错误CS0029：无法将类型'int'隐式转换为'Score'

Question

I have searched for a while and can't find and answer hoping someone can help me!. What I am trying to do is save my Score and transfer it to a different scene. With this code I have here I get the error :

error CS0029: Cannt implicitly convert type 'int' To 'Score'

I am rather new to unity script as well.

Here are the two scripts I am using

Script 1 Score.cs

using UnityEngine;
using System.Collections;

public class Score : MonoBehaviour {

    static public int score = 0;
    static public int highScore = 0;

    static Score instance;

    static public void AddPoint() {
        if(instance.run.dead)
            return;

        score++;

        if(score > highScore) {
            highScore = score;
        }
    }
    Running run;

    void Start() {
        instance = this;
        GameObject player_go = GameObject.FindGameObjectWithTag("Player");
        if (player_go == null) {
            Debug.LogError("could not find an object with tag 'Player'.");
        }
        run = player_go.GetComponent<Running> ();
        score = 0;
    }

    void OnDestroy() {
        PlayerPrefs.SetInt ("score", score);
    }

    void Update () {
        guiText.text = "Score: " + score;
    }
}

and the second script to get it to the other scene

using UnityEngine;
using System.Collections;

public class GetScore : MonoBehaviour {

    Score score;

    // Use this for initialization
    void Start () {
        score = PlayerPrefs.GetInt ("score");

    }

    // Update is called once per frame
    void Update () {
        guiText.text = "Score: " + score;

    }
}

Really appreciate any help!

Answer 1

score = PlayerPrefs.GetInt ("score");

The error is caused by above line. PlayerPrefs.GetInt as it name states will return an integer. And now see how you declare the score variable:

Score score;

This causes the variable score have a type Score class, not int .

I suppose you want to set the variable score in Score class. Since you declare the variable score as static public , that makes things easy. You don't have to create an instance of Score , just use the class name Score (with capital S) instead:

Score.score = PlayerPrefs.GetInt("score");

Answer 2

PLayerPrefs.GetInt will return an int but you put a Score class clone to assign the returning value of PLayerPrefs.GetInt to it , int cant become Score so if you want to access the score class variable you should do this

void Start () {
    score=score.GetComponent<Score>();
    score.score = PlayerPrefs.GetInt ("score");

}

because your score varaible is static you can use this too

 void Start () {

    Score.score = PlayerPrefs.GetInt ("score");

}
