bevy_basic_interaction

This crate provides an InteractionPlugin which enables a basic interaction system.

This plugin is mostly for my own internal use, but feel free to use it or contribute if you feel like it.

Compatibility

Installation

If enough people (like literally 1 person) want this on crates.io I'll consider putting it up there, but for now just add the GitHub URL to your Cargo.toml:

[dependencies.bevy_basic_interaction]
git = "https://git.exvacuum.dev/bevy_basic_interaction"

Usage

This plugin works based on a system of Interactors and Interactables. Interactors maintain a list of "target" Interactables which are in range of the interactor (based on a maximum distance defined in the interactable). The user can invoke an InteractorFiredEvent, passing the Entity with an Interactor component on it, and the plugin will automatically determine which interactables to invoke a corresponding InteractionEvent for.

In main function:

use bevy::prelude::*;
use bevy_basic_interaction::InteractionPlugin;

fn main() {
    App::new()
        // ...
        .add_plugins(InteractionPlugin)
        // ...
        .run();
}

Raising an interactor event (entity must be an entity with both an Interactor and a GlobalTransform component):

// ...
event_writer.send(InteractorFiredEvent(entity));
// ...

Handling an interaction event:

// ...
for InteractionEvent { interactable, .. } in event_reader.read() {
    let interactable = interactable_query.get(interactable).unwrap();
    // Do something with interactable here...
}
// ...
