Level Selector - Level Images for Brick Breaker

Question

I am trying to make a level selector scene where players unlock levels and it displays a picture of the level so they can track their progress.

I have done the level unlocker and selector system, Im stuck on the images being displayed on the Raw Image component.

I have got the level properties in a class, they all load perfectly fine. I need the 'LevelTexture' to be in that class too.

If the 'LevelTexture' are not in the class then it loads fine, but as soon as I move the variable into the class it no longer works.

I have a feeling its got something to do with (Texture). if its '(Texture)LevelImage', it works find, but as soon as I put it in the class it now needs to be 'level.LevelTexture'. and I have no idea where to put the (Texture) part now.

     public class Level
     {
         public string LevelText;
         public int LevelID;
         public int Unlocked;
         public bool IsInteractable;
         public Texture LevelTexture;
         public Button.ButtonClickedEvent OnClickEvent;
     }
 
 
 
    // public Texture LevelTexture;

 void Start ()
 {
     levelManager = GameObject.FindObjectOfType<LevelManager>();
     FillList();
 }

 void FillList()
     {
         foreach (var level in LevelList)
         {
             //Level button creation and name
             GameObject newbutton = Instantiate(levelButton) as GameObject;
             LevelButton button = newbutton.GetComponent<LevelButton>();
             button.LevelText.text = level.LevelText;
             img = (RawImage)GameObject.Find("Image").GetComponent<RawImage>();
 


         //Level locked/unlocked
         if (PlayerPrefs.GetInt("LevelsUnlocked") >= level.LevelID)
         {
             print("Unlocked" + level.LevelID);
             level.Unlocked = 1;
             level.IsInteractable = true;


             img.texture = level.LevelTexture;                //This line has the issue.

           //img.texture = LevelTexture;


             print("Image loaded: " + level.LevelTexture);
             //  LevelPeak.sprite = level.LevelImage;
         }

         //Button Update
         button.unlocked = level.Unlocked;
         button.GetComponent<Button>().interactable = level.IsInteractable;
         button.GetComponent<Button>().onClick.AddListener(() => levelManager.LoadLevel(button.LevelText.text));

         newbutton.transform.SetParent(Spacer, false);
     }
 }

If anyone can help it would be greatly appriciated

Answer 1

You now have a class inside you class! Is this your intention?

If this IS your intention, this means that your class should be serializable and should be placed outside the MonoBehaviour class.

Example:

 [Serializable]
 public class Level
 {
     public string LevelText;
     public int LevelID;
     public int Unlocked;
     public bool IsInteractable;
     public Texture LevelTexture;
     public Button.ButtonClickedEvent OnClickEvent;
 }
 
 public class LevelSelector : MonoBehaviour
 {
     public Level Level;
 
     // public Texture LevelTexture;
         private void Start()
         {
         }
     
 }

Is this is NOT intention you should leave out the bracket ;-p

 public class Level : MonoBehaviour
      {
          public string LevelText;
          public int LevelID;
          public int Unlocked;
          public bool IsInteractable;
          public Texture LevelTexture;
          public Button.ButtonClickedEvent OnClickEvent;
  
  
     // public Texture LevelTexture;
  void Start ()
  {
      levelManager = GameObject.FindObjectOfType<LevelManager>();
      FillList();
  }
  void FillList()
      {
          foreach (var level in LevelList)
          {
              //Level button creation and name
              GameObject newbutton = Instantiate(levelButton) as GameObject;
              LevelButton button = newbutton.GetComponent<LevelButton>();
              button.LevelText.text = level.LevelText;
              img = (RawImage)GameObject.Find("Image").GetComponent<RawImage>();
  
          //Level locked/unlocked
          if (PlayerPrefs.GetInt("LevelsUnlocked") >= level.LevelID)
          {
              print("Unlocked" + level.LevelID);
              level.Unlocked = 1;
              level.IsInteractable = true;
              img.texture = level.LevelTexture;                //This line has the issue.
            //img.texture = LevelTexture;
              print("Image loaded: " + level.LevelTexture);
              //  LevelPeak.sprite = level.LevelImage;
          }
          //Button Update
          button.unlocked = level.Unlocked;
          button.GetComponent<Button>().interactable = level.IsInteractable;
          button.GetComponent<Button>().onClick.AddListener(() => levelManager.LoadLevel(button.LevelText.text));
          newbutton.transform.SetParent(Spacer, false);
      }
  }

Yes, my intentions were to have a class there. I have quite a few levels so that keeps it in an array like this:

alt text

There you will also be able to see that I am storing the Level texture image in the editor

There you will see once I click play, it loads the level selection menu, but not the images. The Texture is still blank on the Image.

This is what I dont understand, its not setting the texture and I cant figure out why It loads the names and everything else perfectly fine, its just those images

What is your exact error? Because this code works just fine:

 [Serializable]
 public class Level
 {
     public string LevelText;
     public int LevelID;
     public int Unlocked;
     public bool IsInteractable;
     public Texture LevelTexture;
     public Button.ButtonClickedEvent OnClickEvent;
 }
 
 public class LevelsController : $$anonymous$$onoBehaviour
 {
     public RawImage Image;
     public Level[] Levels;
 
     protected void Start()
     {
         Image.texture = Level.LevelTexture;
     }
 }

I think your error might be because of this line:

 img = (RawImage)GameObject.Find("Image").GetComponent<RawImage>();

I think what you want to do is this:

 img = newbutton.GetComponentInChildren<RawImage>();

That worked!

Thank you so much!!!

It was the:

  img = (RawImage)GameObject.Find("Image").GetComponent<RawImage>();

That needed to be changed to:

  img = newbutton.GetComponentInChildren<RawImage>();
