I noticed by default the Flip Vehicle script only works on larger vehicles (which most of us use), requiring 2 people.
A simple look into the fnselfactions.sqf file can change it from 2 to 1 person needing to be near the vehicle.
look for this section:
// CURSOR TARGET VEHICLE if(_isVehicle) then { //flip vehicle small vehicles by your self && all other vehicles with help nearby if (!(canmove _cursorTarget) && (player distance _cursorTarget >= 2) && (count (crew _cursorTarget))== 0 && ((vectorUp _cursorTarget) select 2) < 0.5) then { _playersNear = {isPlayer _x} count (player nearEntities ["CAManBase", 6]); if(_isVehicletype || (_playersNear >= 2)) then { _player_flipveh = true; }; };
Where it says _playersNear>= 2, you will want to change that number to a 1.
Save!
PBO and upload to panel. Or change through FTP.
Now you can flip all vehicles without the help from another person. All ground vehicles and some tanks.
