setGroupID don't change names in the MP lobby. They keep their original alpha 1-1 etc group names until the mission starts.
Update:
If this method is not possible (ticket 0012213), then some kind of alternative method could give the same outcome. Example: a file in the mission PBO where you define the group names manually. Anything. OCD.
This would help describing the group as a whole (example: Motorized infantry platoon 1, squad B). Much better than putting everything into the description box (in previous example I'd use "Automatic rifleman, fireteam 2" instead of what I have to use now, "Motorized infantry platoon 1, squad B - Automatic rifleman, fireteam 2".
Summary: It would make the lobby look cleaner and it would be much easier to find the right slot.
Yeah, I assume, the game only reads the mission.sqm for the slots and descriptions while ignoring init etc.
Would it be possible to add a new text field in the editor next to the desciption, in which you would be able to set the squad/callsign? That way there would be a clear place/variable for the game to read without having to go into init field.
Again, even if it was done via a text box next to the description, MP would need, I quote "a more serious revision".
No need to sound so dramatic. Add box to editor, save a line to mission.sqm then just make the parser read the new line, when it's already retrieving slots and descriptions. However, the system likely being same as in OFP 13 years ago. So, the code is probably a huge ball of crap nobody wants to touch.
I do so want this very much. It's quite ridiculous that this hasn't been addressed yet. It's seemingly trivial and would save so much headache to multiplayer pre-game slotting.
So there is absolutely no way to change the group names in the MP lobby yet? :/
For a military simulation, this should really be addressed somehow.
A3Ru how was it done`? Did they manually change something in mission.Sqm ?
Hope this gets a propper implementation soon.
