Last time I asked you about how to freeze time when opening inventory and maps, I had some questions. My map would remain there after it was opened and could not be closed. Can you give me some advice? The article I was recommended to refer to last time

Here are my steps

1. Add in GameManager.cs

<code>    [SerializeField] private FadeUI mapPause;

if(Input.GetButtonDown("Map") && PlayerController.Instance.openMap)
        {
            mapPause.FadeUIIn(fadeTime);
            Time.timeScale = 0;
            GameManager.Instance.gameIsPaused = true;
        }
        else if (Input.GetButtonDown("Map") && !PlayerController.Instance.openMap)
        {
            mapPause.FadeUIOut(fadeTime);
            UnpauseGame();
        }</code>

2. Add FadeUI.cs & Canvas Group to Unity MapHandler

3. Drag MapHandler into GameManager’s mapPause in Unity

Let’s try this addition of code:

        if(Input.GetButtonDown("Map") && PlayerController.Instance.openMap && !GameManager.Instance.gameIsPaused)
        {
            mapPause.FadeUIIn(fadeTime);
            Time.timeScale = 0;
            GameManager.Instance.gameIsPaused = true;
        }
        else if (Input.GetButtonDown("Map") && !PlayerController.Instance.openMap && GameManager.Instance.gameIsPaused)
        {
            mapPause.FadeUIOut(fadeTime);
            UnpauseGame();
        }

it doesn’t work, I made the above modifications, but it will freeze completely and become inoperable.

Okay remove that code, I want to check something, do you still have your input for the Map button in the PlayerController.cs?

Furthermore, can you show how your map looks like in the Scene’s Hierarchy?

Considering what it is, i believe the map is on 24/7 and PlayerController.Instance.openMap may be set to true without being set false one way or the other.

Okay, my PlayerController has input for the map button, and this is my video. In the video, I keep clicking the map button. I guess it tries to close?

        if(Input.GetButtonDown("Map") && !PlayerController.Instance.openMap)
        {
            mapPause.FadeUIIn(fadeTime);
            Time.timeScale = 0;
            GameManager.Instance.gameIsPaused = true;
        }
        else if (Input.GetButtonDown("Map") && !PlayerController.Instance.openMap)
        {
            mapPause.FadeUIOut(fadeTime);
            UnpauseGame();
        }

Can you try this?

I made the above modifications. After I press the map button for the first time, it will disappear by itself. After pressing the button again, an error message will be generated.

Mhm, I would likely believe that the issue behind this is caused by there being two codes searching for the map input, where one of them is dependent on the openMap bool that’s activated by the other.

In other words, I believe it’ll be best if you compile all the related code for turning the map on and off into one script. Which would probably be better in the GameManager.cs.

Can you try moving the code for activating openMap in PlayerController.cs into the code you use in GameManager.cs?

I think I have a big problem, I can’t pause the game while I’m porting the switch map to GameManager, but I decided to finish the switch map first, and then make the time freeze, but after I port the code to GameManager my map Something went wrong, it was completely invisible, I couldn’t even see the map from the Scene screen, and the SceneTransition suddenly had problems. I restored the map part to PlayerController to no avail, it is still invisible.

Update, I have no problem with SceneTransition. I was too nervous about the Map problem and accidentally turned off SceneFader without enabling it.

update again, my map disappears as if I accidentally adjusted it to Alpha value. So the above problem is solved,

PlayController.cs Add GameManager.Instance.ToggleMap(); to PlayerController

<code>void Update()
    {
        if (GameManager.Instance.gameIsPaused) return;

        RestoreTimeScale();

        if (pState.cutscene) return;

            //ToggleMap();
            GameManager.Instance.ToggleMap();
            ToggleInventory();
        }
        UpdateJumpVariables();
        RestoreTimeScale();
        UpdateCameraYDampForPlayerFall();

                Move();

I modified the GameManager to look like this, but it gave me the error message

<code>Coroutine couldn't be started because the game object 'MapHandler' is inactive!

can you give me some advice Additionally I call ToggleMap() in PlayerController

After I thought about it carefully, I planned to delete ToggleMap() and integrate it into the same place for judgment. In addition, I found that FadeUI.cs may not be needed here. I will share with you the code that I successfully tested. I also added !gameIsPause has been added to the map button judgment to avoid overlapping with other pause screens and causing multiple screens with different functions to appear at the same time. I don’t know if this is correct. There may be problems that I didn’t expect.

<code>//地圖Map
        if (Input.GetButtonDown("Map") && !openMap && !gameIsPaused)
        {
            openMap = true;

            if (openMap)
            {
                Time.timeScale = 0;
                GameManager.Instance.gameIsPaused = true;
            }
            UIManager.Instance.mapHandler.SetActive(true);
        }
        else if (Input.GetButtonDown("Map") && openMap)
        {
            openMap = false;

            if (!openMap)
            {
                UnpauseGame();
            }
            UIManager.Instance.mapHandler.SetActive(false);
        }

        //背包Inventory
        if (Input.GetButtonDown("Inventory") && !openInventory && !gameIsPaused)
        {
            openInventory = true;

            if(openInventory)
            {
                Time.timeScale = 0;
                GameManager.Instance.gameIsPaused = true;
            }
            UIManager.Instance.inventory.SetActive(true);
        }
        else if (Input.GetButtonDown("Inventory") && openInventory)
        {
            openInventory = false;

            if(!openInventory)
            {
                UnpauseGame();
            }
            UIManager.Instance.inventory.SetActive(false) ;
        }</code>
