spawn vehicles at random distance from marker

[hogmason 2]

ive got this code that spawn my AA but im stuck on trying to get them to spawn around the map and not on the center

of my spawn marker.

Ive tried implementing in hundreds of ways something like this

_aadis = [200,500,1000,2000,3000,4000,5000] call BIS_fnc_selectRandom;

but i cant seem to get that to work in the code

this is my code any ideas how i can get the above code to work in the following code to let the aa spawn at random distances

       _grp = createGroup east;
           _aapod = createVehicle ["Igla_AA_pod_East", getmarkerpos "center", [], 0, "NONE"]; 
           _aapod setDir 290;
           _dir =  290;			
           _aapod addEventHandler["killed", { (_this select 0) spawn AALoop; }];

	    _gunner = _grp createUnit ["RU_Soldier_Crew", [0,0,1], [], 0, "CAN_COLLIDE"];
           _gunner assignAsGunner _aapod;
           _gunner moveInGunner _aapod;

i just tried this still no luck

       _grp = createGroup east;
           //_aapod = createVehicle ["Igla_AA_pod_East", getmarkerpos "center", [], 0, "NONE"]; 
	    _distances = [5,10,35,50,65,80,90] call BIS_fnc_selectRandom;
        _ang = random 360;  
        _dis = _distances; 
        _dx = sin(_ang)*_dis; 
        _dy = cos(_ang)*_dis; 
		_aapod = createVehicle ["Igla_AA_pod_East", [((getmarkerpos "center") select 0) + _dx, ((getmarkerpos "center") select 1) + _dy, 0], [], 0, "NONE"];

any ideas guys

[panther42 52]

I'll take a stab, even though I can't test right now.

The createVehicle array you are using allows for radius from the center of the given position, in which case you are using 0.

What would happen if you did this:

_aadis = [200,500,1000,2000,3000,4000,5000] call BIS_fnc_selectRandom;

_aapod = createVehicle ["Igla_AA_pod_East", getmarkerpos "center", [], _aadis, "NONE"];

See this post for reason why second example you gave does not work:

Tajin's explanation

Are you using the -showScriptErrors start up parameter?

[kylania 568]

Use shk_pos.

[panther42 52]

Good answer!

And I believe you have one of the more helpful posts within that thread...

kylania's explanation of shk_pos

cheers guys,

So i done kylania's tip with shk_pos but still not working i think i done it wrong this is what i done highlighted in red

           [color="#FF0000"] 
             _aadis = [200,500,1000,2000,3000,4000,5000] call BIS_fnc_selectRandom;[/color]
      _aapod = createVehicle ["Igla_AA_pod_East", getmarkerpos "center", [], 0, "NONE"];
             _aapod setDir random 290;
             _dir = 290;	
		[color="#FF0000"]
             _aapod setVehicleInit "_pos = [getMarkerPos "center", _aadis, random 359, false, [0, 0]] call SHK_pos;"
             processInitCommands;			 [/color]
             _aapod addEventHandler["killed", { (_this select 0) spawn AALoop; }];

           _gunner = _grp createUnit ["RU_Soldier_Crew", [0,0,1], [], 0, "CAN_COLLIDE"];
           _gunner assignAsGunner _aapod;
           _gunner moveInGunner _aapod; 
    hint "aa spawned";

[kylania 568]

shk_pos simply returns a position, so you'd use it before and within the createVehicle command.

_aadis = [200,500,1000,2000,3000,4000,5000] call BIS_fnc_selectRandom;
_pos = [getMarkerPos "center", _aadis, random 359, false, [0, 0]] call SHK_pos;	      
_aapod = createVehicle ["Igla_AA_pod_East", _pos, [], 0, "NONE"];
_aapod setDir random 290;
_aapod addEventHandler["killed", { (_this select 0) spawn AALoop; }];

Though as panther said you can just do this as well:

_aadis = [200,500,1000,2000,3000,4000,5000] call BIS_fnc_selectRandom;
_aapod = createVehicle ["Igla_AA_pod_East", getMarkerPos "center", [], _aadis, "NONE"];
_aapod setDir random 290;
_aapod addEventHandler["killed", { (_this select 0) spawn AALoop; }];

Not sure you need the setDir since it's a turret though. :)

[hogmason 2]

thanks mate.

i tried this but it diddnt work

_aadis = [200,500,1000,2000,3000,4000,5000] call BIS_fnc_selectRandom;
_aapod = createVehicle ["Igla_AA_pod_East", getMarkerPos "center", [], _aadis, "NONE"];
_aapod setDir random 290;
_aapod addEventHandler["killed", { (_this select 0) spawn AALoop; }];

[twirly 11]

Try this mate... tested and working.

_centerpos = getmarkerpos "center";
_aadis = [200,500,1000,2000,3000,4000,5000] call BIS_fnc_selectRandom;
_aadir = random 360;
_aapos = [(_centerpos select 0) + sin(_aadir)*_aadis,(_centerpos select 1) + cos(_aadir)*_aadis];
_aapod = createVehicle ["Igla_AA_pod_East", _aapos, [], 0, "NONE"];
_aapod setdir (random 290);

...then add your eventhandler.

EDIT: To test. Do this.... replace...

