Oh dear! There goes my last brain cell! Rest in peace.

[@KahlisManualtech-ul1rl]

This is the most concise and direct to the point tutorial I found about ECS. Thank you

[@erminmahmutovic927]

Great work, after watching many different video tutorials, this was one of the best explanations ever. I hope it will be more tutorials about ECS in the future.

[@GrayFoxware]

Thank you so much!!!! looking forward to another ECS video!

[@mindurownbussines]

Thanks man You're really good at teaching Wish you the best of luck

[@stormer268]

Thanks a lot! This is the easiest to understand ECS tutorial I have ever seen!

[@lemetamax]

Holy SHIIT Thanks!!!!! Liked and Subscribed! Please make more of this. This is well explained. You ROCK!! BTW: Go to Edit>Preferences>Entities and change Scene View Mode to Runtime Data. Then your entity's positions will also be updated in the scene view and not just the game view.

[@WornTraveler]

I just discovered your channel, after a quick watch and checking some of your other content I'm super stoked to check it out! I recently had a bad stress test- character controllers just GOBBLING up my fps- so I am hoping the extra effort in setup can give me better performance and still keep 1,000 dinosaurs on screen 😂

[@alfonzo6320]

simple and straightforward tutorial. i like it!

[@Baron.Marcus]

Super well done tutorial - very clear and well paced. Thank you! DOTS is of course a powerful development, and your uniquely clear explanation and demonstration opens the door to developers adopting this new technology. Also, as in my case, it clarifies why I would NOT use DOTS for now, until it is further abstracted in its implementation (more straight forward to use - as I'm sure it eventually will be). This is a good thing that will manage the expectations of developers as the technology develops - and that decision made possible by the clarity of your great tutorial.

[@enesdinc6173]

It was a clear explanation for ecs thanks. 🙏🙏

[@MrZtapp]

Very useful tut, good job and thank you.

[@imatendra]

So much Fun Loving Explaination 😅

[@Badders1977]

Thank you, that allowed me to visualize why DOTS exists. Great video!

[@KocTechniczny]

omg the best ecs tutorial!!! please do basics of physics 🙏

[@90Bilu]

Thanks you very much !!! We need more like this please ! some idea to explore with ECS for you next video : Control a player, spawn enemies, shoot or punch them, collect coins, hold object. A series to make a mini-game perhaps ?

[@_Braska]

Amazing tutorial! Most of ECS videos contains too much yabbering. This was much more on point.

[@paulpach]

Thank you for this tutorial, this explains a lot, and it is up to date. That said, that is an insane amount of boilerplate, unity failed miserably at making this usable.

[@MegaVranjanac]

This guys deserves a sub, who dislikes this video should not get in game dev at all. This tutorial is easy to understand and so well explained!

[@dev_reimu]

I was excited about DOTS, thinking I would escape the boilerplate-hell that is OOP. But this just feels like an overcomplicated hybrid- It's even _more_ prior work if I wish to do anything.

[@user-jd3so8tj2x]

wow I love your video!thanks!

[@kdawg717]

Thank you for explaining that this is impractical to use.

[@ForlornU]

Great video!

[@nite_owl_was_here]

I can sort of see now why Unity were careful about recommending ecs for most unity games. The fact that it doesnt completely replace the monobehavior/gameobject systems makes it really complex. Using something like Flecs in c++ or Bevy_ECS in rust is way less complicated imo. Great video though, helped me understand it.

[@TaliyahP]

It really seems to be a suplementary tool for resource intensive use cases rather than a full on replacement of the MonoBehaviour API

[@muuubiee]

It's not recommended because not everything is implemented yet.

[@nite_owl_was_here]

@@muuubiee which i find ridiculous. idk but with all that money, i bet they could focus it if they wanted to. this feels like a classic "unity thing"

[@tony355367]

Very clear video, thank you for sharing. I hope unity can replace the old program code. ECS is too powerful, but now it is too complicated.

[@usercontent2112]

Wooooooooow, Let's goooooooooo

[@DRSNAKE008]

in the ijbentity execute function parameters with ref are read write and parameters with in are read only

[@AKGameStudio21]

It'd be so good to see you do a vampire survivors like DOTS tutorial, or retro games like asteroids on steroids to better demonstrate the power of dots. I'd really like to get into it, but resources are still either outdated or scarce sadly. Great video tho, nicely done

[@rytisss92]

Hey, really great tutorial thank you! I have a question. Currently in my unity project I have a city with a lot of traffic that uses coroutines to travel from node to node. If I convert my traffic from GameObjects to EntityObjects like in your example, is it possible to still use coroutines in this ECS system or will I have to make changes to use the update function instead? Thanks!

