Is there any way to prematurely stop unitPlay without killing the animated unit?

[theregurgitator 10]

I am trying to make a mission with a sniper on a helicopter trying to take out a vehicle (using Firing From Vehicles) and I recorded the helicopter's movement so the mission could be played solo as the sniper. I have already figured out how to get the vehicle being chased to stop (using 'waitUntil {targetTruck getHit "<part>" > 0.2}' to detect if <part> was hit).

I was wondering if there was any particularly easy way to stop the unitPlay so I could seamlessly have the helicopter react to the vehicle being disabled.

Code so far:

_movementdata1 = //a good 1-2 minutes of positional data

_sequence1 = [sniperHelo, _movementdata1] spawn BIS_fnc_UnitPlay;

waitUntil {targetTruck getHit "motor" > 0.1} || {targetTruck getHit "fuel" > 0.4} || {targetTruck getHit "hull" > 0.5} || {targetTruck getHit "tire" > 0.1}; //still tweaking values here

hint "vehicle disabled"; //for testing
targetTruck setHit ["motor", 0.95];
targetTruck setHit ["fuel", 0.0];
targetTruck setHit ["hull", 0.6];
//code to make helicopter react would go here

I plan to release this mission on Steam Workshop when I get all the problems/gameplay flow worked out and the production value is high enough.

I have found a way to stop it, but it isn't "seamless":

sniperHelo setFuel 0; 
sleep 0.01;
sniperHelo setFuel 1;

This stops the helicopter where it is (stationary), and plays a bit of the engine failure/engine relight sound effects.

I did it ... mostly. This makes the vehicle hitch in place for a bit but does the hitching does not kill immersion or cinematic qualities. Here is my release version. All I ask is for users to keep the "by TheRegurgitator" part in and credit me for the code somewhere visible (in case you binarized the mission files or something).

// --- get vehicle out of unitPlay V1.1 --- by TheRegurgitator

//out of fuel method stops vehicle momentarily, but it retains its velocity when it is set back to _vel

//get velocity
_vel = velocity _vehicle;

//stop unitPlay
_vehicle setFuel 0;
sleep 0.001;
_vehicle setFuel 1;  // you can change this value to have it get the fuel from beforehand, but usually fuel is not an issue when using unitPlay

//set velocity back to previous
_vehicle setVelocity [
	(_vel select 0), 
	(_vel select 1), 
	(_vel select 2)
];

Ask me any questions you have about how to implement this.

If anybody finds a way to eliminate the "hitch" inherent in this, that would be awesome. Also, I have only tried this with the MH6, so I am not quite sure about land vehicles being able to use this. The setVelocity might phase the vehicle into the ground a bit, which might provoke ARMA PHYSICS^TM. Other helicopters should be fine.

Functions viewer in your editor is your friend, stop playback any time by:

_vehicle setvariable ["BIS_fnc_unitPlay_terminate",true];

Thanks, that's just what I needed!
