3.4.2版本 用键盘控制移动的问题

Creator 3.x
#1

已经能够获取到键盘事件了。但是怎么赋予对应的移动呢？ 应该放在update(dt:number)里吗？
网上看的教程都是2 3年前的了QAQ
import { _decorator, Component, input, Input, EventKeyboard, KeyCode, Vec3, RigidBody, TERRAIN_MAX_LEVELS, SphereCollider, macro } from ‘cc’;

const { ccclass } = _decorator;

@ccclass(“Example”)

export class Example extends Component {

onLoad () {

    input.on(Input.EventType.KEY_DOWN, this.onKeyDown, this);

    input.on(Input.EventType.KEY_UP, this.onKeyUp, this);

}

onDestroy () {

    input.off(Input.EventType.KEY_DOWN, this.onKeyDown, this);

    input.off(Input.EventType.KEY_UP, this.onKeyUp, this);

}

onKeyDown (event: EventKeyboard) {

    switch(event.keyCode) {

            console.log('向左');

    }

    rb?.setLinearVelocity(lv);

   

}

}

笨逼终于有了一点点进步了！！！！！

#3 
    Vec3.transformQuat(lv,lv,this.node.getRotation());//可以改为向前走的
    rb?.setLinearVelocity(lv);
