RayCast2D direction is always showing origin point(0,0,0) on game and ignores direction Vector2D.(Unity 2017.4.7.f1)

Im working on a game which includes a soldier defending a barracks and he carries a gun. He is rotating arm on z-axis with joystick and other stuffs (muzzle flash, line renderer,rifles, etc.). And when it came to line RayCast2D some worked. RayCast2D origin is working but direction vector is not working. I attain both value and direction from the center point. I set the direction point at 1 unit from the center point on the sceen.Direction point is not working on the script. It is always showing the same place which is origin point on the Scene.
