Objective
While implementing a plugin for my rollback networking library, I needed to load/save parts of the world. For this, I made a WorldSnapshot that works quite like the current DynamicScene. Using a TypeRegistry to register component types I want to save/load and then using ReflectComponents methods to add or apply components of the given types.
However, I noticed there is no method to remove components from entities through the ReflectComponent.
Solution
I added a
remove_component
field to theReflectComponent
struct, as well as apub fn remove_component(&self, world: &mut World, entity: Entity)
to call that function inremove_component
. This follows exactly the same pattern all other methods/fields in this struct look like.This is an example how it could be used (at least how I would use it):
