onUpdate

Source: main.ts:66

Registers a callback function to receive calibrated rotation updates.

By default, this automatically initiates permission checks and begins listening unless startOnInit: false was passed in setConfig. Update frequency is throttled to RotationListenerConfig.pollingRate (default: 60 FPS).

Parameters

• callback ((update: RotationUpdate) => void) — Function invoked on each orientation tick with a RotationUpdate.

Returns

• void

Example

import { deviceRotation } from "web-orientation";

deviceRotation.onUpdate((update) => {
  const { x, y, z, w } = update.quaternion;
  console.log(`Quaternion: x=${x}, y=${y}, z=${z}, w=${w}`);
});
