HTML How to setup a breeding system for a Twine management sim?

[PsyTurtle]

I'm working on a kinda management sim. I've been considering using Twine and Sugarcube. It's gonna be very text based and relatively bare bones for now, but I want to include a breeding system. Is there a Twine script or something anywhere for an easy breeding/genetics system? Any resources about how to set up something like that in Twine would also be appreciated.

I remember how to set this kinda thing up in RPG Maker VX Ace. But if I use RPGM, I'll get distracted and start trying to draw the player character and make maps. I don't wanna focus on that because I'm already doing graphic design stuff for another project. Apologies for any formatting errors, I'm posting this from mobile.

I assume an easy genetics system would mean randomly selecting traits from 2 sets of traits (parents) to create 1 set of traits (child).

You can either do this by creating a JavaScript function or by creating a SugarCube widget. A widget is basically a function except it cannot return anything, but you can always set a variable to your 'return' value and access it outside of the widget.

Example function:

setup.createChild = function (a, b) {
    const c = clone(a);
    for (const trait of Object.keys(b)) {
        if (random(1)) c[trait] = b[trait];
    }
    return c;
}

Example widget:

<<widget 'createChild'>><<nobr>>
    <<set _child = clone(_args[0])>>
    <<for _key, _value range _args[1]>>
        <<if random(1)>>
            <<set _child[_key] = _value>>
        <</if>>
    <</for>>
<</nobr>><</widget>>

And you could use them like so:

<<set $dad = {
    hair: 'brown',
    eyes: 'green',
    skin: 'light',
}>>
<<set $mom = {
    hair: 'black',
    eyes: 'brown',
    skin: 'dark',
}>>
<<set $child1 = setup.createChild($dad, $mom)>>
<<createChild $dad $mom>>
<<set $child2 = _child>>
