Usage

Handling flags are regular bit flags, there are 4 macros defined to help operating on them:

• FLAG_IS_ENABLED(flag_var, flag) - Checks if a certain flag is enabled in the flag_var variable
• FLAG_ENABLE(flag_var, flag) - Enables a flag in the flag_var variable
• FLAG_DISABLE(flag_var, flag) - Disables a flag in the flag_var variable
• FLAG_FLIP(flag_var, flag) - "Flips" the flag in the flag_var variable, if it was enabled it will be disabled and vice versa

Examples

// disable the annoying 'swinging' of the body in Sabre
new flags;
GetModelHandlingInt(475, HANDL_HANDLINGFLAGS, flags);
FLAG_DISABLE(flags, HFLAG_SWINGING_CHASSIS);
SetModelHandlingInt(475, HANDL_HANDLINGFLAGS, flags); // the value needs to be set, FLAG_DISABLE only modified the value

// enable the bluish halogen lights if the vehicle has the DOUBLE_EXHAUST model flag
new flags, vehicleid = GetPlayerVehicleID(playerid);
GetVehicleHandlingInt(vehicleid, HANDL_MODELFLAGS, flags);
if(FLAG_IS_ENABLED(flags, MFLAG_DOUBLE_EXHAUST))
{
    GetVehicleHandlingInt(vehicleid, HANDL_HANDLINGFLAGS, flags);
    FLAG_ENABLE(flags, HFLAG_HALOGEN_LIGHTS);
    SetVehicleHandlingInt(vehicleid, HANDL_HANDLINGFLAGS, flags);
}

Some flags might not work for players that had the vehicle streamed in until they re-stream it. That's because some flags, such as HFLAG_SWINGING_CHASSIS are set before the vehicle is actually created in-game.
