Getting a Vector2 position depending on the rotation of an object

Hey Guys,

so I have a 2D game. I want my character to test, whether an object is too close to it by sending Raycasts to the mouse Position (the direction he will be going). If so then it should not move. My character is a cube with a small cube ontop to illustrate the direction

Now my character can also hang on these w$$anonymous$$te walls, i.g. change rotation. In my code I want to calculate the position from where the rays should fire (I have rays colliding with own collider disabled). So I need to calculate these positions (blue dots) relative to the objects rotation. How do I do that? My approach is to first calculate the spacing. I do that by dividing the "width" of the sprite (w$$anonymous$$ch I hardcoded as 0.5f) by the number of rays - 1. I want the last ray to always be on the end so I do not include it. Then I calculate the position as seen in the for-loop. And I do not know how to rewrite it like so, that the position defined by the hard coded values are not in world space, but local space. How do I do that? transform.TransformPoint does not seem to work as well as multiplying by transform.up.

Maybe someone has a suggestions. Here is the code:

     private bool ValidateMove()
     {
         Vector2 mousePosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
 
         bool $$anonymous$$tSomet$$anonymous$$ng = false;
 
         float spacing = 0.5f / rayCount;
         for (int i = 0; i < rayCount - 1; i++)
         {
             Vector2 position = new Vector2(transform.position.x - 0.25f + spacing * i, transform.position.y - 0.24f);
             RaycastHit2D $$anonymous$$t = Physics2D.Raycast(position, (mousePosition - position).normalized, maxWallDistance);
             if ($$anonymous$$t.collider != null)
             {
                 if ($$anonymous$$t.collider.gameObject.CompareTag("isEnvironment"))
                 {
                     $$anonymous$$tSomet$$anonymous$$ng = true;
                 }
             }
         }
         Vector2 positionLast = new Vector2(transform.localPosition.x + 0.25f, transform.position.y - 0.24f);
         RaycastHit2D $$anonymous$$tLast = Physics2D.Raycast(positionLast, (mousePosition - positionLast).normalized, maxWallDistance);
         if ($$anonymous$$tLast.collider != null)
         {
             if ($$anonymous$$tLast.collider.gameObject.CompareTag("isEnvironment"))
             {
                 $$anonymous$$tSomet$$anonymous$$ng = true;
             }
         }
         if ($$anonymous$$tSomet$$anonymous$$ng)
         {
             return false;
         }
         return true;
     }
