Question by Dave 11 · May 23, 2011 at 07:51 PM · guiarrayvariablecomponentvalue

How to get a value from an array within another script.

Ok, so I got a script attached to a gameObject, lets say the name is objectProperties, then I have another script on the mainCamera called theGUI, which also creates my gui that should fetch the variable in an array from the gameobject tagged with 'selected'. So I got the following:

objectProperties:

 private var code : int[];
 code = new int[11];
 
 function Start() {
     for(n = 0; n < 12; n++) {
         code[n] = 0;
     }
 }

theGUI:

 private var code : int[];
 code = new int[11];
 
 function Update() {
     if(gameObject.FindGameObjectWithTag("selected") != null) {
         var objectProperties : GameObject = gameObjectFindGameObjectWithTag("selected");
         for(var n = 0; n < 12; n++) {
             code[n] = objectProperties.GetComponent(objectProperties).code[n];
         }
     }
 }

Now I want it to take the variable from the script objectProperties, attached to the current gameObject with the tag selected, to the script theGUI, attached to the mainCamera. While, I could set the variables from objectProperties, within the GUI, so that's no problem.

You're code variable at objectProperties must be public to be visible from the other script.

 public var code : int[];

Ok, but I still get 3 errors. - BCE0023: No appropriate version of 'UnityEngine.GameObject.GetComponent' for the argument list '(UnityEngine.GameObject)' was found. BCE0020: An instance of type 'UnityEngine.Component' is required to access non static member 'GetComponent'. BCE0049: Expression 'objectProperties.GetComponent(objectProperties).code[0]' cannot be assigned to.
