PlayerPrefs, First time applying and need help.
Hello community.
I want to save lives after the level is restarted by pressing a button, I've applied PlayerPrefs but it do nothing on the practice.
Here I'll copy my scripts.
using UnityEngine;
using System.Collections;
public class VidaScript : MonoBehaviour {
//Interfaz Grafica Vida
public int vida = 2;
public GUIText LivesText;
//Prueba
public static string Vidas;
void Start () {
UpdateVida ();
}
public void Subtract (int newValueVida)
{
vida -= newValueVida;
UpdateVida ();
PlayerPrefs.SetInt (Vidas, newValueVida);
}
void UpdateVida ()
{
LivesText.text = "Lives: " + vida;
}
}
And the other script.
using UnityEngine; using System.Collections;
/// Script despues de morir
public class GameOverScript : MonoBehaviour {
private VidaScript vidaScript;
private int lives;
void Start ()
{
GameObject vidaScriptObject = GameObject.FindGameObjectWithTag ("VidaScript");
if (vidaScriptObject != null) {
vidaScript = vidaScriptObject.GetComponent <VidaScript> ();
}
if (vidaScript == null) {
Debug.Log ("No se puede encontrar VidaScript");
}
}
void OnGUI()
{
const int anchoBoton = 140;
const int altoBoton = 60;
if (
GUI.Button(
new Rect(
Screen.width / 2 - (anchoBoton / 2),
(1 * Screen.height / 3) - (altoBoton / 2),
anchoBoton,
altoBoton
),
"Restart level"
)
)
{
// Reiniciamos el nivel y no destruimos.
Application.LoadLevel(Application.loadedLevel);
PlayerPrefs.GetInt(VidaScript.Vidas);
}
if (
GUI.Button(
new Rect(
Screen.width / 2 - (anchoBoton / 2),
(2 * Screen.height / 3) - (altoBoton / 2),
anchoBoton,
altoBoton
),
"Back to MainScreen"
)
)
{
// Vamos a Menu
Application.LoadLevel("StartScene");
}
}
}
If somebody can explain to me, why it don't work and how it works, I'll really appreciate it.
Thanks a lot for your help.
I've done it in a diferrent way. And it works perfect! Thanks for the help, Steel_Arm you guide me in the way.
Here's my code.
using UnityEngine;
using System.Collections;
public class VidaScript : MonoBehaviour {
//Interfaz Grafica Vida
public int vida = 0;
private static int vidasIniciales = 2;
private static int vidasActuales;
public GUIText LivesText;
//Prueba
static VidaScript ()
{
vidasActuales = PlayerPrefs.GetInt("lives", vidasIniciales);
}
public static int VidasActuales {
get { return vidasActuales; }
set {
vidasActuales = Mathf.Max (0, value); // Para que no de negativo.
PlayerPrefs.SetInt ("lives", vidasActuales);
}
}
void Start ()
{
vidasActuales = PlayerPrefs.GetInt("lives", vidasIniciales);
UpdateVida ();
}
public void Subtract (int newValueVida)
{
vida -= newValueVida;
UpdateVida ();
}
void UpdateVida ()
{
LivesText.text = "Lives: " + vidasActuales.ToString ();
}
public void drecrementoVidas ()
{
vidasActuales--;
PlayerPrefs.SetInt("lives", vidasActuales);
}
public void incrementoVidas ()
{
vidasActuales++;
PlayerPrefs.SetInt("lives", vidasActuales);
}
public void zeroVidas()
{
if (VidaScript.vidasActuales > 0)
Application.LoadLevel("StartScene");
}
}
Change this:
PlayerPrefs.SetInt (Vidas, newValueVida);
to be this:
PlayerPrefs.SetInt (Vidas, vida);
And this:
PlayerPrefs.GetInt(VidaScript.Vidas);
should instead be this:
vidaScript.vida = PlayerPrefs.GetInt(VidaScript.Vidas);
That should do it.
Thanks for helping me, but It doesn't work.
I've this too in my script of health. $$anonymous$$aybe it cause some error and restart the value?
//Llamamos al VidaScript y a un int para newValueVida
private VidaScript vidaScript;
private int lives = 1;
/// Es jugador o enemigo?
public bool esEnemigo = true;
void Start ()
{
GameObject vidaScriptObject = GameObject.FindGameObjectWithTag ("VidaScript");
if (vidaScriptObject != null) {
vidaScript = vidaScriptObject.GetComponent <VidaScript>();
}
if (vidaScript == null) {
Debug.Log ("No se puede encontrar VidaScript");
}
}
void OnTriggerEnter2D(Collider2D collider)
{
//Es un disparo?
Disparar disparo = collider.gameObject.GetComponent<Disparar>();
if (disparo != null)
{
// Revisamos si es enemigo o compañero
if (disparo.esDisparoEnemigo != esEnemigo)
{
ps -= disparo.daño;
// Destruimos el disparo
// No colocar solo Destroy()
//sino eli$$anonymous$$ara el Script
Destroy(disparo.gameObject);
if (ps <= 0)
{
// $$anonymous$$uerto + EfectoEspecial de particulas
vidaScript.Subtract(lives);
EfectosEspecialesScript.Instancia.Explosion(transform.position);
EfectosDeSonido.Instancia.ReproducirSonidoExplosion();
Destroy(gameObject);
Well, I don't see a place where you initialize the value of "vida". When you start a new game, you need to set the value of "vida" to something. Possibly, you could do this in vidaScript:
void Start() {
if (PlayerPrefs.Has$$anonymous$$ey(Vidas) == true) {
vida = PlayerPrefs.GetInt(Vidas);
}
else {
vida = 3; // set as whatever you want for initial lives.
}
}
And make sure you don't make VidaScript persistent, so it reloads with a level reload. With that, you change this:
// Reiniciamos el nivel y no destruimos.
Application.LoadLevel(Application.loadedLevel);
PlayerPrefs.GetInt(VidaScript.Vidas);
To be just this:
// Reiniciamos el nivel y no destruimos.
Application.LoadLevel(Application.loadedLevel);
If I remember correctly, I think Application.LoadLevel() doesn't return anyways, so that line about PlayerPrefs.GetInt() is never reached. But I could be wrong. Either way, this should work. I think.
