Line Casting: GameObject Face 射线的端点

Question

我正在尝试让敌方对象面向线投射的末端。当正确检测到时，我的代码会将射线锁定到播放器上。我的问题是我的敌人精灵是 Rigidbody2D 的孙子，我正在使用 eulerAngles 来改变精灵的方向。这是我的代码：

using UnityEngine;

public class PlayerDetection : MonoBehaviour
{
public Transform origin, end, player;
public float radarSpd;
public bool playerDetected;

public static bool playerIsDetected;

private int playerLayer = 1 << 8;
private Rigidbody2D enemyRb;
private Vector3 facePlayer;

private void Start()
{
    enemyRb = GetComponentInParent<Rigidbody2D>();
    playerIsDetected = false;
}

private void Update()
{
    PlayerDetector();
    if (playerDetected == false)
    {
        Radar();
    }
    else { PlayerIsDetected(); }

}

void PlayerDetector()
{
    Debug.DrawLine(origin.position, end.position, Color.red);
    playerDetected = Physics2D.Linecast(origin.position, end.position, playerLayer);
}

void Radar()
{
    end.RotateAround(origin.position, Vector3.forward, radarSpd * Time.deltaTime);
}

void PlayersPosition()
{
    facePlayer = player.position - enemyRb.transform.GetChild(0).GetChild(0).position;
    float enemyRot = Mathf.Atan2(facePlayer.y, facePlayer.x) * Mathf.Rad2Deg;
    enemyRb.transform.GetChild(0).GetChild(0).eulerAngles = new Vector3(0, 0, enemyRot);

}

void PlayerIsDetected()
{
    if(playerDetected == true)
    {
        playerIsDetected = true;
        end.position = player.position;
        PlayersPosition();
    }
}
}

我需要帮助的这段代码的主要焦点在这里：

void PlayersPosition()
{
facePlayer = player.position - enemyRb.transform.GetChild(0).GetChild(0).position;
float enemyRot = Mathf.Atan2(facePlayer.y, facePlayer.x) * Mathf.Rad2Deg;
enemyRb.transform.GetChild(0).GetChild(0).eulerAngles = new Vector3(0, 0, enemyRot);

}

当玩家在屏幕上移动时，敌人根本不面向玩家并且似乎根本没有旋转太多。

我试过应用 rotationSpeed 变量并将其乘以 enemyRot 乘以 Time.deltaTime 但也没有用。

 enemyRb.transform.GetChild(0).GetChild(0).eulerAngles = new Vector3(0, 0, enemyRot * rotSpd * Time.deltaTime);

我已经坚持了一个星期了，真的需要一些帮助来解决这个问题！那么如何使用 eulerAngles 实现我想要的旋转？

Answer 1

原来我做的数学题太多了。这是解决方案：

编辑：我的敌人面朝上。此代码适用于该规模。

void PlayersPosition()
{
    facePlayer = player.position - enemyRb.transform.GetChild(0).GetChild(0).position;
    enemyRb.transform.GetChild(0).GetChild(0).up = -facePlayer;
}
