Proc Details

proc
find_atom
()

Finds the atom in the appropriate list that the selected var indicates

The selected var holds a REF, which is a string. A mob REF may be something like "mob_209". In order to find the actual atom, we need to search the appropriate list for the REF string. This is dependant on the program (Lifeline uses GLOB.human_list, while Fission360 uses GLOB.poi_list), but the result will be the same; evaluate the string and return an atom reference.

proc
scan
()

Runs a scan of all the trackable atoms.

Checks each entry in the GLOB of the specific trackable atoms against the track() proc, and fill the objects list with lists containing the atoms' names and REFs. The objects list is handed to the tgui screen for displaying to, and being selected by, the user. A two second sleep is used to delay the scan, both for thematical reasons as well as to limit the load players may place on the server using these somewhat costly loops.

proc
track
()

Updates tracking information of the selected target.

The track() proc updates the entire set of information about the location of the target, including whether the Ntos window should use a pinpointer crosshair over the up/down arrows, or none in favor of a rotating arrow for far away targets. This information is returned in the form of a list.

proc
trackable
(/atom/movable/signal)

Checks the trackability of the selected target.

If the target is on the computer's Z level, or both are on station Z levels, and the target isn't untrackable, return TRUE. Arguments: *arg1 is the atom being evaluated.
