script to rotate.

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

public class Rotation : MonoBehaviour {

float y;

void Start(){
    y = transform.localRotation.z;
    Debug.Log (y);
}

void FixedUpdate () {
    float u = y + 45 * Mathf.Sin (3 * Time.fixedTime);
    Quaternion rot = transform.localRotation;
    rot.z = u;
    Debug.Log (u);
    transform.localRotation = rot;
    }
}

How can this go wrong? This is not even rotating at all. I have tried debugging the angle and have noticed that the angle (of the limb I am looking at) changes for a few seconds (even though I can't see any rotation), then gets stuck at a certain value (usually about 45). What is happening? Am I missing something?

tl;dr I just want to have his limbs oscillate with time.

I think its best you make an animation for walking, and the way you can play it is you can have a variable like bool isWalking, and then you say if(isWalking){ animator.play(walkAnimation); }

As you can see there is a variable called 'animator' in mine. You should search up tutorials about the unity animator, those are very helpful. Hopefully this helps, if it does not I'm so sorry
