Changing Scenes Efficiently

Question

I am making a game, and it has around 32 levels. i have a scene which has a button, with the number level, eg a button with 1, and so on. at the moment i have a Script which loads the scene if the button is pressed, but having to write out 32 different voids going between each scene is a real hassle, is there a way i could do this better? This is the script that is for the buttons: using UnityEngine; using UnityEngine.SceneManagement;

 public class GameMaster : MonoBehaviour
 {
     public void GoToGameScene()
     {
         SceneManager.LoadScene("Level01");
     }
 
     public void Restart()
     {
         SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex);
     }
     
     public void GoToMainMenu()
     {
         SceneManager.LoadScene("MainMenu");
     }
 
     public void LevelSelect()
     {
         SceneManager.LoadScene("LevelSelect");
     }
 }

the level select void is the scene with all the buttons. this is what it looks like alt text

i know it doesnt look the best, but its for testing purposes

I am not sure if this is the best but create a function that gets the number from each button, something like:

 string number;
 
 public void getNumber()
 {
      number = gameObject.GetComponent<Text>().text;
  }

and then make a function to load the level while referencing your number level

    public void ChangeLevel()
     {
         SceneManager.LoadScene(number);
     }

you need to change a bit the string, right ? Like

 string number;
  
  public void getNumber()
  {
       number = "Level"+(gameObject.GetComponent<Text>().text);
   }

Because @Symbie seems to use a nomenclature like "level" + level's number

In any case, "number" must be equals to targeted scene's name

I suggest that you use build index. Press build settings and add all your scenes in order and they will have a build index. Never use strings in scene management. Here is a link to that: https://docs.unity3d.com/ScriptReference/SceneManagement.Scene-buildIndex.html

Next, you should assign the function to each and every button with a Button parameter and just take the button's text convert it to a number and load the level with build indexes accordingly.
