Interaction

All widgets provided by Famiq have Interaction component attached by default. That means all those widgets will emit FaInteractionEvent to bevy's EventReader with either Pressed, Hovered or None.

pub struct FaInteractionEvent {
    pub entity: Entity,
    pub widget_id: Option<String>,
    pub interaction: Interaction,
    pub widget: WidgetType,
}

Available widget types

pub enum WidgetType {
    Root,
    Button,
    Container,
    Text,
    FpsText,
    TextInput,
    ListView,
    ListViewItem,
    Selection,
    SelectionChoice,
    Circular,
    Modal,
    Image
}

Handle interaction

You can write a bevy system to handle Famiq’s widgets interaction.

fn handle_button_press_system(mut events: EventReader<FaInteractionEvent>) {
    for e in events.read() {
        if e.widget == WidgetType::Image && e.interaction == Interaction::Hovered {
            // make sure this works only with widgets that have id provided
            if let Some(id) = e.widget_id.as_ref() {
                match id.as_str() {
                    "#image-one-id" => {
                        // do something
                    },
                    "#image-two-id" => {
                        // do something
                    }
                    _ => ()
                }
            }
        }
    }
}
