Pause OnTriggerEnter

Question

I dont understand why this doesn't work. All i am trying to do is pause the game for one sec OnTriggerEnter:

 using UnityEngine;
 using System.Collections;
 
 public class LevelInfo : MonoBehaviour {
 
     public bool pause;
 
     void Update()
     {
         if (pause){
             Time.timeScale = 0;
         }
         if (!pause){
             Time.timeScale = 1;
         }
     }
     
 
     void OnTriggerEnter (Collider col){
         if (col.gameObject.tag == "Player"){
             StartCoroutine(pauseTime());
             print ("Pause in action");
         }
     }
     
     
     IEnumerator pauseTime(){
         pause = true;
         yield return new WaitForSeconds(1f);
         pause = false;
     }
 
 }

Thank you

WaitForSeconds runs at Time.timeScale.

As you set timeScale to 0 it will never stop waiting.

More detail and a couple of solutions can be found here.

Here is an implementation that monitors Time.realtimeSinceStartup:

 using UnityEngine;
 using System.Collections;
 
 public class Pause : MonoBehaviour
 {
     private float pauseUntil;
     private bool paused;
 
     void Update() {
         if (paused) CheckPause();
     }
 
     void OnTriggerEnter(Collider col) {
         if (col.gameObject.tag == "Player") {
             PauseForDuration(1.0f);
         }
     }
 
     void PauseForDuration(float duration) {
         paused = true;
         pauseUntil = Time.realtimeSinceStartup + duration;
         Time.timeScale = 0.0f;
     }
     
     void CheckPause() {
         if (Time.realtimeSinceStartup >= pauseUntil) {
             Time.timeScale = 1.0f;
             paused=false;
         }
     }
 }

That works by itself, but once i put it inside the OntriggerEnter it doesn't seem to work.

I think your code currently has the following behaviour:

In pauseTime():

set pause to true
start waiting for 1 sec

Then in the next Update():

set timeScale to 0

As a result one second of game time will never pass.

Two solutions are available at the question I linked to above.

Please try one of those and tell me how it goes.

The TimeScale make sense Thank you $$anonymous$$elly but that doest explain why this does not work:

 using UnityEngine;
 using System.Collections;
 
 public class LevelInfo : $$anonymous$$onoBehaviour {
 
     void OnTriggerEnter (Collider col)
     {
         if (col.gameObject.tag == "Player")
         {
             Time.timeScale = 0.0000001f;
         }
     }
 }

Are you then calling:

 yield return new WaitForSeconds(0.0000001f);

In this case all i want to do is Pause on trigger Enter. But that is the part that doesn't work.

So on: OnTriggerEnter = Time.timeScale =0 (Doesn't run the timescale)
