Hi!
Lately I have been looking for ways to get an ai helicopter sitting on a helipad to patrol a few waypoints before it comes back and land on the helipad. Not only that but I want it to be in a cycle so it will repeat this after maybe 1 minute on the ground.
Well, I found "Mando_heliroute_arma" and that script had all the things i could wish for. In the mission editor there is a heli, you as a passanger and 3 game logics named "dest1,dest2 and dest3".
init.sqf
titleText["Some soldiers are waiting for us inside Bagango stronghold", "PLAIN DOWN"];
_scr = [heli1,[getPos dest1],50, true]execVM"mando_heliroute_arma.sqf";
Sleep 1;
waitUntil {heli1 getVariable "mando_heliroute" != "busy"};
{_x assignAsCargo heli1} forEach units group soldier1;
units group soldier1 orderGetIn true;
waitUntil {{_x in heli1} count units group soldier1 == count units group soldier1};
titleText["We'll bring them to Vallejos's hotel", "PLAIN DOWN"];
_scr = [heli1,[getPos dest2],50, true]execVM"mando_heliroute_arma.sqf";
Sleep 2;
waitUntil {heli1 getVariable "mando_heliroute" != "busy"};
{_x action ["GETOUT", heli1];unassignVehicle _x} forEach units group soldier1;
Sleep 4;
titleText["And now a long travel to Rahmadi", "PLAIN DOWN"];
_scr = [heli1,[getPos dest3],50, true]execVM"mando_heliroute_arma.sqf";
Sleep 2;
waitUntil {heli1 getVariable "mando_heliroute" != "busy"};
heli1 setVariable ["mando_heliroute", "free"];
player action ["GETOUT", heli1];
titleText["T H E E N D ", "PLAIN"];
mando_heliroute_arma.sqf
/*********************************
mando_heliroute_arma.sqf v1.2
August 2007 Mandoble
Moves a chopper accurately to the desired destination point following the indicated route and land it if so indicated.
Execute it there were the chopper is local.
Sintax:
[chopper, route positions array, flying height, landing true/fasle] execVM "mando_heliroute_arma.sqf"
Route positions array is an array of at least one position that defines the route the chopper will follow.
Once it reaches the final destination it will land if landing parameter is set to true.
When the route is completed, the chopper will set its internal mando_heliroute variable to "waiting".
While the chopper is executing the route that variable is set to "busy" and, if the chopper is damaged or the pilot is killed, the variable is set to "damaged".
If you want to check when the route has been completed, you may do it this way:
Sleep 2;
waitUntil {heli1 getVariable "mando_heliroute" != "busy"};
if (heli1 getVariable "mando_heliroute" == "damaged") then
{
hint "Chopper damaged or pilot dead, not available for more routes.";
}
else
{
if (heli1 getVariable "mando_heliroute" == "waiting") then
{
hint "Chopper waiting for a new route.";
};
};

Thanks,
Edit:
I managed to get the heli to move between those waypoints and land again. But I am not looking at how to get the heli to seek and destroy.
// myinit.sqf
_scr = [heli1,[getPos dest1],75, false]execVM"mando_heliroute_arma.sqf";
_scr = [heli1,[getPos dest2],75, false]execVM"mando_heliroute_arma.sqf";
_scr = [heli1,[getPos dest3],75, true]execVM"mando_heliroute_arma.sqf";
heli1 setVariable ["mando_heliroute", "free"];
Edit: I managed to get it to work by using mandoble's heli attack script. And now the missions seems to run very nice with a randomly patroling heli.
