Struct nannou::ui::input::Touch

pub struct Touch {
    pub phase: Phase,
    pub id: Id,
    pub xy: [f64; 2],
}

Represents a touch interaction.

Each time a user touches the surface with a new finger, a new series of Touch events Start, each with a unique identifier.

For every Id there should be at least 2 events with Start and End (or Cancelled) Phases.

A Start input received with the same Id as a previously received End does not indicate that the same finger was used. Ids are only used to distinguish between overlapping touch interactions.

Fields

phase: Phase

The stage of the touch interaction.

id: Id

A unique identifier associated with the source of the touch interaction.

xy: [f64; 2]

The location of the touch on the surface/screen. See Input docs for information on the co-ordinate system.
