RE: prevent a chatbot from asking a question it knows

Note that scripts are executed before response patterns, so if you have an AIML script loaded in your bot for the same pattern, it will take precedence.

To do the same in AIML you could use something like,

<category>

<pattern>DO YOU LIKE *</pattern>

<template><self>if (star.like == null) { "what are " + star; } else if (star.like == true) { "Yes, I like " + star; } else if (star.like == false) { "No, I do not like " + star; }</self></template>

</category>

<category>

<pattern>YOU LIKE *</pattern>

<template>Okay, I will remember that I like <self>star.like = true; star</self></template>

</category>
