我检查了 Youtube、Google 和以前的答案，但无法让我的游戏向鼠标射击。玩家旋转跟随鼠标，当他射击时它要么不准确，要么有时朝另一个方向射击。我真的不想发送大量代码，但我觉得我已经混合了来自不同教程的代码，尽管我有点组织它，但你可能最好看看它，非常抱歉，提前感谢

public class PlayerController : MonoBehaviour

    public int playerId = 0;
    public bool useController;

    public float Curserspeed = 5f;
    public Animator animator;

    }

    // Update is called once per frame
    void Update()
    {
        ProcessInputs();
        AimAndShoot();
        Animate();
        Move();

        Vector2 direction = Camera.main.ScreenToWorldPoint(Input.mousePosition) - transform.position;

                bullet.GetComponent<Rigidbody2D>().velocity = shootingDirection * 3.0f;
                bullet.transform.Rotate(0.0f, 0.0f, Mathf.Atan2(shootingDirection.y, shootingDirection.x) * Mathf.Rad2Deg);
                Destroy(bullet, 3.0f);
            }
int main()

    return 0;

如果您的玩家正在看鼠标，而您正试图在那里射击，这似乎有点复杂......

实例化子弹后，您只需要做两件事：立即旋转它，使其面向与玩家相同的方向。（这可以通过 transform.rotation= playerobject.rotation 来完成）施加向前的力。（由于对象面向玩家所面向的位置，因此当您“发射”弹丸时瞄准，您无需瞄准，只需将其发送到其前向轨迹即可）

transform.forward将在这里工作。
