如何根据鼠标指针的位置从屏幕中心向特定方向启动实例化对象？

Question

我正在创建一个简单的游戏，你被锁在屏幕中央，必须在物体向你移动时拍摄它们。我目前面临的问题是，我无法向鼠标光标的方向发射子弹。目前，我的代码是这样的

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

public class Bullet : MonoBehaviour {

    PlayerScript playerScript;
    public float xVel;
    public float yVel;
    public float direction;

    private void Awake()
    {
        playerScript = FindObjectOfType<PlayerScript>();
        //playerScript.AngleDeg is the direction the player is facing (based on mouse cursor)
        transform.rotation = Quaternion.Euler(0, 0, playerScript.AngleDeg);

        direction = transform.rotation.z;

        //from the unit circle (x = cos(theta), y = sin(theta)
        xVel = Mathf.Cos(direction *  Mathf.PI);
        yVel = Mathf.Sin(direction *  Mathf.PI);

    }

    void Update () {
        transform.position += new Vector3(xVel,yVel,0);
    }
}

目前，当我运行代码时，子弹射出的角度是正确的，当玩家侧向时，子弹射出的角度是正确的，但当玩家垂直定向时，子弹射出的角度是完全45度。

将其作为组件附加到实例化的bullet对象，它应该可以工作。

    Transform playerTransform;
    float bulletSpeed;
    Vector3 directionToShoot

    void Start()
    {
    playerTransform = FindObjectOfType<PlayerScript>().gameObject.transform;
    bulletSpeed = 3f;
    //Direction for shooting
    directionToShoot = playerTransform.forward - Camera.main.ScreenToWorldPoint(Input.mousePosition);
    }

    void Update()
    {
    //shoot
    transform.Translate(directionToShoot * bulletSpeed * Time.deltaTime);
    }
