Problems with scale and rotation

Hi, guys!

I'm making an array of functions which contains the changes that occur to the array of objects. Everything works, but not the way I want to. hehe))) I would like to change the scale to less amount. But when I use floats (instead of 2), the script gives me errors. The rotation is supposed to be 20 (50) degrees around a transform's local Y axes. But it rotates 180 degrees most of the time.

If anyone can give me a clue how to make it work properly? Thank you!

THE CODE:

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

public class ChangeBlindness : MonoBehaviour {

 public List<GameObject> currentObjects; 

 
 void Start () {

     currentObjects = GetComponent<GenerateRoom> ().currentObjects;

 }
 

 void Update () {

             if (Input.GetKeyDown (KeyCode.G)) {
         
                     int changeFunction = Random.Range (1, 7);
                     int randomArrayObj = Random.Range (0, currentObjects.Count);
                     Changes (changeFunction, currentObjects [randomArrayObj]); 
             }
     }



 void ChangePos1 (GameObject gameObject){
     gameObject.transform.position = new Vector3 (gameObject.transform.position.x+1F, gameObject.transform.position.y,gameObject.transform.position.z);
 }
 
 void Rotate1 (GameObject gameObject){
     gameObject.transform.rotation = new Quaternion (gameObject.transform.rotation.x, gameObject.transform.rotation.y+20F, gameObject.transform.rotation.z, Time.deltaTime);
 }
 
 void Scale1 (GameObject gameObject){
     gameObject.transform.localScale = new Vector3 ( gameObject.transform.localScale.x *2, gameObject.transform.localScale.y *2, gameObject.transform.localScale.z *2);
 }
 
 void ChangePos2 (GameObject gameObject){
     gameObject.transform.position = new Vector3 (gameObject.transform.position.x+1.5F, gameObject.transform.position.y,gameObject.transform.position.z);
 }
 
 void Rotate2 (GameObject gameObject){
     gameObject.transform.rotation = new Quaternion (gameObject.transform.rotation.x, gameObject.transform.rotation.y+50F, gameObject.transform.rotation.z, Time.deltaTime);
 }
 
 void Scale2 (GameObject gameObject){
     gameObject.transform.localScale = new Vector3 ( gameObject.transform.localScale.x /2, gameObject.transform.localScale.y /2, gameObject.transform.localScale.z /2);
 }
 
 
 
 void Changes (int n, GameObject obj2change) {
     
     Debug.Log("Inside Changes function: " + obj2change.name);
     
     
     switch(n) {
         
     case 1: //ChangePos();
         
         ChangePos1(obj2change);
         Debug.Log("c1");
         
         break;
         
     case 2:  //Rotate();
         
         Rotate1(obj2change);
         Debug.Log("c2");
         
         break;
         
     case 3:  //Scale();
         
         Scale1(obj2change);
         Debug.Log("c3");
         
         break;
         
     case 4: //ChangePos();
         
         ChangePos2(obj2change);
         Debug.Log("c4");
         
         break;
         
     case 5:  //Rotate();
         
         Rotate2(obj2change);
         Debug.Log("c5");
         
         break;
         
     case 6:  //Scale();
         
         Scale2(obj2change);
         Debug.Log("c6");
         
         break;
         
     }
     
 }
