Hi everyone, I hope you find today's topic helpful! I personally (almost) always need to load more than one scene at a time when dealing with Additive scenes, so this kind of system makes life easier! We'll continue this topic by talking about Addressables in a future video, so click the 🔔 (and 👍!)

You are by far one of the best content for unity related stuff. I mean most channels are great for starters , or people learning, you give actual advanced concepts in a very digestible way. Good Job.

Thanks for the kind words - and yes, one of these days when I get organized enough, I'll try to put together a complete library, including all the setup scripts, tooling and so on.

Congratz! Very interesting, clean and well done approach. For your exact system I would use the buildIndex 0 when checking for the Bootstrapper instead of the string, less prone to typo errors. For 3D games you might want to make the Enviroment category the active scene, as Unity will take the environment lighting settings from the active scene.

This is an amazing video! Thank you so much for the effort and quality on the content man, your videos really help me understand advanced concepts that I'm facing right now. I have only one question about the use of await on SceneManager.LoadSceneAsync at 13:13 , I couldn't reproduce that on my unity version so I wanna ask how could you await for AsynchronousOperation like you did there. Thanks for the video again man! :)

@git-amend

Ай бұрын

Glad to hear it! Full support for async operations isn't available until Unity 2023 and above. However, if you take a look in the Unity Utils repository there are several extension methods there that will help you convert an AsyncOperation to a Task or a Coroutine in older versions. github.com/adammyhre/Unity-Utils/tree/master/UnityUtils/Scripts/Extensions We've also made some changes to the repository, in particular to the Bootstrapper class, since this video came out, so make sure to check the repository for this video. Feel free to join the Discord, there is a forum related to this video and these exact questions.

Thank you for sharing. On 15:00 can please explain how the Task.Delay() method was reflecting the changes on the UI even though the progress.Report has not been executed yet?

Your code that references PersistentSingleton... I'm assuming this is from another video? The Save/Load video? Nicely done btw, saved me from having to work this all out on my own and can adjust according to my own needs. Such as using this in collaboration with UI Toolkit instead of just canvas etc.

For anyone who cares, I ended up making a scriptable object to contain all of the scene groups, then used Odin to make an editor window that loads the scene group scriptable object. That way if you're working on a different scene, you don't have to go to the bootstrapper scene if you want to change the scene groups. There's probably a better way to do it, but that worked for me!

It's Adam right? Really appreciate the video. I always recommend your channel to fellow game-dev friends

Would love to see how you handle communication between the different scenes

@git-amend

I would likely use either Dependency Injection or a Service Locator to get references between scenes, and for messaging I would use a Message Bus. These are topics already covered on the channel, so I may not integrate those concepts here for the sake of new viewers.

Minor suggestion. Add Init scene that has absolutly nothing but Load persistent scene additivly. Then once you load actual gameplay scene that hold's light and occlusion data unload this init scene. This way you trigger changing occlussion and light data. Unity has questionable way of changing those 2 data's. 1) Load new scene with those data 2) Set it as active 3) Unload previously set as active scene (at start our init scene) to trigger changing occlussion and light data.

@git-amend

That's a good idea. Another subscriber had an issue with that a few months ago, though more complex.

Would you need a cancellation Token for the Task usage in this case?

Are u sure, that u need in "UnloadScenes -> (sceneName.Equals(activeScene) || sceneName == "Bootstrapper")" to check "sceneName.Equals(activeScene)" , as this will ignore current loaded active scene in initial group and this scene will remain together with all another scenes in target scene group?

Would you recommend putting managers, your Save System, and singletons into the Bootstrapper scene such that they're always available to all scenes at all times and then just use Event Channels to communicate between them?

@git-amend

4 ай бұрын

Yes, in this scenario it’s not necessary to use singletons anymore. The save system already binds on any scene load, and everything else could be supplied with DI or Service Locator, and you could message with a channel or bus.

Thank you, I generally have the problem of Setting Active Scene after loaded with async. For example I load my level asnyc, and after load: I SceneManager.SetActiveScene(sceneName), it "sometimes" gives error even if I do it after completion, when waiting async load. Have you ever had that problem? The reason i want to set active scene is i want to spawn my enemies inside "level" scene in hiearchy, so if it doesnt work, my enemies spawning in Main Scene

This is really cool. Though I'm curious what's the point of using the Ratio = 1 in the report method, since division is expension. It seems like it's taking in a decimal float and returning the same decimal float. If you need to cast it, why not just cast it explicitly?

Thank you for the video! A question if you don't mind. Maybe I didn't catch something important. In the Bootstrapper class "await" throws an error (even when I just Copy & Paste your stuff) The error: Type "UnityEngine.AsyncOperation" is not awaitable. Why does it work in the SceneLoader.cs but not in Bootstrapper.cs?

@git-amend

3 ай бұрын

Being able to await the AsyncOperation type is a feature of Unity 2023.1 and above, so my guess is that you are on an earlier version. There is a discussion on Discord in the #programming-help section for people who don't want to use the latest version of Unity, and a link to the documentation in the description of this video. Hope that helps!

How does this system deals when I want to edit a specific level design scene? Will it get unloaded (due to the bootstrapper) and I'll need to play the game directly to that scene? I'd imagine it would be extremely tiredsome going through all of that just because I added a door or moved a platform by 3 units or something like that

@git-amend

4 ай бұрын

In this case I would make the actual scene group you want to work with / test be a configurable setting for the Bootstrapper - maybe a Scriptable object or Player Settings.

@vazzius

4 ай бұрын

You would have a tool that would load the bare minimum to load the level design in a playable state for testing. Or the level design scene will have a "Cold start" component, that when loaded, if it detects that it doesn't have the needed scenes it will load them. Many ways to do that without relying in the complete game systems to be able to edit.

Hello everyone. Im working currently in an Android URP game for city simulation. It has tons of meshes, and loading the scene makes some devices to crash. Would you say that I can solve that issue by Async loading meshes?

@git-amend

2 ай бұрын

More than likely, yes, asynchronous loading of meshes can mitigate crashes by spreading the loading process over multiple frames, reducing the instantaneous memory and processing load on devices. You would need to look into the logs, if any, to be sure that is the cause of the issue, but it sound probable.

Pass a reference to a SceneGroup into the SceneGroupManager.LoadScenes method to load new scenes together. If you are talking about adding a scene without unloading the current scenes, you'll have to add some functionality for that.

Unity and Rider are flipping out on me because of await: "Type 'UnityEngine.AsyncOperation' is not awaitable" This happens with 'SceneManager.LoadSceneAsync' and 'Resources.UnloadUnusedAssets' - anyone else? I thought maybe it was a Rider issue but I'm getting the error in Unity as well.
