i know how to do it
place a trigger where u want the chopper to be hit
name the chopper helo1. put in the on activ part
exec"scriptname.sqs"
scriptname is what u name the script below.
the c-130 addon by hawk has a very loud (if i was in a real c-130 and it went off i would be pretty scared) alarm tone so get that out by depboing it, while ur getting the alarm tone out of the addon also get the flare launching noise from it too.
make a script that basicly just
helo1 playSound "alarm tone"
~1.5
helo1 sidechat"Incoming missile!"
~1
helo1 playSound "flarelaunchsound"
~1.5
_blast ="Grenade" camcreate getpos helo1
~.7
helo1 SideChat"We're hit!"
~.2
[helo1]exec"tailrotor.sqs"
exit
somthing to that effect ;code not garenteed;
in the playsound"nameofsound" parts u must replace it with the actual names of the sounds from the C-130. and of course remember to put them in the description file with the mission.
and find the tail rotor script in the ed depot u will have to add other things like #of people in chopper to randomly die and stuff like that to the
[helo1]exec"tailrotor.sqs"
part
the effect(or so i hope, i am a worse scripter than u i was just trying to give u an idea ho to do it) if it works is when u hit the trigger in the chopper, an audio tone to warn of incoming missiles will sound, the pilot will yell incoming, then the flare launch sound will sound like the missle zooming in sound and the nade will give the boom, a little dammage and jolt the chopper. then the tail rotor script will activate.
i hope this helps,
