Hi! I'm having trouble turning on a display whenever the spacebar gets pressed (the game should pause and display that time has stopped). Here is my code that does that:

public class TimeController : MonoBehaviour
{
    public static TimeController Instance;

    [SerializeField] private GameObject _pauseDisplay;

    private bool _receivingInput = false;
    private TimeState _state = TimeState.Paused;
    private TimeState _previousState = TimeState.Speed1x;

    void Awake()
    {
        Instance = this;
    }

    // Update is called once per frame
    void Update()
    {
        if (_receivingInput)
        {
            InputUpdate();
        }
    }

    void InputUpdate()
    {
        if (Keyboard.current.spaceKey.wasPressedThisFrame)
        {
            Debug.Log("TIME: Spacebar pressed, toggling time scale");
            ToggleTime();
        }
    }

    private void ToggleTime()
    {
        if (_state == TimeState.Paused)
        {
            ResumeTime();
        }
        else
        {
            PauseTime();
        }
    }

    public void PauseTime()
    {
        Debug.Log("TIME: Time is paused!");
        _pauseDisplay.SetActive(true);

        _previousState = _state;
        _state = TimeState.Paused;

        SetTimeScale(0);
    }

    public void ResumeTime()
    {
        _pauseDisplay.SetActive(false);

        _state = _previousState;
        
        SetTimeScale((int) _state);
    }
}

That debug IS getting printed but the display is not activating. It's parent is active and its children are active, but the display itself starts off as inactive.

#

dry tapir That debug IS getting printed but the display is not activating. It's parent is ...

Can you show the console logs?

willow grail Sep 15, 2023, 5:24 PM

#

how can that even compile? I see no ResumeTime method there

dry tapir Sep 15, 2023, 5:25 PM

#

willow grail how can that even compile? I see no ResumeTime method there

trimmed out the parts that aren't a problem

willow grail Sep 15, 2023, 5:25 PM

#

but may be relevant post the whole code to a paste site

dry tapir Sep 15, 2023, 5:26 PM

#

added the awake and update methods

#

TIME: Spacebar pressed, toggling time scale
UnityEngine.Debug:Log (object)
TimeController:InputUpdate () (at Assets/_Scripts/Managers/TimeController.cs:35)
TimeController:Update () (at Assets/_Scripts/Managers/TimeController.cs:27)

TIME: Time is paused!
UnityEngine.Debug:Log (object)
TimeController:PauseTime () (at Assets/_Scripts/Managers/TimeController.cs:78)
TimeController:ToggleTime () (at Assets/_Scripts/Managers/TimeController.cs:72)
TimeController:InputUpdate () (at Assets/_Scripts/Managers/TimeController.cs:36)
TimeController:Update () (at Assets/_Scripts/Managers/TimeController.cs:27)

#

These are the relevant console logs

#

Sorry, just added ResumeTime()

steady matrix Sep 15, 2023, 5:28 PM

#

So.. place a log in resume and see if that prints

dry tapir Sep 15, 2023, 5:28 PM

#

But it's the _pauseDisplay.SetActive(true); that isn't working?

#

The display will go inactive when you press space while paused

#

but won't go active when pressed again

steady matrix Sep 15, 2023, 5:29 PM

#

dry tapir But it's the `_pauseDisplay.SetActive(true);` that isn't working?

I'm assuming it's working

dry tapir Sep 15, 2023, 5:29 PM

#

But it's not becoming active in the scene?

#

And things are connected in the editor

steady matrix Sep 15, 2023, 5:29 PM

#

Becoming active and inactive immediately is a possibility

#

Also having the wrong reference is a possibility

dry tapir Sep 15, 2023, 5:30 PM

#

oh for example if space is presseed for two frames?

steady matrix Sep 15, 2023, 5:30 PM

#

ie prefab instead of scene object

#

None of these things are certain but they are the first few things to observe for

dry tapir Sep 15, 2023, 5:30 PM

#

No, I'm pretty sure it's connected right. I dragged the PauseDisplay scene object onto the TimeController game object script component

steady matrix Sep 15, 2023, 5:31 PM

#

dry tapir oh for example if space is presseed for two frames?

So does the log in resume occur?

dry tapir Sep 15, 2023, 5:31 PM

#

yes, and apparently at the correct time

#

That is, when I press space while paused, I see the log from ResumeTime() but when I press space while time is active, I see the log from PauseTime()

steady matrix Sep 15, 2023, 5:33 PM

#

Alright so the code is working as intended but the objects in the scene aren't doing what we're expecting?

dry tapir Sep 15, 2023, 5:33 PM

#

Yes

steady matrix Sep 15, 2023, 5:33 PM

#

Check the inspector

dry tapir Sep 15, 2023, 5:33 PM

#

At least, the lines of code I want to execute appear to be executing, but the change isn't relfecting in the scene

#

inspector shows the object inactive

steady matrix Sep 15, 2023, 5:33 PM

#

Is the correct object referenced?

dry tapir Sep 15, 2023, 5:34 PM

#

It seems like it. Lol

#

when I double click on the reference, it takes me to the intended object

#

and when i activate that object, i do see what i want

#

Seems like shaningans with SetActive not working how I expect it to?

