Let's check out Subscenes in Unity, what they are and how we can use them to make Massive Worlds!
Subscenes use Unity DOTS / ECS in order to be insanely performant with nearly instant loading.
When closed they represent their contents as Entities and when you need to modify something you can open the Subscene which will convert all objects into Game Objects that you can edit as usual.
If you have any questions post them in the comments and I'll do my best to answer them.

First of all your typing speed and accuracy sounds like a stampede of little keyboard construction workers and I love it! Secondly, thanks for another great source of information about Unity features that are somewhat buried behind a competence barrier. I refer constantly to the official unity script API page and would never have found this info considering the way I browse it. I've been looking for a mechanism to increase performance on a single-scene game I'm building with a huge number of unique one-off meshes and materials, and I think this will be key to the solution. Thirdly, I continue to find it amazing how your videos make me feel smart and also stupid at the same time! This is great for helping me get an objective sense of my capabilities as a game dev, and I appreciate the opportunity to see how pro-level development is approached. Once again, the Unity community has shown that it follows an unspoken credo of helpfulness, unlike many other programming niches where the professionals and wizards treat the newcomers like worthless scum. CM, you make me feel included and respected.

For example, if you wanted to change the color of the grass would you just change the prefab or would you have to "unpack" all the subscenes, change the prefab, then "repack" them?

@ODCrab 4 жыл бұрын

Cool concept. It seems a lot cleaner than having scenes that are only whole if you remember to load in it's sibling scenes. And I never even thought of doing LOD's for entire scenes. I feel like you should have left a disclaimer when you just cycled through the whole sub-scene array to find the closest ones. That is bound to get slow when you have hundreds of these things. Its a weird problem to solve in code. So I think I would add a collider to each sub-scene and put them on a "sub-scene" physics layer. Then do a sphere cast with a layer mask for the sub-scene layer, from the player's position to find which ones are close. Sort of like a radar.

@CodeMonkeyUnity 4 жыл бұрын

Sure if performance becomes an issue you could build some colliders or just simply test the distance only once per 5 seconds instead of every frame.

Can subscenes be different sizes or must they remain in a grid of all the same size? Say there is a very large scene where the camera zooms out and you want to contain it all in one scene, but there are other surrounding ones that are much smaller. Would this have any long term problems? Assuming all of the subscenes along side the edge of the largest one still have the same length and there arent any gaps within the map.

Just as I needed it, great! One question though; How to handle dynamic objects like enemies? They can't be loaded/unloaded based on the subscene, because they could follow the player for example. And what, if I want to save the state of an object, before it gets unloaded, so when I go back later, the object remains like the player left it? I will surely implement this, but this could be content for some of your next videos =) Keep up those awesome videos! (yea, that were 2 questions ^-^)

@CodeMonkeyUnity 4 жыл бұрын

SubScenes are only meant for either static entities or entities where the state doesn't matter (like a flock of birds) so if you want some sort of state to persist then don't unload it through a SubScene. As soon as you load it loads from the data on the binary file regardless of what changes you made while the SubScene was loaded.

This is a great video and I can't wait to give it a try. One thing I've noticed on this and the Prefab video is you are making Systems instead of Jobs for some of these systems. While I haven't tried this particular one out yet, shouldn't a "SceneJob" work fine to handle all of this or would it not worth with the Burst Compiler? Similarly I've found that spawning a prefab in a Job with DOTS also doesn't work with the Burst Compiler which is frustrating, if I want a Player to fire a Projectile Entity (something that would be incredibly common in a game), not being able to do that in a worker thread seems to be a problem. That, or am I missing something? (I really hope I am).

@iCeDrAgOn2025 4 жыл бұрын

Not every system has to contain a job. Systems such as movement or turning on or off a single entity would run so quickly that it's actually better not to set such up as a job because it would just lead to you as the developer needing to write more code.

@@iCeDrAgOn2025 The new JobComponentSystem in the latest preview is the same amount of code as a ComponentSystem and it'll use Burst Compile by default. You'd think for consistency you'd just use the same one all the time if possible.

Normally I use the ComponentSystem when its something very simple like here just moving a single Player but yes ideally in a proper game you would make Jobs for everything. I believe the plan is to merge ComponentSystem and JobComponentSystem into one so in the future it'll be very easy to convert them. There is a small overhead when creating the job and their goal is to bring that down as much as possible. In terms of spawning prefabs you can do it with Burst but you don't do it with EntityManager.Instantiate(); You do it with a EntityCommandBuffer.Concurrent

@andrewshandle 4 жыл бұрын

@@CodeMonkeyUnity I definitely understand that for input, since Job or otherwise, it'll pretty tiny, it's not like movement, rotation or pathfinding which might influence 10s of thousands of entities (depending on your game of course).

