崩溃

[基森]

当我运行此代码并且foodobject不在搜索范围的搜索范围内时，我的单位崩溃"player".
的"player"应该搜索最接近的食物对象，如果没有食物对象，则应该选择一个随机位置并朝该位置移动。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class move : MonoBehaviour
{
public float scope = 10;
public float speed = 1;
Vector2 randomPos;
bool Notarget = true;
bool canChoose = true;
// Update is called once per frame
void Update()
{
FindClosestConsumable();
}

void FindClosestConsumable()
{
float distance = Mathf.Infinity;
consumable closestConsumeable = null;
        consumable[] AllConsumables = GameObject.FindObjectsOfType<consumable>();
        foreach(consumable currentConsumable in AllConsumables)
{
float distanceToFood = (currentConsumable.transform.position - this.transform.position).sqrMagnitude;
if(distanceToFood < distance)
{
distance = distanceToFood;
closestConsumeable = currentConsumable;
}
}
Debug.DrawLine(this.transform.position, closestConsumeable.transform.position);

if(Mathf.Sqrt(Mathf.Pow((this.transform.position.x - closestConsumeable.transform.position.x),2) + Mathf.Pow(this.transform.position.y-closestConsumeable.transform.position.y,2)) < scope)
{
Notarget = false;
this.transform.position = Vector2.MoveTowards(this.transform.position, closestConsumeable.transform.position, speed*Time.deltaTime);
}
else
{
Notarget = true;
while (Notarget)
{
if (canChoose)
{
float Height = Random.Range(-4.5f, 4.5f);
float Width = Random.Range(-7f, 7f);
randomPos = new Vector2(Width, Height);
canChoose = false;
                }


this.transform.position = Vector2.MoveTowards(this.transform.position, randomPos, speed * Time.deltaTime);
}

}
}
}

 

[羊皮]

1. 什么食物对象？
2. 什么探视镜？
3. 什么 播放器?
4. 说明您的代码在做什么，但不应这样做。
5. 错误出现在哪一行？

您是否尝试过调试？如果您编写了此内容，则应该知道它在做什么。这看起来像是找到最近敌人的编辑脚本...

邪恶代码

while (Notarget)
      {
          if (canChoose)
      {

什么时候退出循环，更是如此；为什么甚至需要循环？

Are you sure that closestConsumable is not null by the time you get to line 31 and/or 33?
