Need help scripting helicopter DoMove's over 3000m?

Question

I know how to create a local marker, at a
given _pos.  But I do not know how to define
_pos.  This is what I need...

.sqs format only.
(1) check if (_Heli distance _Obj1) > 3000
(2)   if true, create a local marker 2,500m from the current pos of _Heli towards _Obj1
(3)   _pos = getmarkerpos (local marker)
(4)   #SrtLoop _Heli domove _pos; (_Heli distance (local marker) < 200)
(5)   if true, delete local marker and perform steps (1) through (4)

To create a localmarker here is the code...

Code: [Select]

  deleteMarkerLocal "Wpt";
  createMarkerLocal ["Wpt",_pos];
  "Wpt" setMarkerShapeLocal "ICON";
  "Wpt" setMarkerColorLocal "ColorGreen";
  "Wpt" setMarkerTypeLocal "DOT";
  "Wpt" setMarkerSizeLocal[0.5,0.5];
  "Wpt" setMarkerTextLocal "Wpt";

Program execution will not exit #StepLoop until _Heli distance _Obj1 < 3000

Code fragment of E1EvacRTB.sqs
;Execute StepLoop until distance to _Obj1 < 3000

#StepLoop


  ;Need code here to cause _Heli to fly towards _Obj1
  ;until condition is met, at which time the rest of
  ;the script will take charge to ensure _Heli lands
  ;at base.


  ;Error checking routine has already been added along
  ;with exit-loop conditions.
  ? ((!(_Pilot in _Heli))||(!(alive _Heli))||(!(alive _Pilot))||(!(canmove _Heli))): goto "Cont";
  Hint Format["Dist > %1 ETA %2",_CDist,(_Heli distance _Obj1)];
  ? ((_Heli distance _Obj1) < 3000): goto "Restart1";

goto "StepLoop";

I moved this here as it looks more like a scripting problem, and sqs says "OFP" to me.

Secondly, while I understand the satisfaction one can get from scripting something yourself, this problem has already been solved by Mandoble, for OFP, ArmA and for Arma2.

Reinventing the wheel can be fun, but it does waste a lot of time.

Hi, sorry if I put it in the wrong place...  But, Arma 1 does support .sqs, and I no longer have Operation Flashpoint installed.  This was part of a project created for Arma, using Arma, and while I am slowly in the process of converting as much of my sqs into sqf format, I havn't quite reached a level of expertise, such as
Mando...  In fact, I've been trying to contact him, regarding his solution, but I fear I may not hear from
him, and I must come up with whatever workaround I can.  His work is awesome, but he doesn't really
explain much in terms of how to break down is SOLUTION so that it can be used by people such as myself
looking for answers to old problems.

This code is not a port from Flashpoint either.

What exactly is the problem? Your thread title fails to indicate whether you are submitting a resource or asking a question?

Is it just one question?

But I do not know how to define
_pos.

Or are there other concerns?
To grab the coordinates of a position, use the getpos command with the global variable(name) of the marker or object. Or just execute a distance check on that variable. It doesn't matter if the variable is local or global, so long as you access it correctly.

If this is a CAS script, a startpos marker(or even assigning a local variable to the starting pos of the helo within your looping script will identify the RTB pos. You can then use onmapsingleclick for player interaction with the helo, or player pos, or waypoint pos, or create a new waypoint for the unit and helo and synch them.

To have that helo move toward the object/marker/player, use distance checks with domove getpos or move newpos(newpos = predefined coordinates). You can also use object id's nearest the pos to perform distance checks. The simplest way is to insert a game logig or marker and have the helo continually move to that object. Just setpos the object wherever you need it.

Sorry if this is not helpful
