registerMotionListener

registerMotionListener(
  registerType: number,
  listener: PluginEventListener
): PluginEventSubscription;

Parameters

Parameter	Type	Description
`registerType`	`number`	Registration priority: `0` always first, `1` normal order, `2` always last
`listener`	`PluginEventListener`	Event callback object that implements `onMsg(msg)`. Internally, this method is equivalent to registering a `motion_event` touch move event listener. The callback `msg` is `MotionEvent`

Returns

PluginEventSubscription: subscription object. Calling remove() unregisters the listener and removes the local subscription.

Example

import { PluginManager, type MotionEvent } from 'sn-plugin-lib';

/**
 * Example: register a touch move event listener.
 */
export async function exampleRegisterMotionListener() {
  const sub = PluginManager.registerMotionListener(1, {
    onMsg(msg) {
      const motion = msg as MotionEvent;
      console.log('touch move pointer count:', motion.pointerCount);
      console.log('first pointer id:', motion.pointers[0]?.pointerId);
    },
  });
  return sub;
}
