How will you limit the number of possible jumps within 24 hrs.?
I'm not sure if FLHook is configurable that way - and if not abuse
might be too infatuating to resist and who will be "punished" to
controll all Barges logfiles every 24 hrs.?
This should be pretty easy. Create an integer (x) for every account with a barge who's base value is 0. When the jump has been used the value changes to 1. If x=1 do not allow jump. Whenever the server restarts the value will revert to 0. This is generally every 24 hours. You could probably do it based off of time as well, setting a time for every one of these variables to be reset automatically, as FLhook can access server time. That would require work though.
The real issue with this command would be that the barge could just fill up once every other day with mine-able commodities and then jump directly to the base with the highest buy price. This would be bad. Also these ships would only be seen in EW and maybe BW systems, but even that is pressing it. So if you could restrict the jump to those systems that would solve that problem, but it still doesnt solve the money making problem.