ECS -> SceneSystem.LoadSceneAsync has a very huge peak (FPS drop) at the really begin and it takes 37 frames to load the Subscene Mono -> SceneManager.LoadSceneAsync does not have any huge peak at the start and it takes 21 frames to load the scene (LoadSceneMode.Additive) During scene async loading they both have a similar fps It would be interesting if you create similar tests, to compare these two worlds (Mono and ECS). I guess with your experience you can create more reliable test results than mine.

As a theoretical, can you still have interactions in unloaded subscenes? Say you have a NPC chopping a tree down in an unloaded scene, can it make a sound? ;P But seriously, if there is a dynamic system in an unloaded subscence, can you still have its effects spill into loaded scenes? (Ex. A dam is set to blow on a timer and flood a region, but no one is around to see it, can other regions down river get flooded anyway?)

@washynator 4 жыл бұрын

I'm an idiot, so you should probably wait for a comment from someone who knows anything. But I would imagine that it wouldn't be possible to have stuff happen in unloaded scenes (they are unloaded, after all). My (stupid) solution would be to use some kind of a trigger to make the thing happen anyway (you can use whatever system to load the scene to make the flood happen). For example game time? As in "after the game has been going for 50minutes, load the scene with the dam and destroy the town, then unload the scene until the player comes near".

@@washynator That's certainly one way for that sort of thing; but I'm thinking about dealing with massive dynamic environments where things can happen even without player involvement.

Really just thoughts that came to me while watching the video.

Unloaded Subscenes don't really exist, if you look in the Entity Debugger the entities don't exist.

You didnt mention much about the LOD system with subscenes, but are these essentially just a substitute subscene if a subscene is very far away? Sounds like it could be faster than just relying on LOD gameobjects in a single subscene , but not a huge difference unless you have thousands of objects in your subscene

how did you use the subscene I entered Unity and if I drag a Scene inside my actual Scene it is not child of the first

@Andrew90046zero 4 жыл бұрын

So this subscene stuff can be used without dots right? Or at least, without me needing to use ECS in any way. Like I can still safely use this with Monobehaviours EDIT: Nevermind I just watched the rest of the video lol But just to make sure, because I plan on having massive levels in my game, and I have already made a system for loading and unloading parts of my game, but I haven't yet made it so it saves to file or anything. But with this system, does it support destructible levels? Like you can modify parts of a subscene at runtime and it still unload properly?

@CodeMonkeyUnity 4 жыл бұрын

Everything inside a Subscene gets automatically converted into Entities. But you can mix Entities with Game Objects. So even if your game is fully made with Game Objects you can still use Subscenes for dynamically loading any static objects that don't interact with your game objects. I have not experimented with modifying them in runtime so not sure about that.

Maybe a stupid question, but say an enemey is supposed to patrol 3 different subscenes, how can we ensure the patrol actually happens when we unload one or multiple of the subscenes?

3:49 when I right-click in Unity v2020.1.6f1, I don't have the option to "create subscene" at the bottom of the dropdown menu. I just have 'properties' as the last menu item. Is there some setting I need to check or some package I need to install first? Do I need to buy Unity Pro version? Is there another component I need to add somewhere? What's the missing information here?

Do you have the Entities package installed? Haven't touched DOTS in quite a while so it's possible the menu changed.

Aren't infinite worlds still plagued by floating point precision issues? Or do subscenes fix this by default?

@alcofribasnasier1838 3 жыл бұрын

floating points can easily be fixed with a simple return to origin, and it doesn't take more than 50 lines of code to do it.

I've thought of using this for large open world games. Like GTA. Though I wonder, what stops you from making an entire game like this instead of using actual scenes, like making Half Life entirely into subscenes to remove the loading in between? Imagine making the entire summer camp in Psychonauts into one single map using this method. Thing go on in the background far away but the objects's functions are inactive and are basically in a passive mode that simply makes them move. Or having a massive building surrounded by a smaller base with a circle of water to a whole city. And you can see everything moving and being alive and go there. As I said, passively active to give the illusion of everything being one scene.

There's nothing stopping you, that's exactly how massive games like Skyrim are made. The world gets loaded in and out as the player moves around. It can become very complex though which is why a lot of games use the typical level structure.

@magnusm4 4 жыл бұрын

@@CodeMonkeyUnity That and open worlds means typical optimization methods don't work like disabling objects obstructed by view. Even if they're far away, it's still a whole open plane of objects you'l have to low poly render and the sheer number alone can cause trouble even with less than 300 polygons. Then the engine itself can be limited. Like with Cursed Halo he explains there's a vertice limit of about 20 000 or more. This means regardless of your optimization you're automatically constricted by the engine unless you do like some developers and either modify the engine, or make a third party software to allow more to be rendered without lag or crashing.
