Question

我正在制作一个基本的篮球比赛，我有一个名为dunkComplete的公共布尔值，在球被扣篮后被激活，并被用于球脚本，我试图在游戏管理器脚本中引用这个布尔值但是由于某种原因，即使dunkComplete成为现实，它的游戏管理器对手也不会，游戏管理器脚本可供参考。

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

public class game_manager : MonoBehaviour {

    public GameObject Basket;

    private float x_value;
    private float y_value;

    public GameObject ball;
    private ball_script basketBallScript;
    private bool dunkCompleteOperation;

    // Use this for initialization
    void Start () {
        basketBallScript = ball.GetComponent<ball_script>();

        Vector2 randomVector = new Vector2(Random.Range(-9f, 9f), Random.Range(0f, 3f));

        Debug.Log(randomVector);

        Instantiate(Basket, randomVector, transform.rotation);

        Instantiate(ball, new Vector2(0, -3.5f), transform.rotation);
    }

    // Update is called once per frame
    void Update () {

        dunkCompleteOperation = basketBallScript.dunkComplete;

        if (dunkCompleteOperation == true)
        {
            Vector2 randomVector = new Vector2(Random.Range(-9f, 9f), Random.Range(0f, 3f));

            Instantiate(Basket, randomVector, transform.rotation);
        }
    }
}

任何帮助都会有很大的帮助。

Answer 1

你的basketBallScript没有引用你实例化的球对象的ball_script。您应该保留对您创建的GameObject的引用，然后分配basketBallScript。

试试这个：

public class game_manager : MonoBehaviour {

    public GameObject Basket;

    private float x_value;
    private float y_value;

    public GameObject ball;
    private ball_script basketBallScript;
    private bool dunkCompleteOperation;

    // Use this for initialization
    void Start () {

        Vector2 randomVector = new Vector2(Random.Range(-9f, 9f), Random.Range(0f, 3f));

        Debug.Log(randomVector);

        Instantiate(Basket, randomVector, transform.rotation);
        // Get the ref. to ballObj, which is instantiated. Then assign the script.
        GameObject ballObj = Instantiate(ball, new Vector2(0, -3.5f), 
        transform.rotation) as GameObject;
        basketBallScript = ballObj.GetComponent<ball_script>();
    }

    // Update is called once per frame
    void Update () {

        dunkCompleteOperation = basketBallScript.dunkComplete;

        if (dunkCompleteOperation == true)
        {
            Vector2 randomVector = new Vector2(Random.Range(-9f, 9f), Random.Range(0f, 3f));

            Instantiate(Basket, randomVector, transform.rotation);
        }
    }
}

另外，为了让您的代码在将来更容易关注其他代码，您可能需要查看general naming conventions。

引用非静态变量
