Should i use Hybrid ECS for a production game

I am currently creating a playable that will become a full game set to be released in 2020.

My team and I are considering shifting to Hybrid ECS. However, on the Github page, it states that it should not be used for Production.

Can any studio or developers here on the forums tell us if it is a good idea to use it or if we should keep away from it?

 

We use it in production

 

Thank you for your reply.

Would you say that it has improved your work flow and / or your game?

 

Performance bust, huge amount of objects with veeery low cost. Code more reusable than in OOP.

 

For hybrid ? since I don't think hybrid will give you a performance boost. Hybrid is about using ECS because you want it. You need pure for performance + burst + jobs + build.

 

In my case most part is pure, some things in hybryd. Also, hybryd gives you perfomance bust, not big as pure of course, if compare with legacy approach.

 

It would be misleading to claim hybrid gives a measurable performance boost like what the OP is asking. Hybrid will allow some optimisations but nothing like the scale suggested

 

optimisations not give performance gains based on what you say? I worked out both the legacy approach and the hybrid and pure, and the performance gains yield that hybrid approach that is naturally pure, the difference is only in the measurements, if the hybrid approach is small, 5-10% (on average) then with a clean approach these figures are higher order

 

Oh my bad sry, I'm not clearly read what you say, He mean hybrid, and not pure Yeah busts in my first post is pure, not hybrid

 

Off topic, but I gotta say you have a really good looking game!

 

@eizenhorn Can you elaborate on how you create AI with ECS i really cant wrap my head around it maybe its because im new to the concept

 

NavMesh api have small jobified API -NavMeshQuery can be called inside jobs. Watch some threads in this forum branch, some peoples shown jobified nav mesh solutions.

 

Very cool effective presentation.

What I would like to second, is to use mix of Hybrid and Pure. That where gain is won. If pure ECS is not the option for any reason, Jobyfing will be way to go then.

 

@eizenhorn

Can you by any chance link to some articles that helped you?

 

This forum

Official samples and docs, even can be quite vauge

Thank you for your feedback Yes, all the mechanics in our game have moved from the old approach, to a new, fast ECS that gives us simply unimaginable scope for development, of course there are moments that have not yet been transferred to ECS, for example the interface (to be honest, the interface while just in the prototype, now it is actively working on it). The mechanics of citizens (birth, death from starvation, leaving the city if there is not enough housing, the transition from ordinary conditions to workers, peddlers, builders, gravediggers, etc., hunger, disease) is pure ECS, the mechanics of resources, their movement, appearance , destruction, all trees and rocks on the map are also drawn and culled on pure ECS (each tree on the map is static Entity with its own set of parameters for loggers, cliffs is just dummy Entity with instance renderer). Buildings not transfered to ECS yet, because now they not combined in single optimized mesh, and from day to day artist change some elements in the search for the ideal appearance. But for parts of the system that have not yet switched to ECS, the Job System are already being actively used, for example, to generate fog of war and construction grid. Yes, in the near future, I planned to write a detailed article about our experience in switching to ECS, its use, pluses and minuses. One question, you mean a new thread on the forum or the preparation of a quality article for the blog, I apologize for clarification, just to understand clearly

 

First of all watch great example from Nordeus:

And github with source code:
https://github.com/Unity-Technologies/UniteAustinTechnicalPresentation
But dont forget about latest changes:
https://github.com/Unity-Technologies/EntityComponentSystemSamples/blob/master/ReleaseNotes.md

 

Great insight. thx.

I suppose with latest updates, demo will be well broken

 

That's why I attached a link to the release notes But to understand the basic approaches for implementing collisions, navigation is not a hindrance It is not necessary to run a project to understand the code

 

True.
However I did watch they technical video while ago, and they did explained very well, how they doing collision.
Is very interesting approach. And proved works well with 2D movement. They have nice discussion and explanation, how they deal with minions and collisions, as remember. And some tricks on spatial mapping, or something like that, when more than one minion was in grid cell, while arrows fall, getting damage etc.

Great learning source, true.

 

That Presentation repo IS SO USEFUL i think unity should link to this.

 

Please post a post in ECS forum about the technical aspect of using ECS including:

• what it improved for you and how
• what was difficult to achieve in ECS
• what could be improved
• critical or negative feedback is useful

That's what @Joachim_Ante 's team needs to improve it, the hard things, to make it easier, to make it faster. New thread in ECS forum for it would be fantastic...

You can post as many times as you want. Real users of ECS are ❤

 

I feel now fake (non real user of ECS)

Yeah, such contribution would be fantastic to all of use.
Finally we got second SOLID and practical Example of ECS usability.

While you are probably right, on other hand, may lead to potential confusion, since project is outdated already.
So there is a risk for new comers, to get wrong from the start. Need add big disclaimer. Video however is very helpful.

 

Yeah thx for explanation, no problem it will be done I think for 1-2 weeks there will be my long article My wife and I just leave for vacation on September 15, so I finally have a little time, from programming, constant profiling and refactoring, to calmly and deliberately tell all my personal experience, difficulties and unconditional achievements associated with the transition to ECS. On next week I'm start preparing and structuring all what I want to tell

 

Amazing progress using ECS for production though. I don't know many people that brave

 

FYI, they, of course, did this many months ago Look to bottom of page
https://unity3d.com/ru/unity/features/job-system-ECS

 

Do you plan on creating some showcase thread or anything similar for projects using the new ECS? We are also using ECS for production now and I think many others will be glad to share their work too ECS has been awesome so far!

 

Link is fine, but don't think Russian version is appealing to everyone
Here is English version
