### C# Example: Transition Arm Model Monobehaviour

Source: https://github.com/king-kloy/ar-project/blob/master/Library/PackageCache/com.unity.xr.legacyinputhelpers@2.0.2/Documentation~/ArmModels.md

This C# script implements an example monobehaviour for controlling the Transition Arm Model. It uses controller input (Right Trigger) to queue different arm models ('SwingArmModel' and 'PointerArmModel') and manages the transition timing. It requires references to the TransitionArmModel and the names of the arm models to transition between.

```csharp
public class ExampleTransitionArmModel : MonoBehaviour
{
    [SerializeField]
    public UnityEngine.XR.LegacyInputHelpers.TransitionArmModel transitionArmModel;

    [SerializeField]
    public string swingArmModelName = "SwingArmModel";

    [SerializeField]
    public string pointerArmModelName = "PointerArmModel";

    float timeToNextButtonPress = 0.0f;
    int currentArmModel = 0;

    // Update is called once per frame
    void Update()
    {
        // this uses the Right Trigger on the controller. to seed the input asset with this action, please
        // consult the XR Input Seeding documentation
        if (timeToNextButtonPress <= 0.0f && Input.GetButton("XRI_Right_TriggerButton"))
        {
            if(currentArmModel == 0)
            {
                transitionArmModel.Queue(swingArmModelName);
            }
            else
            {
                transitionArmModel.Queue(pointerArmModelName);
            }
            // flip which arm we're using
            currentArmModel = currentArmModel == 0 ? 1 : 0;
            timeToNextButtonPress = 1.0f; // wait a second before allowing another arm model to be queued
        }
        else
        {
            timeToNextButtonPress -= Time.deltaTime;
        }
    }
}
```

```csharp
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.EventSystems;
using System.Collections;

public class PanelManager : MonoBehaviour
{
    public Animator initiallyOpen;
    private int m_OpenParameterId;
    private Animator m_Open;
    private GameObject m_PreviouslySelected;

    const string k_OpenTransitionName = "Open";
    const string k_ClosedStateName = "Closed";

    public void OnEnable()
    {
        m_OpenParameterId = Animator.StringToHash(k_OpenTransitionName);
        if (initiallyOpen == null)
            return;
        OpenPanel(initiallyOpen);
    }

    public void OpenPanel(Animator anim)
    {
        if (m_Open == anim)
            return;

        anim.gameObject.SetActive(true);
        var newPreviouslySelected = EventSystem.current.currentSelectedGameObject;
        anim.transform.SetAsLastSibling();
        CloseCurrent();
        m_PreviouslySelected = newPreviouslySelected;
        m_Open = anim;
        m_Open.SetBool(m_OpenParameterId, true);

        GameObject go = FindFirstEnabledSelectable(anim.gameObject);
        SetSelected(go);
    }

    public void CloseCurrent()
    {
        if (m_Open == null)
            return;
        m_Open.SetBool(m_OpenParameterId, false);
        SetSelected(m_PreviouslySelected);
        StartCoroutine(DisablePanelDeleyed(m_Open));
        m_Open = null;
    }

    IEnumerator DisablePanelDeleyed(Animator anim)
    {
        bool closedStateReached = false;
        bool wantToClose = true;
        while (!closedStateReached && wantToClose)
        {
            if (!anim.IsInTransition(0))
                closedStateReached = anim.GetCurrentAnimatorStateInfo(0).IsName(k_ClosedStateName);
            wantToClose = !anim.GetBool(m_OpenParameterId);
            yield return new WaitForEndOfFrame();
        }
        if (wantToClose)
            anim.gameObject.SetActive(false);
    }

    private void SetSelected(GameObject go)
    {
        EventSystem.current.SetSelectedGameObject(go);
    }

    static GameObject FindFirstEnabledSelectable(GameObject gameObject)
    {
        GameObject go = null;
        var selectables = gameObject.GetComponentsInChildren<Selectable>(true);
        foreach (var selectable in selectables)
        {
            if (selectable.IsActive() && selectable.IsInteractable())
            {
                go = selectable.gameObject;
                break;
            }
        }
        return go;
    }
}

### AR Marker Tracking with Vuforia in Unity

Source: https://context7.com/king-kloy/ar-project/llms.txt

Manages AR marker tracking and the visibility of virtual objects in Unity using the Vuforia SDK. It registers a trackable event handler to detect when a marker is found or lost, and enables/disables renderers, colliders, and canvases accordingly.

