without a player being present

[steel fox]

What do you mean? the code works if the unit is spawned? Maybe just run it when the player spawns? Could be a case of the player object not being fully loaded before it spawns. https://community.bistudio.com/wiki/Event_Scripts#onPlayerRespawn.sqf

[tough abyss]

so the code i posted works in a debug console no issues

but when i put it in the event scripts, it does not work. My guess is because of the respawn screen, the player is technically loaded but hasn't selected a vehicle yet.

it despawns all my alive units during respawn menu, so you cant spawn in the vehicles until something loads them in.

i was hoping the local player init wouldn't load untill the player spawned in

[steel fox]

init runs upon joining

[tough abyss]

and i dont want to keep creating zeus modules for when the player respawns

so i cant use the on player respawn event script

brb thanks for your time

[steel fox]

Yes you can

Just check if old body is null

then you know it is a first spawn

[tough abyss]

true

[peak pond]

Hi, is a waypoint's onActivation script run on every machine, or just the machine of the group's owner?

[tough abyss]

I believe it is executed on every machine by default, same as with triggers

[peak pond]

Ok, thanks. I may put a safety check in the script just to be safe.

[tough abyss]

I think you have a good idea, i don't know what the issue is. anyway heres my code ```params ["_newUnit", "_oldUnit", "_respawn", "_respawnDelay"];

if (_oldUnit == objNull) then {
_logic = createGroup sideLogic;
_zeus = _logic createUnit ["ModuleCurator_F",[0,0,0],[],0,"NONE"];
_zeus setVariable ["Owner", ""];
_zeus setVariable ["Name", ""];
_zeus setVariable ["Addons", 2];
_zeus setVariable ["Forced", 0];
[_newUnit, _zeus] remoteExec ["assignCurator",2];
_zeus addCuratorEditableObjects [[_newUnit], true];
[_zeus, [-1, -2, 0]] call bis_fnc_setCuratorVisionModes;
_zeus addCuratorPoints 0.1;
};

it will work on debug console if i replace the variables with _newUnit = player

[jade acorn]

waitUntil {sleep 1; this in units group player };
_this call BIS_fnc_ambientAnim__terminate;```
in unit's init. Why is this *no bueno*? I'm trying to terminate the ambient animation when the unit joins players group - it joinSilents player in other place

[bitter jewel]

no sleeping or waiting in unit init

[jade acorn]

[] spawn { waitUntil {sleep 1; rfl_1 in units group player }; rfl_1 call BIS_fnc_ambientAnim__terminate;
};``` this one works but the unit looses all of its gear except uniform and weapon

it's for singleplayer btw

[bitter jewel]

that is a feature of BIS_fnc_ambientAnim

[jade acorn]

oh, so I have to give this stuff back to him through another script?

[bitter jewel]

give "ASIS" as third argument

[jade acorn]

I'll try

[bitter jewel]

https://community.bistudio.com/wiki/BIS_fnc_ambientAnim

equipmentLevel: String - the equipment level of the unit. Possible values:

NONE
LIGHT
MEDIUM
FULL
ASIS
RANDOM

[this, "SIT1", "ASIS"] call BIS_fnc_ambientAnim;

[jade acorn]

yes I must have missed that part, thank you so much

I tried to do the same thing with Ambient AI feature from 3den Enhanced that creates the same animation either as ambientAnim or ambientAnimCombat, but it's impossible to terminate any of those with the same spawn as above, manually setting combat behaviour also doesn't work, unless I'm wrong

[bitter jewel]

i haven't used that feature of 3den enhanced

but you should be able to terminate the animation with switchMove or playMoveNow

[proven charm]

why does the element order change when using createHashmapFromArray?

[little raptor]

Because it's a hashmap

aka unordered map

There's no order in hashmaps

If you need order you must use arrays

[proven charm]

ok but why does it shuffle the order?

