I made this code for a mod, it's a server-sided script that detects created shells or rockets and attaches a plane to them in order to make them targettable via radar. (In this case, I used a plane belonging to A3 vanilla in order to see it better, the real one has no model). The first two lines are just used to debug this via the console, plus some stuff I omitted. The issue is that when I fire a shell, I can see the plane briefly appearing and then it disappears and the shell isn't trackable, then once it explodes I see the "Deleted" message, whereas if I fire a missile I can see the plane being created and it's properly attached to it. The systemchat messages are: Local: true, Server: true, Owner: 0 (shells have 0 for ID, rockets have a number like 3 or 4) [193e96c6040# 414: plane_fighter_03_f.p3d] Deleted:193e96c6040# 414: plane_fighter_03_f.p3d There are no .rpt errors, I was wondering what could be the issue here since it works in SP and with rockets in MP... if(!isServer) exitWith {}; if(!isNil "lastId") then {removeMissionEventHandler ["ProjectileCreated", lastId];}; lastId = addMissionEventHandler ["ProjectileCreated", { params ["_projectile"]; if(_projectile isKindOf "ShellCore" or _projectile isKindOf "MissileCore") then { ("Local:" + str(local _projectile) + " - Server:" + str(isServer) + " - Owner: " + str(owner _projectile)) remoteExec ["systemChat", 0]; [_projectile] spawn { _projectile = _this select 0; sleep 0.1; private _localFake = "I_Plane_Fighter_03_CAS_F" createVehicle (getPos _projectile); _localFake allowDamage false; _localFake attachTo [_projectile, [0,2,0]]; [str (attachedObjects _projectile)] remoteExec ["systemChat", 0]; while {alive _projectile} do { sleep 0.04; }; ("Deleted:" + str _localFake) remoteExec ["systemChat", 0]; deleteVehicle _localFake; }; }; }];

It seems that when Shellcore projectiles are being used, the vehicle is created at [0,0,0] and it moves kinda weirdly in the air as if it tried to follow the shell but is stuck on the ground

So I made a mod where I created a vehicle and I used the vehicle's "init" event handler. From the event handler I remotely execute a function: [_this # 0] remoteExec ['function', 2, false]; The first line of the function contains this: if(!isServer) exitWith {} I'm being told that the script isn't running and I was wondering what was wrong with this, everything compiles and works in SP, but on MP (dedicated servers) nothing works. Could it be I need to setup CfgRemoteExec? Thanks.

Yes apparently switching it to if(!local _unit) exitWith {} fixed this issue, though I find it strange that it's not running on the server, my fear is that it will run for every client... On top of that, I have the same issue with a function set to postInit, it has the exact same structure and once again, it's not running. I do want to mention that I am using FASTER and I have set the mod to run on Server, Client, and Headless. Could this have something to do with the matter?

Hello, I recently made an Iron Dome mod: Steam workshop link I am also releasing a standalone script used for guiding the missile, currently, 3 modes are available: Augmented proportional navigation APN Proportional navigation PN Pure pursuit LOS Here is the code: You can call this function (script) by using: [missile, target, [parameters]] execVM...

This is a script I made that allows the vanilla C-RAM to attack incoming artillery shells. You can find the mod here: https://steamcommunity.com/sharedfiles/filedetails/?id=2825319340 or if you want 100% vanilla then use the following composition: https://steamcommunity.com/sharedfiles/filedetails/?id=2825313831 The target selection logic can be changed via action menu: Random Distance/Speed bias Thread bias: The system will engage the shell that is going to land the closest factoring time.

Hello, I am trying to re-create the Drone 40 UAV, I am looking for a modeler with some experience both with modeling and importing the stuff into Arma 3. (Animations)

Hello everyone, I'm currently in the process of making a "Drone 40" mod. The idea is to replicate the DefendTex UAV-40 autonomous grenade, soo far I've written all of the code in regards to its logic Showcase. The problem is that I have pretty much zero experience with modeling and have no idea how to import one into the Arma engine, thus I am looking for a modeler to help me with this (mainly the import aspect, model -> p3d). If you're interested we can talk about this further.