```csharp
using UnityEngine;
using Vuforia;

public class DefaultTrackableEventHandler : MonoBehaviour, ITrackableEventHandler
{
    protected TrackableBehaviour mTrackableBehaviour;

    protected virtual void Start()
    {
        mTrackableBehaviour = GetComponent<TrackableBehaviour>();
        if (mTrackableBehaviour)
            mTrackableBehaviour.RegisterTrackableEventHandler(this);
    }

    public void OnTrackableStateChanged(
        TrackableBehaviour.Status previousStatus,
        TrackableBehaviour.Status newStatus)
    {
        if (newStatus == TrackableBehaviour.Status.DETECTED ||
            newStatus == TrackableBehaviour.Status.TRACKED ||
            newStatus == TrackableBehaviour.Status.EXTENDED_TRACKED)
        {
            Debug.Log("Trackable " + mTrackableBehaviour.TrackableName + " found");
            OnTrackingFound();
        }
        else if (previousStatus == TrackableBehaviour.Status.TRACKED &&
                 newStatus == TrackableBehaviour.Status.NO_POSE)
        {
            Debug.Log("Trackable " + mTrackableBehaviour.TrackableName + " lost");
            OnTrackingLost();
        }
    }

    protected virtual void OnTrackingFound()
    {
        var rendererComponents = GetComponentsInChildren<Renderer>(true);
        var colliderComponents = GetComponentsInChildren<Collider>(true);
        var canvasComponents = GetComponentsInChildren<Canvas>(true);

        foreach (var component in rendererComponents)
            component.enabled = true;
        foreach (var component in colliderComponents)
            component.enabled = true;
        foreach (var component in canvasComponents)
            component.enabled = true;
    }

    protected virtual void OnTrackingLost()
    {
        var rendererComponents = GetComponentsInChildren<Renderer>(true);
        var colliderComponents = GetComponentsInChildren<Collider>(true);
        var canvasComponents = GetComponentsInChildren<Canvas>(true);

        foreach (var component in rendererComponents)
            component.enabled = false;
        foreach (var component in colliderComponents)
            component.enabled = false;
        foreach (var component in canvasComponents)
            component.enabled = false;
    }
}

```csharp
using UnityEngine;

public class FootwearScript : MonoBehaviour
{
    public GameObject shoe;
    public GameObject sneaker;
    public GameObject slipper;
    public Transform PanelFootwears;

    // Usage: Attach to a GameObject and assign footwear prefabs in Inspector
    // Call these methods from UI buttons to display specific footwear in AR

    public void Shoe()
    {
        shoe.SetActive(true);
        sneaker.SetActive(false);
        slipper.SetActive(false);
        PanelFootwears.gameObject.SetActive(false);
    }

    public void Sneaker()
    {
        shoe.SetActive(false);
        sneaker.SetActive(true);
        slipper.SetActive(false);
        PanelFootwears.gameObject.SetActive(false);
    }

    public void Slipper()
    {
        shoe.SetActive(false);
        sneaker.SetActive(false);
        slipper.SetActive(true);
        PanelFootwears.gameObject.SetActive(false);
    }
}

### LeanFinger Touch Input System in C#

Source: https://context7.com/king-kloy/ar-project/llms.txt

The LeanFinger class in C# stores touch input data for gesture recognition and manipulation within Unity. It tracks finger properties like position, age, tap count, and swipe events. This system is crucial for handling user interactions in AR applications, enabling features like rotation, scaling, and selection.

```csharp
using UnityEngine;
using System.Collections.Generic;

namespace Lean.Touch
{
    public class LeanFinger
    {
        public int Index;              // Hardware ID of finger
        public float Age;              // Time active in seconds
        public bool Set;               // Currently touching screen
        public bool LastSet;           // Previous frame touch state
        public bool Tap;               // Just tapped
        public int TapCount;           // Number of taps
        public bool Swipe;             // Just swiped
        public float Pressure;         // Touch pressure (device-dependent)
        public Vector2 StartScreenPosition;
        public Vector2 LastScreenPosition;
        public Vector2 ScreenPosition;
        public bool StartedOverGui;    // Started touch over UI
        public List<LeanSnapshot> Snapshots;

        public bool IsActive
        {
            get { return LeanTouch.Fingers.Contains(this); }
        }

        public bool IsOverGui
        {
            get { return LeanTouch.PointOverGui(ScreenPosition); }
        }

        public bool Down
        {
            get { return Set == true && LastSet == false; }
        }

        public bool Up
        {
            get { return Set == false && LastSet == true; }
        }
    }
}

// Example Usage: Detecting Touch Gestures on AR Objects
/*
using Lean.Touch;
using UnityEngine;

public class ARObjectInteraction : MonoBehaviour
{
    void Update()
    {
        // Get all active touches
        var fingers = LeanTouch.Fingers;

