Default value
null
This is the icon file that will be used to represent the object on graphical clients.
turf/wall
icon = 'wall.dmi'You can also assign this to an external file at run-time with an expression such as file(“wall.dmi”), but you would only want to do that when the other method is not possible, because it requires addition of the file to the resource cache, which can take a little time.
When this variable is set to any dynamically created icon object, that object gets dumped into the world’s resource cache (the .rsc file), and a reference to that cached file is assigned to atom.icon. In other words, don’t expect comparisons such as usr.icon == MyDynamicallyCreatedIcon to work unless you have used fcopy_rsc() to get a cache reference to your dynamically created icon first. This is almost never an issue, so don’t worry about it if none of that made any sense to you!
