在本教程中，我被困在敌人的 2D AI 代码上

Question

我在看这个令人困惑的教程，讲的是如何制作一个跟随玩家对象的简单AI。当在视频中这样做时，它告诉我做这个尚未定义的"castPoint"变量。我知道。。。我知道这听起来很简单，但这个家伙的教程太慢了，这让我这个有阅读障碍的人很难集中注意力并很好地理解。我在C#方面也不是最好的，所以是的。所以请有人帮帮我！

这是代码，视频，如果我是@t:

我的代码：

//ignore this code!!!

//Enemy part tracking blablablaaaaa

public Transform Player;
[SerializeField]
float agroRange;

float moveSpeed;
private  Rigidbody2D rb2det;  
//End of ai part

void Start()
{
//ignore this code!!!
Enemtestone = GetComponent<Animator>();
//FirstTrig.SetActive(true);
Izintyloip = false;

Thecheckert = false;
//ignore this code!!!

}
// Update is called once per frame
void Update()
{
if (Izintyloip == true) { 
Enemtestone.SetInteger("Wakeup", 1);
Thecheckert = true;
}

}

bool CanSeePlayer(float distance)
{
bool val = false;
float castDist = distance;

Vector2 endPos = castPoint.position + Vector3.right * distance;

RaycastHit2D hit = Physics2D.Linecast(castPoint.position, endPos, 1 << LayerMask.NameToLayer("Action"));

您错过了7:49中他添加名为castPoint的转换的步骤。
