# 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 the `ReflectComponent` struct, as well as a `pub fn remove_component(&self, world: &mut World, entity: Entity)` to call that function in `remove_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): https://github.com/gschup/bevy_ggrs/blob/6c003f86f1993bcbb21c180fab2e8ef664b7f7c9/src/world_snapshot.rs#L133

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_componentfield to theReflectComponentstruct, 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):
