Help requested with two mission editor events

[Bahger 11]

[Apologies if you have read a similar post in the ArmA 2 Editor forum; I posted it there in error]

Building a single-player mission using the High Command module I cannot figure out how to:

- Get a helicopter that is under the player's control in High Command (and therefore has no pre-plotted waypoints) to RTB (i.e. leave the mission) when a mission trigger fires.

- Get enemy units to spawn in by the same trigger, or the trigger plus time delay, i.e. 30 sec after the chopper departs.

I'm sure this must be easy for many of you guys but I struggle with not having a coder's brain so the simpler you can make any explanation, the better for me. I would really appreciate your help, thank you.

i was able to have a trigger have a helo under player high command 'rtb' on trigger activation using doMove... in the trigger On Act -

heli1 doMove [0,0,0];
// replace [0,0,0] with your destination (can be variable or array like above)
// heli1 doMove _pos;

as for enemies, you could use BIS_fnc_spawnGroup; BIS_fnc_spawnEnemy (find in Arma Functions Viewer under category 'spawning.' this function requires 2 positions - player or friendly units, and a reference object; enemy will spawn on far side of reference), or createGroup

if still failing, double check you have your trigger setup properly

This is so helpful to me, dr, thanks a lot. With apologies for my non-coder's brain, q couple of quick follow-up questions:

- Can I use a marker name instead of those coordinates for the helicopter's RTB destination in the above script?

- As for the enemy spawn script, this works beautifully and does exactly what I want, all code in the trigger activation field with no need for a script document. Obviously you need all the right ArmA 3 class names, which I found here.

No apology needed, theres alot of info, and alot of it isn't clear or easy to find

yes, you'll need to use getMarkerPos. remember to put " " quotations around your marker name (marker names are handled as strings in -most- cases. more on markers: Command Group - Markers)

Thanks for your patience. This is a large-ish mission that is testing my meager scripting abilities to the full.

I'm about to start testing what I want to to with this group of two attack helps. As we have discussed, I want them to RTB and I will use the method you suggest but can you think of a relatively easy way I could get a group with no WPs but under High Command to RTB by timer in this specific way: 15 minutes after the player first calls on them via HC to maneuver or perform a task?

[dr_strangepete 6]

personally, i would just spawn a small timer when the player first calls, a timer that sleeps for 15 minutes and then issues the doMove command:

_nil = [_unit,_pos] spawn {sleep (15 * 60);_unit doMove _pos;};

[Bahger 11]

When the player first calls the helo, it's through the High Command module so my question is, how can I associate a trigger with this event?
