Question

I want to open the next world on the basis of the number of stars.

What kind of number of stars can be counted accordingly?

Ok, I get what you want. You should get this done with player prefs, but during gameplay it might be a better idea to just have a starCount int variable.

So, if the PlayerPrefs int already exists, give starCount that value at the start of the scene and every time you collide with a star collider (I’m not sure how you account for collecting stars, but I assume either OnCollisionEnter or OnTriggerEnter is what you are using) add to starCount. When you exit the scene (OnDestroy()) set the levelStarCount to starCount. If you always use this script, it will get/create the unique key for the scene in question:

 int starCount;
 string levelStarCount;
 
 void Start()
 {
 
 levelStarCount = SceneManager.GetActiveScene().name + “StarCount”;
 if(PlayerPrefs.HasKey(levelStarCount))
 {
 starCount = PlayerPrefs.GetInt(levelStarCount);
 }
 else
 {
 starCount = 0;
 }
 }
 
 void OnCollisionEnter(Collider other)
 {
 
 if(other.tag == “Star”)
 {
 starCount = starCount + 1;
 }
 }
 
 void OnDestroy()
 {
 PlayerPrefs.SetInt( levelStarCount, starCount );
 }

I did not test the code, but it should do the trick. Note that this script would need to be attached to the player as when it collides with the game object with the tag “Star” it adds to starCount.

Hope that helps, Cheers

I have this code

 public class LevelSelectScript : $$anonymous$$onoBehaviour {
  private int worldIndex;   
  private int levelIndex;
  //variable which holds the stars obtained   
  private int stars=0;
  
  void  Start (){
   //loop thorugh all the worlds
   for(int i = 1; i <= LockLevel.worlds; i++){
    if(Application.loadedLevelName == "World"+i){
     worldIndex = i;  //save the world index value
     CheckLockedLevels(); //check for the locked levels 
    }
   }
  }
  
  //Level to load on button click. Will be used for Level button click event 
  public void Selectlevel(string worldLevel){
   Application.LoadLevel("Level"+worldLevel); //load the level
  }
  
  //uncomment the below code if you have a main menu scene to navigate to it on clicking escape when in World1 scene
  /*public void  Update (){
   if (Input.Get$$anonymous$$eyDown($$anonymous$$eyCode.Escape) ){
    Application.LoadLevel("$$anonymous$$ain$$anonymous$$enu");
   }   
  }*/
   
  //function to check for the levels locked
  void  CheckLockedLevels (){
   //loop through the levels of a particular world
   for(int j = 1; j < LockLevel.levels; j++){
    //get the number of stars obtained for that particular level
    //used to enable the image which should be displayed in the World1 scene beside the individual levels
    stars = PlayerPrefs.GetInt("level"+worldIndex.ToString() +":" +j.ToString()+"stars");
    levelIndex = (j+1);
    //enable the respective image based on the stars variable value
    GameObject.Find(j+"star"+stars).GetComponent<Image>().enabled = true;
    Debug.Log(j+"-"+stars);
    //check if the level is locked 
    if((PlayerPrefs.GetInt("level"+worldIndex.ToString() +":" +levelIndex.ToString()))==1){    
     //disable the lock object which hides the level button
     GameObject.Find("LockedLevel"+levelIndex).SetActive(false);
    }
     
          Debug.Log(stars);
      
   }
  }
 
 }

It calculates all the stars' amount at the end of a level How can i add all the stars' amount to each other in the end.

The code I gave you above will count the stars during gameplay, you can of course make the string for each level whatever you want. Thereafter when you are in a navigation screen where you select your levels. You can create a variable called totalStars for example and use:

 totalStars = totalStars + PlayerPrefs.GetInt(“levelOneWorldOneStarCount”); //use whatever key you use for the level in question
 totalStars = totalStars + PlayerPrefs.GetInt(“levelTwoWorldOneStarCount”);

Etc... etc..
