<div class="desc"><p>Binds a physical key (a character code such as <code>'w'</code> or <code>' '</code>) to a named <em>action</em>, creating the action the first time it is named. Gameplay then reads the action with <a href="input-down.html"><code>Input.down</code></a> / <a href="input-pressed.html"><code>Input.pressed</code></a> instead of a raw key, which is what makes rebinding and alternate control schemes clean. Call it more than once with the same action to bind several keys to it; binding a key already on the action is a no-op. Actions are advanced once per frame by <a href="input-poll.html"><code>Input.poll</code></a>.</p></div>
