无法在Unity C中跟踪对象的位置＃

Question

我有一个非常奇怪的问题，我几个小时都无法解决。我试图在两个物体彼此靠近时触发和发生事件。我过去从来没有遇到任何麻烦，但由于某种原因，这次我正在看的对象的位置似乎没有更新，而当我打印（）它返回原始的开始位置对象而不是它们当前的位置。

在游戏窗口和检查器中，我可以看到对象（代理）正在改变位置。但事件未被触发，因为代码认为对象处于其原始起始位置。

我的代码中有一些奇怪的自然语言功能，比如“a”类和“the”类，它们保存公共变量并存在于场景中。 Self类“my”继承自具有一个变量Self class“my”的Agent类。 Self类直接在游戏对象上。我将Agent与Self分开的唯一原因是玩家可以控制场景中的任何Self类，而无需拥有自己的Self类。

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

public class Brain : Agent {

    public List<Self> sight;
    public float time;

    void Start () {
        the = my.the;
        a = my.a;
    }

    void Update () {
        // set thinking interval
        if (time <= Time.deltaTime - 0.5) {
            time = Time.deltaTime;
            Think ();
        }

        // set a random destination based on current destination
        Vector2 randomVector = Vector2.one * Random.Range(-0.1f, 0.1f);
        my.destination += randomVector;
    }

    void Think() {

        print(FindObjectOfType<Agent>().transform.position); // a test that always returns the initial starting position rather than the current position (I don't know why)

        foreach (Self their in transform.parent.GetComponentsInChildren<Self>()) {

            if (their != my) { // don't perform this action on myself

                print (my.name + "'s position is... " + my.transform.position); // returning start position not current position
                print (their.name + "'s position is... " + their.transform.position); // returning start position not current position

                if (the.Distance (my.transform.position, their.transform.position) < my.vision && !sight.Contains (their)) {

                    Limb limb = (Limb)Instantiate (a.limb);
                    limb.transform.parent = my.transform;
                    limb.transform.localPosition = Vector2.zero;
                    limb.focus = their.gameObject;
                    sight.Add (their);

                }
            }
        }
    }

对于那些在彼此视觉距离内开始的物体，肢体在游戏开始时实例化，但这应该在整个游戏中间隔更新。

非常感谢任何帮助。以下是其他类的进一步参考。
