+  <div class="desc"><p><code>Update</code> is the everyday game-logic phase, run each frame after <code>Input</code> and <code>FixedUpdate</code> and before <code>LateUpdate</code> and <code>Render</code>. It is where most gameplay lives when you are not being strict about determinism: spawn waves on a timer, apply the intent that <code>Input</code> recorded, check win/lose conditions, advance animations. Reach for <code>Update</code> by default and reserve <code>FixedUpdate</code> for the simulation you specifically want reproducible. Because it runs after <code>Input</code>, the current frame's key press is already reflected in your program <code>var</code>s by the time <code>Update</code> reads them.</p></div>
