Enum bevy::ui::Interaction

pub enum Interaction {
    Clicked,
    Hovered,
    None,
}

Describes what type of input interaction has occurred for a UI node.

This is commonly queried with a Changed<Interaction> filter.

Updated in ui_focus_system.

If a UI node has both Interaction and ComputedVisibility components, Interaction will always be Interaction::None when ComputedVisibility::is_visible() is false. This ensures that hidden UI nodes are not interactable, and do not end up stuck in an active state if hidden at the wrong time.

Note that you can also control the visibility of a node using the Display property, which fully collapses it during layout calculations.

Variants

Clicked

The node has been clicked

Hovered

The node has been hovered over

None

Nothing has happened
