C# 如何将光线投射与鼠标定位与等轴测相机统一对齐？

当鼠标未居中时，我很难想出如何弥补鼠标位置的偏移。统一的摄影机具有角度（30、45、0）并且是正交的。有关示例，请参见图像

我曾考虑在光线投射位置渲染十字线，但这仍然会使瞄准变得棘手

线渲染器的光线投射代码：

void Shoot ()
 {
     timer = 0f;

     gunAudio.Play ();

     gunLight.enabled = true;

     gunParticles.Stop ();
     gunParticles.Play ();

     gunLine.enabled = true;
     gunLine.SetPosition (0, transform.position);

     shootRay.origin = transform.position;
     shootRay.direction = transform.forward;

     if(Physics.Raycast (shootRay, out shootHit, range, shootableMask))
     {
         EnemyHealth enemyHealth = shootHit.collider.GetComponent<EnemyHealth>();

         if(enemyHealth != null)
         {
             enemyHealth.TakeDamage (damagePerShot, shootHit.point);
         }
         gunLine.SetPosition (1, shootHit.point);
     }
     else
     {
         gunLine.SetPosition (1, shootRay.origin + shootRay.direction * range);
     }
 }

void Turning()
 {
     Ray camRay = Camera.main.ScreenPointToRay(Input.mousePosition);

     RaycastHit floorHit;

     if (Physics.Raycast(camRay, out floorHit, camRayLength, floorMask))
     {
         Vector3 playerToMouse = new Vector3(floorHit.point.x, transform.position.y, floorHit.point.z);
         transform.LookAt(playerToMouse);
     }
 }

对于LineRenderer/Shot raycast，您没有检查是否只击中地板。所以在

else

块中

gunLine.SetPosition (1, shootRay.origin + shootRay.direction * range);

它将光线在给定方向上延续到“永恒”（或

范围

）。 您还应该在此处将地板添加到

floorMask

，这样光线也会照射到地板上

或者您可以使用以下方式组合图层值

 if(Physics.Raycast (shootRay, out shootHit, range, shootableMask | floorMask))
