    Any news on when ECS will be fully integrated?
    Also
    Brackeys, we will need a hard core tutorials on pure ECS once that is integrated. I looked online for tutorials on it and on data oriented design and it's pretty unbelievable that there are no tutorials to speak of.
    The only thing I found are two talks given by two dudes on how awesome this way of coding is. And that's it...
    So all that fuss about design patterns, singletons, data structures, all of that is useless now (in pure ECS)? Pretty much use only value types, structs and arrays. No more classes no nothing. In a way, it makes things easier.

    • @aronlinde1723
      @aronlinde1723 6 лет назад +11

      Design Patterns are still very much a thing. Heck, even in this video Brackeys used a non-static flyweight pattern. Pure ECS is no exception, just that the list of things a dev will have to mentally juggle gets shorter and the pipelines get more specialized. It's nice when the framework hides all the grunt work like this, but you still need to have the basics to understand what is happening behind the scenes. Someone mentioned that this functions like MVC, which isnt a bad comparison. You can see the separation of concerns and how it resembles SOA design elements. While my current game won't get this I think I will try on my next prototype to work in this and see how it goes. On paper it's the right direction as monobehavior is a goofy blending of component and OO design that makes service building pretty awkward.

    • @sheridan0451
      @sheridan0451 6 лет назад +2

      Yeah. I wrote my own ECS engine in Go, and the design patterns you use are still very much still valuable. This isn't as big of a shift as you might think. It's a new way of approaching how data is treated and it separates responsibilities better. So, you might even think about it like reorganization rather than paradigm shifts.

      It's how Unity should have been from the start, it sucks that the change is so radical it kinda makes you wanna learn a different engine. I think this will be for the best, I personally used a somewhat hybrid entity-based approach on my projects, but I still have Monobehaviours that I don't need on some objects which was very inefficient, and that's the thing, monobehaviours should have been optional since the beginning of Unity, oh well.

    I see people complaining because its hard to understand. I get that. But we had to figure out how to think in object oriented (which isn't going away soon) so ECS is no different. Just a different way to break down logic. I'm no expert but I love optimization so I'm really want to try it out!!!!

  • @Xonatron
    @Xonatron 4 года назад +4

    7:54 - Time.deltaTime is already a (public static float) variable, so it is already optimized down into a variable and you are not skipping any code by creating your own. Its value should remain the same for the entire frame found within OnUpdate(), so even data preservation does not apply here. The methods that update Time.deltaTime are performed external to accessing it and have already occurred for the frame in question. So, we are good to go with just accessing it directly.
    (Correct me if I am wrong! Am I missing a caching issue?)

    • @creative0ne
      @creative0ne 4 года назад +1

      To be sure we'll have to look at realization of deltaTime. It could be a variable which is updated once per frame or it could have a getter which pulls the value every time you access it. If it's the first case then you are obviously correct.
      By the way, for example in Lua it would be extra overhead because you'd have to index Time table and it would be better to localize it outside the loop scope.

    So from what i understand, its basically just making it more like a functional programming paradigm? you just distinquish the data on each entity and run the same function on it based on the data?

    • @r1pfake521
      @r1pfake521 6 лет назад +16

      The point of the ECS is to combine it with the new Job system to make it multi threaded, this is where the real performance boost is coming from + the better memory layout (not by storing the delta time in a local variable, like they said in the video, that makes no real difference)

    • @dmitrij34

    • @kdorland
      @kdorland 6 лет назад +13

      I wouldn't call this approach functional style, which usually means immutable data structures, recursion, pattern matching, and stuff like that. This is more like replacing the object oriented paradigm with a more data driven paradigm.

    • @petter9078
      @petter9078 6 лет назад

      No this is not exactly functional programming, but pretty similar!

    • @petter9078
      @petter9078 6 лет назад

      When you use unity job system, you could maybe call this similar to functional programming since the structs are immutable. And you do not modify a struct, you create a new one.

      The ECS (+ Job system) is not meant to replace the current system, they are meant for "heavy tasks" like runtime random level generation or games where you have thousands of units etc for a let's say first person shooter where you only have a few enemies it won't make much difference and it's not meant to be used for these kind of things

    @lorenzo501 4 года назад +3

    3:56 elaborate on this please.. you didn't mention how exactly that isn't performant nor how that isn't easy to read/understand XD because to me it makes total sense how it works and is easily read and understood as well.. so I have no clue why you are saying that it isn't when I have no problem with it whatsoever? I make variables (private/protected fields and public properties seperately) and put them in fancy regions when there are multiple of either one (fields/properties) and you can easily make use of it, its always found on the top of the script when you need them and I see no problem at all with them. The only thing about performant that I'm aware of is that I can instead of creating multiple instances of classes, just create one instance that is shared by using structs that contain the data so I don't need a seperate instance to hold all the data for each usage. So basically this ECS system prevents the need to do that by introducing a new layer so to speak, makes this more convenient without the need to create structs and preventing to create multiple instances. I guess that's it then, still trying to learn more about this ECS/DOTS thing, but quite a lot of effort to be able to make use of it at all. I suppose those extra steps like with the package will not be necessary in the future as it will get included by default or is this stuff actually not necessary to be used in all cases, therefore providing it as an package (with such confusing steps to get it.. eh idk what to think about it at this point, but I'll continue watching your video now lol).

