Expand description

Single touch point state

Fields§

§id: TouchId

Unique identifier for this touch

§pos: (f64, f64)

Current position in screen coordinates

§prev_pos: (f64, f64)

Previous position (for calculating delta)

§force: Option<f64>

Force/pressure (0.0 to 1.0, optional depending on hardware)

§start_time: f64

Time when this touch started (in seconds)
