Pause Menu

Question

I have this script that pauses the game, but I can still look around and shoot. I am using the First Person Controller.

Pause menu code:

 var gamePaused : boolean = false;
 
 function Update () {
 
  if(Input.GetKeyDown(KeyCode.Escape)){
  if(gamePaused){
 
  Time.timeScale=1.0;
  gamePaused = false;
 
  }else{
 
  Time.timeScale = 0.0;
  gamePaused = true;
  }
  }
 
 }
 
 function OnGUI(){
 
  if(gamePaused){
  if(GUI.Button(Rect (450, 100, 100, 30), "Resume")){
  Time.timeScale = 1.0;
  gamePaused = false;
  }
  if(GUI.Button(Rect(450, 140, 100, 30), "Main Menu")){
  Application.LoadLevel("Menu");
  }
  if(GUI.Button(Rect(450, 180, 100, 30), "Options")){
  }
  if(GUI.Button(Rect(450, 220, 100, 30), "Quit")){
  Application.Quit();
     }
  }
 }

My question is how can I completely pause the game. Stop looking around and stop shooting.

Thank you.

Hi there,

Well, Time.timescale only affects time-based functions.

Simplest solution:

Since Time.timeScale is a global var, add this to your control scripts:

 if (Time.timeScale != 0){
 
 }

Or: (EDIT: worse, because with FixedUpdate() you could miss some inputs)

Include the controls in a time-based function like fixedUpdate() or Update() with Time.deltaTime

C#

 void FixedUpdate(){
   if (Input.GetKeyDown("space")){
     Shoot();
   }
 }

Hope this helps...

EDIT: Just as Fafase said, it's better just to use Time.deltaTime so that it becomes time-dependent. (btw sometimes you need you controls to behave the same way while in slow motion... So I don't think it's as "useless" as Fafase said.)

I add that to what script? The First Person Controller or $$anonymous$$ouseLook?

Well, in the $$anonymous$$ouseLook script you can probable add these lines in the Update function

void Update(){

if (Time.timeScale != 0){ ...original blahblah... }

}

It didn't worked. I can still look around. What am I doing wrong?

can you post the $$anonymous$$ouseLook code?

"Include the controls in a time-based function like fixedUpdate"

FixedUpdate is only ment for physics based calculations. Never use event functions like Input.Get$$anonymous$$eyDown in FixedUpdate. It will probably fail. FixedUpdate is not necessarily called each frame, so a $$anonymous$$eydown can be missed totally or even processed multiple times.

The usual approach is to disable scripts that should be deactivated.

Try this update function in your MouseLook Script

 void Update () { 
     if (Time.timeScale != 0){
         if (axes == RotationAxes.MouseXAndY) { 
             float rotationX = transform.localEulerAngles.y + Input.GetAxis("Mouse X") * sensitivityX;
             rotationY += Input.GetAxis("Mouse Y") * sensitivityY; rotationY = Mathf.Clamp (rotationY, minimumY, maximumY);
             transform.localEulerAngles = new Vector3(-rotationY, rotationX, 0); 
         }
         else if (axes == RotationAxes.MouseX) { 
             transform.Rotate(0, Input.GetAxis("Mouse X") * sensitivityX, 0); 
         }
         else {
             rotationY += Input.GetAxis("Mouse Y") * sensitivityY; rotationY = Mathf.Clamp (rotationY, minimumY, maximumY);
             transform.localEulerAngles = new Vector3(-rotationY, transform.localEulerAngles.y, 0); 
         }
     }
 }

This is simply useless!!! Why would alter Time.timeScale if you simply need a boolean variable? Your

 if (Time.timeScale != 0)

is just as good as

 if(anyBoolean)

now the difference is the amount of cycles required for your version and the simple version.

if you do not have any Time.deltaTime or FixedUpdate, do not bother using Time.timeScale.

Also, what is shown above and to which you gave a +1 is only stopping this script but all others will continue until you place the if statement. That involves you have to add an if statement that is checked on every single script on every single frame.

If you add to all inputs and movements a Time.deltaTime, you make your game machine independant, that means your game will run the same speed on any computer. At the moment, your game will walk on a Pentium 4 and run on a I7. Then, when setting Time.timeScale to 0, nothing will move (GUI is still activated though) until set back to 1.

Trust me the solution above is not fixing your issue in the most efficient and easiest way.

So how can I implement what are you saying?

Here's my Pause Menu Script, feel free to use it, just make sure you replace any GUI Textures with your own.
