Calling a variable from a different script
I've seen a few answers but no matter what I try I get no lucky
// Create an object of main menu
public MainMenu mainMenu;
public int gEnzyme;
From the MainMenu script I want to call a variable called enzyme of type int
Within the OnGUI function I assign the variable to the MainMenu variable:
gEnzyme = mainMenu.enzyme;
I've done this as I am trying to display the integer within a Box using '.ToString()'.
GUI.Box (new Rect(0, 300, 100, 50), enzyme.ToString());
I've tried all different ways of trying this even ones I feel are pointless just to see.
I've probably made a rookie error somewhere
The error I keep getting is:
NullReferenceException: Object reference not set to an instance of an object Game.OnGUI ()
Thank you in advance!
gEnzyme.ToString() perhaps.
I assume you are calling enzyme.ToString() in a class outside of the mainmenu class.
Ignore the enzyme.ToString() forgot to repost the updated one. It does actually say gEnzyme.ToString(), but still doesn't work.
If they are on the same object simply use GetComponent(Scriptname).variable.
If not on the same object, Find the object with GameObject.Find or FindWithTag and then use GetComponent.
Something like :
objectInstance = GameObject.Find("menuObject"); //find and store mainmenu gameobject
variableInstance = objectInstance.GetComponent(MainMenu).gEnzyme; //access variable in script on that objects's newly created instance
These are in JS, you would need the C# equivalents, which you can find in the scripting reference (or here)
