Can't set Time.timeScale back to 1.

Question

I am trying to make a platform runner in 3D and wanted to be able to pause the game when the user pressed "P". I was able to do this but now I'm having a problem with resuming the game. I tried setting the Time.timeScale back to 1, but it didn't work. I'm using this code: using UnityEngine;

 public class PlayerMovement : MonoBehaviour
 {
 public bool paused = false;
 void Pause()
     {
         Time.timeScale = 0;
     }
     void Update()
     {
         if(Input.GetKey("p")) 
         {
             if(paused == false)
             {
                 Pause();
             }else
             {
                 paused = false;
                 Time.timeScale = 1;
             }
         }
         while(paused)
         {
             Pause();
         }
     }
 }

I have tried to disable the forces on the Rigidbody, but I had the same problem.

I hope someone can help me and thanks in advance.

Try this simple code, use P for pause and resume both:

    bool pause = false;
     void Update(){
      if(Input.GetKeyDown(KeyCode.P)){
               pause = !pause;
             if(pause){
                 Time.timescale = 0;
             }else if(!pause){
                Time.timescale = 1;
              }
          }
        }

First: You never set paused to true. So it never goes into the else clause at line 15.

Solution: set paused to true in your Pause() function.

Second: once you have code that sets pausedto true, you need to remove the while block at lines 21-24 entirely, because

a) it's pointless - you only need to call Pause() once

and

b) it's an infinite loop that will make Unity hang and currently you're only getting away with it because you never set paused to true
