Question

I need to get the variable score from my other class and set it as a UserPrefs key. it doesnt seem to be setting as i have a GUI label ingame which shos "None" if there is no UserPrefs key "Highscore".
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System.Threading;
public class Player : MonoBehaviour {
public Vector2 jumpForce = new Vector2(0, 300);
private Rigidbody2D rb2d;
Generator SwagScript;
GameObject generator;
// Use this for initialization
void Start () {
rb2d = gameObject.GetComponent<Rigidbody2D>();
generator = GameObject.FindGameObjectWithTag("Generator");
SwagScript = generator.GetComponent<Generator>();
}
// Update is called once per frame
void Update () {
if (Input.GetKeyUp("space"))
{
rb2d.velocity = Vector2.zero;
rb2d.AddForce(jumpForce);
}
Vector2 screenPosition = Camera.main.WorldToScreenPoint(transform.position);
if (screenPosition.y > Screen.height || screenPosition.y < 0)
{
Die();
}
}
void OnCollisionEnter2D(Collision2D other)
{
Die();
}
void Die()
{
if (PlayerPrefs.HasKey("HighScore"))
{
if (PlayerPrefs.GetInt("Highscore") < SwagScript.score)
{
PlayerPrefs.SetInt("HighScore", SwagScript.score);
}
else
{
PlayerPrefs.SetInt("HighScore", SwagScript.score);
}
}
Application.LoadLevel(Application.loadedLevel);
}
}

Answer 1

Unless you're creating the Highscore playerpref somewhere else, the Die() method won't never create it, since the if (PlayerPrefs.HasKey("HighScore")) will always return false.
Just remove that if.
