Where is the bootstrap in twostickspure?

The only mono I see is the settings, how does this scene starts?

 

This?

 

I believe the key is this attribute:
https://github.com/Unity-Technologi...Shooter/Pure/Scripts/TwoStickBootstrap.cs#L23

https://docs.unity3d.com/ScriptReference/RuntimeInitializeOnLoadMethodAttribute-ctor.html

 

This script isn't in the scene so how does this attribute knows that it's this scene and not another one?

 

It doesn't. It'll run in any scene. But for pure ECS having multiple scenes often doesn't make much sense except to load in data asynchronously.

 

There are 4 bootstrap scripts in the sample project, so all 4 run when I press play in the boid scene?

 

As long as they have the RuntimeInitializeOnLoadMethodAttribute yes. You can have as many bootstraps as you want really. I use one to initialize network systems and another one for combat systems.

 

Are there benefits to using this vs using awake?

 

I guess the main point is to not have to use a GameObject to initialize but I don't think there's a specific pro or con.

If you want to go full Pure ECS then you wouldn't want to use a GO right?

You can also start initializing before the scene loads.

 

Thanks.
I'll use Awake and multi scene, I am sure there is a benefit in term of bootup time but I like seeing the entry point to my scene logic.