Hello everyone, I'm making a mod that adds a special mine, soo far I've written both the script and added the mine in the cfgAmmo, vehicles, mag etc... I'm now trying to make it work with Zeus interface, I've created the module and I'm able to spawn the mine, I wanted to hook my function using the "eventHandlers" class in the config. class myMine: ModuleMine_F { //removed for brevity _ammo = "myAmmo"; class EventHandlers { init = "systemChat 'init vehicle';"; }; }; But this seems to bug the module and the mine doesn't spawn. I tried to use the cfgAmmo EH: class myAmmo: ATMine_Range_Ammo { //removed for brevity class EventHandlers { init = "systemChat 'init ammo';"; }; }; But this one doesn't even fire when the mine is placed. Both are registered and visible in the Config Viewer. Is there a way to make a curator placed mine run a script on spawn? Thanks.

I solved this, I resorted to using the position of the module mixed with nearestObject in order to obtain the newly created mine and finish from there.

Apparently, I was overwriting the default EH for the module, I fixed this by doing: class EventHandlers:EventHandlers { class myMod { init = "systemChat 'init vehicle';"; } } and class ModuleMine_F: ModuleEmpty_F { class EventHandlers; }; Tough the script still doesn't run on the created object but on the module.

This script allows you to call a cruise missile on a target, in order to fire it, add a custom support and execute this file. To call accurately, use a laser designator, otherwise, the missile will "SNAP" on a nearby building/car/man. You'll find more details inside the sqf file. http://www.mediafire.com/file/ky9d722ii88c6if/Cruise_Missile.zip/file New version.

I'm trying to make a custom CAS Support, the problem is that I am not able to return the cursor position, I've tried both cursorTarget and cursorObject, but when I am not facing a target it return object nul, if I get the position of where I am facing it returns [0,0,0], is there a way to return the position of the cursor?

Is there a way to create a bomb and make it home a laser target? Just wanted to know if there's a function for that. Thanks.

I'm trying to make a blackfish orbit an area while staying at a low speed, I tried with both limitspeed and forcespeed but the blackfish isn't slowing, I tried with other vehicles and it does work, so, my question is, can you limit loiter speed?

heli_0 limitSpeed 60; heli_0 flyInHeight 130; //_i = 0; _dirS = 0; for [{_i=0}, {_i<12}, {_i=_i+1}] do { _dirS = _dirS + 30; _idealPos = tgtCenter getRelPos [350, _dirS]; group driver heli_0 addWaypoint [_idealPos, 0, _i]; } My solution was creating my own loiter script

Yes, take a look at my showcase mission, it's inside the description.ext, anyway, I'll leave it here. "[] spawn fnc_CruiseMissile" To avoid spamming, it's a bit more complicated if you use triggers.

http://www.mediafire.com/file/ky9d722ii88c6if/Cruise_Missile.zip/file A new version, this also has a showcase mission inside.

Thanks to everyone for the feedback, I will release a new version soon!

Cruise missile by Bohemia requires you to lock with a laser, then you have to switch to the VLS, lock and fire, I created my version because I wanted a quick way of calling a strike.

mines = ["ATMine_Range_Ammo","APERSMine_Range_Ammo","APERSBoundingMine_Range_Ammo","SLAMDirectionalMine_Wire_Ammo","APERSTripMine_Wire_Ammo","ClaymoreDirectionalMine_Remote_Ammo","SatchelCharge_Remote_Ammo","DemoCharge_Remote_Ammo"]; player addEventHandler ["Fired", { params ["_unit", "_weapon", "_muzzle", "_mode", "_ammo", "_magazine", "_projectile", "_gunner"]; if (_ammo in mines) then { hint "Player placed a mine"; }; }];

I want to create a mission where you can place mines only after you've completed a task, I know I can add the mines to the player inventory, but is there an EH that triggers when a mine is placed? I've seen in "Resist" campaign he placed dozens of triggers to check if there was a mine, but it won't work for me.

I got it, I was using "_weapon" instead I had to use _ammo.

I created an FSM, but it's a mess, is there a way to snap states and conditions in column and rows to make it cleaner?

Found it! Used the "grid" in Page setup
