Code:
turf
    MouseDrag(turf/a,turf/b)
        if(usr.building && usr.buildmethod == "Block")
            for(var/turf/T in block(a,b))
                T.overlays+=image('dither.dmi')
turf
    MouseDrop(turf/a,turf/b)
        if(usr.building && usr.buildmethod == "Block")
            for(var/turf/T in block(a,b))
                var/atom/A = new usr.buildtype(T)
                A.icon = day ? 'Day Turfs.dmi':'Night Turfs.dmi'
                T.overlays=null


Problem description:

Well, I am trying to make a building system using mousedrag and drop, The problem is When I am making the rectangle It adds overlays from mousedrag. But If I make the rectangle smaller than its greatest area, I don't know how to delete those overlays. Doe's anyone know how?

Wouldnt it be T.overlays-=image('dither.dmi')
or T.overlays.Remove(image('dither.dmi'))

Both entry of the above must be completed in order to bump, now you must be annihilated.
