Question

已解决 - 似乎我试图引用一个未通过引用传递的结构（vector2）。因此代码是变量/列表没有相互反映。

谢谢大家。

这是我正在使用的代码。我希望能够更改List引用的变量，并使列表反映更新的变量，而无需搜索列表并每次更新它。这将使我更容易更新我的buff，而不是。

这可能吗？

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
public class Buff : MonoBehaviour{


    // (Buff Amount, Timer)
    Vector2 thrust = new Vector2(1,0);
    Vector2 mass = new Vector2(1,0);
    Vector2 shield = new Vector2(1,0);
    Vector2 armor = new Vector2(1,0);
    Vector2 structure = new Vector2(1,0);
    Vector2 regen = new Vector2(1,0);
    Vector2 explosionRadius = new Vector2(1,0);
    Vector2 damage = new Vector2(1,0);
    Vector2 disable = new Vector2(0,0);

    List<Vector2> buffs = new List<Vector2>();

    // Use this for initialization
    void Start () {
        buffs.Add(thrust);
        buffs.Add(mass);
        buffs.Add(shield);
        buffs.Add(armor);
        buffs.Add(structure);
        buffs.Add(regen);
        buffs.Add(explosionRadius);
        buffs.Add(damage);
        buffs.Add(disable);
    }

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

        // Makes Regen variable change.
        regen[0] = 5;

        // Can I make it affect what is in the List of Vector 2's?
        foreach (Vector2 buff in buffs)
        {
            if (buff.magnitude > 1)
                UpdateBuff(buff);
        }
    }

    // Therefore this will be called. Then the variable outside can also be updated?
    void UpdateBuff(Vector2 inBuff)
    {
        Debug.Log("Updating Buff: " + inBuff.ToString());
        if ((inBuff[1] -= Time.deltaTime) <= 0)
        {
            inBuff[0] = 1;
            inBuff[1] = 0;
        }
    }

Answer 1

“Foreach”变量是只读的，这意味着你无法通过它们参考

Answer 2

修复了使用自定义类的问题。

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
public class Buff : MonoBehaviour{


    // (Buff Amount, Timer)
    public BuffInfo thrust = new BuffInfo(1,0);
    public BuffInfo mass = new BuffInfo(1,0);
    public BuffInfo shield = new BuffInfo(1,0);
    public BuffInfo armor = new BuffInfo(1,0);
    public BuffInfo structure = new BuffInfo(1,0);
    public BuffInfo regen = new BuffInfo(1,0);
    public BuffInfo explosionRadius = new BuffInfo(1,0);
    public BuffInfo damage = new BuffInfo(1,0);
    public BuffInfo disable = new BuffInfo(0,0);

    public List<BuffInfo> buffs = new List<BuffInfo>();

    float deltaUpdates = 0;
    // Use this for initialization
    void Start () {
        buffs.Add(thrust);
        buffs.Add(mass);
        buffs.Add(shield);
        buffs.Add(armor);
        buffs.Add(structure);
        buffs.Add(regen);
        buffs.Add(explosionRadius);
        buffs.Add(damage);
        buffs.Add(disable);
        regen.power = 5;
    }

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

        // Makes Regen variable change.


        if ((deltaUpdates += Time.deltaTime) < 1)
            return;

        // Can I make it affect what is in the List of Vector 2's?
        foreach (BuffInfo buff in buffs)
        {
            if (buff.magnitude() > 1)
                UpdateBuff(buff);
        }

        deltaUpdates = 0;
    }

    // Therefore this will be called. Then the variable outside can also be updated?
    void UpdateBuff(BuffInfo inBuff)
    {
        Debug.Log("Updating Buff: " + inBuff.ToString());
        if ((inBuff.power -= deltaUpdates) <= 0)
        {
            inBuff.power = 1;
            inBuff.time = 0;
        }
    }
}

列表中的对象可以引用变量吗？
