Hi, I'm trying to create a mission where the player is ordered to got to a bay in the Philippines. Once he arrives at the zone he is ordered to pick up a spy in a lifeboat.
Having done that he has to take him to a zone about 100km away and meet a destroyer and hand him over.
Please can someone explain how I do the following?
(a) Not let the skipper know about the pickup until he reaches the bay. (i.e not show objective on mission orders until told)
(b) Not let him know about the rendezvous with the DD until the spy has been picked up.
(c) Call mission a failure if he doesn't reach the rendezvous zone by a certain time or a completion if he does.
I guess it's down to objectives, triggers and events but in what order do they take effect?
I've done several missions that work well so understand the basics, it's just a bit more complicated.
Thanks in advance.
