ArcBetweenPoints clockwise

[lucasbracher]

Hello! I'm trying to draw an ArcBetweenPoints clockwise, i.e., with the arc passing "over", not "under".

I tried it setting angle= and start_angle=, with no avail.

Any help is appreciated!

I am not sure if I understand your question correct, but does this help you:

class clockwiseArc(Scene):
   def construct(self):
      A0=ORIGIN #center
      radius=1
      start_angle=20*DEGREES
      angle = 130*DEGREES  
      end_angle=start_angle+angle
      start=np.array([cos(start_angle),sin(start_angle),0])*radius
      end=np.array([cos(end_angle),sin(end_angle),0])*radius
      arc_counterclockwise = ArcBetweenPoints(start=start,
                    end=end,
                    radius=radius,
                    color=GREEN,fill_opacity=0).move_arc_center_to(A0)
      arc_clockwise = ArcBetweenPoints(start=end,
                    end=start,
                    radius=-radius, #negative radius
                    color=YELLOW,fill_opacity=0).move_arc_center_to(A0)
      c=Circle(radius=radius,stroke_opacity=0.5,color=WHITE)
      self.add(c)
      self.play(Create(arc_counterclockwise))
      self.play(arc_counterclockwise.animate.set(stroke_opacity=0.5))
      self.play(Create(arc_clockwise))
      self.wait()

I changed the start end end point and made this radius negative.
