Trying to enable image!

*I am new to programming, so I am sorry if I sound like an absolute noob*
I am working on a project revolving around creating a star system. I used this website as a baseline on creating it. I removed the unlocking levels portion and am mainly focused on only using the stars. Problem is, I cannot get the star images to enable/disable when I want them to. There are no errors in the console, and I cannot pinpoint the problem.

Below is the code for the LevelSelectScript attached to the Main Camera. The Debug.Log() even lists the correct image title I wanted enabled ("1star3"), but nothing seems to happen.

Code (CSharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4. using UnityEngine.UI;
5. public class LevelSelectScript : MonoBehaviour {
6.     //variable which holds the stars obtained  
7.     private int stars=0;
8.  
9.     //Level to load on button click. Will be used for Level button click event
10.     public void Selectlevel(string level){
11.         Application.LoadLevel("Level"+level); //load the level
12.     }
13.    
14.     //function to check for the levels locked
15.     void  SetStars (){
16.         //loop through the levels of a particular world
17.         for(int j = 1; j < LockLevel.levels; j++){
18.             //get the number of stars obtained for that particular level
19.             //used to enable the image which should be displayed in the World1 scene beside the individual levels
20.             stars = PlayerPrefs.GetInt("level"+j.ToString() +": stars");
21.             //enable the respective image based on the stars variable value
22.             GameObject.Find(j+"star"+stars).GetComponent<Image>().enabled = true;
23.             // ^^^-problem here?
24.             Debug.Log(j+"star"+stars);
25.         }
26.     }
27. }

This is another snippet of code attached to the Player in Level "Level1.1"

Code (CSharp):

1. protected void  GetStars (int stars){
2.        
3.         //set the playerprefs value of next level to 1 to unlock
4.         //also set the playerprefs value of stars to display them on the World levels menu
5.         for(int j = 1; j < LockLevel.levels; j++){
6.             int i = 0;
7.             if(currentLevel == "Level"+(i+1).ToString() +"." +j.ToString())
8.             {
9.                 PlayerPrefs.SetInt("level"+j.ToString() +": stars",1);
10.                 //check if the current stars value is less than the new value
11.                 if(PlayerPrefs.GetInt("level"+j.ToString() +": stars") < stars)
12.                     //overwrite the stars value with the new value obtained
13.                     PlayerPrefs.SetInt("level"+j.ToString() +": stars",stars);
14.             }
15.             i++;
16.         }
17.     }

Any help would be great! I just have no idea what I am doing wrong. I have been trying for the last few days to find a solution to no avail.

 

I'm not sure if this would help but ill post it anyways, this is how i cycle through and enable/disable game objects.

First create a public GameObject array and put all your stars in it.

Code (CSharp):

1. public GameObject[] stars;
2.     private int starIndex;
3.  
4.     void CycleStars()
5.     {
6.         int disableStar;
7.         //cycles through your array of stars to see which one is currently active
8.         for(disableStar = 0; disableStar < stars.Length -1; disableStar++)
9.         {
10.             if (stars[disableStar].activeInHierarchy == true)
11.             {
12.                 break;
13.             }
14.         }
15.         //disables previous star and enables new star
16.         stars[disableStar].SetActive(false);
17.         stars[starIndex].SetActive(true);
18. }
19.  

The variable starIndex would control which star you want to select, but you will have to use an if statement to make sure starIndex does not exceed the length of stars[].length -1.
