title: Godot - Get physics fps from script?
body: <p>So I want to set a speed in pixels per second and then calculate how much to move that specific physics frame. something like <code>const speed = 500 / get_physics_fps()</code>, I could in fact just do:</p>
  
  <pre><code>func _physics_process(delta):
      var speed = 500 * delta
  </code></pre>
  
  <p>but it feels like kind of a waste to calculate every frame something we know isn't going to change, also I can just divide by 60 or whatever I set my physics fps to, but that would be kind of harder to mantain than it needs to be.</p>
