<code class="sig">Math.move_toward(from, to, delta) -&gt; fixed</code>
<div class="desc"><p>Moves <code>from</code> toward <code>to</code> by at most <code>delta</code>, never overshooting — when the gap is smaller than <code>delta</code> it returns exactly <code>to</code>. Unlike <code>Math.lerp</code>, which eases by a fraction of the remaining distance, this moves at a constant rate, which is what you want for turrets, meters, and UI values that should approach a target steadily and then stop.</p></div>