[little raptor]

It doesn't "shuffle"
It depends on the hash

Hashmap uses the hash to map to a bucket

[warm hedge]

AKA the order means nothing for hashmap

[proven charm]

hmm

[pliant stream]

because the order it uses makes searching more efficient (that's the assumption anyway)

[little raptor]

Just google hashmap

Or hash table

[pliant stream]

it could preserve iteration order but that would make the table more complicated

you can do it yourself by storing your data in an array and using a key->index table instead

[proven charm]

I'm just curious why the order of elements changes

[little raptor]

Like I said just google it and you'll see

[pliant stream]

https://en.wikipedia.org/wiki/Hash_table

[proven charm]

thx for the link , I think I understand little better now

buckets and all, I think it's an optimization thing?

[little raptor]

?
A bucket is just an array element

(usually)

[pliant stream]

it's all part of the hash table algorithm. the nice thing about hash tables is that they provide average constant time access

in other words, on average the time needed to find an element stays the same even as you add more elements

though that is not entirely true in reality, and also depends on the quality of the hash

a bad hash reduces efficiency of the table. the worst possible hash which assigns all keys the same hash value produces linear access times

that is, with that worst possible hash, as you double the size of the table, the time required to find a key also doubles

[proven charm]

interesting stuff, thx guys 🙂

[lofty vine]

has anyone experienced issues with using keyhandler, in terms of activation without an actual keypress?

E.g: someone opens a menu without pressing Y.

or perhaps a key activating something its NOT supposed to?

E.g someone opens a menu by pressing P instead of the assigned key(Y).

[winter rose]

looking at https://community.bistudio.com/wiki/getMissionLayerEntities, it seems there is no command returning all layers, right?

[bitter jewel]

seems so

[copper raven]

https://community.bistudio.com/wiki/all3DENEntities

[winter rose]

aaaaaah, thanks 👍

any way to get layer name from its id? 😁

[copper raven]

try https://community.bistudio.com/wiki/get3DENAttribute "name"

[winter rose]

ouh smart! 👍

[winter rose]

Attributes are available only within the Eden Editor workspace. You cannot access them in scenario preview or exported scenario!
also, all3DENEntities doesn't return anything when the mission is launched 😔

ah well, not mandatory for what I want to do, I'll find a workaround.

[copper raven]

don't have arma installed to examine how all the indexing and stuff works, could help more otherwise 😄 hope you get it working

[proven charm]

interesting that with hashmaps you can delete element when doing foreach loop without breaking the loop

(skipping elements)

[copper raven]

yes because the keys are copied

[proven charm]

ok

[pliant stream]

can you loop over a map?

[proven charm]

hashmap yes

[pliant stream]

{ } foreach _map ?

[proven charm]

yeah

https://community.bistudio.com/wiki/forEach

[pliant stream]

are you sure deleting works? seems a bit sus

[tough abyss]

Makes sense if you're only deleting the element and not the key as a whole

[proven charm]

this is what I used to test: ```
_hm = createHashmapFromArray [["test1",7],["test2",5],["test3",2]];

systemchat format ["==== %1 ====", _hm];

{

systemchat format ["%1 => %2", _x, _y];

if(_y == 2 || _y == 5) then
{
systemchat "deleting...";
_hm deleteAt _x;
};

} foreach _hm;

[pliant stream]

this test is not good enough

[proven charm]

how so?

[tough abyss]

Makes sense to me

no reason it'd be trying to iterate over a hashmap like an array, it'd just be performing key lookups

so deleting a key shouldn't break anything

[pliant stream]

that's not how any of this works

[tough abyss]

That's exactly how a hashmap works

[pliant stream]

that's how lookup works

by doing a lookup

you can't iterate by doing lookups

[tough abyss]

A foreach does not iterate over a hashmap in the same way one iterates over an array.

Is my point.

So deleting arbitrary elements during iteration shouldn't break anything

[pliant stream]

you have no way of knowing that

[tough abyss]

???

