GazeGestureManager 만들기

C# 스크립트 작성

Project 패널에서 Scripts를 선택

마우스 오른쪽 버튼을 클릭하고 "Create"- "C# Script"를 선택하십시오.

이름을 GazeGestureManager로 변경

생성 된 GazeGestureManager를 Hierarchy 패널의 OrigamiCollection 객체에 놓습니다

"GazeGestureManager"를 두 번 클릭 (-> Visual Studio 시작)

C# 스크립트 편집

GazeGestureManager.cs

using UnityEngine;
using UnityEngine.VR.WSA.Input;

public class GazeGestureManager : MonoBehaviour
{
    public static GazeGestureManager Instance { get; private set; }

    // Represents the hologram that is currently being gazed at.
    public GameObject FocusedObject { get; private set; }

    GestureRecognizer recognizer;

    // Use this for initialization
    void Start()
    {
        Instance = this;

        // Set up a GestureRecognizer to detect Select gestures.
        recognizer = new GestureRecognizer();
        recognizer.TappedEvent += (source, tapCount, ray) =>
        {
            // Send an OnSelect message to the focused object and its ancestors.
            if (FocusedObject != null)
            {
                FocusedObject.SendMessageUpwards("OnSelect");
            }
        };
        recognizer.StartCapturingGestures();
    }

    // Update is called once per frame
    void Update()
    {
        // Figure out which hologram is focused this frame.
        GameObject oldFocusObject = FocusedObject;

        // Do a raycast into the world based on the user's
        // head position and orientation.
        var headPosition = Camera.main.transform.position;
        var gazeDirection = Camera.main.transform.forward;

        RaycastHit hitInfo;
        if (Physics.Raycast(headPosition, gazeDirection, out hitInfo))
        {
            // If the raycast hit a hologram, use that as the focused object.
            FocusedObject = hitInfo.collider.gameObject;
        }
        else
        {
            // If the raycast did not hit a hologram, clear the focused object.
            FocusedObject = null;
        }

        // If the focused object changed this frame,
        // start detecting fresh gestures again.
        if (FocusedObject != oldFocusObject)
        {
            recognizer.CancelGestures();
            recognizer.StartCapturingGestures();
        }
    }
}

GestureRecognizer

Manager class with API for recognizing user gestures.

GestureRecognizer.TappedEvent

Occurs when a Tap gesture is recognized.

GestureRecognizer.StartCapturingGestures

Call to begin receiving gesture events on this recognizer. No events will be received until this method is called.

GestureRecognizer.CancelGestures

Cancels any pending gesture events. Additionally this will call StopCapturingGestures.

GameObject.SendMessageUpwards

게임 오브젝트와 부모 (부모, 심지어 부모 ...)에 첨부 된 모든 MonoBehaviour에서 methodName이라는 이름의 메서드를 호출합니다.

ShpereCommands 만들기

C# 스크립트 작성

Project 패널에서 Scripts를 선택

마우스 오른쪽 버튼을 클릭하고 "Create"- "C# Script"를 선택하십시오.

이름을 SphereCommands로 변경

생성 된 ShpereCommands를 Hierarchy 패널의 OrigamiCollection - Sphere1 및 Spere2 객체에 놓습니다.

ShpereCommands를 두 번 클릭 (-> Visual Studio 시작)

SphereCommands.cs

using UnityEngine;

public class SphereCommands : MonoBehaviour
{
    // Called by GazeGestureManager when the user performs a Select gesture
    void OnSelect()
    {
        // If the sphere has no Rigidbody component, add one to enable physics.
        if (!this.GetComponent<Rigidbody>())
        {
            var rigidbody = this.gameObject.AddComponent<Rigidbody>();
            rigidbody.collisionDetectionMode = CollisionDetectionMode.Continuous;
        }
    }
