VR speedrun timer

Question

I am working on a VR speedrun game and I need a timer. The timer doesn't need to be showed in the screen for the player, just on the map I made. It needs to start when the player (VR) passes a specific point and end when it reaches a different point. If anyone has an idea of how to make this work I would really appreciate it.

Answer 1

On the start line you could have an empty gameobject with a trigger collider on it, and in the OnTriggerEnter event you could start a Coroutine that keeps track of the time, and on the finish line you'd have another trigger collider that sets a flag and stops the timer.

Something along the lines of this should work:

using UnityEngine;
using System;

public class Player : MonoBehaviour {

    private bool _isTimerStarted = false;
    private float _timeElapsed = 0;
    
    private void OnTriggerEnter(Collider other) {
        if (other.gameObject.name.Equals("Start Line")) {
            _isTimerStarted = true;
            StartCoroutine(StartTimer());
        } else if (other.gameObject.name.Equals("Finish Line") {
            _isTimerStarted = false;
        }
    }

    IEnumerator StartTimer() {
        while (_isTimerStarted) {
            _elapsedTime += Time.deltaTime;
            yield return null;
        }
        yield break;
    }
}

For this to work just make sure your player has a RigidBody attached or else no collision will be detected :)
