Any chance we could get some improvements to the eventHandlers seatSwitched and seatSwitchedMan by supplying the positions and turrets like are available for GetInMan and GetOutMan events, rather than relying on assignedVehicleRole.
At the moment there is a lot of ambiguity between position names.
Place a unit for the player.
Place an empty Marshall apc.
In the players init write
player addEventHandler [ "GetInMan",{
params[ "_unit", "_pos", "_veh", "_tur" ];
( assignedVehicleRole _unit ) params[ "_asPos", "_asTur" ];
hint format["GetIn\n%1\n%2\n\nAssigned\n%3\n%4", _pos, _tur, _asPos, _asTur ];
}];
player addEventHandler [ "seatSwitchedMan",{
params[ "_unit" ];
( assignedVehicleRole _unit ) params[ "_asPos", "_asTur" ];
hint format["Switched\n%1\n%2", _asPos, _asTur ];
}];Run up to the apc and experiment with the commanders position both from getIn and seatSwitched.
Note the ambiguity between [ "Turret", [0,0] ] and [ "commander", [0,0] ]
