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;
        }
    }
}
