Send a raycast between two objects that aren't facing each other - UnityScript

Hi there!

In my game, I've a ship with a 360º firing angle, and that means that a target can behind it and still be able to fire. However, I need to check the exact impacting point on the "Shield" trigger (if it has shields up), or the Ship collider itself.

So, that means I can't use transform.forward to shoot the raycast, so I need to find a way to discover the orientation between those two, so I can discover the "phaser" impact point...

Currently I've this:

 function CheckPhaserImpact (phaser_point : GameObject) : Vector3 {
     //set mask
     var hit : RaycastHit;
     var layerMask : int = 1 << 10; //layer 10 is the Player layer
     layerMask = ~layerMask;
     
     
     Physics.Raycast(phaser_point.transform.position, (phaser_point.transform.position - target.position).normalized, hit, Mathf.Infinity, layerMask);
     
     return hit.point;
 
 }

In the meanwhile, I'll keep searching for a solution...
