c# - 转换位置时出现Unity3d错​​误

我的错误是



码:

using UnityEngine;
using System.Collections;

public class ResetBadPos : MonoBehaviour {
    Random r = new Random();
    int rInt = r.Next(0, 100); //for ints
    int range = 100;
    // Use this for initialization
    public int points = 0;

    void Start () {
    }

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

    void OnCollisionEnter2D(Collision2D col) {
        if (col.gameObject.name == "Bottom Boards") {
            points += 1;
            transform.position = new Vector3(r, -30, 0);
            Score.score += points;
        }
    }
}

编辑后我现在剩下的错误是

using UnityEngine;
using System.Collections;

public class ResetBadPos : MonoBehaviour {
    Random r = new Random();
    int rInt = r.Next(0, 100); //for ints
    int range = 100;
    // Use this for initialization
    public int points = 0;
    void Start () {
        r = new Random ();
    }

    // Update is called once per frame
    void Update () {
    }
        void OnCollisionEnter2D(Collision2D col) {

        if (col.gameObject.name == "Bottom Boards") {
            points += 1;
            transform.position = new Vector3(rInt, -30, 0);
            Score.score += points;
        }
    }
}

最新的代码和错误是现在
错误CS0236:字段初始化程序无法引用非静态字段，方法或属性'KillBad.r'(CS0236)(Assembly-CSharp)

using UnityEngine;
using System.Collections;

public class KillBad : MonoBehaviour {
    Random r;
    int rInt = r.Next(-50, 50); //for ints
    int range = 100;
    // Use this for initialization
    public int points = 0;
    void Start () {
        r = new Random ();
    }

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

    }
        void OnCollisionEnter2D(Collision2D col) {

        if (col.gameObject.name == "Bottom Boards") {
            points += 1;
            transform.position = new Vector3(rInt, -30, 0);
            Score.score += points;
        }
    }
}

谢谢大家，但现在我又遇到了另一个错误
错误CS1061:“UnityEngine.Random”不包含“Next”的定义，并且找不到扩展方法“Next”，该扩展方法接受“UnityEngine.Random”类型的第一个参数(您是否缺少using指令或程序集引用？ )(CS1061)(程序集-CSharp)

使用UnityEngine;
使用System.Collections;

public class KillBad : MonoBehaviour {
    Random r;
    int rInt;

    int range = 100;
    // Use this for initialization
    public int points = 0;
    void Start () {
        r = new Random ();
        rInt = r.Next(-50, 50);
    }

最佳答案

关于您的最新更新:目前，您的代码正在使用UnityEngine.Random class。但是，这个没有Next(int, int)函数。似乎您想使用确实具有Next-function的.net类System.Random。

您的解决方案将是:

using UnityEngine;
using System.Collections;

public class KillBad : MonoBehaviour {
    System.Random r;
    int rInt;

    int range = 100;
    // Use this for initialization
    public int points = 0;
    void Start () {
        r = new System.Random ();
        rInt = r.Next(-50, 50);
}
