Question by u2dpb · Aug 24, 2020 at 10:58 AM · 2d game2d-physics2d sprites2d rotation

Slow Sprite Rotation Toward Movement Direction - Top-Down 2D Game

I have a projectile I want the player to control. I want the sprite that is the projectile to slowly rotate toward the movement direction the player is holding down. I can get it to snap to the direction, but that's jarring. Many other answers have a target, but I'd like this to be freeform movement without a specific target. Just controlled with the directional inputs. Any ideas?

  private void Update()
      {
          horizontal = Input.GetAxisRaw("Horizontal");
          vertical = Input.GetAxisRaw("Vertical");
          move = new Vector2(horizontal, vertical);
          if (Input.GetKey(KeyCode.LeftShift))
          {
              playerControlling = true;
              if (move.x != 0 || move.y != 0)
              {
                  //rigidbody2d.rotation = Mathf.Atan2(move.y, move.x) * Mathf.Rad2Deg; //rotate on a dime but it's too much
              }
              else
              {
                  playerControlling = false;
              }
              rigidbody2d.AddForce(move);
          }
      }
