Invisible type list idea

What if invisible or invisibility was a list of type's or pointers?

For example,

mob
    iDisappear
        Click()
            usr << "I go poof!"
            usr.invisibles += src
            sleep(20)
            usr << "... and I come back!"
            usr.invisibles -= src


Or

turf
    yellow_flowers
        Click()
            usr << "You can't see us!"
            usr.invisibles += /turf/yellow_flowers
            sleep(20)
            usr.invisibles -= /turf/yellow_flowers


Basically, anything in this list would not be visible to the client.

Feel free to expand this idea...

It's been suggested a few times before to pretty high regard but not much came of it. For now though you can use Visibility Groups by Forum_account.

I think types and actual references are fine... I'm not sure how much overhead there would be to support ANY value, but it doesn't seem necessary. You almost always have access to at least the type path or the actual reference if you know you want something to be invisible.

I think some of the processing is handled on the client. If your instance of Dream Seeker knows the invisibility value for each atom and your see_invisible value, it can easily determine what you can and can't see. The more complex this gets, the more information your client has to have.

As Nadrew mentioned, the Visibility Groups library can easily handle this:

obj
    yellow_flower
        New()
            ..()
            
            // add this object to the "yellow flower" group
            vis = new(src)
            vis.is_a("yellow flower")
        
        Click()
            // remove the mob's ability to see yellow flowers,
            // then add it back.
            usr.vis.cant_see("yellow flower")
            sleep(20)
            usr.vis.can_see("yellow flower")

mob
    New()
        ..()
        
        // make mobs able to see yellow flowers by default
        vis = new(src)
        vis.can_see("yellow flower")