[pliant stream]

first of all you'd have to know the algorithm they use

[still forum]

You can't

[pliant stream]

i assume it's the same naive array of arrays as it is in A2

[still forum]

Key and value are one element

[tough abyss]

Yeah I meant value not element

[still forum]

It does.

[tough abyss]

mixup in wording

[still forum]

But it does.

[pliant stream]

it doesn't have to

[tough abyss]

I've never seen it break anything

¯_(ツ)_/¯

[still forum]

A hashtable is just multiple arrays.

[pliant stream]

usually it's one array

it would work if you used unordered_map, though i know you're not

[still forum]

You are iterating through many arrays. Deleting elements will mess it up the same as it does with arrays

[tough abyss]

That's entirely implementation defined

I'm used to things like unordered_map and such

[still forum]

Yeah I'm telling you how it's implemented

[pliant stream]

implementation defined... 🙄

[tough abyss]

Fair enough, wasn't aware it was implemented that way and I've never seen it implemented that way

I stand fairly corrected

[still forum]

It's basically exactly how hashtable is described on Wikipedia i think

Pretty sure.. multiple arrays as the buckets

[pliant stream]

yeah array of arrays is the kindergarten algorithm

it's fairly naive though. most real world implementations use open addressing

[tough abyss]

The entire idea of arrays as buckets is a bit... yuck

Might as well not be using buckets at all if you're not using open addressing

[pliant stream]

you do know how unordered_map works right?

[tough abyss]

I know the gist of it

[pliant stream]

yeah well they use an array of linked list buckets

[tough abyss]

Right but I'm talking about literally just hashing raw arrays and calling them buckets

[pliant stream]

what?

[tough abyss]

As in how that'd be a stupid thing to do

[pliant stream]

yeah sounds that way. did someone do that?

[tough abyss]

It has been done

and it's as bad as it sounds

[pliant stream]

i have no idea what you even mean

[proven charm]

so my test code is not supposed to work... 🙄

[tough abyss]

I must be wording it poorly

[winter rose]

as in, it might break
an item reorder may happen, from what I understand

[tough abyss]

what I'm saying is it'd be a very naive and stupid decision to use arrays as "buckets" instead of a linked list structure

[proven charm]

ok

[tough abyss]

as in literally just throwing arrays into a hashmap and pretending that it's anywhere close to actual buckets

[pliant stream]

wait you're saying linked list better than array?

why is that?

[tough abyss]

...?

I thought we'd already established that's how it's usually done

don't think I need to explain why

[winter rose]

[still forum]

[winter rose]

« They say of the Acropolis where the Parthenon is… »

[pliant stream]

do you know why unordered_map is implemented that way?

[tough abyss]

I assume it's because of literally everything that makes buckets a good idea in the first place?

[pliant stream]

well you assume wrong

it's because of the iterator stability guarantees imposed by the standard, and most of the C++ community considers unordered_map largely worthless because of it

[tough abyss]

Well I've been around the C++ community and I've never heard this lol

Nor has any education I've received ever talked about that

[pliant stream]

well it's entirely a performance issue. i guess it depends on the circles you hang around whether or not it'll come up

[tough abyss]

I know the standard enforces a lot of... unnecessary performance overhead in areas

but I don't really see a noticeable performance problem w/ unordered_map hashmaps in any usage of them I've done

[pliant stream]

well there's plenty of literature on the subject out there

plenty of benchmarks too

[tough abyss]

Are we talking significant performance decreases on a macro scale or microoptimization?

Cos I'd say it's quite a different story if it only applies when trying to scale a massive application for instance

[pliant stream]

the scale of the problem depends on how heavily your workload depends on the hash table

[tough abyss]

Well yeah

I mean moreso in terms of actual complexity

is this something that the average developer should be seriously considering avoiding

[pliant stream]

algorithmic complexity?

code complexity?

[tough abyss]

Yes

[pliant stream]

it's a hash table, it's average O(1) either way

we're talking about constant factors

[tough abyss]

Fair enough, though I know the average can sway due to implementation factors

Moreso what I'm getting at is

Is this a problem only someone writing code for a microcontroller should be worried about or something more universally applicable?

