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

15:05 to see live updates for entities inside the scene view and the game view go to Preferences > Entities > Scene View Mode and set it to "Runtime data" Great tutorial btw :)

@lemetamax 10 ай бұрын

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.

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.

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.

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.

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

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.

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.

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 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 9 ай бұрын

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

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 8 ай бұрын

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.

@AntonVish 9 ай бұрын

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 7 ай бұрын

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.
