Struct Touch 

pub struct Touch { /* private fields */ }

One finger on a touchscreen. Positions are in physical pixels, the same space as Input::mouse_pos. Obtain via Input::touches, Input::touches_started or Input::touches_ended.

Implementations

impl Touch

pub fn id(&self) -> u64

Stable for as long as the finger stays down; the platform may reuse it afterwards.

pub fn pos(&self) -> (f32, f32)

Where the finger is (for an ended touch: where it lifted).

pub fn start_pos(&self) -> (f32, f32)

Where the finger went down. Compare with Touch::pos to tell a tap from a swipe.

pub fn delta(&self) -> (f32, f32)

How far the finger moved this frame.
