# Objective fixes #17896 ## Solution Change ChildOf ( Entity ) to ChildOf { parent: Entity } by doing this we also allow users to use named structs for relationship derives, When you have more than 1 field in a struct with named fields the macro will look for a field with the attribute #[relationship] and all of the other fields should implement the Default trait. Unnamed fields are still supported. When u have a unnamed struct with more than one field the macro will fail. Do we want to support something like this ? ```rust #[derive(Component)] #[relationship_target(relationship = ChildOf)] pub struct Children (#[relationship] Entity, u8); ``` I could add this, it but doesn't seem nice. ## Testing crates/bevy_ecs - cargo test ## Showcase ```rust use bevy_ecs::component::Component; use bevy_ecs::entity::Entity; #[derive(Component)] #[relationship(relationship_target = Children)] pub struct ChildOf { #[relationship] pub parent: Entity, internal: u8, }; #[derive(Component)] #[relationship_target(relationship = ChildOf)] pub struct Children { children: Vec<Entity> }; ``` --------- Co-authored-by: Tim Overbeek <oorbecktim@Tims-MacBook-Pro.local> Co-authored-by: Tim Overbeek <oorbecktim@c-001-001-042.client.nl.eduvpn.org> Co-authored-by: Tim Overbeek <oorbecktim@c-001-001-059.client.nl.eduvpn.org> Co-authored-by: Tim Overbeek <oorbecktim@c-001-001-054.client.nl.eduvpn.org> Co-authored-by: Tim Overbeek <oorbecktim@c-001-001-027.client.nl.eduvpn.org> |