#

TimeController seems to always be active, too

#

Which is intended

steady matrix Sep 15, 2023, 5:38 PM

#

Or try this: cs Debug.Log($"Display: {_paiseDisplay.name}", _pauseDisplay);

dry tapir Sep 15, 2023, 5:38 PM

#

Ok]

#

Yep

#

Looks right

steady matrix Sep 15, 2023, 5:39 PM

#

Usually when we request to have console logs or inspector/hierarchy information, we'd like screenshots of them.

steady matrix Sep 15, 2023, 5:39 PM

#

dry tapir Looks right

Click on the log

#

What highlights in the screen

dry tapir Sep 15, 2023, 5:39 PM

#

Display: PauseDisplay, _pauseDisplay
UnityEngine.Debug:Log (object)
TimeController:PauseTime () (at Assets/_Scripts/Managers/TimeController.cs:79)
TimeController:ToggleTime () (at Assets/_Scripts/Managers/TimeController.cs:72)
TimeController:InputUpdate () (at Assets/_Scripts/Managers/TimeController.cs:36)
TimeController:Update () (at Assets/_Scripts/Managers/TimeController.cs:27)

steady matrix Sep 15, 2023, 5:40 PM

#

Something should turn yellow

#

Seems like an asset and not a scene object

dry tapir Sep 15, 2023, 5:40 PM

#

Something in the editor should turn yellow when I click on the log?

#

I've never seen that happen before

#

It's an empty game object

#

I mean, it has children

steady matrix Sep 15, 2023, 5:41 PM

#

Something in the screen should turn yellow when you select the log

dry tapir Sep 15, 2023, 5:41 PM

#

I've never seen that happen

#

And don't see it happen now

steady matrix Sep 15, 2023, 5:42 PM

#

Can you show a screenshot of the inspector?

dry tapir Sep 15, 2023, 5:43 PM

#

#

It was working like yesterday and then it stopped and I didn't notice what broke it

#

lol

steady matrix Sep 15, 2023, 5:44 PM

#

Well, nothing seems wrong with the code

dry tapir Sep 15, 2023, 5:44 PM

#

You're tellin me

#

Let me show you the whole TimeController:

https://gdl.space/emihepekam.cs

#

There is a function, Activate which also sets the display to on

#

And that gets called from outside. Can multiple SetActive(true) being called cause a conflict?

steady matrix Sep 15, 2023, 5:50 PM

#

Show the inspector for pause display

dry tapir Sep 15, 2023, 5:50 PM

#

I uploaded 3 pictures

#

It's there

steady matrix Sep 15, 2023, 5:50 PM

#

Ah, alright

dry tapir Sep 15, 2023, 5:51 PM

#

bruh this is infuriating lol

steady matrix Sep 15, 2023, 5:53 PM

#

Do cs Debug.Log($"This: {this}", this);in awake and select the debug message in the console tab.

#

The object in the hierarchy should flash yellow. This should have happened for the pause display object as well.

dry tapir Sep 15, 2023, 5:54 PM

#

whoa i've never seen that happen

#

yes, that happened here

steady matrix Sep 15, 2023, 5:54 PM

#

Meaning there's a possibly that you've referenced something else

#

Select the pause display field

dry tapir Sep 15, 2023, 5:54 PM

#

I don't understand how. Is there a problem bc the PauseDisplay is a child of another canvas?

dry tapir Sep 15, 2023, 5:55 PM

#

steady matrix Select the pause display field

highlights the intended object in yellow

#

:/

steady matrix Sep 15, 2023, 5:55 PM

#

dry tapir highlights the intended object in yellow

Which one's turn yellow?

dry tapir Sep 15, 2023, 5:55 PM

#

PauseDisplay

steady matrix Sep 15, 2023, 5:56 PM

#

Alright, so it's the correct object. And this was the scene object correct?

dry tapir Sep 15, 2023, 5:56 PM

#

when i select the field in the inspector, i mean

#

yes, it is

steady matrix Sep 15, 2023, 5:57 PM

#

And the canvas object (pause display) doesn't activate when attempting to do so?

#

It should turn white in the hierarchy

dry tapir Sep 15, 2023, 5:57 PM

#

Ah, the debug you gave me had the quotes misplaced. One sec

#

For the display

steady matrix Sep 15, 2023, 5:58 PM

#

steady matrix Or try this: ```cs Debug.Log($"Display: {_paiseDisplay.name}", _pauseDisplay);``...

Yeah, doing so from mobile - typo prone

dry tapir Sep 15, 2023, 5:58 PM

#

No worries

#

It highlights correctly now

#

So it does know about the correct object. But for some reason SetActive isn't working! 😠

steady matrix Sep 15, 2023, 5:59 PM

#

steady matrix It should turn white in the hierarchy

So does the object activate when you try to activate it?

dry tapir Sep 15, 2023, 5:59 PM

#

steady matrix It should turn white in the hierarchy

Yep, and it isn't doing that 😭

#

No

#

😠 😠 😠

#

SO WEIRD

steady matrix Sep 15, 2023, 6:01 PM

#

Line 104 _pauseDisplay.SetActive(false);

#

Remove that or comment it out

dry tapir Sep 15, 2023, 6:01 PM

#

fuckin duh

#

jesus
