I think I know what to do here, but the code I first tested has som serious problems... I just want to restart it entirely. How would I write the Click() proc for a save hud button? It must save location, icon_state, variables, and overlays. Any Ideas?

obj
    hud
        Save
            icon='HUD.dmi'
            icon_state = "Save"
            screen_loc="15,1"//when it is moved to someone's screen, it's loc is 15,1
            Click()
                var/savefile/F = new(usr.ckey)
                F["last_x"] << usr.x
                F["last_y"] << usr.y
                F["last_z"] << usr.z
                Write(F)
                usr<<"Saving..."
                sleep(20)
                usr<<"Your progress has been saved."
//Writes savefile


and...

            if("Load")
                var/savefile/F = new(usr.ckey)
                Read(F)
                var/last_x
                var/last_y
                var/last_z
                F["last_x"] >> last_x
                F["last_y"] >> last_y
                F["last_z"] >> last_z
                loc = locate(last_x, last_y, last_z)
                usr<<"Your character has been sucessfuly loaded."
//reads savefile

And I also put it on the screen, that's the easy part.

I'd suggest making a save and load proc first, and then make the hud button call the procs.

Thanks. I have a save verb, but I can't call that.

Uh, calling Write(F) is all fine and dandy, but you're not supposed to be saving the button (src), but the player (usr). Hence it should be usr.Write(F).

However, saving last_x/y/z here is a bad idea. You should be doing that in Write() itself, not in your HUD. The HUD button should merely be an alternative way to access save functionality.

Likewise of course, Read() should be doing more work when loading than it currently does.
