SHK_pos

[mariodu62 5]

Hi, i need some help. I use the lattest ARMA 3 dev build.

I try : _WAG_POS01 = [getmarkerpos _WAG_MARKER01,[100,250],random 360,0,[1,250],Armored] call SHK_pos;

and : _WAG_POS01 = [getmarkerpos _WAG_MARKER01,[100,250],random 360,0,[1,250],(typeof Armored)] call SHK_pos;

Result : Error Undefined variable in expression: armored

I have the same problem if i use heli and car, APC, MRAP.

Any idea?

try with the name of the armored, use quote for the name

[shuko 59]

The script uses findEmptyPosition to find the empty space. The command takes vehicle type as a string. If you want to have space for a MRAP for example, then find out the vehicle type of it. One type of MRAP is called "O_MRAP_02_F", for example.

Thanks, no more explodings armored :)

Before we start: Great job!

But.. :) Any chance to get road positions on the marker variation of this awesome position script?

Also there seems to be a bug when calling the anchor, distance based variation with search for a road.

For example [player,[0,1],random 360,0,[1,100]] call SHK_pos; This goes ok.

But this [player,[0,1],random 360,0,[2,100]] call SHK_pos; leads to issues when the SHK_POS cannot find a road within the given 100 or first given 1 (paramter 2).

Probably, when I get enough time/motivation.

Are you sure the position retrieved with parameter value 1 is actually a road position? Since with value 1, if none found, it will return a random position as a fail safe.

No, i just wanted to help you isolate the issue. The moment the value 2 is used and within the limites of range a road is not found, then the script goes into errors (i have show script errors on in Arma 3). It does however continue as normal.

And yes, time and motivation are closely related ;)

[spirit6 51]

Hey.

I created the functionality to produce road waypoints myself (and a few other things i needed). If you like i can share it with you.

That seems very lovely. It would be great if you don't mind sharing it.

[spirit6 51]

Changes:

/* Select a random position from an area defined by a marker.

In: [marker,MaxPos,PositionSurface,MinDisPos,debug,blacklist,emptySpace]

Out: position Array

*/

0) Marker (the marker we need position in)

1) MaxPos (Maximum number of positions we need, it auto iterates for you)

2) PositionSurface (0,1,2,3 - Land, any, water, road)

3) MinDisPos (The minimum distance between the found positions in the array)

4) Debug (show me where you make that positions if set to true)

5) blacklist (the blacklist marker name or array of)

6) emptyspace (the thingy that needs the space in the pos)

It will now return an array of positions instead of just one Pos.

The MaxPos iterations are on 10% fail or max 20 fails. So searching 20.000 water positions on land wont drag the server down. (might need work)

If non found the return value will be [].

Yes the code needs more tweaking and be more neat. Its functional but i am still in WIP to get this code fit into my own needs. Nice work on this thing by the way mate.

Anyway, hera ya go. http://speedy.sh/8AcmJ/shk-pos-getposmarker.sqf

Thank you

Hey Shuko, you have any plans of releasing a new version of this? I'm using this in conjunction with your moveObjects script to move players and objectives (objects/markers/etc) to random points on a map. For the most part it works really well, but it'll occasionally pick a bad location and even stick players inside of rocks (often along the shoreline).

[das attorney 858]

@Meatball, you could filter the results to check for nearestObjects (unclassed) and filter for anything with ": r_" in the string. (without the quotes).

[meatball 25]

Yeah, I was just thinking it might be easier to throw some sort of 'isFlatEmpty' check in there as well, but it really chokes the process from what I can tell.

Does that happen even with using the 5th parameters?

[meatball 25]

Yes it does. I've tried setting the 5th parameter to a vehicle (big Green transport chopper), or even just a set distance, 200-300 and it will still do it. My guess is that what's happening is the original check is finding a water location, so it's pulling in and then finding the closest location which is the shore.

Basically what I'm doing is setting up an area of units (objects/players) I want to move and throwing in two small objects (pencils). I run the SHK_pos based off an objects I have at the center of Altis, then move the first pencil there. Then I use your move objects to move everything else based off the two pencils :) Not the cleanest, but it works pretty well. Maybe the pencils are so small the setPos on them doesn't care that the 'position' it found is under a rock and throws it there, then moveObjects throws everything around it.

Here's the actual script that runs. It moves nine different batches of objects to random locations across Altis. Some include just objects, others move triggeers and markers as well.

I was digging into the script a bit more and it seems like shk_pos_fnc_getpos.sqf is the key.

//  In: [position,distance,direction]
// Out: position
private ["_pos","_dst","_dir","_orgX","_orgY","_posX","_posY"];
_pos = _this select 0;
_dst = _this select 1;
_dir = _this select 2;

_orgX = _pos select 0;
_orgY = _pos select 1;
_posX = _orgX + (_dst * sin _dir);
_posY = _orgY + (_dst * cos _dir);

[_posX,_posY,0]

Shouldn't I be able to throw an isFlatEmpty check into that somehow so it'll keep checking till it finds a location that's somewhat flat/empty?

[shuko 59]

Not really, because it's the object mover that moves the stuff? Or is the unit/object inside a rock always the anchor/middle one?

Edit:

If you can bother trying if this works, at all. I didn't test it. Change foreacg at the end of the moveObject.sqf

{
 _xPos = getpos _x;
 _dir = ((_xPos select 0) - (_aPos select 0)) atan2 ((_xPos select 1) - (_aPos select 1));
 _dir = _dir + _dAdj;
 _dst = _aPos distance _xPos;
 if (!isnil "_fDir") then {_x setdir _fDir};

 _xPos = [((_dPos select 0) + (_dst * sin _dir)),
           ((_dPos select 1) + (_dst * cos _dir)),
           0];

 _endPos =+ _xPos;
 _endPos set [2,20];
 for "_i" from 0.25 to 20 step 0.25 do {
   _endPos set [2,_i];
   if (!(lineIntersects [ATLToASL _xPos, ATLToASL _endPos])) exitWith {};
 };

 _x setposATL _endPos;
} foreach _objects;

I can't remember for sure if it is the isFlatEmpty check that basically doesn't find much as it is probably way too restrictive. So, you'll find almost no suitable locations when there really are some. It is mostly why people use their own methods.

[CommuneCode 10]

I am having an issue with this script, it is not working when I preprocess it in my init.sqf, it is loading, but not linking to the marker I set to the pos variable, I think it may be that I am not putting the pos variable with the parameters and stuff in the right place, my code is on GitHub, it's for ArmA 2, but you posted on the other post that it was the same script, cheers!

[CommuneCode 10]

Bump.

[oktyabr 12]

I basically want to find a random location a minimum distance from any buildings or roads (500m) to place a 200m x 200m marker for helicopter crash locations, etc. Is there an easy way to do this?

[na_palm 19]

for buildings you could use BIS_fnc_findSavePosition or so... don't think it considers roads.

forget what i wrote...

Anyone able to get Invade and Annex working on Chernarus, I am stuck, I get the error mapSize param is not defined for 'Chernarus'

Any ideas on how to fix? , am using latest version of this SHK_pos to get some units spawned in but radio towers will not.
