❗❗ *Caution:* This video was made using an older version of Unity ECS. While the core concepts remain the same, some of the API and workflows have changed as of ECS version 1.0. I would recommend checking out my ECS 1.0 tutorial video for a good overview of the latest standards for Unity’s DOTS: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-IO6_6Y_YUdE.html Once again, the theory behind the concepts of this video are still relevant, however the API has changed. Stay tuned for further updated videos on this subject. Please let me know if you have any questions either here or in our Discord community: tmg.dev/Discord

ECS has been very hard for me to get into as its fast-updating and information is kind of all over the place, this channel has been such a great encyclopedia of tutorials and has helped me so much. Thank you so much for the hard work you put into these!

@TurboMakesGames Год назад

So glad to hear these videos have been helping you - I do plan on streamlining that information a bit more in the future too

@Tomstachy 2 года назад

Thanks for giving Unity ECS some love! I wanted to rewrite some of my applications which could benefit from advantages provided by ECS but I am little concerned about how little attention it gets from Unity dev team and about long term support for it. I hope that by making videos like that and bringing more people to ECS world you can change attitude how DOTS is treated by its developers by showing that there is demand for this feature.

@TurboMakesGames 2 года назад

Glad to hear you're interested in Unity ECS! While they've been quiet publicly, they've been working hard on DOTS in the background - got a feeling we'll be seeing more of these developments soon!

@MikeGlaxo 2 года назад

Great stuff, please more. :D

@TurboMakesGames 2 года назад

Lots more on the way, glad you're enjoying 😀

@NewbNinjas Год назад

Love this mate. Really insightful. I'm having a min melt trying to absorb all this ECS stuff but one step at a time :)

@TurboMakesGames Год назад

Haha there definitely is a bit of a learning curve, but things will begin to make sense faster the more you familiarize yourself with the concepts. All the best!

@CodemasterJamal 2 года назад

I remember this game. That was an awesome jam. EDIT/ I think I like ECS a little bit more after watching this.

@TurboMakesGames 2 года назад

That's awesome, I had a blast making that game😊 ECS is fun, lots of cool things to experiment with and much more coming soon (hopefully😁)

@HumbertoBytes 2 года назад

@Turbo can you share your IDE setup? how do you get that "Unity ECS" grey text next to your System Base class reference?

@TurboMakesGames 2 года назад

I use JetBrains Rider and it does that automatically for me! Though I do have some interesting custom setups in here that help with ECS development so I might do a video showcasing how I have that all set.

@HumbertoBytes 2 года назад

@@TurboMakesGames I would def love to see a video on that!

@tbunreall 2 года назад

I'm having a bit of a weird problem. I can't get the functions to auto complete in visual studio 2022 unless I type "override void" first. Any idea why?

@TurboMakesGames 2 года назад

Do not know. It's been a long time since I've used VS - especially with DOTS. Hope you get that straightened out though!

@DabManTrips 2 года назад

This is for multiplayer games correct? I want to see if I understand ECS and DOTS correctly. They are supposed to help with netcode and enable developers the ability to create MMO games similar to the way World of Warcraft did with sectioned zones and each zone has it's in own dedicated server allowing higher player counts?

@TurboMakesGames 2 года назад

Multiplayer is a part of DOTS, but there are a number of parts to DOTS. You can think of DOTS as the overall container for things like DOTS multiplayer, ECS, the new physics system, C# Job System, burst compiler, and so on. ECS is the coding structure (Entity Component System) which logically separates data from the logic in the game which allows for much more efficient processing of data by the computer. You can make both single-player and multiplayer games with ECS. Hope that clears things up a bit, I know it can be a bit convoluted 😊

@DabManTrips 2 года назад

@@TurboMakesGames I see. Will you be making videos going over DOTS multiplayer?

@bigfatmomma 2 года назад

Oops. What did I miss. What has changed so that we don't have to rig our own fixed updates anymore to use in DOTS?

@TurboMakesGames 2 года назад

There's now just an update group that runs on a fixed timestep just add your system to the group with [UpdateInGroup(typeof(FixedStepSimulationSystemGroup))]

@AbnerDev 2 года назад

I'm researching and I'm lost, will unity take away the gameObjects and components?

@TurboMakesGames 2 года назад

Nope! At least not in the foreseeable future - if you want an overview of the latest state of DOTS check out this recent video I made where they discuss their roadmap for the DOTS rollout. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-iLpvWp1y23A.html As far as things stand now, ECS will live alongside traditional Unity GameObjects and MonoBehaviour components and those who want to take advantage of the high performance of DOTS/ECS can if they choose to. Hope that helps clear things up for you!

@danishezwan9320 2 года назад

I was actually looking into using ECS, do you think it's a good idea to use ECS to update UI?

@TurboMakesGames 2 года назад

Awesome, ECS is lots of fun! Unfortunately UI isn't natively supported in ECS just yet, as of now you have to do a bit of a workaround called "managed data components" which is basically a bridge between ECS and MonoBehaviours - check out the video I did on using UI in Unity ECS to see how this is done.
