I stole half of this from mrangel and the other from HK

I never made a list of clones, because keeping it up to date ends up being a pain. Instead I put this.prototype = this in an object's init script. (I could do it in the start script, foreach (o, AllObjects()) { o.prototype = o }, but I seem to have ended up using the prototype in various places to check if an object is something my scripts can expect to see clones of.

So when I want to deal with them all, I can do something like:

<function name="FindClones" parameters="object" type="list">
  // Find all objects with the same prototype as the one passed in
  if (HasAttribute (object, "prototype")) {
    object = object.prototype
  }
  result = FilterByAttribute (AllObjects(), "prototype", object)
  return (result)
</function>

So then…

foreach (o, FindClones(KV)) {
  msg ("Here's one…")
  if (o = KV) {
    msg ("... but that's the original. Can't slap KV, that would be rude.")
  }
  else {
    DisposeItem (o.name)
    msg ("Clone slapped!")
  }
}

Aha!

And, yeah... I only stole the while (RandomChance(50)){ spawning clones bit from you.

HK showed me you could use x = CloneObject(KV) to clone KV and get the name of the clone, and I adapted that to the string list.

I like your responses better than mine, too. Hehehe.

Is this supposed to go to Enpherdaen?

What is up with that title, and those parentheses? Lol
