Dynmap-Towny provides a simple way to add visibility of Towny towns and nations on Dynmap's maps. The plugin depends on the presence of both Dynmap and Towny Advanced, and interacts directly with the Towny API. Updates to zones are automatically processed (on a settable period - default is once per 5 minutes (300 seconds)). By default, the plugin will be active after simply installing it (by unzipping the distribution into the plugins/ directory and restarting the server).
Towns of any shape are supported, and a proper outline border is computed and displayed that will encompass all the contiguous blocks of a given town (limitation - 'holes' in the middle of a town may still be shaded to look like part of the town). Outposts, including outposts on other worlds, are supported. Clicking on the town will display a popup with a configurable set of data on the town.
Dynmap-Towny will also show configurable icons for the home block of each town, including distinctive icons when the town is a capital of its country.
Display style, including the color and opacity of the outlines and fill, as well as icons used for home markers, can be tailored. This can be done at the global default level, the per-nation level, or the per town level. The Y coordinate (altitude) of the town outlines can also be set (default is 64 - standard sea level) - typically this would be done using 'custstyle', to set the value for each town needing to be adjusted individually.