_aadis = [200,500,1000,2000,3000,4000,5000] call BIS_fnc_selectRandom;

with

_aadis = [30] call BIS_fnc_selectRandom;

That way you should see the Igla spawn 30m from the "center" and know if it is working or not.

**Note** you are going to have problems with stuff spawning in water, on or in buildings etc.

Clarity

[hogmason 2]

thanks guys all those work perfectly after twirly's comment on issues with spawning in things i.s buildings / water i have decided maybe shk_pos be the best option.

But i have one last question

is there away to set a distance between each aa gun so they dont spawn next to each other i.e maybe check to see no other gun is within 1000m.

This is the codes that work from u guys

_aadis = [200,500,1000,2000,3000,4000,5000] call BIS_fnc_selectRandom;
_pos = [getMarkerPos "center", _aadis, random 359, false, [0, 0]] call SHK_pos;	      
_aapod = createVehicle ["Igla_AA_pod_East", _pos, [], 0, "NONE"];
_aapod setDir random 290;
_aapod addEventHandler["killed", { (_this select 0) spawn AALoop; }];

_centerpos = getmarkerpos "center";
_aadis = [200,500,1000,2000,3000,4000,5000] call BIS_fnc_selectRandom;
_aadir = random 360;
_aapos = [(_centerpos select 0) + sin(_aadir)*_aadis,(_centerpos select 1) + cos(_aadir)*_aadis];
_aapod = createVehicle ["Igla_AA_pod_East", _aapos, [], 0, "NONE"];
_aapod setdir (random 290); 

[hogmason 2]

Also why is the below code aa.sqf working but when i modify it for another code it doesnt

so i use this code

and it works in that whole script but then i change a few names and add it to this script and it doesnt work nothing spawns and no markers or hints appear.

p.s the men and vehicles do spawn but no the static (in red)

[panther42 52]

nevermind, double checked myself

damn it...squint won't start up:mad:

Ok, just a quick question.

When you spawn AALoop, it in turn spawns createAA.

createAA creates 11 AA with gunners. Each one has a "killed" eventHandler which spawns AALoop and in turn creates 11 more AA.

So if 1 of the 11 gets destroyed, you are left with 10, but spawn 11 more giving you 21, and so on...

Is this intended, or am I reading this incorrectly?

Edited September 14, 2012 by panther42

[hogmason 2]

no thats not intended lol ive got to // that out this is all still testing

[twirly 11]

Just taking a quick look it seems there's one "}" too many.

Not sure how you intended it to work and haven't tested. But the last few lines need checking.

Otherwise the code looks good.

[hogmason 2]

Thanks twirly ill check it out mate. Dont supose u know how i can space the aa guns out so they dont spawn near each other mate or even a command to get me underway. Thanks again mate ur always helpfull.

[hogmason 2]

checked everything even retyped it all everything seems to be fine identical to the working version but this just isnt working

Ruebe has a function which will do this. You can see it in this post:

RUBE_randomCirclePositions

In which you can define:

             - "objDistance" (scalar)
              - minimal distance to other/nearest objects
              - default = 1

            - "posDistance" (scalar)
              - minimal distance between returned positions
              - default = "objDistance" * 2

See here for more explanation:

Explanation

I just checked my own ruebe library collection, his latest RUBE_randomCirclePositions has several added optional parameters.

You can find it here:

rube-wip

Or I can post if you need.

cleaned up my post...it was a mess

[hogmason 2]

thanks panther i think i might be able to filter throught that to find how he sets the distance to spawn away from another object.. very helpfull mate.

Now i got the code working turns out my issue was this

if ([color="#FF0000"]debug[/color]) then {

now that works in my other code that gets loaded from the main init

but with my new code it gets loaded from inside another script and for some reason doesnt remember this from my main init.sqf

debug = paramsarray select 2;

so i had to change it to

if(_debug) then {

///==== and place this at the top of my code

_debug = true;

I know this is fixed but i really need to have my new code read the debug from if (debug) then { so i can have the debug option in my params

would any 1 know why this happens and how to fix the issue.

_debug is just a local variable for that script, only that specific script can actually see the variable unless you used the call command. While "debug" is a global variable, accessible from all scripts. Which means that all scripts can change the value of the variable debug.

It's possible that your scripts, or some addon changes the value of "debug" and thus it's not true anymore. It's really hard for us to know why the value is changed.

That's why you should always try to have a TAG in front of your global variables, e.g : HGM_debug, to avoid such conflicts.

perfect cuel thanks mate something i diddnt think off i changed it to HOG_debug now everything works great maybe a third party script i used was using debug ;)

so while we are on the subject of code 1 question

when u use

private [_staic, _aa, _whatever, _whatever2]

this just makes those names only matter on the said script yeah,

so i can use those names again on another script and it want effect them.

is that how it works.

[cuel 25]

Short answer, yes. Except you need to place the variables in quotation marks

private ["_static","_aa"];

This is not needed, but it's recommended.

Every _localVariable that you create only exist within the scope of its control structure. A short example is:

if (true) then {
 _myVar = "hello";
};
hint format ["%1",isNil "_myVar"];

_myVar will not exist outside the scope of that if-statement, unless it has been created earlier, or by using private ["_myVar"] at the top of the script.

This will also work:

_myVar = "";
if (true) then {
 _myVar = "hello";
};
hint format ["%1",isNil "_myVar"];
