If you want the vulcans to appear randomly, just "script" that into their initialization fields (or just turn the % slider around
), and that'll do it for that. Tell us more about your situation, maybe we can help. I.e:
You want 2-5 vulcans to appear with a random chance: -> Make 2 vulcans have a 100% presence, the rest whatever % you need. You want these vulcans to appear in random locations (random pre-defined ones, but not the same all the time, i.e., the two 100% would always appear anyway) -> do the old "group with marker" trick to get them to appear randomly. Although I guess that might lead to two vulcans appearing on the same marker with a bit of bad luck
Otherwise, some creative deleteVehicle'ing and scripting should get things done. The condition of presence field is a fickle mistress, and not really necessary. Useful for campaign scripting and stuff like "!cadetMode" and whatnot.
Wolfrug out.
