Accessing Variables from other scripts

Question

I'm kind of a programming noob, but my knowledge should be good enough to get this simple game I'm trying to make done.

So my question is that I have a pause menu, a GUI appears and I want to be able to click a button and things will happen.

When you press escape, the game pauses just fine, and when you press escape it un-pauses. I also want to be able to click the continue button to un-pause the game.

I have a script for the continue button that references the "Is paused" paused variable and i want to set it to false, like this:

 function OnMouseDown ()
 {
 
     GameObject.Find("Main Camera").GetComponent(Pause).pauseGame = false;
 }

but it doesn't seem to be working.

Here is the script for my pause interface:

 public var pauseGame : boolean = false; //the variable I'm trying to access
 public var showGUI : boolean = false;
 public var optionsMenu : boolean = false; 
 
 
 function Start() 
 {
     Screen.lockCursor = true;
 }
 
 function Update () 
 {
 
     if(Input.GetKeyDown(KeyCode.Escape))
     {
     
         pauseGame = !pauseGame;
         
         if(pauseGame == true)
         {
             Time.timeScale = 0;
             pauseGame = true;
             GameObject.Find("Main Camera").GetComponent (MouseLook).enabled = false;
             GameObject.Find("Main Camera").GetComponent (ColorCorrectionCurves).enabled = true;
             GameObject.Find("Main Camera").GetComponent (NoiseAndGrain).enabled = true;
             GameObject.Find("First Person Controller").GetComponent (MouseLook).enabled = false;
             GameObject.Find("Crosshair").GetComponent(GUITexture).enabled = false;
             Screen.lockCursor = false;
             showGUI = true;
         }
         else if(pauseGame == false)
         {
             Time.timeScale = 1;
             pauseGame = false;
             Screen.lockCursor = true; //Not relocking!
             GameObject.Find("Main Camera").GetComponent (MouseLook).enabled = true;
             GameObject.Find("Main Camera").GetComponent (ColorCorrectionCurves).enabled = false;
             GameObject.Find("Main Camera").GetComponent (NoiseAndGrain).enabled = false;
             GameObject.Find("First Person Controller").GetComponent (MouseLook).enabled = true;
             GameObject.Find("Crosshair").GetComponent(GUITexture).enabled = true;
             showGUI = false;
         }
     }
 }

If anyone can help me that would be wonderful!

ALSO: I'm having trouble with my mouse lock command. The mouse unlocks just fine when I go to pause, but it doesn't relock when I un-pause the game, and I need it to go back to being hidden and locked.

You could try setting it up as a function...

 function Update ()
 {
     if(Input.GetKeyDown(KeyCode.Escape))
     {
         pauseGame = !pauseGame;
         PauseGame(pauseGame);
     }
 }
 
 public function PauseGame(should : boolean)
 {
     if(should){
         Time.timeScale = 0;
         pauseGame = true; // this is not needed as weve already stated pauseGame was true under Input.GetKeyDown
         GameObject.Find("Main Camera").GetComponent (MouseLook).enabled = false;
         GameObject.Find("Main Camera").GetComponent (ColorCorrectionCurves).enabled = true;
         GameObject.Find("Main Camera").GetComponent (NoiseAndGrain).enabled = true;
         GameObject.Find("First Person Controller").GetComponent (MouseLook).enabled = false;
         GameObject.Find("Crosshair").GetComponent(GUITexture).enabled = false;
         Screen.lockCursor = false;
         showGUI = true;
     }else{
         Time.timeScale = 1;
         pauseGame = false; // this is not needed as weve already stated pauseGame was false under Input.GetKeyDown
         Screen.lockCursor = true; 
         GameObject.Find("Main Camera").GetComponent (MouseLook).enabled = true;
         GameObject.Find("Main Camera").GetComponent (ColorCorrectionCurves).enabled = false;
         GameObject.Find("Main Camera").GetComponent (NoiseAndGrain).enabled = false;
         GameObject.Find("First Person Controller").GetComponent (MouseLook).enabled = true;
         GameObject.Find("Crosshair").GetComponent(GUITexture).enabled = true;
         showGUI = false;    
     }
 }

And your other script could be something like...

 pauseScript.PauseGame(false); // pauseScript is a reference to the above script. you will need to set that up

ALso, why not set up a variable for your main camera so you dont have to always "Find" it. Find is expensive, especially because you are searching by name.

I'm not familiar with javascript but I think everything above is correct

I found a great thread that may help you out : http://forum.unity3d.com/threads/newbie-guide-to-unity-javascript-long.34015/

As for the screen locking goes, I am not sure. I have never tried to lock the mouse to the screen. I would start: http://docs.unity3d.com/ScriptReference/Screen-lockCursor.html
