A really simple little script which shows up waypoints in-game that might be useful for FREDers. Or might not be; to be honest, having finished implementing it it now feels like one of those ' "Sounds useful!" *Uses for 10 minutes* "lol, no this just gets in the way." ' things. But it's finished now and it might as well be released in case anyone does find it useful.
Installation:
EITHER:
Download attached file to [mymod]\data\tables, and press "Alt-1" in-game to activate.
OR:
Create a text file vws-sct.tbm in [mymod]\data\tables and copy and paste the following code into it. Then press "Alt-1" in-game to activate.
#Conditional Hooks
$Application: FS2_Open
$On Game Init:
[
vws = {} --Set up the global table for this script
vws.active = false --Start off with script inactive
vws.waypointradius = 20 --Radius of waypoints
vws.textbuffer = 5 --Spacing between waypoint and text
vws.key = "Alt-1" --Key pressed to (de)activate script
vws.waypointred = 128 --Red value of waypoint
vws.waypointgreen = 0 --Green value of waypoint
vws.waypointblue = 128 --Blue value of waypoint
vws.waypointalpha = 128 --Alpha value of waypoint
vws.linered = 128 --Red value of lines
vws.linegreen = 0 --Green value of lines
vws.lineblue = 128 --Blue value of lines
vws.linealpha = 128 --Alpha value of lines
vws.textred = 128 --Red value of lines
vws.textgreen = 0 --Green value of lines
vws.textblue = 128 --Blue value of lines
vws.textalpha = 255 --Alpha value of lines

$On Mission End:
[
vws.active = false --Stops the waypoints showing up during the loading screen after a mission restart; delete this line if you don't care about this and want the script always on
]
#End
Near the beginning are some options which should be simple enough for you to figure out if you want to tweak things.

Guess I won't need to place nav buoys on dynamic waypoints anymore. Thanks :)

I completely forgot we had dynamic waypoints! If you or someone else could get back to me on whether this script plays nicely with them (it should, but that's not always the same as does) that would be great. I tried to test it myself just now and couldn't get any of the sexps to do anything (except crash FSO once), so I must be doing something wrong.
