Access Array From Another Script?

Questions & Answers
1

Hey guys, so I’m trying to use an Array to circumvent creating an actual server for login information since the program I’m making if for home use, I see no point in a PHP. Anyway so far what I have is this.

First Script:

//Strings
var firstName : String = String.Empty;
var lastName : String = String.Empty;
var desiredUser : String = String.Empty;
var desiredPass : String = String.Empty;
var confirmPass : String = String.Empty;

//Arrays
var registeredUsers : Array = [];

//Booleans
var passwordIsSame : boolean = false;
var userNameChosen : boolean = false;
var displayMessage : boolean = false;

//floats
var displayTime : float = 3;

function Start () {

}

function Update ()
{
if (displayMessage)
displayTime -= Time.deltaTime;

if(displayTime <= 0.0)
displayMessage = false;



if(desiredUser.length > 0 && desiredUser.length <= 15)
userNameChosen = true;


}

function OnGUI ()
{
	//If Statements
	if(displayMessage)
	{
		GUI.Label(new Rect (Screen.width/ 2 - 110, Screen.height/ 2 + 145, 500, 500), "Some information has not properly been filled in.");
	}
	
	//Labels
	GUI.Label(new Rect(Screen.width/ 2 - 57, Screen.height/ 2 - 23, 200, 200), "Please Register an Account.");
	GUI.Label(new Rect(Screen.width/ 2 - 120, Screen.height/ 2, 200, 200), "First Name:");
	GUI.Label(new Rect(Screen.width/ 2 - 119, Screen.height/ 2 + 23, 200, 200), "Last Name:");
	GUI.Label(new Rect(Screen.width/ 2 - 164, Screen.height/ 2 + 46, 200, 200), "Desired Username:");
	GUI.Label(new Rect(Screen.width/ 2 - 161, Screen.height/ 2 + 69, 200, 200), "Desired Password:");
	GUI.Label(new Rect(Screen.width/ 2 + 103, Screen.height/ 2 + 46, 200, 200), "(Limit of 15 characters.)");
	GUI.Label(new Rect(Screen.width/ 2 + 103, Screen.height/ 2 + 69, 200, 200), "(Limit of 25 characters.)");
	GUI.Label(new Rect(Screen.width/ 2 - 162, Screen.height/ 2 + 92, 200, 200), "Confirm Password:");
	
	//TextFields
	firstName = GUI.TextField(Rect(Screen.width/ 2 - 50, Screen.height/ 2, 150, 20), firstName, 99);
	lastName = GUI.TextField(Rect(Screen.width/ 2 - 50, Screen.height/ 2 + 23, 150, 20), lastName, 99);
	desiredUser = GUI.TextField(Rect(Screen.width/ 2 - 50, Screen.height/ 2 + 46, 150, 20), desiredUser, 15);
	desiredPass = GUI.PasswordField(Rect(Screen.width/ 2 - 50, Screen.height/ 2 + 69, 150, 20), desiredPass, "*"[0], 25);
	confirmPass = GUI.PasswordField(Rect(Screen.width/ 2 - 50, Screen.height/ 2 + 92, 150, 20), confirmPass, "*"[0], 25);
	
	//GUI Buttons
	if(GUI.Button(Rect(Screen.width/ 2 - 28, Screen.height/ 2 + 115, 100, 30), "Register"))
	{
		if(desiredPass.length > 0)
			{	
				if(desiredPass == confirmPass)
					{
						passwordIsSame = true;
					}
			}	
		if(passwordIsSame && userNameChosen)
			{
				registeredUsers.Push (desiredUser);
				for (var value : String in registeredUsers)
					{
						print(value);
					}
				Application.LoadLevel("Login");				
			}
		if(!passwordIsSame || !userNameChosen)
			{
				displayMessage = true;
				displayTime = 3.0;
			}	
	}
	
}

That is used in a different scene which is for registering an account. It works too. The username you choose is pushed into the array. The thing is I want to access it in the other scene at the Login menu so it can check if the user matches what is stored in the array.

Here’s the second script:

var userToEdit : String = String.Empty;
var passToEdit : String = String.Empty;
var gameObjectArray : GameObject[] = GameObject.FindWithTag("arrayObject").GetComponent("RegistrationScript").registeredUsers;

function Start () {

}

function Update () 
{

}

function OnGUI ()
{
	//Aestetics
	GUI.Label(new Rect(Screen.width / 2 - 117, Screen.height / 2 + 13, 150, 20), "Password:");
	GUI.Label(new Rect(Screen.width / 2 - 120, Screen.height / 2 - 10, 150, 20), "Username:");
	GUI.Label(new Rect(Screen.width / 2 - 100, Screen.height / 2 - 40, 500, 500), "Please Enter Your Username and Password.");
	userToEdit = GUI.TextField(Rect(Screen.width / 2 - 50, Screen.height / 2 -10, 150, 20), userToEdit, 25);
	passToEdit = GUI.PasswordField(Rect(Screen.width / 2 - 50, Screen.height / 2 + 13, 150, 20), passToEdit, "*"[0], 25);
	
	//Buttons and Functionallity
	if(GUI.Button(Rect(Screen.width / 2 + 30, Screen.height / 2 + 35, 100, 30), "Register"))
		{
			Application.LoadLevel("Registration");
		}
	
	if(GUI.Button(Rect(Screen.width / 2 -80, Screen.height / 2 + 35, 100, 30), "Login"))
		{
		
		}
}

What I want to do is at the bottom where the final button is i want to create an if statement that will ask
if(userToEdit == ‘any username stored in the database’)
Debug.Log(“This works.”)

Or something like that for confirmation so I can focus on optimizing it next.

Any help would be greatly appreciated.

to read the array most effectively, what you should do is create a script with a class inside it that holds the data for the array, then use that class as a reference for an array:

var MyArray : ArrayClass;

//separate script named ArrayClass

class ArrayClass {
//stuff you want to have for the array
}

what this will do is let you use that same class for multiple arrays so you can have the data directly transfer: ThisScript.MyArray1[0] = ThatScript.MyArray2[0];

First, make sure the array is public.
What I do is always this.

private PlayerController player;

void Start () {
		player = GameObject.Find("PlayerObjectName").GetComponent<PlayerController>();
	}

Then I can always use the public variables/functions by eg. player.speed = 0;

Sorry for the C#. Also, I don’t know if it will work when the scripts are from two different scenes.
