Helicopter Crash recovery

[glass32b 0]

Hello out there,
 
I am new to the whole Arma 3 editing.  so far it has been very interseting building my own missions and its very fun to play other people's missions as well. 
So a friend and I are trying to create the PB we lived on when we were in Afghanistan it took a good while but we finally finished it.  Now we want to make some great missions but everytime we think of something we hit major walls because we have no idea what we are doing. 
 
So the mission is that you get ambushed in a city you then make your way to a clear exfill.  we have a helo extraction module for a transport request to be able to RTB.  when you call it in the helo flies over 8 AA infantry and most of the time the bird just crash lands but does not blow. 
 
what we want to see is this bird crash and as it crashes to the ground enemy forces are then triggered to secure the site. 
 
I would create a trigger so as the helicopter passes over the trigger it would sync with soldiers to preplanned waypoints.  the thing is that when this helicopter gets hit, it can land almost anywhere in a 3 square mile radius.  Plus sometimes the helo does not die.  I created a trigger with !alive joker command but when the bird safley lands after taking the hits the trigger never gets activated.  
 
So all in all I need to have enemies close in on a down helicopter and I want to be able to trigger the helo crashing with a hint.
 
Thanks in Advance.  
If you need to get a hold of my map please let me know.

Hi.

 

Instead of digging in editor put in joker heli init field :

nul = [this] execVM "crash.sqf";
this addAction["<t color='#ff9900'>Repair JOKER</t>",{
    _unit = _this select 1;
    _unit playMove "AinvPknlMstpSnonWnonDnon_medic_1";
    sleep 9;
    joker setDammage 0;
},[],6,false,true,"","alive joker && ((getDammage joker) > 0.1) && (_target distance _this) < 5"];

Then create file   crash.sqf  in mission root directory.

    private ["_joker", "_jokerGrp", "_crashsite", "_newpos", "_marker", "_marker2", "_enemyposition", "_enemygroup", "_enemygroup2", "_vehicles", "_trg", "_trg2", "_wp", "_landpos"];

    _joker setCaptive true;
