<p>Helper to handle on-demand requests, allowing a system to change state only when a player or system
actually needs the information. This is a very efficient way to handle gradual changes, requiring
not computer resources until the state is actually needed.</p>
<p>For example, consider a flowering system, where a seed sprouts, grows and blooms over a certain
time. One _could_ implement this with e.g. a Script or a ticker that gradually moves the flower
along its stages of growth. But what if that flower is in a remote location, and no one is around to
see it? You are then wasting computational resources on something that no one is looking at.</p>
<p>The truth is that most of the time, players are not looking at most of the things in the game. They
_only_ need to know about which state the flower is in when they are actually looking at it, or
when they are in the same room as it (so it can be incorporated in the room description). This is
where on-demand handling comes in.</p>
<p>This is the basic principle, using the flowering system as an example.</p>
<ol class="arabic simple">
<li><dl class="simple">
<dt>Someone plants a seed in a room (could also be automated). The seed is in a “seedling” state.</dt><dd><p>We store the time it was planted (this is the important bit).</p>
</dd>
</dl>
</li>
<li><p>A player enters the room or looks at the plant. We check the time it was planted, and calculate</p></li>
</ol>
<blockquote>
<div><p>how much time has passed since it was planted. If enough time has passed, we change the state to
“sprouting” and probably change its description to reflect this.</p>
</div></blockquote>
<ol class="arabic simple" start="3">
<li><p>If a player looks at the plant and not enough time has passed, it keeps the last updated state.</p></li>
<li><p>Eventually, it will be bloom time, and the plant will change to a “blooming” state when the
player looks.</p></li>
<li><p>If no player ever comes around to look at the plant, it will never change state, and if they show
up after a long time, it may not show as a “wilted” state or be outright deleted when observed,
since too long time has passed and the plant has died.</p></li>
</ol>
<p>With a system like this you could have growing plants all over your world and computing usage would
only scale by how many players you have exploring your world. The players will not know the
difference between this and a system that is always running, but your server will thank you.</p>
<p>There is only one situation where this system is not ideal, and that is when a player should be
informed of the state change _even if they perform no <a href="#id1"><span class="problematic" id="id2">action_</span></a>. That is, even if they are just idling
in the room, they should get a message like ‘the plant suddenly blooms’ (or, more commonly, for
messages like ‘you are feeling hungry’). For this you still probably need to use one of Evennia’s
built-in timers or tickers instead. But most of the time you should really consider using on-demand
handling instead.</p>
