using createvehicle with mq-9 predator problem.

[Rough Knight 9]

Hi guys,

I am at a loss with this one, however I Am sure there is a solution.

Because createvehicle creates an empty vehicle, I think this makes it nearly impossible to create a flying predator that can then be issued waypoints.

All my attempts have just created an airbourne predator that spirals and crashes. I'll attach some code and if anyone can point me in the correct direction I would appreciate it greatly.

In the 'init' field of my origional mq-9 I have the following:

nul = [this, "mq9spawn", "patrol1", 5] execVM "mq-9_1.sqf"

// mq-9_1.sqf
// Script for generation of MQ-9.

_unit 			= _this select 0;
_spawnpoint 		= _this select 1;
_marker                 = _this select 2;
_delay1                 = _this select 3;

sleep 0.1;

_veh1 = createVehicle ["MQ9PredatorB", getmarkerpos _spawnpoint, [], 0, "FLY"];

_veh1 enableAI "move";

[_veh1] join grpNull;
sleep 0.1;

_veh1 action ["engineOn", _veh1];

_veh1 setdir 45;

nul = [_veh1, _marker, "noslow", "nowait"] execvm "ups.sqf"; 

_veh1 flyInHeight 800;

Thanks

psst... no crew.. :)

If you'd like, You can either use my script, or see how I spawn a MQ-9 with crew allready using BIS's spawn vehicle function.

Yep, any flying vehicle (even cruise missiles) need a pilot to fly it. :D

Thanks guys,

Got it working. Sorry but it defied logic to me to have to spawn a driver and movein driver him to an unmaned drone in order for it to be able to fly:butbut:

PS: I am pretty new to scripting so please excuse any mistakes in the script or improper layout etc.

It's because the driver unit has AI/brains, the vehicle it is in is just a dumb, static object. It's an game engine limitation.

[Big_Daddy 10]

Hmm. just a question. What are you planning on doing with this UAV?

[Rough Knight 9]

Yo Big Daddy,

The purpose of this script was not to use the actual UAV as a interactive device, but to spawn the UAV and then create triggers at certain markers.

If the UAV flys within a set distance of the marker (objectives) then the player gets his map updated with the location of the objectives.

Just a simple concept and the UAV actions are only simulated, but it does what I want it to do : )

I did have to modify the setfriend portion of the script above because it took me ages to figures out why the newly spawned UAV's where crashing. They where basically trying to engage the enemy and turned into stuka dive bombers :mad:

This script may not be usefull to most...but is ok for my kind of mission. Hopefully I will post a beta of the mission in the forum next week.

Thanks

_uavpilot setVehicleInit format ["%1 = this;this disableAI ""AUTOTARGET"" ; this disableAI ""TARGET"" ; this setCombatMode ""BLUE"";this setBehaviour ""careless"";",_name1];

btw, here's the anti divebombing part of being a UAV..

[Rough Knight 9]

Hey Big Daddy,

LOL...cheers mate thats a more sensible way of doing it :)

Thanks
