They also disembark if the vehicle is in the air and is not upright (such as attaching a tank to a plane then doing rolls with the plane, tank crew will disembark)

Facing the issue . If the vehicle is not straight they also disembark.

Added alt syntax in 149541 https://community.bistudio.com/wiki/allowCrewInImmobile

Is it mandatory to use the Alternative Syntax in 2.10?

I have a mod that sets

allowCrewInImmobile true;

which works pre 2.10, but no longer works after 2.10 update.

Changing it to the alt syntax format made it work again.

@BIS_fnc_KK

I'm using a very simple mod that's basically just

class Extended_InitPost_EventHandlers {
  class AllVehicles {
    class CrewInImmobile { init = "(_this select 0) allowCrewInImmobile true;"; };
  };
};

It worked fine in 2.08, but after I updated to 2.10 it stopped working (crew will exit vehicles when wheels/tracks are destroyed).

Then I changed it to the alt syntax

class Extended_InitPost_EventHandlers {
  class AllVehicles {
    class CrewInImmobile { init = "(_this select 0) allowCrewInImmobile [true, true];"; };
  };
};

And it started working again.
I'm not sure what's wrong lol.
Thanks!

Could you give me quick repro?

@BIS_fnc_KK do you mind if I upload the mod's config.cpp here?

There seem to be two issues:

Issue 1

The old syntax does not seem to work despite isAllowedCrewInImmobile returning true:

_p = player getPos [20, getDir player];

_v = "B_LSV_01_armed_F" createVehicle _p;
createVehicleCrew _v;

_v spawn {
	sleep 1;
	
	_this allowCrewInImmobile true; // does not work
	//_this allowCrewInImmobile [true, false]; // works
	//_this allowCrewInImmobile [true, true]; // works
	
	
	sleep 0.1;
	systemChat str isAllowedCrewInImmobile _this;
	_this setHitPointDamage ["HitLFWheel", 1];
	_this setHitPointDamage ["HitLF2Wheel", 1]
};

Issue 2

Executing the allowCrewInImmobile too fast after vehicle creation:

_p = player getPos [20, getDir player];

_v = "B_LSV_01_armed_F" createVehicle _p;
createVehicleCrew _v;

// none of below works, executed too fast?
//_v spawn {_this allowCrewInImmobile true}; // does not work
//_v spawn {_this allowCrewInImmobile [true, false]}; // does not work
_v spawn {_this allowCrewInImmobile [true, true]}; // does not work

_v spawn {
	sleep 1;
	systemChat str isAllowedCrewInImmobile _this;
	_this setHitPointDamage ["HitLFWheel", 1];
	_this setHitPointDamage ["HitLF2Wheel", 1]
};

I'm running profiling branch.

@veteran29 I must have looked at it dozen of times and couldn't see it. A typo! Issue1 is sorted, gonna investigate issue 2

Ok issue 2 cannot repro with spawn or without it works as expected

@veteran29 thank you, kind sir

About issue 2 though, I copied your code and executed, but it works as expected (in latest release version)

Unable to reproduce issue 2 anymore too... weird.

Should be fixed in rev.149832
