PointerInfo

Defined in: types.ts:180

Read-only view of a tracked pointer. Returned from InputManager.getPointers and the per-pointer event hooks. Treat as immutable — fields reflect the pointer’s state at query time and are not retained between frames.

Properties

button

readonly button: number

Defined in: types.ts:205

The button whose state changed for the event this snapshot was delivered with: 0=left/primary, 1=middle, 2=right. -1 when not applicable — onPointerMove, pointercancel-driven up notifications, and query snapshots from InputManager.getPointers / getPointer.

Use this — not buttons — to filter by button inside an onPointerDown / onPointerUp listener: those listeners are notified before the edge is drained into buttons, so buttons does not yet reflect this event.