        // Single finger drag to rotate
        if (fingers.Count == 1 && !fingers[0].IsOverGui)
        {
            var finger = fingers[0];
            if (finger.Set)
            {
                Vector2 delta = finger.ScreenPosition - finger.LastScreenPosition;
                transform.Rotate(Vector3.up, -delta.x * 0.5f, Space.World);
                transform.Rotate(Vector3.right, delta.y * 0.5f, Space.World);
            }
        }

        // Two finger pinch to scale
        if (fingers.Count == 2)
        {
            var fingerA = fingers[0];
            var fingerB = fingers[1];

            float lastDistance = Vector2.Distance(fingerA.LastScreenPosition, fingerB.LastScreenPosition);
            float currentDistance = Vector2.Distance(fingerA.ScreenPosition, fingerB.ScreenPosition);
            float scaleFactor = currentDistance / lastDistance;

            transform.localScale *= scaleFactor;
        }

        // Tap detection for selection
        foreach (var finger in fingers)
        {
            if (finger.Tap)
            {
                Debug.Log("Tapped at: " + finger.ScreenPosition);
                // Raycast to detect object selection
            }
        }
    }
}

### Application Exit Manager in C#

Source: https://context7.com/king-kloy/ar-project/llms.txt

The ApplicationManager class in C# provides a unified way to handle application exit across different platforms, including the Unity Editor and builds. It abstracts the platform-specific quitting mechanisms. This is essential for providing a consistent user experience when closing the application.

```csharp
using UnityEngine;

public class ApplicationManager : MonoBehaviour
{
    public void Quit()
    {
        #if UNITY_EDITOR
        UnityEditor.EditorApplication.isPlaying = false;
        #else
        Application.Quit();
        #endif
    }
}

// Example Usage:
// 1. Create GameObject "AppManager" and add ApplicationManager component
// 2. Create UI Button "Exit" or "Quit"
// 3. Link button OnClick() to ApplicationManager.Quit()
// 4. In Unity Editor: stops play mode
// 5. In Android build: closes application
// Best Practice: Add confirmation dialog before quitting
/*
using UnityEngine;
using UnityEngine.UI;

public class QuitWithConfirmation : MonoBehaviour
{
    public GameObject confirmationDialog;
    public ApplicationManager appManager;

    public void ShowQuitDialog()
    {
        confirmationDialog.SetActive(true);
    }

    public void ConfirmQuit()
    {
        appManager.Quit();
    }

    public void CancelQuit()
    {
        confirmationDialog.SetActive(false);
    }
}
*/

### Backpack Item Management in Unity C#

Source: https://context7.com/king-kloy/ar-project/llms.txt

Manages the display of different backpack models in Unity. It activates one backpack GameObject while deactivating others and closes the selection panel. Attach this script to a GameObject and assign prefabs in the Inspector, then call methods via UI buttons.

```csharp
using UnityEngine;

public class BackpackScript : MonoBehaviour
{
    public GameObject backpackOne;
    public GameObject backpackTwo;
    public GameObject backpackThree;
    public Transform PanelBackpacks;

    // Usage: Attach to a GameObject and assign backpack prefabs in Inspector
    // Call these methods from UI buttons to switch between backpack models

    public void BackpackOne()
    {
        backpackOne.SetActive(true);
        backpackTwo.SetActive(false);
        backpackThree.SetActive(false);
        PanelBackpacks.gameObject.SetActive(false);
    }

    public void BackpackTwo()
    {
        backpackOne.SetActive(false);
        backpackTwo.SetActive(true);
        backpackThree.SetActive(false);
        PanelBackpacks.gameObject.SetActive(false);
    }

    public void BackpackThree()
    {
        backpackOne.SetActive(false);
        backpackTwo.SetActive(false);
        backpackThree.SetActive(true);
        PanelBackpacks.gameObject.SetActive(false);
    }
}

### C# AR Model Visibility Control

Source: https://context7.com/king-kloy/ar-project/llms.txt

A Unity script to manage the visibility of multiple AR models. It dynamically adds an ActiveStateToggler component to each model and provides a method to toggle the visibility of a specific model by its index. This script is useful for controlling collections of AR objects within a scene.

```csharp
using UnityEngine;

public class ARModelController : MonoBehaviour
{
    public GameObject[] models;

    void Start()
    {
        // Add ActiveStateToggler to each model
        foreach (var model in models)
        {
            if (model.GetComponent<ActiveStateToggler>() == null)
            {
                model.AddComponent<ActiveStateToggler>();
            }
        }
    }

    public void ToggleModel(int index)
    {
        if (index >= 0 && index < models.Length)
        {
            models[index].GetComponent<ActiveStateToggler>().ToggleActive();
        }
    }
}
```
