[ECS] Error in EntityManager with managed IComponentData
When I try to add a managed IComponentData to an entity like this:
World.DefaultGameObjectInjectionWorld.EntityManager.AddComponentData<StartingHandComponent>(entity, component);
I get a :
Entities = System.Runtime.InteropServices.MarshalDirectiveException: Type com.upgames.T9Aduel.StartingHandComponent which is passed to unmanaged code must have a StructLayout attribute.
This is just a managed Component that contains scriptable objects that are required to initialize my entites. It is not used anywhere else beside here:
NativeArray<Entity> entityWithStartingHands = World.DefaultGameObjectInjectionWorld.EntityManager.CreateEntityQuery(typeof(PlayerComponent)).ToEntityArray(Allocator.Temp);
NativeArray<GameStateComponent> gameStateComponents = World.DefaultGameObjectInjectionWorld.EntityManager.CreateEntityQuery(typeof(GameStateComponent)).ToComponentDataArray<GameStateComponent>(Allocator.Temp);
for (int i = 0; i < gameStateComponents.Length; ++i)
{
GameStateComponent gsComponent = gameStateComponents[i];
gsComponent.CurentStatus = GameStateComponentData.Status.Playing;
gameStateComponents[i] = gsComponent;
foreach (Entity entityWithStartingHand in entityWithStartingHands)
{
StartingHandComponent startingHandComponent = World.DefaultGameObjectInjectionWorld.EntityManager.GetComponentObject<StartingHandComponent>(entityWithStartingHand);
foreach (EntityData entityData in startingHandComponent.CardDatas)
{
Entity card = entityData.CreateEntity();
World.DefaultGameObjectInjectionWorld.EntityManager.AddComponentData(card, new ControllerComponent(entityWithStartingHand));
}
}
}
gameStateComponents.Dispose();
entityWithStartingHands.Dispose();
If I comment the line with the AddComponentData, I don't get an error in the EntityManager, though it appears that the AddComponentData with a managed type is supported.
Does anyone have an idea?
