InvalidOperationException: Trying to get iterator for Components.Units.OwnerControlGroup but the required component type was not declared in the EntityGroup.
I’ve tried ComponentType.ReadOnly, and ReadWrite with the same result.
GetEntityQuery fails the same way.
OwnerControlGroup is defined as this:
using Unity.Entities;
namespace Components.Units {
public struct OwnerControlGroup : ISharedComponentData {
public int ControlId;
public OwnerControlGroup(int controlId) {
ControlId = controlId;
}
}
}
Units do have a shared component attached to them.
Where are you calling this code from? Usually you use GetFilter in OnCreate, and then SetFilter in OnUpdate. If used otherwise I doubt it would cause issues but maybe?
A complete shot in the dark, but maybe the constructor is throwing things off? Unity creates a default shared component of your type, and maybe the lack of a parameter-less constructor is throwing off this process. I would add one, and if that doesn’t work, try removing the constructor. When doing the latter, if you have a lot of new OwnerControlGroup(ID) lines, you could do a Find/Replace and switch them to new OwnerControlGroup { ControlID = ID}.
Just some ideas with nothing substantial to back them up.
Show full code, some mistakes on your side, cause SetFilter works fine
