Raycast does not go in the right direction,Raycast not pointing in the correct direction

Hello, i wrote some code that is supposed to emit a raycast from the gameobject shoulder and goes through the gameobject hand. this is to give the direction that the mouse is so if my charecter picks up an item they could used that item in that direction, ie gun shoots in that direction. currently i only have it drawing the cast to debug it because the cast emits from the correct position but does not go through the hand. ive tried multiple iterations of this code based on the answers of previous question but it doesn't seem to work. the game is a 2.5D side scroller.

     pos.x = transform.position.x;
     pos.y = transform.position.y -1.4f;
     pos1.x = shoulder.transform.position.x;
     pos1.y = shoulder.transform.position.y;
     pos1.z = 15f;
     pos.z =0f;
     RaycastHit info;
     Debug.DrawRay(pos1, pos, Color.yellow);

ive tried linecast as well.the code is on the hand gameobject, it also does strange things when i move the charter from the orgin , like flip directions and only rotates halfway and doesn't emit the raycast in the opposite direction.,Hello, i wrote some code that is supposed to emit a raycast from the gameobject shoulder and goes through the gameobject hand. this is to give the direction that the mouse is so if my charecter picks up an item they could used that item in that direction, ie gun shoots in that direction. currently i only have it drawing the cast to debug it because the cast emits from the correct position but does not go through the hand. ive tried multiple iterations of this code based on the answers of previous question but it doesn't seem to work. the game is a 2.5D side scroller.