What's the scale of the performance difference

I'll have to look into the literature on it

[pliant stream]

https://martin.ankerl.com/2019/04/01/hashmap-benchmarks-01-overview/

well you don't have to worry about it

[tough abyss]

Wow that certainly grows at scale doesn't it

Interesting, I was not aware, thanks for informing me

[proven charm]

would this code work for deleting elements? ```
_hm = createHashmapFromArray [["test1",7],["test2",5],["test3",2]];

for "_i" from (count _hm - 1) to 0 step -1 do
{
_keys = keys _hm;
_k = _keys # _i;
_v = _hm get _k;

systemchat format ["%1 => %2", _k, _v];

if(_v == 2) then
{
systemchat "deleting...";
_hm deleteAt _k;
};

};

[pliant stream]

no

don't delete while you iterate

[proven charm]

hmmm

[pliant stream]

push all the keys to be deleted into an array and do another loop to delete them all afterwards

[proven charm]

ok

what if I use + copy? ```
_hm = createHashmapFromArray [["test1",7],["test2",5],["test3",2]];

{

systemchat format ["%1 => %2", _x, _y];

if(_y == 2) then
{
systemchat "deleting...";
_hm deleteAt _x;
};

} foreach +_hm;

[pliant stream]

that's fine

[proven charm]

ok thx 🙂

[still forum]

I hope you aren't doing lookups by value too often

[tough abyss]

Certainly doesn't invalidate the entire advantage of hashing

[proven charm]

not very often just checking if enough time has passed and deleting the element, this script doesn't run like every frame

[tough abyss]

Is there a particular reason you're testing this?

[still forum]

Ah it's a _y <... Check, instead of a ==?

[proven charm]

sorry test what? just trying to get this working without bugs 😉

[proven charm]

yes > check

[tough abyss]

Well it's just

I don't see what it could be being used for that would benefit from this implementation

[pliant stream]

sounds like you want a queue

[proven charm]

no problem, you have already helped me so thx for that

[still forum]

[distant oyster]

depends on the code that is used. but maybe it is because of different keyboard layouts, eg german has QWERTZ vs english QWERTY, so if you check for key_id == 123 (where 123 is the id for y) a german user would have to press z instead

[lofty vine]

Ahh, good point. I dont think it applies in the same way in our case as we are using numpad for it. Although it could be so. Thank you for pointing that out : D

[peak pond]

Is there some function to make an AI speak one of its preset dialogs? For example, in my paradrop script, I want to make a group leader say "Dismount!" over group channel.

[little raptor]

yes. groupRadio, or directSay

[peak pond]

Ah great, groupRadio looks like what I need, thanks.

[vapid drift]

Am I missing something simple here? The condition is apparently being ignored - the actions are visible all the time:

            player addAction [format["<t color='#FF0000'>Torch Nest</t> %1", _nest], {
                    params ["_target", "_caller", "_actionId", "_arguments"];
                    hint "Torching";
                    _caller removeAction _actionId;
                },
                [_nest], 6, true, true, "",
                "_this distance2D _target <= 3;"
            ];

[little raptor]

_this distance2D _target <= 3;
why not just change the action radius?

[vapid drift]

I can look at that as a viable option... but why is what I have not working

[little raptor]

also in this case _this and _target are the same thing

both are player

[vapid drift]

ah... yes, that would be it isn't it

[little raptor]

so distance is always 0

[vapid drift]

hmm I'm not sure the best way to go about this then. I could add the action to the "nest" and use this or modify the radius but that will require me looking directly at the object correct?

In this case, that doesn't really work because the nest is made of several objects... unless I were to add the action to everyone of them?

