Laser_pointer_trigger NPM

laser_pointer_trigger

What

use to detect object 3d and UI on VR,MR,..

Requirement

UniRx
.Net 4.x

Install

yarn add laser_pointer_trigger

Usage

Detect object 3D: - On folder Prefabs drop LaserPointerHandle to the scene - Find component LaserLine and setting flied layer mask target want to detect object - On object want to detect set layer mask, add collider (box collider,...) and add script below
```
using UniRx.Triggers;
using UnityEngine;
using UnityEngine.EventSystems;
using UniRx;
```

public class Sample : UIBehaviour {

protected override void Start()
{
    this.OnLaserTriggerEnterAsObservable()
        .Subscribe(message => Debug.Log(message.Point));

    this.OnLaserTriggerStayAsObservable()
        .Subscribe(message => Debug.Log(message.Point));

    this.OnLaserTriggerExitAsObservable()
        .Subscribe(message => Debug.Log(message.Point));

    this.OnLaserTriggerAsObservable()
        .Subscribe(message => Debug.Log(message.Point));
}

}

* Detect UI 2D:
    - On Canvas add component LaserPoiterRayCaster
    - On Object EventSystem replace StandaloneInputModule by LaserPointerInputModule
    - In this can use every event (OnPointerDown, OnPointerUp, OnDrag, ...) by laser

```csharp
using UniRx.Triggers;
using UnityEngine;
using UnityEngine.EventSystems;
using UniRx;

public class TestUI : UIBehaviour
{
    protected override void Start()
    {
        this.OnPointerDownAsObservable()
            .Subscribe(_ => Debug.Log("pointer down"));

        this.OnDragAsObservable()
            .Subscribe(_ => Debug.Log("drag"));
    }
}

Active trigger:
- Methob ActiveTrigger() emit OnPointerDown() and OnLaserTriggerAsObservale()
- Methob ExitTrigger() emit OnPointerUp()

This template code:

using LaserPointerTrigger;
using UniRx;
using UnityEngine;

public class TestLaserPointer : MonoBehaviour
{
    private void Start()
    {
        Observable.EveryUpdate()
            .Where(_ => Input.GetMouseButtonDown(0))
            .Subscribe(_ => GetComponent<LaserPointerHandler>().ActiveTrigger());

        Observable.EveryUpdate()
            .Where(_ => Input.GetMouseButtonUp(0))
            .Subscribe(_ => GetComponent<LaserPointerHandler>().ExitTrigger());
    }
}
