Controlling new GUI with Var?

Unity Engine
1

Hello all,

I am running multiple OnGUI()s in different scripts and trying to control them with a static var that I have declared only once, in the first script.

If I change this var in a second script, and directly call the var on the first script using:
myScreen.GetComponent(“Welcome_script”).displayFlag1 = 1;
it works fine.

However, just changing the variable in the second script is not enough to be recognised in the other script, even thought the first script is continually being called.

Am I misunderstanding the global nature of static var?

TIA PW

Not sure I quite followed, but the usual way of doing static variables is like so:

A script called “SomeScript”:

static var someVariable = 1;

Another script called something else:

if (SomeScript.someVariable == 1) {print ("It's one!");}

To clarify, I suppose I am asking about the scope of a static variable.

Since OnGUI is called every frame, why can’t a static variable declared as part of this script, but altered in another script, be automatically be “seen” by the first script?

(I understand directly referencing as in
if (SomeScript.someVariable == 1) {print (“It’s one!”);} but I don’t want to manually reference every script that will be dependent on the static variable.)

Is there a better Global variable that is visible to any script?

Thanks, Peter.

I was wondering the same thing :roll:

Since now, the only way i found to refer to another script is to go trough
GameObject.Find(holdingScriptObject)
and
GetComponent(scriptname)

Is there a more direct way to access outside variables or functions?

Static variables can be accessed anywhere, you just need to prefix the variable name with its containing class.
To create the static variable (lets say I want to make my members ID available to any class/script):

public class myGlobalScript : MonoBehaviour
{
    //Static variables used across the application
    public static string MemberLoginID;
}

Then, when I want to access the MemberLoginID variable, I call it (from any class/script) using the following:

//Set the static varible
myGlobalScript.MemberLoginID = "Spongebob";
//Check the static variable
if(myGlobalScript.MemberLoginID =="Spongebob") DoSomeFunction();

EDIT: Loran, you can also setup static references to GameObjects that you use frequently. Something like:

public class myGlobalScript : MonoBehaviour
{
    //Static references to guiObjects
    public GameObject m_GenericMessageBox;//We can change this in the inspector
    public static GameObject GenericMessageBox;//We reference this at runtime
    void Awake()
    {
         GenericMessageBox = m_GenericMessageBox;//Assign what was in the inspector to the static GameObject
    }

You can drop the GameObject.Find() and just use “myGlobalScript.GenericMessageBx” Note that the example is C#. So if you want to access the GO’s script, the method is somewhat different between JS and C#.

Tx shaun for this post. :wink:

But i’m not ‘aware’ with C sharp syntax and i’m still learning about javascript too so i’ll work around knowing now that it’s possible.

Btw, what are the main performances difference and/or abalaties, between all Unity 's scripting languages?

There aren’t really any performance differences between C# and JS, they are both compiled to MSIL anyway. For Unity, JS is probably the easier language to learn, since all the documentation examples use it and from what I remember, accessing a GameObjects script is slightly simpler.
