nullable generics type function in C# Unity

问题

以下是您提供的代码的翻译部分：

  1. 我正在为Unity DOTS中的空间分割系统工作。
  2. 示例函数如下：
  4. partial struct CharCopyJob : IJobEntity
  5. {
  6.     public NativeList<Entity> Entities;
  7.     public NativeList<CharacterControllerComponent> Bodies;
  8.     public NativeList<LocalTransform> Transforms;
  9.     public NativeList<AICharacterStateData> CharacterStates;
  10.     public NativeList<AIInteractionSignalData> Signals;
  12.     void Execute(Entity entity, in CharacterControllerComponent body, in LocalTransform transform, in AICharacterStateData state, in AIInteractionSignalData signal)
  13.     {
  14.         Entities.Add(entity);
  15.         Bodies.Add(body);
  16.         Transforms.Add(transform);
  17.         CharacterStates.Add(state);
  18.         Signals.Add(signal);
  19.         log(Entities.Length);
  20.     }
  21. }

但是正如您可以想象的那样，对于每种类型的实体，我都必须重新编写此函数（例如，角色、武器等）。

我正在尝试编写一个更通用的作业，用于此目的：

  1. partial struct CopyJob<A, B, C, D, E, F, G, H, I> : IJobEntity
  2.     where A : unmanaged, IComponentData
  3.     where B : unmanaged, IComponentData
  4.     where C : unmanaged, IComponentData
  5.     where D : unmanaged, IComponentData
  6.     where E : unmanaged, IComponentData
  7.     where F : unmanaged, IComponentData
  8.     where G : unmanaged, IComponentData
  9.     where H : unmanaged, IComponentData
  10.     where I : unmanaged, IComponentData
  11. {
  12.     public NativeList<A> al;
  13.     public NativeList<B> bl;
  14.     public NativeList<C> cl;
  15.     public NativeList<D> dl;
  16.     public NativeList<E> el;
  17.     public NativeList<F> fl;
  18.     public NativeList<G> gl;
  19.     public NativeList<H> hl;
  20.     public NativeList<I> il;
  22.     void Execute(Entity entity, A a, B b, C c, D d, E e, F f, G g, H h, I i)
  23.     {
  24.         if (typeof(A) == typeof(Null))
  25.             al.Add(a);
  26.         if (typeof(B) == typeof(Null))
  27.             bl.Add(b);
  28.         if (typeof(C) == typeof(Null))
  29.             cl.Add(c);
  30.         if (typeof(D) == typeof(Null))
  31.             dl.Add(d);
  32.         if (typeof(E) == typeof(Null))
  33.             el.Add(e);
  34.         if (typeof(F) == typeof(Null))
  35.             fl.Add(f);
  36.         if (typeof(G) == typeof(Null))
  37.             gl.Add(g);
  38.         if (typeof(H) == typeof(Null))
  39.             hl.Add(h);
  40.         if (typeof(I) == typeof(Null))
  41.             il.Add(i);
  42.     }
  43. }

这是我想出来的，但由于NULL不能是unmanaged类型，因此无法正常工作。

如果您有任何建议，将不胜感激。

I am working on a system for spatial partitioning in unity dots and currently.

the workin example function looks something like this

  1. partial struct CharCopyJob : IJobEntity
  2.     {
  3.         public NativeList&lt;Entity&gt; Entities;
  4.         public NativeList&lt;CharacterControllerComponent&gt; Bodies;
  5.         public NativeList&lt;LocalTransform&gt; Transforms;
  6.         public NativeList&lt;AICharacterStateData&gt; CharacterStates;
  7.         public NativeList&lt;AIInteractionSignalData&gt; Signals;
  9.         void Execute(Entity entity, in CharacterControllerComponent body, in LocalTransform transform, in AICharacterStateData state, in AIInteractionSignalData signal)
  10.         {
  11.             Entities.Add(entity);
  12.             Bodies.Add(body);
  13.             Transforms.Add(transform);
  14.             CharacterStates.Add(state);
  15.             Signals.Add(signal);
  16.             log(Entities.Length);
  17.         }
  18.     }

but as you can imagine, for every kind of entity i have to rewrite this function ( i.e. char, weapons etc).

