How to make AI mortar fire at position?

[roguetrooper 2]

How can you make an AI-controlled mortar (not subordinated to human player) to fire at a certain position?

I've tried a hundred variations with these and related commands. Nothing works. The mortar moves some degrees but nothing happens.

enableEngineArtillery true;
(gunner mortar) commandArtilleryFire [[position tower select 0,position tower select 1,0], "Sh_82mm_AMOS", 1];

[jshock 513]

yourMortarNameHere commandArtilleryFire 
[
  getPosATL tower,
  "8Rnd_82mm_Mo_shells",
  1
];

I'm bumping this topic as it fits exactly my issue.

 

Even using @jshock 's script, they won't fire. It seems that they aim the correct way, but they won't actually fire.

 

I've tried the ammo type above, as well as the ammo types specific for the mortar.

 

Any ideas? Also, the mortars aren't vanilla, if that helps.

Make sure the mortar is actually able to fire at its target position.

Optimum distance to the target location would be anywhere between 250-4000m.

Place and mount a mortar near the AI mortar to check for yourself.

Appreciate the quick reply. I tested this out as well. I could shoot well beyond the distance required on the default range setting, and even moved the named target objects closer, with no luck.

 

Here's what I've got, in a script run by the game logic on mission start:

 

mortar1 commandArtilleryFire 
[
  getPosATL mortar_target1,
  "ARTY_LIB_8Rnd_81mmHE_GRWR34",
  5
];

I've tried doArtilleryFire as well to no avail.

Try using this:

 

_arty = mortar1;
_target = mortar_target1;

_artyAmmo = getArtilleryAmmo [_arty] select 0;
_artyETA = _arty getArtilleryETA [getPosATL _target, _artyAmmo];
_inRange = (getPosATL _target) inRangeOfArtillery [[_arty], _artyAmmo];
systemchat format ["In range: %1",_inRange];

if (_artyETA > 0 AND _inRange) then {

systemchat "Cleared to fire!";
systemchat format ["Impact ETA: %1s",_artyETA];
_arty commandArtilleryFire [getPosATL _target, _artyAmmo, 5];

};

There's already checks available to see if the arty piece is able to hit that position, use them.

Cheers.

 

Edit: Script now says they are in range and provides the ETA; however, they still aren't firing.

 

The AI adjusts his mortar to the correct direction, but won't fire.

Edit working fine here.

Has _arty got ammo?

 

_arty setVehicleAmmo 1;

Yes, they're filled to the brim.

What mod are your arty units from?

I saw same behavior for custom mortar (Iron Front's german mortar) with analogous code, while same code for sure works fine with vanilla artillery (and some other mods too IIRC). So indeed main question here is about the mod. Or, to be exact, why artillery from some mods doesn't work with these script commands and how to fix them.

It is actually the German mortar from Iron Front.

When you name the Arty make sure you name the Mortar  and not the AI or group.

 

Also just try placing a firemission  waypoint for the artillery  and see if that's working if it isn't then it's either mods or Arma3 installation.

Yeah, still no beans.

 

 

If I could just create the mortars without the AI firing them off, I'd be very happy with that as well; even explosions with a mortar whistle sound effect would do - think you could point me to some you'd recommend?

Tried it with the GrWr 34 mortar from iron front lite.

Like SkillerPenguin stated, the mortar aims, but doesn't fire.

Seems to be some config problem with the mortar.

It's official - after some testing, it officially looks like the Iron Front German & Soviet mortars don't work for AI. I put Germans in modern mortars, which worked but modern soldiers in German mortars didn't work.

 

Got any scripts handy for mortars hitting a target without needing an actual mortar?

 

[Grumpy Old Man 3546]

You could spawn in mortar shells around your marker position, and even randomize impact position using getRelPos.

Don't know about now, but in Arma 2 times there was at least few/several threads showing, how to. Same code with only changed ammo class should work in Arma 3. Two examples:

Give this a go, by no means perfect but it expands on what @Grumpy Old Man mentioned:
