Component OR matching in view

[jdtec01]

Hi,

Is it possible to create a view with a query for 'any of' / OR a list of components? eg. atm I am creating two identical views to do the same work, except one takes a PathAgent_FollowingPath and the other takes a PathAgent_PendingPath:

{auto view = Registry ().view<MovementGoal, const PathAgentGoal, const PathAgent_FollowingPath> ();
    for (auto [unitEntity, movementGoal, pathGoal]: view.each ())
    {
      movementGoal.Value = pathGoal.Value;
    }
  }
  {auto view = Registry ().view<MovementGoal, const PathAgentGoal, const PathAgent_PendingPath> ();
    for (auto [unitEntity, movementGoal, pathGoal]: view.each ())
    {
      movementGoal.Value = pathGoal.Value;
    }
  }

But what I'd really like is something like this that says you can have 'any' or either of the following components for the query to match. Basically a component OR :

{auto view = Registry ().view<MovementGoal, const PathAgentGoal> (entt::any<PathAgent_FollowingPath, PathAgent_PendingPath>);
   for (auto [unitEntity, movementGoal, pathGoal]: view.each ())
   {
     movementGoal.Value = pathGoal.Value;
   }
 }

Is it possible to do something like this in entt?

Uhm, no, actually it's not possible, mainly because there is no way to optimize it more than what you would do on the user side.
There is a plan to add policies to views for this kind of user side filters but they are not there yet. In any case, they'll be nothing more than syntactic sugar.

OK, thanks for the answer!
