Help with unit formations

[apptox]

Good afternoon. I'm writing to you regarding the creation of formations from units in Factorio, as I found you by searching. Can you please help me with this?
P.S. sorry for missclick, I'm don't want closing that issue.

If you're asking about how to create formations when using the RoboTank mod, please explain the issue you are having; what are you trying to do, and what is happening instead?

If you want to ask something about unit formations in Factorio generally, I don't know much about that, since RoboTank's squad formation logic is entirely specific to that mod; it does not use any general "formation" API for example. You could try asking at https://gaming.stackexchange.com/ instead.

How do it running in that mod? Because I'm don't see that feature in other mods, as I'm say you.

I think you are asking how RoboTank's squad formation works. For each player that has a commander vehicle, each RoboTank unit remembers where it was in relation to its commander when both came into existence (whichever was placed second). For example, one RoboTank might remember being 3 units to the right and 5 units ahead of its commander, relative to whatever direction the commander was facing. Then, each unit tries to stay in formation by first computing where it should be based on where the commander currently is and which direction it is facing, then driving toward that location while attempting to avoid colliding with other units.

The mod's source code (control.lua) is fairly heavily commented, so I suggest looking there for more details.
