title: How to control display speed in manim?
body: <p>I found in manim there are two kinds of way to display animation, one way is to use<code>self.play()</code>and by adding <code>run_time = X</code>in <code>kwargs</code>, the speed of animation can be set and the animation will finish in X seconds.</p>
  <p>But I found another way to display by first adding an object with updater using <code>self.add()</code> and wait it to display using <code>self.wait()</code>.</p>
  <p>How to control the speed if use <code>self.add()</code> and <code>self.wait()</code>?</p>
  <p><a href="https://docs.manim.community/en/stable/examples.html#rotationupdater" rel="nofollow noreferrer">There is a demo to show the case</a></p>
  <p>BTW, I'm using manimgl instead of community version in order to achieve real time rendering.</p>
