[RotX18]

Objective: Add a timer to the game to add light pressure to the player

• [x] Timer should be easily visible
• [x] Timer should display in this format at all times (mm:ss)
• [x] End screen should show the completion time

Completed Timer

Timer works by counting the seconds using Time.deltaTime and incrementing the minutes by 1 every time the seconds value passes 59. and updating the float in PlayerPrefs

Code + Description

Timer.cs

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

public class Timer : MonoBehaviour
{
    #region PUBLIC VARS
    public TextMeshProUGUI txtTimer;
    #endregion

    #region PRIVATE VARS
    private float _minutes = 0;
    private float _seconds = 0;
    #endregion

    private void Update() {
        _seconds += Time.deltaTime;

        //updating the counter every minute
        if(_seconds > 59){
            _seconds = 0;
            _minutes += 1;
        }

        //updating the timer text in the scene
        txtTimer.text = $"{LessThanTen(_minutes)}:{LessThanTen(Mathf.Round(_seconds))}";

        //saving the current value into PlayerPrefs
        PlayerPrefs.SetFloat("minutes", _minutes);
        PlayerPrefs.SetFloat("seconds", _seconds);
    }

    private string LessThanTen(float f){ 
        //appending a "0" in front if f is less than 10
         if(f < 10){
            return $"0{f}";
        }
        else{
            return f.ToString();
        }
    }
}

Description: This script is responsible for setting the timer text in the game scene.

• Update():
  • Counts the seconds by adding Time.deltaTime to _seconds
  • Increments _minutes by 1 and resets _seconds to 0 for every minute that passes
  • Updating the txtTimer text to the current time
  • Saving the minutes and seconds to player prefs
• LessThanTen(float f):
  • Returns a string with the concatenated value of "0" and the f value if f is less than 10
  • Returns a f as a string if f is greater than 10

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: This script is found in the end game screen and is used to update the completion time script andd reset the values in PlayerPrefs.

• Start():
  • Sets the timer text to the values found in PlayerPrefs
  • Deletes the values after as the values will no longer be used in the next play through
• LessThanTen:
  • SAME AS THAT FOUND IN Timer.cs

Timer works and feature is implemented, issue will be closed
