Inside the cfgVehicle class:
...
class eventHandlers
{
fired = " ...";
};
what exactly do you need ?
The 'fired' EH returns a five elements array: the first (_this select 0) is
the shooter, the last (_this select 4) is the ammo type being fired,
the other elements are the weapon being fired and its muzzle modes.
This array can obviously be used inside the EH itself, that is:
fired = "if ((_this select 4) == ""psy_mcar_dummyTow"") then {deleteVehicle (nearestObject [_this select 0, _this select 4]); ...};";
this delete the bullet fired by the shooter if this happens to be "psy_mcar_dummyTow" type. Note the use of double quotes: they
are compulsory, otherwise OFP will return an error.
