Enemy Mortar Fire When Player in Radius

[MANTIA 55]

I want to create a scenario where enemy mortars are firing on a COP or FOB where the mission is to located the enemy mortar tubes and eliminate them.

I want the players to have to recon and track where the sound from the mortars are firing in order to locate the tubes.

So I was thinking of having the enemy mortar tubes fire when players enter a radius via a trigger. However, I'm stuck on how to make an enemy AI mortar team fire on a target when a players enters the radius.

Any ideas?

Look up the commandArtilleryFire command and use that in the onAct field of the trigger.

"fireMortar.sqf"

_mortar = _this select 0;
_targetArray = _this select 1;

_target  = _targetArray select 0;
_theAmmo  = getArtilleryAmmo [_mortar] select 0;
_idx = 0;

//-- prevents firing at aircraft
if(isTouchingGround _target) then {	

//-- The number of times you want the _mortar to check for range
while {(_idx < 8)} do{
	_tgtPos = position _target;
	_isInRange = _tgtPos inRangeOfArtillery [[_mortar], _theAmmo  ];

	if (_isInRange) then {
		_mortar commandArtilleryFire [_tgtPos, _theAmmo  , 1 ];			
	};

	sleep 5;
	_idx = _idx + 1;
};	
};

so with this sqf the mortars would fire on hostiles within range correct? is there a way to get them to fire on a marker?

[Heeeere's johnny! 51]

_mortar commandArtilleryFire [getMarkerPos "someMarker", "8Rnd_82mm_Mo_shells", 3]

[MANTIA 55]

works perfect!

is there a way to add a delay in between the firing?

I found a few threads similar but it looks like the discussion was with Arma2 and it doesnt seem to work for me.

You could split the shots up:

for "_i" from 1 to 3 do
{
   _mortar commandArtilleryFire [getMarkerPos "someMarker", "8Rnd_82mm_Mo_shells", 1]
   sleep 10;
};

But don't forget used that code only inside a spawned block.

Where would I put this code? I'm guessing not in a units init line?

Actually, MiguelDarius has already given an example which kinda does as you desire. But just for you, here's a neat summary:

Where do I put this code? mission init file?

For example.

[MANTIA 55]

He only fires one time. Any way to repeat this every 30 seconds or so?

I tried another similar type of loop

{

_mortar = missionNamespace getVariable "mortar1"; //however you identify the mortar

_ammo = getArtilleryAmmo [_mortar] select 0;

_targetPosition = getMarkerPos "marker1";

_isInRange = _targetPosition inRangeOfArtillery [[_mortar], _ammo];

my value = 20;

while (myvalue > 0) do

{

myvalue = myvalue - 1;

sleep 2;

hint format ("%1",myvalue);

_mortar commandArtilleryFire [_targetPosition, _ammo, 2];

sleep 5;

};

};

and still it only fires once and doesnt display any of the hint as well .

The concepts in the following thread link may be of interest, as I was working a similar issue, but hit a wall with what I think may be command dynamics, but I'm unsure and haven't looked at it again since.
