UnityでLEAPのWebSocketサーバーjson受信

Unityで複数LEAPの可能性を探していたので、ひとつの再現方法をメモ

内容はjsonデータをUnityで見えるようにしている状態にしただけなので、活用できるかは未検証。。

返り値floatが本当に正しい値？など。。

LEAPの設定は下記

UnityでWEBSocketは下記を参考にしました

動作状態

スクリプト

WsLeap.cs

using UnityEngine;
using WebSocketSharp;

public class WsLeap : MonoBehaviour
{
  public WebSocket ws;
  public string url = "ws://192.168.1.1:6437/";//環境ごとに変更
  public float currentFrameRate;
  public Devices[] devices;
  public Hands[] hands;
  public int id;
  public Pointables[] pointables;
  public int timestamp;
  public void RecvText(string text)
  {
    string json = text.ToString();
    LeapJson jsonData = new LeapJson();
    JsonUtility.FromJsonOverwrite(json, jsonData);

    currentFrameRate = jsonData.currentFrameRate;
    devices = jsonData.devices;
    hands = jsonData.hands;
    id = jsonData.id;
    pointables = jsonData.pointables;
    timestamp = jsonData.timestamp;
  }
  public void RecvClose()
  {
  }

  void Start()
  {
    ws = new WebSocket(url);
    ws.Connect();
    ws.OnMessage += (sender, e) => RecvText(e.Data);
    ws.OnClose += (sender, e) => RecvClose();
  }
}
