SCRIPT DO GAME CONTROLLER

Código:

using UnityEngine;
using System.Collections;

public class GameController : MonoBehaviour {

 private bool isPaused = false;
 private bool callPause = false;
 private bool callUnPause = false;
 
 public AudioSource playerSound;
 public AudioSource soundIn;
 public AudioSource soundOut;
 
 private AudioSource[] audiosGame;
 
 // Use this for initialization
 void Start () {
 
 audiosGame = FindObjectsOfType(typeof(AudioSource)) as AudioSource[];
 
 foreach(AudioSource tempAudio in audiosGame){
 tempAudio.volume = PlayerPrefs.GetFloat("CurrentVolume");
 }
 
 
 }
 
 // Update is called once per frame
 void Update () {
 if (callPause) {
 callPause = false;
 isPaused = true;
 Time.timeScale = 0;
 
 playerSound.Stop ();
 soundIn.volume = 0;
 soundOut.volume = 0;
 
 }
 
 if (callUnPause) {
 callUnPause = false;
 isPaused = false;
 Time.timeScale = 1;
 
 soundIn.volume = PlayerPrefs.GetFloat ("CurrentVolume");
 ;
 soundOut.volume = PlayerPrefs.GetFloat ("CurrentVolume");
 ;
 }
 


 }
 
 public void PauseGame(){
 if(isPaused){
 callUnPause = true;
 }
 else{
 callPause = true;
 }
 }
 
 public bool IsPausedGame(){
 return isPaused;
 }
}


SCRIPT DO HUD DO PAUSE:

Código:

using UnityEngine;
using System.Collections;

public class HUDGameController : MonoBehaviour {
 
 private GameController gameController;
 
 public Texture backGroundPause;
 public GUISkin guiSkinToUse;
 
 // Use this for initialization
 void Start () {
 gameController = FindObjectOfType(typeof(GameController)) as GameController;
 }
 
 // Update is called once per frame
 private void Update () {
 if(Input.GetKeyDown(KeyCode.Escape)){
 gameController.PauseGame();
 }
 
 
 }
 
 void OnGUI(){
 GUI.skin = guiSkinToUse;
 if(gameController.IsPausedGame()){
 Update();
 GUI.DrawTexture(new Rect(0,0, Screen.width, Screen.height), backGroundPause);
 
 GUILayout.BeginArea(new Rect(Screen.width/2-150, Screen.height-(0.8f*Screen.height), 300, Screen.height));
 if(GUILayout.Button("Resume Game")) gameController.PauseGame();
 GUILayout.Space(10);
 if(GUILayout.Button("Exit To Menu")){
 gameController.PauseGame();
 Application.LoadLevel("MainMenu");
 }
 GUILayout.EndArea();
 
 
 }
 
 
 }
 

Tinha alguns errinhos... Tenta ver agora:

Código:

using UnityEngine;
using System.Collections;

public class HUDGameController : MonoBehaviour {
   
   private GameController gameController;
   public Texture backGroundPause;
   public GUISkin guiSkinToUse;

   void Start () {
      gameController = FindObjectOfType(typeof(GameController)) as GameController;
   }

   private void Update () {
      if(Input.GetKeyDown(KeyCode.Escape)){
         gameController.PauseGame();
      }   
   }
   
   void OnGUI(){
      GUI.skin = guiSkinToUse;
      if(gameController.IsPausedGame()){

         GUI.DrawTexture(new Rect(0,0, Screen.width, Screen.height), backGroundPause);
         
         GUILayout.BeginArea(new Rect(Screen.width/2-150, Screen.height-(0.8f*Screen.height), 300, Screen.height));
         if(GUILayout.Button("Resume Game")){
            gameController.PauseGame();
         }
         GUILayout.Space(10);
         if(GUILayout.Button("Exit To Menu")){
            gameController.PauseGame();
            Application.LoadLevel("MainMenu");
         }
         GUILayout.EndArea();
      }   
   }
}

e

Código:

using UnityEngine;
using System.Collections;

public class GameController : MonoBehaviour {
   
   private bool isPaused = false;
   private bool callPause = false;
   private bool callUnPause = false;
   public AudioSource playerSound;
   public AudioSource soundIn;
   public AudioSource soundOut;
   
   private AudioSource[] audiosGame;

   void Start () {
      audiosGame = FindObjectsOfType(typeof(AudioSource)) as AudioSource[];
      foreach(AudioSource tempAudio in audiosGame){
         tempAudio.volume = PlayerPrefs.GetFloat("CurrentVolume");
      }
   }

   void Update () {
      if (callPause) {
         callPause = false;
         isPaused = true;
         Time.timeScale = 0;
         playerSound.Stop ();
         soundIn.volume = 0;
         soundOut.volume = 0;
      }
      if (callUnPause) {
         callUnPause = false;
         isPaused = false;
         Time.timeScale = 1;
         soundIn.volume = PlayerPrefs.GetFloat ("CurrentVolume");
         soundOut.volume = PlayerPrefs.GetFloat ("CurrentVolume");
      }
   }
   
   public void PauseGame(){
      if(isPaused){
         callUnPause = true;
      }
      else{
         callPause = true;
      }
   }
   
   public bool IsPausedGame(){
      return isPaused;
   }
}
