I just recently added a pause option to my game for the first time and I also did it by setting Time.timeScale = 0 and then having a static bool that kept track of if the game was paused or not. I find doing it this way is pretty easy and intuitive. Also did not know that you can just pause all AudioSources just from one line of code lol, thanks for bringing this up!

The same thing could not function properly on the WebGL; both Ignore Time Scale and Remember Read Positions were enabled and the music suddenly went rapidly off while the audio is paused.

This was really helpful. I've traditionally just been using a GameState object that sends out a 'GamePaused' event, and having all of the objects that need to respond to that and set their own 'isPaused' state accordingly, but things with Physics of course don't follow that so that's been a challenge. I totally didn't know you could do this, this helps so much, thank you! Love your blog too!

Hey, dude, you won't believe the immense help you provided me with! I can't stress enough how grateful I am. Remember when you mentioned that crucial detail at 2:08? Well, I was in the middle of creating the Pause Menu for my game and encountered a perplexing issue. Whenever I transitioned back to the Game Scene from Main Menu, the game froze completely. I tried everything, even deep profiling, but couldn't make any sense of it. All I could observe was that the 'asyncoperationtocomplete()' function was taking an unusually long time. However, thanks to your advice, I decided to set the timescale to 1 before exiting the Game scene, and voila! It miraculously worked! I cannot thank you enough for your invaluable assistance!💕💕

I recently had issues in my game with using TimeScale at 0 to pause, as it can potentially stop other scripts in the game midway through execution. The way I got around this was to have the pause button set a bool, then run the check to set the Timescale to 0 in LateUpdate() as this is more likely to run once everything else is finished in that frame.

to be fair, this would generally apply to most things, as the majority of engines or IMEs that have deltaTime defined will generally also define timescale and unscaledDeltaTime, its pretty standard

I'm using the new Input System which fires an event when P is pressed. This flips a boolean flag property: it's true, run the Pause logic. If its now become false, run the Unpause logic. Note that this is a C# getter/setter property, not just a boolean variable on its own. The pause logic sets Time.timeScale to 0 which effectively freezes the main game state, but also uses unscaled time to allow certain other things to carry on (e.g. animations on the pause screen itself). It also uses the Input System to disable/enable certain Actions, to in effect "lock out" certain controls while the game is paused, i.e. the gameplay controls are locked out while the Pause and Quit buttons still work. This prevents the game from going utterly haywire once unpaused again. I'm convinced my method is absolute crap and fully expect to stumble across a much better and cleaner way at some point.

@holybiscuits7714 13 күн бұрын

2:21 very nitpicky catch here, but deltaTime is actually the time between the last frame and the frame before it, not the time between the last and current frame. This is because when deltaTime is called, the program doesn't know when the current frame is going to appear, so deltaTime is a close approximation of how long the current frame will *probably* take to render. Jonas Tyroller did a great video about this, in case you haven't watched it. Given that this video was released over a year ago, I trust that you've learned a lot more and will have fewer similar errors in your course. I preordered it and am very much looking forward to its release!

@happypixls Жыл бұрын

First of all, awesome video, thanks a ton for sharing this! Personally I don't modify the timescale at all, but rather keep a collection of tracked objects that are subscribed to the pause event which pause/unpause their behavior.

I was hoping to find a video on scene management. I have scene1 which on a button click uses a function to load scene2. In the OnSceneLoaded, I check if the scenename is Scene2 and if it is , I tried Gameobject.Find to find a text field in my scene to put something into it. But that line of code is dying, getting a NullReferenceException : Object reference not set to an instance of an object" error. How do I make sure the scene is completely loaded, i.e. all gameobjects on it have been instantiated before I try and Find them? Your help would be most appreciated.😀

Thanks! Do you mean @08:18? It checks if the game is already paused and then changes it to the opposite state, which is why it probably looks the wrong way round.

Excellent video! I tried using timeScale=0 and it works great in editor, but in a build Windows says the app is unresponsive after being paused for 15-30 seconds, basically crashing the game. I read something about setting it to 0.001f instead, but that didn’t change it. Do you have any idea on where to look for any code that could cause this to happen? Thanks!

@GameDevBeginner Жыл бұрын

I hadn't heard of that but I'm going to look into it. It's possible that something else is happening, so maybe try pausing a build of a blank project to double-check.

Great video, how can I do when you unplug the console while playing it automatically stops?

@GameDevBeginner Жыл бұрын

Do you mean when the controller's unplugged? The Rewired plugin, as an example, has a disconnect event, that you could subscribe a pause function to. There may well be a native version of that, I would've thought the new Input System has something along those lines too.

@gekkek2005 Жыл бұрын

As obvious as it reads(hehe) you can also pause by disabling movement scrips storing vector values, (dont forget about gravity). Also the way shown in the video is better by any margin of imagination.

@crazyone3494 8 ай бұрын

Been looking into some threads and videos, none managed to answer my question... You see, i got 3 methods, PauseMenu, Inventory Menu and GameOverScreen, all of then use the same structure as this: public void PauseMenu() { if(Input.GetButtonDown("Pause") && isMenu == false && isGameOver == false) { isPaused = !isPaused; PauseScreen.SetActive(isPaused); } if(isPaused) { Time.timeScale = 0f; Debug.Log(Time.timeScale); } else { Time.timeScale = 1f; } } The thing is, only the last modified works, they don´t work at the same time. I have seen that´s because since they do the same thing and Update isn´t affected, it just chooses one and ignore the others, is there a way to circle around this?

Thanks for the tutorial. I've been having a problem with the pause function in my game: i am doing a game about protecting a cell in the middle of the screen by clicking on targets and dragging others for points, i applied the pause script and it works in stopping time but doesn't prevent interactions with the enemies and the point tokens, they can be dragged and removed, all the tutorial talk about pause time but it doesnt' work when my game doesn't use it or the only thing using time are the enemies slowly going toward the center. Tried 2d and 3d sprites, expecting it was a thing related to it but didn't. Any help you or anyoen can provide, please?

@GameDevBeginner Жыл бұрын

So my thinking would be that the type of interaction you're talking about is, essentially, input, which because it's not scaled by time in any way, you would need to turn it off yourself. Maybe using a global event in whatever script you're using to trigger and detect those clicks.

I still have some problems even if I believe this video gave me a lot of useful information. I use timeScale = 0 to pause my game when my level loads because It's supposed to wait for the 3 seconds countdown to end and then timeScale goes back to 1. The problem is that my countdown timer is stopped because of the timeScale = 0 xD I can't figure out how to only make the timer not afected by timeScale =0.

Don't use time controlled pause! When you need something to need running and another thing to be paused all this work goes to trash. Instead use the last option that the video give. A global variable that objects can read to know if its paused or not.
