<p>The Graph that Generates Stories</p>
<p>StoryGraph is a graph designed to generate and narrate the causal interactions between things in a world. The graph can be populated with entities and expressive rules about the interactions between specific entities or different classes of entities. General rules can create new entities in the graph populated with the specific entities that triggered the rule and attributes defined by those entities. Entities have lifetimes and (coming soon) behaviors that trigger events over time.</p>
<p>Story graph is inspired by <a href="http://www.cs.cmu.edu/~cmartens/thesis/">progamming interactive worlds with linear logic</a> by <a href="http://www.cs.cmu.edu/~cmartens/index.html">Chris Martens</a> although it doesn’t realize any of the specific principles she develops in that thesis.</p>
<p>There is a more or less fleshed out example in ./example.js that produces sometimes surreal interactions in a snowy forest. To run that example, clone the repo and run the example directly with node.js:</p>
<pre><code class="language-shell">$ node example.js
</code></pre>
<p>You will see output something like this:</p>
<pre><code>The river joins with the shadow for a moment. The river does a whirling dance with the shadow. A bluejay discovers the river dancing with the shadow. A bluejay observes the patterns of the river dancing with the shadow. A bluejay dwells in the stillness of life. A duck approaches the whisper. A duck and the whisper pass eachother quietly.

<p>The first step is to define types. While it is possible to make rules that apply to specific things, you’ll probably want to make general rules that apply to classes of things. First the basics:</p>

[]string{`<p>The Graph that Generates Stories</p>
<span style="background-color: lightpink; text-decoration: line-through;">
</span><p>StoryGraph is a graph designed to generate and narrate the causal interactions between things in a world. The graph can be populated with entities and expressive rules about the interactions between specific entities or different classes of entities. General rules can create new entities in the graph populated with the specific entities that triggered the rule and attributes defined by those entities. Entities have lifetimes and (coming soon) behaviors that trigger events over time.</p><span style="background-color: lightpink; text-decoration: line-through;">
</span>
<p>Story graph is inspired by <a href="http://www.cs.cmu.edu/~cmartens/thesis/">progamming interactive worlds with linear logic</a> by <a href="http://www.cs.cmu.edu/~cmartens/index.html">Chris Martens</a> although it doesn’t realize any of the specific principles she develops in that thesis.</p><span style="background-color: lightpink; text-decoration: line-through;">
</span>
<p>There is a more or less fleshed out example in ./example.js that produces sometimes surreal interactions in a snowy forest. To run that example, clone the repo and run the example directly with node.js:</p>
