After Steamworks.net intergration, getting Steam Overlay to pause game

Unity 2018.3.6f1 Personal
AC v1.66.7

Hi there,
I've followed a guide to get Steamworks.net import and working in unity. That's all fine I think and now have a new script in a gameobject in my project. I want the game to pause when the Steam Overlay is activated and unpause when it isn't. This currently isnt working.

On a side note I am using Adventure Creator with Unity, but I suspect that this isn't working because of the rest of the code, not that bit.

Also, I can only test this after the build is uploaded to Steam since the overlay won't open in Unity. Is there a way around this.

Many thanks, I'm not a coder, here is the code:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using Steamworks;
5. using AC;
6.  
7. public class SteamScript : MonoBehaviour
8. {
9.         protected Callback<GameOverlayActivated_t> m_GameOverlayActivated;
10.  
11.     private void OnEnable()
12.     {
13.         if (SteamManager.Initialized)
14.         {
15.             m_GameOverlayActivated = Callback<GameOverlayActivated_t>.Create(OnGameOverlayActivated);
16.         }
17.     }
18.  
19.     private void OnGameOverlayActivated(GameOverlayActivated_t pCallback)
20.     {
21.         if (pCallback.m_bActive != 0)
22.         {
23.             KickStarter.sceneSettings.PauseGame();
24.             KickStarter.TurnOffAC();
25.             Debug.Log("Steam Overlay has been activated");
26.             Time.timeScale = 0;
27.         }
28.         else
29.         {
30.             KickStarter.sceneSettings.UnpauseGame(1f);
31.             KickStarter.TurnOnAC();
32.             Debug.Log("Steam Overlay has been closed");
33.             Time.timeScale = 1;
34.         }
35.     }
36.  
37.     // Start is called before the first frame update
38.     void Start()
39.     {
40.         if (SteamManager.Initialized)
41.         {
42.             string name = SteamFriends.GetPersonaName();
43.             Debug.Log(name);
44.         }
45.     }
46.  
47.     // Update is called once per frame
48.     void Update()
49.     {
50.      
51.     }
52. }

 

In case anyone else finds this later like I did in 2023: you need to make sure SteamAPI.RunCallbacks(); is being called every update from somewhere. Steamworks.net takes care of this for you in its Update if you have a persistent GameObject.
