Struct playdate_controls::peripherals::Buttons

pub struct Buttons {
    pub current: PDButtons,
    pub pushed: PDButtons,
    pub released: PDButtons,
}
Expand description

Wrapped Buttons API.

Represents buttons state.

  • current indicates which buttons are currently down.
  • pushed and released reflects which buttons were pushed or released over the previous update cycle.

Note: at the nominal frame rate of 50 ms, fast button presses can be missed if you just poll the instantaneous state.

Fields§

§current: PDButtons

Indicating which buttons are currently down.

§pushed: PDButtons

Reflect which buttons were pushed over the previous update cycle. See struct doc.

§released: PDButtons

Reflect which buttons were released over the previous update cycle. See struct doc.
