# Objective - Add an `ExtractResourcePlugin` for convenience and consistency ## Solution - Add an `ExtractResourcePlugin` similar to `ExtractComponentPlugin` but for ECS `Resource`s. The system that is executed simply clones the main world resource into a render world resource, if and only if the main world resource was either added or changed since the last execution of the system. - Add an `ExtractResource` trait with a `fn extract_resource(res: &Self) -> Self` function. This is used by the `ExtractResourcePlugin` to extract the resource - Add a derive macro for `ExtractResource` on a `Resource` with the `Clone` trait, that simply returns `res.clone()` - Use `ExtractResourcePlugin` wherever both possible and appropriate
