Please add a new Event Handler that triggers when a vehicle breaks the sound barrier (specifically when soundSetSonicBoom[]={}; from CfgVehicles hits).

I want to spawn the vanilla shock cone model "\a3\data_f_jets\particleeffects\shockcone.p3d" exactly when the plane goes supersonic and not use each frame or looping. This will also be useful for other purposes.

Usage examples:

_plane addEventHandler ["SonicBoom", { params ["_vehicle", "_isSupersonic"]; /* do something */ }];

_plane addEventHandler
[
	"SonicBoom",
	{
		params ["_vehicle", "_isSupersonic"];

		if (_isSupersonic) then
		{
			private _cone = createSimpleObject ["\a3\data_f_jets\particleeffects\shockcone.p3d", getPosASL _vehicle];
			_cone attachTo [_vehicle, [0, -4, 0]];
			_cone setVectorDirAndUp [[0, -1, 0], [0, 0, 1]];
			[_cone] spawn
			{
				sleep 1;
				deleteVehicle _this;
			};
		};
	};
];
