Scene mangement with builtin pipeline

[mathisloge]

Hi,

I'm quite new to flecs.
I was wondering on how to combine the builtin pipeline with the scene_management example from here: https://github.com/SanderMertens/flecs/blob/master/examples/cpp/game_mechanics/scene_management/src/main.cpp

What I've tried is to use the given query from the documentation and add a .without<MenuScene> resulting in

    flecs::entity game = ecs.pipeline()
                             .with(flecs::System)
                             .with(flecs::Phase)
                             .cascade(flecs::DependsOn)
                             .without(flecs::Disabled)
                             .up(flecs::DependsOn)
                             .without(flecs::Disabled)
                             .up(flecs::ChildOf)
                             .without<GameScene>()
                             .build();

However, now the systems tagged with OnStart are running constantly.

Is there an easy way to use the builtin pipeline for each scene but with the .without<Scene>() tag?

Try adding this to the query:

.without(flecs::DependsOn, flecs::OnStart).self().up(flecs::DependsOn)

That should prevent OnStart systems from getting matched, which is also what the builtin pipeline does.