I am trying to write a more generic job for this purpose

  1. partial struct CopyJob&lt;A,B,C,D,E,F,G,H,I&gt; : IJobEntity 
  2.         where A : unmanaged, IComponentData
  3.         where B : unmanaged, IComponentData
  4.         where C : unmanaged, IComponentData 
  5.         where D : unmanaged, IComponentData
  6.         where E : unmanaged, IComponentData 
  7.         where F : unmanaged, IComponentData
  8.         where G : unmanaged, IComponentData
  9.         where H : unmanaged, IComponentData
  10.         where I : unmanaged, IComponentData
  11.     {
  12.         public NativeList&lt;A&gt; al;
  13.         public NativeList&lt;B&gt; bl;
  14.         public NativeList&lt;C&gt; cl;
  15.         public NativeList&lt;D&gt; dl;
  16.         public NativeList&lt;E&gt; el;
  17.         public NativeList&lt;F&gt; fl;
  18.         public NativeList&lt;G&gt; gl;
  19.         public NativeList&lt;H&gt; hl;
  20.         public NativeList&lt;I&gt; il;
  22.         void Execute(Entity entity, A a, B b, C c, D d, E e, F f, G g, H h, I i)
  23.         {
  24.             if(typeof(A) == typeof(Null))
  25.                 al.Add(a);
  26.             if(typeof(B) == typeof(Null))
  27.                 bl.Add(b);
  28.             if(typeof(C) == typeof(Null))
  29.                 cl.Add(c);
  30.             if(typeof(D) == typeof(Null))
  31.                 dl.Add(d);
  32.             if(typeof(E) == typeof(Null))
  33.                 el.Add(e);
  34.             if(typeof(F) == typeof(Null))
  35.                 fl.Add(f);
  36.             if(typeof(G) == typeof(Null))
  37.                 gl.Add(g);
  38.             if(typeof(H) == typeof(Null))
  39.                 hl.Add(h);
  40.             if(typeof(I) == typeof(Null))
  41.                 il.Add(i);
  42.         }
  43.     }

this is what i came up with but it is not working as NULL can not be unmanaged.

Any suggestions would be appreciated.

  1. Allocator allocator = Allocator.Temp;
  3. var query = EntityManager.CreateEntityQuery(
  4.     	ComponentType.ReadOnly<CharacterControllerComponent>()
  5.     ,	ComponentType.ReadOnly<LocalTransform>()
  6.     ,	ComponentType.ReadOnly<AICharacterStateData>()
  7.     ,	ComponentType.ReadOnly<AIInteractionSignalData>()
  8. );    
  9. var entities = query.ToEntityListAsync(allocator, out var h0);
  10. var bodies = query.ToComponentDataListAsync<CharacterControllerComponent>(allocator, out var h1);
  11. var transforms = query.ToComponentDataListAsync<LocalTransform>(allocator, out var h2);
  12. var characterStates = query.ToComponentDataListAsync<AICharacterStateData>(allocator, out var h3);
  13. var signals = query.ToComponentDataListAsync<AIInteractionSignalData>(allocator, out var h4);
  14.     	
  15. JobHandle copyJobHandle = JobHandle.CombineDependencies(
  16. 	new NativeList<JobHandle>(Allocator.Temp) { h0, h1, h2, h3, h4 }
  17. );
英文:

You do not need to implement what is there already.

  1. Allocator allocator = Allocator.Temp;
  3. var query = EntityManager.CreateEntityQuery(
  4.     	ComponentType.ReadOnly&lt;CharacterControllerComponent&gt;()
  5.     ,	ComponentType.ReadOnly&lt;LocalTransform&gt;()
  6.     ,	ComponentType.ReadOnly&lt;AICharacterStateData&gt;()
  7.     ,	ComponentType.ReadOnly&lt;AIInteractionSignalData&gt;()
  8. );    
  9. var entities = query.ToEntityListAsync( allocator , out var h0 );
  10. var bodies = query.ToComponentDataListAsync&lt;CharacterControllerComponent&gt;( allocator , out var h1 );
  11. var transforms = query.ToComponentDataListAsync&lt;LocalTransform&gt;( allocator , out var h2 );
  12. var characterStates = query.ToComponentDataListAsync&lt;AICharacterStateData&gt;( allocator , out var h3 );
  13. var signals = query.ToComponentDataListAsync&lt;AIInteractionSignalData&gt;( allocator , out var h4 );
  14.     	
  15. JobHandle copyJobHandle = JobHandle.CombineDependencies(
  16. 	new NativeList&lt;JobHandle&gt;(Allocator.Temp){ h0 , h1 , h2 , h3 , h4 }
  17. );

我最终创建了多个系统以满足各种用途。
它还有助于简化不同的系统。

英文:

I ended up creating multiple systems for every use.
It also helps in simplifying different systems.
