registerMotionListener(
registerType: number,
listener: PluginEventListener
): PluginEventSubscription;
| 参数 | 类型 | 说明 |
|---|
registerType | number | 注册优先级：0 始终最前，1 普通排序，2 始终最后 |
listener | PluginEventListener | 事件回调对象，实现 onMsg(msg)；该方法内部等价于注册 motion_event 触摸移动事件监听。回调中的 msg 为 MotionEvent |
PluginEventSubscription：订阅对象，调用 remove() 会注销监听并移除本地订阅
import { PluginManager, type MotionEvent } from 'sn-plugin-lib';
/**
* 注册触摸移动事件监听的示例。

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;
