Well, just wanted an opinion on the best way to cache these icons, I made a map2icon type of thing where the map is all put into 1 icon and to do this I have to make a new icon for pretty much every turf. Putting these icons in a cache wouldn't have been too hard if I wans't manipulating all of them, yea I'm adding a lot to these icons and changing them quite a bit depending on how many atoms there are in one location, any ideas?

Without any specifics there's no way you'll get a useful answer.

There isn't much information to give. Basically I need a way to cache icons without having the icons in the cache be changed after I indirectly manipulate them...Now I'm confusing myself :(

Code:

proc
    m_mapicon(var/Z=1, var/map_icon_size=16)
        if(!Z) return 0
        var/icon/return_icon = new('blank.dmi')
        return_icon.Scale(world.maxx*map_icon_size, world.maxy*map_icon_size)
        var/icon/temp
        var/icon/temp2
        var/turf/T
        for(var/Y=1 to world.maxy)
            for(var/X=1 to world.maxx)
                T = locate(X,Y,Z)
                if(!T) continue
                if(T.icon&&!Exclude.Find("[T.type]"))
                    temp = icon(T.icon, T.icon_state, frame=1)
                else
                    temp = new('blank.dmi')
                    temp.DrawBox(Empty_Color, 1, 1, temp.Width(), temp.Height())//This icon was changed
                temp.Scale(map_icon_size, map_icon_size)//this was changed
                for(var/atom/movable/A in T)
                    if(A.icon&&!Exclude.Find("[A.type]"))
                        temp2 = icon(A.icon, A.icon_state, frame=1)//Here I would use the cache proc...
                        temp2.Scale(map_icon_size,map_icon_size)//Changed Icon
                        temp.Blend(temp2, ICON_OVERLAY)//Changed Icon
                return_icon.Blend(temp, ICON_OVERLAY, X*map_icon_size-map_icon_size, Y*map_icon_size-map_icon_size)
        return return_icon

var/list/icon_cache = list()

proc
    Icon(file,state,dir,frame,moving)//icon cache
        var/a = "[file]_[state]_[dir]_[frame]_[moving]"
        if(icon_cache.Find(a))
            return icon_cache[a]
        else
            var/icon/I = icon(file,state,dir,frame,moving)
            icon_cache+=a
            icon_cache[a] = I
            return icon_cache[a]
