Description
Arma 3 Iron Dome mod
This mod allows vanilla launchers to intercept incoming ammunition (Shells, Rockets, Cruise missiles....).
It also adds a new launcher inspired by the Israeli Iron Dome.

You can customize many parameters by using the following function:
[launcher, distance, logic, [missile speed, guidance, N, aiming, time to max, delay], searchArray] spawn IRON_DOME37_fnc_handleDome;

TIPS
Some tips to optimize the launcher interception rates for your clips or missions:
  1. Place the artillery unit at least 1km from the target (ideally this should be 3km or more to let the system use its range to its maximum. (Iron dome has 3km, other systems on average 7 to 9km)
  2. Ideally the dome should be placed in the path of the rockets and not where they are targetting, this way you can use the range "twice".
  3. Swarm attacks are hard to counter even in real life, I tried my best to optimize this but don't expect an handful of domes stopping 10 grads or 10 mortars, if you want to try something like this, spread them out in such a way the shells don't impact all at one.
Customization
The parameters are the following:
  1. Launcher: The object name
  2. Distance: Distance at wich it will intercept
  3. logic: Logic used to pick targets: 0 - random, 1 - speed bias, 2 - threat bias
  4. missile speed: Missile maximum speed (Use values between 250 and 1000)
  5. Guidance: Guidance law: 0 - APN (best one), 1 - PN, 2 - LOS (worst one)
  6. N: Guidance gain, typical values between 3 and 5
  7. Aiming: If the launcher has to aim the target
  8. time to max: Missile speed increases linearly and reaches the max in said time
  9. delay: Delay between shots
  10. searchArray: Default: ["ShellBase","SubmunitionBase"], should cover most of the ammo
To use the custom function just place it in a launcher's init, ie:
[this, 7500, 2, [1100/3.6, 0, 4, true, 30, 3]] spawn IRON_DOME37_fnc_handleDome;
Should also work for modded units

By default Vanilla launchers are initialized with their values so you only need to run this if you want to change something.

Known issue: Sometimes the missiles will go slow after being launched when shells are inbound, this is due to the APN algorithm fighting the missile accelleration, solution is to add more speed to the missile or change the launcher location. This has hopefully been fixed, a better solution is also going to be developed soon.

Code can be found here:
https://github.com/Dankan37/Arma-3-Iron-Dome

LATEST UPDATES:
Added original siren, when a missile is detected, as a bonus it will also broadcast the siren across all "Loudspeaker" objects nearby (Class name: Land_Loudspeakers_F)
Improved the code to switch between APN and PN fixing the issue of missiles' guidance being saturated
The system will not intercept ammuniton fired within 300m from the launcher

Known bugs:
Multiple launchers each play his own siren
Some missiles don't work and get no guidance and just start floating (rare)
Actions not added on MP (fix found)
Launcher might struggle on dedicated servers (fix otw)

i've noticed the iron dome system, in the eden editor. Would go after friendly drones. Spesifically from the Western Sahara DLC. it's difficult to use it, alongside the drones in it

Another issue i find while playing in the eden editor. Is that the AA missile batteries used by BLUFOR and Independent would still target each other's artillery shells and missiles/rockets. Even if i were to set them as allies

Also aces most recent update broke the iron dome as it replaced it with its own missiles. Dunno if there is a config in ace to change this other then manually inputting the correct ammunition.

Add a feature to disable the siren as its very loud and annoying, and more importantly, it's bugged, as the siren doesn't stop playing even after the iron dome has been deleted, only ending after some time, the siren should stop playing the moment missiles are no longer being intercepted.

@Dankan37 After allot of testing I've concluded its ONLY when I place Blufor drones it causes the launchers to bug

I've been having the exact same issue is Lilduggyda'humble, in single player editor/zeus, the launchers keep firing into the sky at nothing with no trigger or cause. Worked fine about 2 weeks ago, not sure if its the mod or some kind of update to another mod thats caused an issue. cheers
