Unite Austin 2017 - Writing High Performance C# Scripts - Question about talk

I watched the Talk and have some Questions so far:

In this image, is this a mistake? Is the "prefab" meant to be the "minionPrefab" ? Otherwise I don't understand what's happening.




And here, deleting one-bye-one, you call Destroy on the entity. But deleting all entities in batch doesn't make sense to me, if it's not a typo. I expect the batched call to receive the entityArray. Like in C and C++, you can delete an array like this using delete[] insead of delete.

pt = new MyClass[3];

delete[] pt;

I am really interested in the talk and it's quite long, going into detail. I want to fully understand it so please excuse my nitpicky questions.

 

Without actually testing, yes it looks like it should be prefab or minionprefab (both should be the same). Does it work for you? Same with your last question, does it work for you?

 

Haven't tried it yet. Is the "nordeus rts tech demo" available somewhere? Or is there an example Project?

 

If you want to keep up to date on the job system and the ECS system, there's a lot of info that keeps popping up in the 2018 beta forums. The ECS system is not available in any betas yet, but somebody from Unity (forget who) said that it would get it's own beta forum once it can be tested.

For your question, it looks like a bug in the code. @Joachim_Ante would know for sure, since he's the one that held the talk!

 

Answering myself: the demo is now available :

https://github.com/Unity-Technologies/UniteAustinTechnicalPresentation/blob/master/README.md

it is stripped down a bit, to avoid releasing assets owned by nordeus. But it is a great resource to lern more about ECS.
