Heli TRULY stop when I want

[barbolani 198]

Hi!

Anybody of this gentlemen knows a way of stopping a heli in an accurate way, wherever you want?

I'm working on a dynamic AI controlled fastrope script, everything ok, except the heli stops (speed heli < 1) two or three hundereds of meters away.

I tried forcespeed, dostop, disableAI "MOVE" on the pilot when reaches a distance < 150 mts from the landing pos, and nothing. The AI has everything disableAI. The waypoint is CARELESS and LIMITED.

It does not respect my flyinheight too....

The main thing with this is the landpos is fine calculated not to be on the sea, but as the heli is doing weird things, sometimes it drops the units in water....

EDIT: It is not a matter of accurate stopping, cause the heli when it's close starts to deccelerate, but, after two seconds, accelerates again...

instant stop you want

this setVelocity [0,0,0];

uffffff

setvelocity would make it magically stop, even at low speed will be noticeable.... It is a possible workaround, but requires a ton of maths, isn't it? I mean, check the velocity, check if each element is more or less than zero, gradually change each element from original status to zero.... And the heli won't change it's "stance"....

EDIT:

or not?

Have you ever tried something like this?

_vel = velocity _vehicle;

_dir = direction _vehicle;

_speed = speed _vehicle;

while {_speed > 1} do

{

_vehicle setVelocity [

(_vel select 0) + (sin _dir * _speed - 1),

(_vel select 1) + (cos _dir * _speed - 1),

(_vel select 2)

];

sleep 0.5;

_dir = direction _vehicle;

_speed = speed _vehicle;

};

You can lerp/interpolate vectors, for example:

// Some parameters
private ["_object", "_slowdownTime"];
_object 		= [_this, 0, objNull, [objNull]] call BIS_fnc_param;
_slowdownTime 	= [_this, 1, 10, [0]] call BIS_fnc_param;

// Store initial time
private "_initialTime";
_initialTime = time;

while { time - _initialTime <= _slowdownTime } do {
	// The current and target vectors
	private ["_vectorCurrent", "_vectorTarget"];
	_vectorCurrent = velocity _object;
	_vectorTarget = [0,0,0];

	private ["_x", "_y", "_z"];
	_x = linearConversion [_initialTime, _initialTime + _slowdownTime, time, _vectorCurrent select 0, _vectorTarget select 0];
	_y = linearConversion [_initialTime, _initialTime + _slowdownTime, time, _vectorCurrent select 1, _vectorTarget select 1];
	_z = linearConversion [_initialTime, _initialTime + _slowdownTime, time, _vectorCurrent select 2, _vectorTarget select 2];

	// Lerp
	_object setVelocity [_x, _y, _z];

	// Delay
	sleep 0.01;
};

Not tested. :P

Damm, this is solved....

You know what? I HATE SETWAYPOINTBEHAVIOUR.... After some debugging I found that command, dont know why, is not working... A fine setBehaviour made the trick...

f**k.
