Hello everyone. Im still a newb on using unity. 
So the problem I present today is this: I ask the PlayerPrefs if the user is a first timer, if so ask him his name.
What I don’t really know how to solve this is the next.
I’ve created a couple of scripts but I don’t know what to attach them too. If I want to load up first before main menu then my assumption would be:
Creating an empty scene just to load everything up and create a script called loadup, which loads up user’s profile settings. If its the user’s first time then continue to main menu. So, I thought I had it right but here’s what happens. I added a script called loadup and attached it to the MainCamera with this:
LoadStartup.cs
public class LoadStartup : MonoBehaviour {
//#pragma strict
private int PlayedBefore;
private string textInput;
private string textInputHeader;
void Awake ()
{
PlayedBefore = PlayerPrefs.GetInt("FirstTimer");
Debug.Log("Awaking, so PlayedBefore = " + PlayedBefore);
// Checks if this is the first time you play
if(PlayedBefore == 0) {
//First Time playing, so we set 'PlayeBefore to 'True'
Debug.Log ("First Timer");
/*PlayedBefore = 1;
PlayerPrefs.SetInt("FirstTimer", (PlayedBefore)); */
// Checking the values
Debug.Log("PlayedBefore = " + PlayedBefore);
} else {
// Else we already played, continue to next scene or something.
Debug.Log ("You've Already Played");
Debug.Log("PlayedBefore = " + PlayedBefore);
}
}
All goes well until here. it does check if the user is a first timer.
But here, is the real deal.
And where my question goes a long way. as OnGUI is called constantly, I wouldn’t seem fit to add the inputbox here but I had a compiler error saying “You can only call GUI functions on a OnGUI method” or something like that.
And furthermore, I get an error on the line where it says" textInput = GUI.TextInput…"
Here’s the error: NullReferenceException: Object not sent to an instance of an object"
Here’s the OnGUI method
/* Here goes onGui things. Test ask user name */
void OnGUI ()
{
if (PlayedBefore == 0)
{
Debug.Log ("First timer, Adding Questions");
textInputHeader = "Enter your Name:";
textInput = GUI.TextField (new Rect (Screen.width * 0.5f, Screen.height * 0.85f, Screen.width * 0.25f, Screen.height * 0.1f),textInput, 25);
} else if (PlayedBefore == 1)
{
GUI.Label (new Rect(Screen.width * 0.5f, Screen.height * 0.85f, Screen.width * 0.25f, Screen.height * 0.1f), "Welcome "+ textInput);
}
}
}
Thanks for your time reviewing this question. If you could explain to me why its happening(error) and what would be your personal solution to my objective.(which would be adding a small box asking the user its name.(Instead of using OnGUI)
Have an awesome day! Just like you people are!
