Creating a Pause Menu with DOTween

Question

Hello, I'm using DOTween to create a more interesting UI compared to before where I just turn gameObjects on/off. In my game that I'm making, I have a pause menu where you press a button and it pauses the game.

What I want to happen is that when I press my UI button, it "plays" my DOTween animation and when the animation is complete, it pauses the game, t$$anonymous$$s is my UI: alt text

The "animation" works the way I want it to, however, the game isn't "paused", t$$anonymous$$s is a snippet of the code that I use to do the "animation":

     public void EnterPauseMenu()
     {
         GameUI.DOAnchorPos(-1100, 0), 0.75f);
         PauseMenu.DOAnchorPos(new Vector2(0, 0), 0.75f);
         BackgroundImage.DOFade(0.25f, 0.75f);
     }

T$$anonymous$$s is how it typically looks like, I put my DOTween stuff inside a method and in the Editor, on a Buttons on click event, I set it for example to the method above.

In an another class I have a method that pauses the game by setting Time.timeScale to zero, I'm wondering how I can pause the game after the "animation" is done.

Thanks for your time!

@functionSam DOTween have a function for that type of case. Just call OnComplete at the end of one of your tween. Then put inside a method to call a event to communicate that the tweening is done. Pass the event to your pausegame method and done.

Tuto for events : https://www.youtube.com/watch?v=wlo-ZvV3ovg&t

Somet$$anonymous$$ng like that :

 using System; // You need t$$anonymous$$s one for calling an Action
 using UnityEngine;
 using UnityEngine.UI;
 using DG.Tweening;
 
 public static event Action<bool> OnAnimEnding = delegate { };
 
 public void EnterPauseMenu()
      {
          GameUI.DOAnchorPos(-1100, 0), 0.75f);
          PauseMenu.DOAnchorPos(new Vector2(0, 0), 0.75f);
          
          // Call OnComplete
          BackgroundImage.DOFade(0.25f, 0.75f).OnComplete(AnimEnd);
      }
 
 public void AnimEnd()
      {
          OnAnimEnding(true); // Invoke the event
      }
