在特定范围内检测到玩家时，为什么炮塔不旋转？

Question

这是脚本我还将它附加到聚光灯上，当玩家在航点之间移动时，聚光灯会旋转并点亮玩家。

但是当我将剧本附加到炮塔时，我的炮塔旋转180度然后停止并且永远不会继续旋转跟踪玩家。

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

public class RotateSpotlight : MonoBehaviour
{
    public GameObject target;
    public float smooth = 1f;
    public float rangeSqr;
    public float rotationSpeed;
    Quaternion originalRotation;

    private void Start()
    {
        originalRotation = transform.localRotation;
    }

    private void Update()
    {
        if (target.transform.position.x < transform.position.x + rangeSqr)
        {
            var targetRotation = Quaternion.LookRotation(target.transform.position - transform.position);
            var str = Mathf.Min(rotationSpeed * Time.deltaTime, 1);
            transform.rotation = Quaternion.Lerp(transform.rotation, targetRotation, str);
        }
        else
        {
            var str = Mathf.Min(rotationSpeed * Time.deltaTime, 1);
            transform.rotation = Quaternion.Lerp(transform.rotation, originalRotation, str);
        }
    }
}

Answer 1

使用VectorX.Distance（）比使用pos x和pos y更好，更敏感。

我很确定你的问题来自于Quaternion.LookRotation，这个功能并没有给你你所期望的价值。

我个人用它进行角度计算：

    Vector3 a = targetPos - _transform.position;
    Vector3 b = Vector3.forward;
    float angle = Vector3.Angle(a, b);
    float finalAngle = (Vector3.Cross(a, b).y > 0 ? -angle : angle);

您可以查看“complet”代码

private void Update()
{
    //check range
    if (Vector3.Distance(targetPos, turretPos) < maxRange)
        AutoAttack(targetPos);
}
public override void AutoAttack(Vector3 targetPos)
{
    Vector3 a = targetPos - _transform.position;
    Vector3 b = Vector3.forward;
    float angle = Vector3.Angle(a, b);
    Rotation(Vector3.Cross(a, b).y > 0 ? -angle : angle);

    //this condition is to to fire only when the turret is currently looking at target
    if (Mathf.Abs(Mathf.DeltaAngle(_transform.eulerAngles.y, (Vector3.Cross(a, b).y > 0 ? -angle : angle))) < minAngleToFire)
        Attacking();
}
//call to rotate the in y axis
public void RotationY(float angle)
{
    _transform.rotation = Quaternion.Lerp(_transform.rotation, Quaternion.Euler(0, angle, 0), Time.deltaTime * rotationSpeed);
}
