Question How To Generic ISystem<Component>?

How does one overcome this error:

Code (CSharp):

1. ArgumentException: Unknown Type:`ECS.Systems.EffectTriggerSystem`1[ECS.Components.Effects.EffectSpeed]` All ComponentType must be known at compile time. For generic components, each concrete type must be registered with [RegisterGenericComponentType].

in:

Code (CSharp):

1. fixedStepSimulation.AddSystemToUpdateList(_world.CreateSystem<EffectTriggerSystem<EffectSpeed>>());

where system:

Code (CSharp):

1. public partial struct EffectTriggerSystem<T> : ISystem where T: unmanaged, IEffectTimed

where component:

Code (CSharp):

1. public struct EffectSpeed : IEffectTimed

where interface:

Code (CSharp):

1. public interface IEffect : IComponentData, IEnableableComponent

If I use this generic in EntityMamanger, like em.GetComponentData<T>(entity) - it works just fine, but throws when I try to use generic ISystem.

Code (CSharp):

1. [assembly: RegisterGenericComponentType(typeof(EffectTriggerSystem<EffectSpeed>))]

has no effect.

 

You can try a generic SystemBase for now. It worked in 0.50. Not sure if it works on 1.0. I'm still in the process of upgrading my project.

 

Atm. one of work around, but far from ideal as I have experienced, is to tap into Systems tate of ISystem.

 

Edit: Sorry, code posted was not really generic. Removed.

 

Does SystemBase work?

 

Yes

 

Generic IJobEntity soon so ?

 

In 1.0.10 I'm trying to use RegisterGenericSystemType like this

Code (CSharp):

1. [assembly: RegisterGenericSystemType(typeof(MySystem))]

And this gives me an error:

Code (CSharp):

1. Unity.Entities.CodeGen.EntitiesILPostProcessors: (0,0): error error DC3002: MySystem: [RegisterGenericJobType] requires an instance of a generic value type

But I don't have any generic job types

 

Is your system generic? Like MySystem<T>? Then you also need to declare that in the typeof.
If not, you just need to register the generic job and not the system.

 

I have this classes:

Code (CSharp):

1. public abstract partial MyBaseSystem<T> : SystemBase
2.  
3. public partial MyGameSystem : MyBaseSystem<GameState>

And I have tried both

Code (CSharp):

1. [assembly: RegisterGenericSystemType(typeof(MyBaseSystem<GameState>))]
2. [assembly: RegisterGenericSystemType(typeof(MyGameSystem))]

I don't have any generic jobs

 

RegisterGenericSystemType is only needed for ISystem.
SystemBase just needs an implementation and will work.

 

but if I remove RegisterGenericSystemType I get another error when calling AddSystemManaged:

Code (CSharp):

1. ArgumentException: Unknown Type:`MyGameSystem` All ComponentType must be known at compile time. For generic components, each concrete type must be registered with [RegisterGenericComponentType].

 

Hm, that's odd that this is thrown.
I have [DisableAutoCreation] on the base class. When implemented, the system is automatically added so I never need to call AddSystemManaged.
