Need Help Accessing scripts from other scenes.

Unity Engine

I need to be able to access the isInteraction 1,2,3 and 4 from the dialog manager and the hasBeenToScene 1,2,3 and 4 from my playerController but they are being used in differant scenes. How can i do that

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;

public class PlayerController : MonoBehaviour {

    public float moveSpeed;
    public float jumpForce;
    public float speedMultiplier;
    private float moveSpeedStore;

    public float speedIncreaseMilstone;
    private float speedIncreaseMilestoneStore;
    private float speedMilestoneCount;
    private float  speedMilestoneCountStore;

    public GameManager theGameManager;

    public float jumpTime;
    private float jumpTimeCounter;

    public bool hasBeenToScene1;
    public  bool hasBeenToScene2;
    public  bool hasBeenToScene3;
    public  bool hasBeenToScene4;
    private bool stoppedJumping;
    public bool canDoubleJump;

    public ScoreManager scoreManager;

    // Use this for initialization

You probably want to make them a singleton. Then they can be accessed in any scene, but they won’t create duplicates.

The player, though, I would move that information to a game manager, and maybe the dialogue information also, or you can have multiple managers on one empty game object that are singletons.

This can be easily achieved using static classes:

Public static class DialogueManager
{
public static bool isInteraction1 = false;
public static bool isInteraction2 = false;
public static bool isInteraction3 = false;
public static bool isInteraction4 = false;
}

Make sure you save this in the Assets Folder. This script cannot be put on any gameobject but you can access the variables from any scene and even change their values.

Cheers!

This is the simplest solution if you’re unfamiliar with the singleton approach.
Formatted for your viewing…

Public static class DialogueManager {
    public static bool isInteraction1 = false;
    public static bool isInteraction2 = false;
    public static bool isInteraction3 = false;
    public static bool isInteraction4 = false;
}

It would be an idea to add a handful of helper methods to do things such as resetting all the interactions etc.
