bevy_dyn_component
Usage
Add dynamic_components_plugin
to your App
:
use bevy_dyn_component::prelude::*;
...
app.add_plugins(dynamic_components_plugin);
This initializes the component type registry needed for some of the unsafe sections. After that, you can use the dynamic_component
and insert_dynamic
APIs:
#[derive(Component)]
struct DynamicMarker;
let marker0 = world.dynamic_component::<DynamicMarker>();
world.entity_mut(e).insert_dynamic(marker0, DynamicMarker);
The component ID can also be used in the query builder API.
Future of this crate
Now that Bevy supports dynamic components, it's likely that this crate will soon be obsolete. In the longer term, many of the things you can do with this crate is easier with relations.
Examples
hello_world
Demonstrates basic usage of the library, how to create dynamic components with a layout matching an existing component, how to insert them into entities, and how to use them in the query builder API.
relations_at_home
Demonstrates a simple way of using dynamic components as janky fragmenting relations. In my opinion, it doesn't work well as a general-purpose relations pattern, but for specific cases, it can be handy.

Contribution
PRs welcome. If Bevy doesn't get good first-class support for this soon, I'll probably just keep updating this. It has missing APIs, for example, take_dynamic
. I probably won't be adding this until I need it in a project, but I also won't hesitate to merge it in if someone else wants to tackle it.
