Editing Understanding SS13 code (section)

=== Map editor ===

Usually opened at startup or when opening a ".dmm" map file, the map editor displays the map. By default it displays all 4 major groups: area, mob, object and turf. To choose the specifics of what to display, hit the layers tab in the top-most toolbar and select 'Only show selectable layers' and then choose which layers you want to be shown in the same (layers) tab. (Most commonly used to hide the areas overlay). Note that the map will not display if there are any errors in the .dm code. Correct any errors and then recompile it.
