Question by Skalde · May 14, 2013 at 07:54 AM · errorcrashcallreport

You are not allowed to call this function when declaring a variable

Hello Unity Community, i have an Error that messes my builded game up with a report message, so heres the error i'v got:

UnityException: You are not allowed to call this function when declaring a variable. Move it to the line after without a variable declaration. If you are using C# don't use this function in the constructor or field initializers, Instead move initialization to the Awake or Start function. Pause Controller..ctor () (at Assets/Scripts/Pause Controller.js:2)

and heres the script the error comes from:

 var menuHeight:float=500;
 var menuWidth:float=500;
 var buttonSpacing:float=25;
 var mainMenu: String = "MainMenu";
 var titleTexture:Texture2D;
 var customSkin:GUISkin;
 var customStyle:GUIStyle;
 var Player: MouseLook = GetComponent(MouseLook);
 var MainCamera: MouseLook = GetComponent(MouseLook);
 
 function OnGUI(){
     GUI.skin = customSkin;
     GUILayout.BeginArea(Rect(Screen.width/2-menuWidth/2,Screen.height/2-menuHeight/2,menuHeight,menuWidth),customStyle);
     GUILayout.Space(50);
     GUILayout.Label(titleTexture);
     GUILayout.Space(buttonSpacing);
     Time.timeScale=0;
     Screen.showCursor = true;
     Player.GetComponent(MouseLook).enabled = false;
     MainCamera.GetComponent(MouseLook).enabled = false;
     if(GUILayout.Button("Resume Game")){
         gameObject.GetComponent(PauseMenu).enabled = false;
         Time.timeScale=1;
         Screen.showCursor = false;
         Player.GetComponent(MouseLook).enabled = true;
         MainCamera.GetComponent(MouseLook).enabled = true;
     }
     GUILayout.Space(buttonSpacing);
     if(GUILayout.Button("Exit to Desktop")){
         Application.Quit();
     }
     GUILayout.Space(buttonSpacing);
     GUILayout.EndArea();
 }

i really hope to get this thing solved. thanks in advance ^^

Replace those two lines:

 var Player: MouseLook = GetComponent(MouseLook);
 var MainCamera: MouseLook = GetComponent(MouseLook);

with those:

 var Player: MouseLook;
 var MainCamera: MouseLook;
 function Start()
 {
     Player = GetComponent(MouseLook);
     MainCamera = Player;
 }

Also you don't need to get the component again and again. In OnGUI just do

 Player.enabled = false;

btw what's the point of having two variables holding the same component? It seems you set them both at the same time which makes zero sense.

I guess you simply should remove all GetComponent calls and assign your references in the inspector.

actually i just solved it myself by changing the 2 variables to something like this: var Player : GameObject; and the same for the camera and now it works fine, but thanksfor your effort ^^
