Problem description:
So my next step is to program in character customization. But wait, I don't wanna do the character on map with Hud buttons I wan't to do it withins Byond's skin system. I am just wondering how would you go about this? What element would display the realtime usr.icon and allow overlays to be shown on it? Would a grid work or would it be a browser approach?
Best response
just create a dummy icon/image, add/blend the overlays to that image(hair, etc)

Output it/set it whichever way you desire:

output() //for sending it to a grid.
winset() //for setting it as a label and such
As far as I'm aware, there won't be any realtime updating, unless you update it yourself during runtime.
