Hey, thank you for your feedback.

On an empty helicopter you can use
player action ["collisionlightOn", VEHICLE]
for collision lights and
player action ["lightOn", VEHICLE]
for the search light.

The AI will however manage the lights on its own depending on its current behavior and the searchlight is not included.

Will keep you informed.

Thank you.

@oukej,

This is unfortunately not the case from attempting to use this feature. It works as described for every vehicle EXCEPT helicopters (and i am told by others all pilots).

whilst the command you posted DOES turn the light on, the AI pilot turns it off after 0.2 seconds.

The only current solution is to turn it on every 0.01 seconds via a sleep loop, which is not appropriate!

It does not matter what behavior your set it to, even in careless helicopters still turn off the search light (but leave the collisions on).

setting the unit, or yourself as captive makes no difference either (or both!).

Any news? =)

Yes, although not directly a fix for the broken AI:

we found a solution that doesnt require a sleep command.
Create a script file and get the helicopter to exec that script.
In the script file put:
_type = typeOf _this;
_copy = _type createVehicle getPos _this;
_copy attachTo [_this, [0,0,0]];
_copy setPilotLight true;
_copy setCollisionLight true;

where _this is the chopper (dont need to rename the choppers, the _this is just for the script to work).

It clones the chopper, without a pilot and turns the lights on and attaches it to the existing chopper. In the first post (my post linked above) I found that waiting for ~30 seconds (sleep 30) after the chopper takes off before attaching the clone worked best -> sometimes they would explode if the ground was not perfectly flat, but in the air it wasnt an issue.

In summary to the Dev that posted: The AI Pilot will NEVER choose to leave the search light on with that command. No matter how you tweak it, the pilot AI turns it off (even if your both on the same side or captive).
