        if (Physics.Raycast(_pointerRay, out _hit))

        }
        else
        {
            _hitObj = null;
        }
    }
}

Description:

• OnCollisionEnter(Collision collision):
  • If the colliding object has the right name, load the scene accordingly

Notes:

• Need to test this again
• collider is on the button

Button handler code refinement

Rewrote code in ButtonHandler.cs to be non-hardcoded

Code Changes + Description

ButtonHandler.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.SceneManagement;

public class ButtonHandler : MonoBehaviour
{
    public GameObject pointerOrigin;

    private Ray _pointerRay;
    private RaycastHit _hit;
    private GameObject _hitObj;
    private bool _doRaycast = false;

    private void Update()
    {
        if (OVRInput.GetDown(OVRInput.RawButton.RIndexTrigger)){
            //if the right index trigger is pressed, set hit obj to null and do raycast
            _hitObj = null;
            _doRaycast = true;
        }
        else {
            _doRaycast = false;
        }

        //hit obj handling
        if (_hitObj != null && _hitObj.GetComponentInChildren<Button>() != null) {
            char[] remove = { 'b', 't', 'n' };
            SceneManager.LoadScene(_hit.collider.name.TrimStart(remove));
        }
    }

    private void FixedUpdate()
    {
        if (_doRaycast)
        {
            //casting from the main camera to the point on screen where the mouse is
            _pointerRay = new Ray(pointerOrigin.transform.position, pointerOrigin.transform.forward);

            if (Physics.Raycast(_pointerRay, out _hit))
            {
                //if the point where the player click contains a gameobject
                _hitObj = _hit.transform.gameObject;
            }
        }
    }
}

Description: Buttons in the scene that change scenes should be named btnSCENENAME (e.g btnMyScene)

• Update():
  • If the right index trigger is pressed once, set _hitObj to null before setting _doRaycast to true
  • If the _hitObj is not null and has the Button component (if the object is not null and is a button), remove the characters "b", "t" and "n" from the name of the object and load the scene with the same name as the edited string
• FixedUpdate():
  • When _doRaycast is set to true, cast a ray from the right controller in the +Z direction of the pointer
  • If the raycast hits something, set _hitObj to the gameobject of the raycast hit

Button handling complete

@RabbitKazma please document the ButtonHandler.cs changes (code changes on fade transition) here

[RotX18]

End scene now contains a text field for completion time

The scene now show the player's completion time

Code + description

EndSceneTimer.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using TMPro;

public class EndSceneTimer : MonoBehaviour
{
    public TextMeshProUGUI txtTimer;

    private void Start() {
        txtTimer.text = $"Completed in {LessThanTen(PlayerPrefs.GetFloat("minutes"))}min {LessThanTen(Mathf.Round(PlayerPrefs.GetFloat("seconds")))}s";
        PlayerPrefs.DeleteAll();
    }

    private string LessThanTen(float f) {
        if(f < 10) {
            return $"0{f}";
        }
        else {
            return f.ToString();
        }
    }
}

Description: Script makes use of PlayerPrefs to keep track of the player's completion time

• Start():
  • Sets the timer text to contain the player's completion time using PlayerPrefs.GetFloat("minutes") and PlayerPrefs.GetFloat("seconds")
  • Deletes the player completion time from PlayerPrefs
• LessThanTen(float f):
  • Appends a "0" to the f and returns as a string if f is less than 10

    private void FixedUpdate()
    {
        if (_doRaycast)
        {
            //casting from the main camera to the point on screen where the mouse is
            _pointerRay = new Ray(pointerOrigin.transform.position, pointerOrigin.transform.forward);

            if (Physics.Raycast(_pointerRay, out _hit))
            {
                //if the point where the player click contains a gameobject
                _hitObj = _hit.transform.gameObject;
            }
        }
    }

}

Description:

• Added:
  • 1 second timer before loading the next scene
  • timer increases each frame and is checked if it is more than 1 second before loading next scene
  • this timer is done so that there is leeway for the fade animation to play

Thanks @RabbitKazma, will close issue now
