title: AnimationCurve.Evaluate - Get time by value
body: <p>Is there a build-in way how to get a time by value from Animation curve in Unity3d? (The opposite way of Evaluate)</p>
  
  <p>I need to achieve this (instead of getting value from time):</p>
  
  <pre><code>float time = AnimationCurve.Evaluate(float value);
  </code></pre>
  
  <p>Generically speaking getting X value from Y value.</p>
