如何检测范围内的特定对象，在人工智能上？
如何检测范围内的特定对象，在人工智能上？

所以我正在从光谱中复制游戏“蛇坑”。你可以像你的玩家一样移动，还有多条人工智能控制的蛇。当蛇头就在你旁边的时候，我想弄清楚如何让它们移动到你的位置。下面是我想要将其实现到的代码。
public class SnakeController : MonoBehaviour {
public int maxSize;
public int currentSize;
public GameObject snakePrefab;
public Snake Head;
public Snake Tail;
public Vector2 nextPos;
public int NESW;
int Random;
float lineTimer;
int NESWTemp;
// Use this for initialization
void Start () {
InvokeRepeating("TimerInvoke", 0, .3f);
lineTimer = UnityEngine.Random.Range(0, 2.5f);
currentSize = 1;
}
// Update is called once per frame
void Update () {
lineTimer -= Time.deltaTime;
if (lineTimer <= 0)
{
ComChangeD();
lineTimer = UnityEngine.Random.Range(0, 2.5f);
}
}
void TimerInvoke()
{
Movement();
if(currentSize >= maxSize)
{
TailFunction();
}
else
{
currentSize++;
}
}
void Movement()
{
GameObject temp;
nextPos = Head.transform.position;
if(nextPos.y > 3.22)
{
NESW = 2;
}
else if (nextPos.y < -4.42)
{
NESW = 0;
}
else if (nextPos.x < -8.2)
{
NESW = 1;
}
else if (nextPos.x > 7.7)
{
NESW = 3;
}
switch (NESW)
{
case 0:
nextPos = new Vector2(nextPos.x, nextPos.y + 0.32f);
break;
case 1:
nextPos = new Vector2(nextPos.x + 0.32f, nextPos.y);
break;
case 2:
nextPos = new Vector2(nextPos.x, nextPos.y - 0.32f);
break;
case 3:
nextPos = new Vector2(nextPos.x - 0.32f, nextPos.y);
break;
}
temp = (GameObject)Instantiate(snakePrefab, nextPos, transform.rotation);
Head.SetNext(temp.GetComponent<Snake>());
Head = temp.GetComponent<Snake>();
return;
}
void ComChangeD()
{
NESWTemp = UnityEngine.Random.Range(0, 3);
if (NESW == 0)
{
switch (NESWTemp)
{
case 0:
NESW = 1;
break;
case 1:
NESW = 2;
break;
case 2:
NESW = 3;
break;
}
}
else if (NESW == 1)
{
switch (NESWTemp)
{
case 0:
NESW = 0;
break;
case 1:
NESW = 2;
break;
case 2:
NESW = 3;
break;
}
}
else if (NESW == 2)
{
switch (NESWTemp)
{
case 0:
NESW = 0;
break;
case 1:
NESW = 1;
break;
case 2:
NESW = 3;
break;
}
}
else if (NESW == 3)
{
switch (NESWTemp)
{
case 0:
NESW = 0;
break;
case 1:
NESW = 1;
break;
case 2:
NESW = 2;
break;
}
}

在蛇头下创建空游戏对象，并将其称为“DetectRange”或类似的东西。然后将它的宽度和高度设置为您希望您的蛇跟随玩家的范围的宽度和高度。因此，如果玩家进入这个范围，蛇将开始跟随。然后，您可以将player对象的标记设置为"Player“或类似的东西(在检查器的顶部)。然后将脚本附加到DetectRange中，然后在其中执行以下操作：
public GameObject playerObject; //Drag player gameobject in inspector
private float snakeSpeed = 1.0f;
void OnTriggerStay(Collider col)
{
if(col.gameObject.Tag == "Player") //Check if player entered collider
{
playerObject.transform.position = Vector3.MoveTowards(playerObject.transform.position, col.gameObject.position, snakeSpeed);
}