      When the job system and the compiler are fully integrated, why would you want to keep using the old system when you could be safely multi-threading and get way better performance and lower power consumption? Oh it will make a difference. Sure the old system will still be around with mono behavior and all, but it will be outdated. Best to keep with the times imo.

      now think about it when u have 3 boxes and each one is labeled, and you also define exactly what inside each box ( e.g. Rotator and Transform ) so you don't include any redundant files, which obviously would be faster and better

    "While data-driven design does prevent coupling of data and functionality, in some cases, data-driven programming has been argued to lead to bad object-oriented design, especially when dealing with more abstract data. This is because a purely data-driven object or entity is defined by the way it is represented. Any attempt to change the structure of the object would immediately break the functions that rely on it." - thnx i'll pass :P

    • @bobmarl6722
      @bobmarl6722 6 лет назад

      Using data driven code is more rigid and complex, but you have to understand that object oriented code is not natural to the computer. Objects are abstraction to make it easier, but the more abstraction you have between the computer and the programmer, the shittier your game will run. I've been working on a strategy game using data driven design way before Unity even talked about it , this allows me to run 200 000 soldiers at 60 fps on an average machine. If you're just making little phone games as a hobby, then of course, you can ignore data driven entirely. Any serious game out there have been using this type of architecture for a while, it's just Unity has been slow to it because most of its user base are beginners.

    • @iplaymages9847
      @iplaymages9847 6 лет назад +1

      "If you're just making little phone games as a hobby" - let me disagree with you. more true would be to say if you're doing ANYTHING (god of war, devil may cry, resident evil type of games) you're better of with OOC and only good use of DDC is when you want to have 200 000 soldiers at 60 fps BUT even then, it's 2018 and PC power is growing so that kinda becomes less revelant. so that said maybe especially "If you're just making little phone games as a hobby" - DDC is better opinion because of resource limit. in general it's still not worth using because of the downsides - upsides are what?! better performance in very specific games that's rarely created?! i can't even think of any game where u'd have or need 200 000 soldiers (mby total war, idk).

    • @bobmarl6722
      @bobmarl6722 6 лет назад

      The 200 000 soldiers is an example, but that's not the point of it. The point of data driven is to allow your code to be multithreaded properly hence taking advantage of all cores. If there's one platform that needs to take advantage of all cores, it's console games because the hardware is so limited. If anything needs data driven, it's ESPECIALLY games like god of war. God of war wouldn't be possible without data driven. There's a video about how Destiny 2 uses multithreading and data driven in its engine if you're interested, but every AAA console game has been using data driven for years.

I understand the idea and how it can improve performance, but it's just so bloody syntax heavy for such simple things. It also requires yet another window just to keep track of these entities. It's too much all at once and it feels unfinished, just like the shader graph in 2018.1.

      Well they are both considered experimental features for a reason. Hell look what you have to do to even access ECS. It's not meant to be used by everyone, it's made for testing and learning. And there's no way that Unity would ever remove object oriented programming, because there are tons of people too stubborn or lazy to try to make the switch.

    • @SubjektDelta
      @SubjektDelta 6 лет назад +65

      This isn't needed when you program an FPS or something. This is used for mass calculation like civilization 5 where everyone has its own AI or what not.

    • @dmitrij34
      @dmitrij34 6 лет назад +13

      Dacommenta you don't get it.
      First of all, it is optional, for people like me, who want crazy performance for 100,000 of objects by carefully using CPU cache, and utilising many CPU cores. So if you don't want to use it - don't use it.
      Secondly - yes, good things take effort to learn. It is easy to write shitty code that works. But when you suddenly want more performace, but you can't get it because of the way you have written it, or when you have a bug, but can't figure it out in an unmaintainable mess that you have created, you just want to burn down your software and start from scratch. It is an illusion that coding is easy. It is a work, and an art at the same time. I personally admire people who are able to write clean and performant code.
      In regards to your complaint - I don't get it, how can you be mad about optional feature?

      @@RatKing59 "Most inefficient" is quite relative. Of course it's not going to beat in term of linear data and reduce of cache miss. But who is making games with 100,000 entities? And if It takes me 6 times more times to code the same thing, to save 1 ms/frame of CPU time, is it really worth it? Also, Unity offers IL2CPP, which turns managed intermediate language into something very close to pure C++. The difference between IL2CPP vs pure native is so small, more game devs wouldn't even notice it.

    • @MrCorrectify
      @MrCorrectify 5 лет назад

      It can be much easier to code, though not as easy to wrap your head around, and there are some things that are certainly more difficult. Keep in mind when you create a system, you're done. Drop a component on any entity and it comes alive. You can rapidly created gameplay just by mixing and matching components. As you build a bigger and bigger library of systems and components, you can whip up millions of types of gameplay in minutes.
      Unity components work similarly, but because the systems are built in, you require constant management of cross script and scene communication, so in that sense it's both easier and more modular (on top of the fact that its WAY faster to have one group of logic for hundreds of components, verses hundreds of components each with their own logic running).

    • @LightStrikerQc
      @LightStrikerQc 5 лет назад +1

      @@MrCorrectify You haven't answered anything of what I just said. Repeating "it's easier", doesn't make it easier. You can do EXACTLY the same thing with Unity components, but with ECS you cut yourself off polymorphism and a lot of other useful OO tools. Cross-script communication is an issue you will encounter as soon as you don't do a small game, and with ECS you're stuck, unable to properly offer that communication.
      ECS has advantages, but ease of writing and simplification ISN'T one of those.

    I'm really excited about this new system! It seemed that previously if you wanted to do anything performantly you basically had to do it in pure C# and avoid using Unity systems as much as possible, which kind of defeats the purpose of providing a game engine to use. This new stuff is the right direction without a doubt. If you read the docs linked, they're including injection and carefully minimizing memory allocation and access, this stuff looks really cleverly designed.
    Also, if this looks scary remember that this is pretty low level, there will be higher level helpers built on top of it to simplify things, and even though that no doubt adds overhead, it will still be way faster than this mono-behavior stuff.
