How do I save my Highest time using playerprefs?
Hi,
I'm currently working on a endless runner game and im struggling with my high score. I have a timer script that works just fine, but I want to able to save the highest score using playerprefs. Does anyone have a clue on how I can do this?
Here's my current timer script:
using UnityEngine;
using System.Collections;
using UnityEngine.UI;
public class Timer : MonoBehaviour {
public Text timer;
public float highscore = 0;
public float seconds = 00;
public float miliseconds = 00;
static public float minutes = 00;
public Canvas canvas;
void FixedUpdate(){
if (miliseconds >= 60) {
seconds++;
miliseconds = 00;
}
if (seconds >=60) {
minutes++;
seconds = 00;
}
if (GameOver.gameover == false) {
miliseconds += Time.deltaTime * 60;
}
timer.text = minutes.ToString ("00") + ":" + seconds.ToString ("00") + ":" + miliseconds.ToString ("00");
}
}
Try searching for the term "PlayerPrefs" using the search box above, there are plenty of examples already in these pages.
Hi Joey,
You can save your highscore time just by doing :
PlayerPrefs.SetInt("Minutes", minutes);
PlayerPrefs.SetInt("Seconds", seconds);
PlayerPrefs.SetInt("Miliseconds", miliseconds);
after you've done that, and you want to check if your new score is bigger than your saved score do:
int highscoreMins = PlayerPrefs.GetInt("Minutes");
int highscoreSec = PlayerPrefs.GetInt("Seconds");
int highscoreMilisec = PlayerPrefs.GetInt("Miliseconds");
//compare those with your old ones
if(minutes > highscoreMins){
//new highscore
SetNewHighscore();
} else if(minutes == highscoreMins){
if(seconds > highscoreMins){
//new highscore
SetNewHighscore();
}
if(seconds == highscoreSec){
if(miliseconds > highscoreMilisec){
//new highscore
SetNewHighscore();
} else {
//do nothing
}
}
}
void SetNewHighscore(){
PlayerPrefs.SetInt("Minutes", minutes);
PlayerPrefs.SetInt("Seconds", seconds);
PlayerPrefs.SetInt("Miliseconds", miliseconds);
}
hope it helped a bit more info: https://docs.unity3d.com/ScriptReference/PlayerPrefs.html
I also recommend to use const strings to declare your saveData names like:
const string $$anonymous$$utesPlayerPrefs = "$$anonymous$$inutes";
const string secondsPlayerPrefs = "Seconds";
const string milisecondsPlayerPrefs = "$$anonymous$$iliseconds";
and then when you try to get or set your prefs use:
PlayerPrefs.SetInt($$anonymous$$utesPlayerPrefs , $$anonymous$$utes); // set $$anonymous$$utes
int highscore$$anonymous$$inutes = PlayerPrefs.Getint($$anonymous$$utesPlayerPrefs); // get $$anonymous$$utes
PlayerPrefs.SetInt(secondsPlayerPrefs , seconds); // set seconds
int highscoreSeconds = PlayerPrefs.Getint(secondsPlayerPrefs); // get seconds
PlayerPrefs.SetInt(milisecondsPlayerPrefs , miliseconds); // set miliseconds
int highscore$$anonymous$$iliseconds = PlayerPrefs.Getint(milisecondsPlayerPrefs); // get miliseconds
to prevent misspelling, and errors.
You save a playerpref by doing PlayerPrefs.SetInt("$$anonymous$$inutes", $$anonymous$$utes);
The changes you make using the Set functions will not persist unless you subsequently call PlayerPrefs.Save()
It's more common to convert to a single unit, like only seconds. $$anonymous$$akes the code faster and less error-prone. For example, there's a small bug where you compare seconds to $$anonymous$$utes. Not completely on you, since the OP is already using the not-so-good seconds+$$anonymous$$utes way.
The conversion to $$anonymous$$utes/seconds/etc is generally then done only when displaying to the human.
