CYO lets you create exciting adventures using nothing but HTML code!
See how it works at the project page.
- Version 3.1 is a huge update that completely revises CYO - now way easier and simpler to use!
- CYO 3.1 is no longer dependent on angular.js - just copy the script tag (see Getting Started) and you're good to go
- Improved performance all around
Getting started couldn't be easier! Just copy this script tag onto your document.
<script src="https://raw.githubusercontent.com/danielstern/cyo/master/cyo.js"></script>Now you're ready to add <story>, <page> and <choice> tags to your web page!
Follow the tutorial to get started with your project
Also known as "The Directives", wherein an interactive adventure is created, and Javascript (and Angular) fume about not being needed.
You can use these tools freely in your project to create your own interactive story adventure.
The story tag initializes your story by pointing to your first chapter.
You initialize your CYO with a simple story tag.
<story>
And a splendid story it will be.
</story>This element has to contain all the other elements. You can have multiple stories on a single page.
Pages are hidden automatically and appear when choices are pressed.
<page>
<p>
You see a grizzled old man tending a hearth.
<i>Something doesn't feel right here.</i>
</p>
</page>Choices are what make the storytelling process interactive. Clicking a choice will reveal the corresponding page.
<page>
<p>You see a fork in the path. </p>
<p>*Hmm... should I go left or right?*</p>
<choice go-left>Guess I'll go left.</choice>
<choice go-right>Right, definitely right.</choice>
</page>Events allow you to remember something special happening, for use later in your story.
<p>You find a flashlight.</p>
<event found-flashlight></event>event tags are powerful tools that are automatically remembered for the whole story. They can change what the user sees and what choices they have when used in conjunction with the equally simple condition tag.
Condition tags will show or hide content conditionally, perfect for use in combination with the event tag.
condition tags will show or hide the content inside them based on event tags that the storygoer has previously encountered in their adventure.
<p>Suddenly, you hear a terrifying noise.</p>
<condition found-flashlight>
<p>Don't be afraid, for the night is dark and full of terrors.</p>
<choice use-flashlight>Turn on your flashlight</choice>
</condition>
<choice run-away>Run for it!</choice>In this example, if the storygoer had previously found the flashlight, they would see another paragraph and have the option to use their flashlight, going to the use-flashlight page.
You can reverse a condition to its negative by adding the word not
<p>
The tall gate is locked and made of heavy iron bars.
</p>
<choice go-home>These guys are closed.</choice>
<condition not pocket-knife-broke>
<p>
"Don't worry... we can use my trusty pocket knife!"
<p></p>
"Don't you mean your *rusty* pocket knife?"
</p>
<choice break-lock>Looks like they're not closed after all.</choice>
</condition>The markup of your typical page looks like this.
<page exploring-the-house>
<p>
The floor creaks as you step into the house's massive foyer. Grimy paintings
of gaunt and ghastly figures line the walls, and go all the way up to the
ceiling. There is table in the middle of the room.
</p>
<p>
"Looks like Sal already got this room pretty good," says Brad nervously.
</p>
<p>
"Looks like it."
</p>
<!-- The following paragraph will only appear if you got the necklace in
chapter one -->
<condition get-necklace>
<p>
The figures in the wall all seem old and tired. Rarely are they smiling.
Many of the men have long mustaches. You notice someone familiar in one of
the paintings.
</p>
<p>
<i>That's impossible.</i> Suddenly, you reach for the necklace in your
pocket and pop it open. Sure enough. The woman is clearer in the picture.
She is has blonde hair and a striking face. She is not smiling in the
picture on the wall either. Below the picture you see the words <i>Eliza
Bedford.</i>
</p>
<!-- Your character learns Eliza's name and this comes in handy later. This
event never triggers if the condition it's inside isn't fulfilled. -->
<event learned-elizas-name></event>
<p>
"What are you looking at?" asks Brad.
</p>
<p>
"Nothing."
</p>
</condition>
<p>
The room has a dreary air of sadness about it. The wallpaper, purpled with
time, peels from the walls. Engraved candlesticks stand guard in neatly
ordered rows all around upper wall of the massive room. <i>Those look
valuable. A wonder someone hasn't taken them yet.</i>
</p>
<p>
"Well, boys," says crazy Jake, rubbing his hands together. "Let's not get too
comfortable."
</p>
<p>
"I'm going to look upstairs," says Brad. "Get a handful of jewels and get out
of here."
</p>
<p>
You get a weird feeling in your stomach. You can't figure out what it is.
</p>
<!-- This page ends with two choices thereby allowing the story to go on
as a new page is loaded. -->
<choice go-with-brad>Go with Brad</choice>
<choice go-with-jake>Go with Jake</choice>
</page>Once you click a choice, all the other choices on the page disappear.
Please use this tool to make your own adventures and share them. If you have any questions, or need a new feature to complete your latest epic, post it up here. Better yet, add the feature yourself and make a pull request.
I'd be happy to link to it on the project page! Get in touch with me @danieljackstern or [email protected]
Happy adventuring!
