do something if a method cant be executed
Hi :)
so basically here I don't want my player to load its game if there is no save to load. I'm using simple json to save and load infos about the character.
In my menu I also want a pop up to display whenever a save cant be reached.
Ive tried some do while but as i cant go further than the line where it says "LoadAllInformation()" well I'd like to know if there's a way to check for certain file ? or even if in case of the failure of the execution of a method to execute some code ? thank you !
using UnityEngine;
using UnityEngine.SceneManagement;
public class MainMenu : MonoBehaviour
{
public GameObject ErrorLoad_Panel;
private void Start()
{
ErrorLoad_Panel.SetActive(false);
}
public void PlayGameButton()
{
SceneManager.LoadScene("RaceSelection");
}
public void LoadGameButton()
{
GameController.LoadAllInformation();
SceneManager.LoadScene("MainWorld");
// if cant load then do this
ErrorLoad_Panel.SetActive(true);
}
public void QuitGameButton()
{
Application.Quit();
}
public void ErrorLoadButton()
{
ErrorLoad_Panel.SetActive(false);
}
}
You should have your LoadAllInformation() return a bool depending on weather you loaded or not. To determine that, you should usually check if a file exists before trying to read from it. An example:
public bool LoadGameData()
{
string filePath = @"\saves\character.json";
if(File.Exists(filePath))
{
string dataAsJson = File.ReadAllText(filePath);
GameData loadedData = JsonUtility.FromJson<GameData>(dataAsJson);
}
else
{
// No save file
return false;
}
return true;
}
