SubFormation System


A little addon/script that gives you the possibility to keep teams in an advance/flank/stay back capability with their own formation.

Select squadmembers and order them to move somewhere with the middle mouse button. Keep the button pressed for more then 0.4 seconds.
You will get a Hint if the unit remains in formation or holds at the expected position.

Let me explain more detailed what I want to achieve:
You have many AI members (for example 20) and are a teamleader.
You want some members (for example 2, 8, 15) flank right.

How it is in vanilla:
You order them through the advanced movement menu.

what happens?
They will get an offset from you, but they will keep the formation. The more units you have and the more distance they have between each other, the more the effect is visible.
The AI that still follows you, won't stick together.

For me it was especially distracting when I made the AI capable to treat each other medically with AGM.
They had the capability to help each other when they were closer then 5meters, without me interventing. More then 5m distance and I had to give them the order to move there to help.
When I used the flank and advance options, and they got under fire, they weren't able to help eachother, even when I wanted to see them as one subtroop.

How it is with this addon:
You order them to moveTo where you want them to be, and keep the middleMouseButton pressed for more then 0.4sec.

what happens?
Normally they would hold that position. If you kept the middleMouseButton pressed for more then 0.4sec. they will move if you move.
The selected team will stick together (Attention, I noticed also that higher squadnumbers will still have larger distances to each other, but not as large as without this script).
The soldiers that follow you, will stick together, closing the gaps.

Extract into the ArmA 3 Directory, by default this is located in:
32-Bit - C:\Program Files\Steam/Steamapps\Common\ArmA 3\
64-Bit - C:\Program Files (x86)\Steam/Steamapps\Common\ArmA 3\
After extraction it should look like this:
Steam\Steamapps\Common\ArmA 3\@your_mod_folder_name\addons\

You can also use the "Arma 3 Alpha" folder in your "My Documents" folder. Your folder setup could than look like for example this:
mydocuments\Arma3 Alpha\@your_mod_folder_name1\addons\
mydocuments\Arma3 Alpha\@your_mod_folder_name2\addons\
mydocuments\Arma3 Alpha\@your_mod_folder_name2\addons\

When present place the "userconfig" folder into your game install folder, usually:
"C:\Program Files (x86)\Steam\steamapps\common\Arma 3".
You may already have "userconfig" folder from other addons and/or mods in which case it is safe to merge the contents from this archive.

You'll also need to add a Launch Parameter to Steam, in order to do so right-click on ArmA 3 Alpha and click Properties and then Set Launch Options. In the window that opens enter in -mod=@your_mod_folder_name
For using multiple mods you would then do so like this:

You can also use -nosplash to get rid of the splash art and intro videos.

And of course you can also enable and disable community made addons and mods through the in-game Options Expansions menu if you do not want to mess with startup parameters!

When the above information still does not provide you with enough to learn how to install custom addons and mods you can always ask in our Guide On Installing Mods.

Known issues:
Problems I had:
Sometimes, if you give the orders, they won't move or only the formation leader moves to the expectedPosition until you move a little bit. This seems to be a timing problem I don't fully understand yet.
Like Igitur, also in this example the units will have the waiting status. The units need this state, otherwhise they won't react to the doMove commands and the whole system won't work .

Problems that will come:
Other systems that order AIs to do something, might be affected.
If ACE adds AI Treatments, there will be some priority problems with the doMove/doStop orders which the system will use (that's how it was done in AGM and I won't know any other possibility).
If nobody works on it, I will try to do it and in that case, I would try to make also some kind of priority management for future mods.
Edit: I have seen ACE won't use scripts for AI in order not to cause problems with AI mods.

It's similar to Igiturs Custom Formation script. But it doesn't change AI Behavior regarding safemode!
Other differences are, that you can order multiple units at the same time and the AI will stay also in relation to the formationDirection.
Also I used more appends/deleteAt and no eval, which should harm less performance (at least on my old machine I didn't notice anything even with Igiturs script)
I'd like to thank Igitur for his script, I found his work when I had trouble with my system at the first steps and saved me a lot of time! ( )

Also if someone is capable to work with FSMs, I'd have some questions:
Would it be possible to achieve what I did, with an FSM?
I guess yes, but would it be possible to inherit from the base FSM?
Or would I have to rebuild all the functionality of the AI and then add my conditions and commands in order to have something useful?

Please let me know how you like the idea, realisation and what other features regarding AI you'd like.
I'd really appreciate your feedback and support!
I am no way experienced and always enjoy to see how others would solve the problems.
Will I resolve reported problems?
Maybe, but because of lack of talent/intelligence/experience I might not be able to do it.
Also because of my old systems I can't do any multiplayer tests but there should be no locality problems as the script is only used on your group and only if you are the teamleader (in which case they are local to you - exclusive ai which sits in vehicles with drivers of external localities, but then they even won't be needed).
