Objective

From my understanding, although resources are not meant to be created and removed at every frame, they are still meant to be created dynamically during the lifetime of the App.
But because the extract_resource API does not allow optional resources from the main world, it's impossible to use resources in the render phase that were not created before the render sub-app itself.

Solution

Because the ECS engine already allows for system parameters to be Option<Res>, it just had to be added.


Changelog

  • Changed

    • extract_resource now takes an optional main world resource
  • Fixed

    • ExtractResourcePlugin doesn't cause panics anymore if the resource is not already inserted

Alright, I like this. It should increase the flexibility / robustness of resource extraction without adding meaningful overhead or complexity.
