[ZScript] Check if Actor has a mixin

[difficultoldstuff]

Hello guys! After googling a bi- a LOT I came to the forums for hints & tips yet again. What I'm trying to do is detect if a certain actor has a mixin. Short example would be:

Code: Select all • Expand view

mixin class Worms {}

class Can : Actor
{
    mixin Worms;

    States
    {
        Spawn:
            ACAN A -1;
            Stop;
    }
}

A simple check like this:

Code: Select all • Expand view

Actor actCan = SomehowGetActor();
if (actCan is "Worms") {console.printf("we have worms!");}

errors out with an "Unknown class name Worms of type Object", so apparently that's a no go, and I'm fresh out of ideas.

Any kind of smart trickery I can implement to solve this problem? I'd have a ton of items in my project, some of them need a certain additional mixin for functionality, but building and maintaining a list of objects to compare each item to would seem like a slower, more mundane solution. Help and input appreciated as always, thank you for your time!

Mixins are basically a syntax-checked copy-paste, and by the time code is actually compiled they don't even exist anymore, so you can't do anything to check for them. It's hard to tell you exactly what to do without knowing your specific problem, but it's probably something involving virtual functions.

Gotcha, thank you! It was mainly just a thought experiment to do something "the lazy way around", ended up using a quick test against some classes and it works pretty much alright. It's good to clarify this tho, cuts down on research time.