[@developershub_org]

Coroutines attach to GameObject and to the extent of my knowledge there is no similar method to use out of the box in DOTS. It shouldn't be hard though to make the changes and move your entities using job system.

[@user-yk6wg6pl1i]

thanks

[@DRSNAKE008]

good video make more

[@mrbinggrae5954]

Please make more DOTS series. 😭

[@omeryilmaz1021]

is it necessary to create a subscene for ecs to work

[@Knuckles2761]

Hint: at 15:48 some older versions of Visual Studio may highlight ISystem with red (as mistake) and advice to implement interfaces OnCreate and OnDestroy. Don't do that, just ignore that advice. Everything will be fine in Unity. Or update your VS.

[@devrocks80]

Just need to Ensure visual studio unity games development tools is added to the visual studio installation and that visual studio is set as the external ide in editor settings

[@Spaaace]

10/10 would cubeJub again

[@StickyLabDev]

is it worth it

[@restushlogic5794]

Note: when you learning DOTS, please empty your glass of OOP.

[@SoaringSimulator]

In the next video explain when to use it. For example for static building? for one airplain movement? for grass shaked by wind? or clouds formation? no All of this is not good for. If you can explain where to use it looking games and pointing to the objects. And when shaders or static meshes need or do not need DOTS. Thx!!!

[@thev01d12]

Don't. This is a clusterfuck incomplete system. I doubt any proprietary engine such bad architecture in the name of ecs. Switching to unreal would be easier.

[@SoaringSimulator]

@@thev01d12 DONE!

[@v0ltdev]

​@@thev01d12 unreal comes no where near the performance ECS gives, yeah is complicated but its not like you have to use it in everything, this is ment for simulations and having 1000s of objects on screen and is only getting better, thats the trade off, you get performance that rivals assembly on top of more complexity

[@TaliyahP]

You can technically use it for simple logic, but it would honestly be overkill and would bloat your codebase. ECS is primarily for when you need A LOT of expensive logic. Like say you have 1000 objects doing complex movement code. Make them Entities

[@SoaringSimulator]

@@TaliyahP Hoo like for Cl and Cd for each single section of a wing! Thx!!

[@mrcallum1995]

Why were your classes and structs partial?

[@developershub_org]

docs.unity3d.com/Packages/com.unity.entities@0.50/manual/upgrade-guide.html#partial

[@JaraFagla]

Sir, why removed Battle Royale Series tutorial video?

[@developershub_org]

It was getting too complex. I am creating a new series on TPS multiplayer and the first video will be released in a couple of days.

[@JaraFagla]

@@developershub_org Thanks for giving the information, sir. We have learned a lot from your video, hopefully we will learn a lot more in future also. Thank you sir.

[@AntonVish]

It’s clear now it takes 15 minutes to prepare rotation… but why? what the benefits are? do you have some real life examples where you can apply it?

[@ADreamPainter]

The biggest advantage is that it structures data in such a way that the game can run at least 10X faster. The default way unity works, requires a lot of movement between the cpu and memory. The cpu has a cache, where that small chunks of data are stored close to the cpu for easy access. Default unity, will flush the cache, retrieve data from memory, flush the cache again, many times each frame. It also uses a single thread for most cases. This method allows a large batch of data to be loaded into the cache and processed in a large chunk. This opens up the ability to utilize multiple cpu cores simultaneously. This means much higher framerates and/or higher quality graphics. There are some games in development that have entire armies fighting each other. This system makes something like this possible. Also for mobile games, it can also be an optimization for using less battery power. So very useful, and versatile.

[@AntonVish]

@@ADreamPainter well, thank you for the details. so why then every tutorial is about rotation :) okay, joking. noone will solve my problems for me…

[@ffaimbotgamer]

Sir can you please 🙏 make full series of battle royale series please 🙏🙏

[@developershub_org]

I might create a battle royale game with netcode for entities, but it might take a while before I start posting videos about it.

[@ctex10]

​@@developershub_org long mobile mmorpg series could also be nice :)

[@theogramme_official]

so much boilerplate and dust to do one simple thing... it makes no sense to use ECS with this workflow

[@WalterRDK]

Great tutorial, but this is too complex... I can't imagine the complexity of translating a full game to this.

[@ahmed.2002]

I want you to add in-game gem purchases in Clash of Clans
