i just need to create a bot that repeats what i type in and changes its expressions accordingly.

Not sure what you mean by “changes it expressions” but if you mean it displays a happy picture when you say something like, “be happy” then this should repeat your input and display an imgae.

<category>
<pattern>_</pattern>
<template>
<star/>
    <think>
        <set name=“inp”><star/></set>
    </think>
    <condition name=“inp”>
        <li value=“BE HAPPY”>(display url for happy image)</li>
        <li value=“BE SAD”>(display url for sad image)</li>
    </condition>
</template>
