Overlays, basically.

I'm attempting to make a medal system, and of course, I'm already stumped. I'm trying to make the medal appear as an overlay, and if the medal exists, I want it to delete the overlay, add one to the icon state and add the overlay again.
obj
    Medals
        icon = 'Medals.dmi'
        icon_state = ""

mob
    player
        icon = 'player.dmi'
    verb
        Add_Medal()
            var/obj/Medals/T
            var/IS
            var/MN
            if(!T in src.overlays)
                src.overlays += T
                return
            if(T in src.overlays)
                IS = T.icon_state
                del T
                MN = text2num(IS)
                MN += 1
                src.overlays += T
                T.icon_state = "gold[MN]"
                return

The problem here is that an object isn't stored in overlays -- rather, a "snapshot" image is generated of a particular object, and that image is added or removed from the overlays list when the code specifies to add/remove the object.

Here's how I would do it:

mob
player
icon = 'player.dmi'
var/obj/Medals/medal

proc/IncreaseMedal()
if(!medal) //if we don't have a medal...
medal = new /obj/Medals
overlays += medal
return

//otherwise...
overlays -= medal
var/IS = medal.icon_state
var/MN = text2num(IS) + 1
medal.icon_state = "gold[MN]"
overlays += medal


(Might also be a good idea to have the following code:

Write()
//remove overlay before saving
overlays -= medal
..()
Read()
..()
//add overlay upon loading
if(medal) overlays += medal

...just so your overlay doesn't get "stuck" on a character on save/load.)

Well, I tried what you gave me Spuzzum, and most likely I messed up somewhere.... it adds the medal the first time I click the verb, but doesn't seem to do anything else...
obj
    Medals
        icon = 'Medals.dmi'
        icon_state = "gold1"

mob
    player
        icon = 'player.dmi'
    verb
        Add_Medal()
            var/obj/Medals/medal
            if(!medal)
                medal = new /obj/Medals
                src.overlays += medal
                return
            src << "1"
            src.overlays -= medal
            src << "2"
            var/IS = medal.icon_state
            src << "3"
            var/MN = text2num(IS) + 1
            src << "4"
            medal.icon_state = "gold[MN]"
            src << "5"
            src.overlays += medal
            src << "Done"
