Radar is a tool for finding units (mobs/items) around you which meet certain criteria. The first revision will look for uncollected lore items: datacubes, journals and TFBTF pieces. When any are found, a window will appear which lists all applicable units in range. Clicking on one of the units will display a standard quest-objective hint arrow pointing to the unit. There is also a 'Ping All' button; when the button is clicked, the hint arrows will repeatedly display for all nearby units on Radar. In addition, Scelestic got enthusiastic about the idea and contributed code for a 'filter' system, so units with a given word in their name can also be spotted.

When no units that Radar cares about are in range, the Radar window will vanish again.

The commands are as follows:

/radar on

Enables the popup 'radar' window, which will appear only when units are in range

/radar off

Disables the popup 'radar' window.

/radar options

Shows the Options window.

/radar ping

Will 'ping' (i.e., show a hint arrow) for all currently in-range units (whether or not the radar window is up).

/radar filter add <word1> [word2... wordn]

Will add a filter for the given words, where units whose name contains that will be shown. For instance, "/radar filter add Titanium" will cause Titanium nodes to also show on the Radar.

/radar filter remove <word1> [word2... wordn]

Removes the given filters.

/radar filter dump

Shows the currently-used filters.
