In sd_tricia I want the capture zone to signal a helicopter to fly into the map and slowly descend until it lands, upon which the team with the Australium can deliver it. Most of it I've got down, but the bit I can't figure out is how to set it so: The helicopter descends when the flag carrier is on the capture zone, The helicopter ascends to a certain point above the map when the flag carrier is not on the capture zone, And the helicopter pauses its descent when the capture zone has both the flag carrier and at least one enemy on it. (And as a bonus: for the helicopter's descent rate to vary depending on how many people are on the capture zone.) Functionally it's not dissimilar to the rocket lift in Doomsday I guess, but last time I made a Special Delivery map - being the hack that I am - I just copied the entities straight from Doomsday and pasted them in, so I have no idea how that works either. Halp.
