A roguelike toolkit in JavaScript

<h2>Event queue</h2>

<p><code>ROT.EventQueue</code> is a very simple tool to maintain a sorted priority list. It offers basic API for adding, removing and retrieving stuff. For most scenarios, the Event queue is too low-level and you might want to use a specific <a href="#timing/scheduler">scheduler</a> instead.</p>

<p>Time units in Event queue are abstract and do not need to be integers. The <code>getTime()</code> method can be used to retrieve the amount of already elapsed time units.</p>

<div class="example">
var queue = new ROT.EventQueue();

queue.add("event 1", 100); /* queued after 100 time units */
queue.add("event 2", 10);  /* queued after 10 time units */
queue.add("event 3", 50);  /* queued after 50 time units */

queue.remove("event 2");
SHOW(
	queue.get(),
	queue.get(),
	queue.getTime()
);</div>
