title: How should I calculate the speed of a Lerp?
body: <p>I have a Vector2 Lerp statement:</p>
  <pre class="lang-cs prettyprint-override"><code>Vector2.Lerp(spawnPos, target, position);
  </code></pre>
  <p>The <code>position</code> variable is a number between 0 and 1, and for all intents and purposes, it increments over time. Think of the way I'm tracking <code>position</code> as a &quot;playhead,&quot; like in music or animation, where a cursor moves from left to right as the playback continues.</p>
  <p>I want the object to continue moving <em>after</em> it reaches its target, at the same EXACT speed, just infinitely in a direction. I've tried to change the target to the direction multiplied by the distance between the spawn point, but I still can't figure out how to get the correct speed.</p>
