Using Jobs inside GameObjectConversionSystem

Wondering if I should be using Jobs in my GameObjectConversionSystem. Have not seen anyone do this is there a reason for that?

 

I can't see why a job would not work, but why would you need it?

If your entity conversion is that expensive that even with the overhead a job is needed to optimise something is going really wrong. It doesn't make a lot of sense to me. GameObjectConversionSystem is converting a MonoBehaviour which you can't use in a job so are you copied components from a collection of MB into arrays then passing these to a job then copying them back to components?

I suspect what you're trying to do should probably be an editor script or within a monobehaviour validation and then just copied to the entity in the conversion because I doubt you're doing this at runtime? More likely in a subscene.

 

Blob generation is a common use case. See BaseShapeConversionSystem.cs in Unity.Physics for an example.

 

Im running into this because I can only create an additional entity one at a time. Remember my crazy conversion where I made an entity per vertex ? it for that. Problem is there is no real data in the gameObject just what shape to generate. I found if I do this in a separate system it become really hard to keep in sync with live link so Im trying to keep it all in the GameObjCoversionSys.

 

Will check it out thanks

 

That's kind of my point. You're doing this weird procedural generation in game object conversion. Does that really seem like the right location to do it?

You've had half a dozen posts detailing the problems your running into attempting this but from my outside perspective to me actual problem is just that you shouldn't be doing this.

Why not just store the data in the scene rather than generate it every conversion. From what I can tell, it's not even dynamic.

 

Originally i though I could get away from it being dynamic but I quickly ran into limitations. I will keep exploring different option and hopefully find a good solution. If anything ill keep learning as I go.
