Tutorial was such high tier I watched it even though I am not using Unity but still wanted to learn about multithreaded job systems

[BIMLOVEYJY]

after checking others vids about job system, this one is much more understanding than others

[qin]

thank you, I bought your courses even though I really don't need them, I just want to support you're made so good and easy understanding video! saved my a lot of time for DOTS learning

I think it's the first time I've seen a video with several thousands of views with _0_ dislikes.

[tony]

That was the best explanation so far. Thanks a lot.

[FREDO-pyti]

You've talent to explain complicate things !!!

Thinking of jobs as a struct(the value type) really helps out in the correct way on thinking about its requirements and life cycle. Ty.Cool

why do we need to dispose the native array when we provide an allocator.temp which tells it that it only last 1 frame like you said? If we do dispose it manually, why the allocator?

Hello first of all thank you for your great series of tutorial, you even created a useful playlist for DOTS that let's us go through each topic in a logical sequence step by step, they are also great because are up to date which is hard to find, also the visual aids you put are great and helpful.

I have a question regarding jobs. When doing an IJob it's pretty clear how to output data as you explained it.
If one decide to use SystemBase and use ScheduleParallel for a ForEach, how does one output a result/value?

I am getting the following error, do you know how to fix it :

A Native Collection has not been disposed, resulting in a memory leak. Allocated from:
Unity.Collections.NativeArray`1:.ctor(Byte[], Allocator)

UnityEngine.Networking.UnityWebRequest:SetupPost(UnityWebRequest, WWWForm)
UnityEngine.Networking.UnityWebRequest:Post(String, WWWForm)

Hello, I would like to understand one thing clear when we use the job system its blocks the main thread ( main thread has to wait until the job gets done) right? It's similar to using thread.join( ). I want to know what is the reason for blocking the main thread since it will make the application unresponsive? why they don't work concurrently? Thank you for the tutorials .

[gawer]

will this affect mobile gaming, like battery life and heat problem?

[ssmasrour]

Awesome, But!!! where is the source code link!? your code link help me to review whatever passed in your video once again

[Jigernaunt]

So in this video there are no answers to the questions of how actually job system achive parallel computation, when we need to use job system, what is the benifit of job system in comparision to thread pool. You just showed how to work with job API on a kinda useless example.
