'Lo!
OK; I've got a little problem with a mission I'm building.  I'm trying to get enemy aircraft to spawn for the player's shooting pleasure; and to keep spawning every time he enters the airspace of a particular airfield.
So I set a 10nm. zone around the airfield; made enter and exit triggers for it. Enemy planes spawn no probs when I first enter; but:
Problem 1:If I set 'Abe' (the enemy) to 'Spawn'; he spawns once only even with 'Repeat when true' checked.
If I set him to 'Respawn"; he spawns as soon as his last incarnation hits the deck; even with 'repeat' unchecked.
I made sure the enter and exit triggers specified entering or leaving the area - not 'inside'; so it's a bit of a mystery what combo to use to get what I want.
But:
Problem 2: I want to have 'abe' keep spawning every time Player enters the area, until a given object is destroyed - in this case; a moving-object sub. IOW; Abe keeps attacking until player succeeds in destroying the sub, then abe stops spawning. So I created a trigger detailing 'sub, Object health greater than zero', and added it to the conditions. So Abe's spawning conditions are "Area Entered" and "Sub health".
Except the sub's health - probably caused by Problem 1 - seems to have no effect at all.
If I'm making any sense at all; does anyone know how to program the triggers/events to accomplish this? Thanx.

Hi

ckur on the right track.

You might try something like this:

If

Player in spawn zone
"Abe" health=0
"sub" health not =0

then

Delay 10 "make sure "Abe" dead"
spawn "Bob"

Also create a trigger for "Bob"

Player in spawn zone
"Bob" health=0
"sub" health not =0

then

Delay 10 "make sure "Bob" dead"
spawn "Abe"