[winter rose]

then using _target distance _arguments and providing the nest as argument

[vapid drift]

Does the condition access the arguments? I tried: _target distance2D _arguments and _target distance2D (_arguments select 0) with no effect

[little raptor]

according to the wiki no:

condition: String - (Optional, default "true") Expression that must return true for the action to be shown. Special variables passed to the script code are:
    _target:
    _this: 
    _originalTarget: 

[vapid drift]

Yeah, I didn't think so - that's what I'm looking at also

[little raptor]

just add the action to the "nest"

[vapid drift]

well, like I said, I nest is made up of several different objects. Should I just add an action to each one to ensure the player can activate wherever they're looking?

I'm not sure what would be considered too taxing... looking at roughly 19 objects per nest

[winter rose]

use a global var and be done with it

[little raptor]

or use the player's var space

getVariable and setVariable

[vapid drift]

Regardless I'm looking at 19 possible objects the player could be looking at (could be realistically lowered to around 10) and multiple nests across the map... not sure how a single variable would help in this case

or am I missing something?

[little raptor]

you can use an array

[vapid drift]

Can you explain how that would work in this case? I currently have the nests in an array and listen for a thermite grenade... I was hoping to replace that with the action route

[winter rose]

not sure how a single variable would help in this case
distance to a position

[vapid drift]

If it was one nest sure but I'm talking about several nests

[winter rose]

player distance ([] call ST234_fnc_getNearestNestPosition)

[little raptor]

_nestID = 5; //nest index
player addAction ["blabla", {

}, ...., format ["_this distance2D allNests#%1 < 3", _nestID], ...]

[winter rose]

NestPositions = [/*...*/];
// ...

NestPositions findIf { player distance _x < 3 } != -1
```etc, etc

[vapid drift]

Ok... I don't think I'm fully tracking yet but I'm almost there! Thank you both

And there we go:

format["_this distance2D [%1, %2] <= 3;", (getPos _nest select 0), (getPos _nest select 1)]

lol is that worse?

[little raptor]

it'll do

[vapid drift]

I mean it works but I also don't want to get stuck with "good enough". Are the other options "better" or just different?

[little raptor]

well in general I don't think what you do is good. action conditions are evaluated every frame in unscheduled environment, and in this case it'll be evaluated all the time (since the action is added to the player). so if you have many of these "nests" it'll be bad, performance-wise.

[vapid drift]

Have any other clever solutions then? Should I just stick with adding actions to each the objects in the nest but changing the radius? At least that way they're not firing all the time

[glacial dust]

Hi, does someone have a recommendation for an animation of someone running and jumping from the ramp of a transport aircraft?

[vapid drift]

Well, I've gotta run... please ping me if you happen to think of something better

[little raptor]

how about one of those transport unload ones?

like the one for dismounting the back of a HEMMT

[glacial dust]

Maybe, I will take another look, thanks for the suggestion @little raptor

[tidal ferry]

Hey, I need help with being able to move an non-physics object slowly from A to B on dedicated multiplayer

Still having trouble with it, and not much clue where to start 😅

[little raptor]

p1 = [blabla];
p2 = [blablabla];
velo = [blabla];
spd = vectorMagnitude velo;
start = time;
duration = (p1 vectorDistance p2) / spd;
onEachFrame {
obj setVelocityTransformation 
[
    p1,
    p2,
    velo,
    velo,
    p1 vectorFromTo p2,
    p1 vectorFromTo p2,
    vectorUp obj,
    vectorUp obj,
    (time - start) / duration
];
}

[tidal ferry]

AMAZING. Thank you 🙏

[little raptor]

that's just for testing tho

[tidal ferry]

Promise I'll reverse-engineer it when I'm not in mission crunch so I can better understand it 😆

Of course

Any clue if it'll work in MP yet? I'll test it but just curious to know

[little raptor]

if you execute if locally yes

[tidal ferry]

Okay, sounds good

Thanks a ton

[little raptor]

here's a quick test case:

p1 = getPosASL player;
p2 = getPosASL player vectorAdd [0,100,100];
velo = [0,1,0];
spd = vectorMagnitude velo;
start = time;
duration = (p1 vectorDistance p2) / spd;
obj = player;
onEachFrame {
obj setVelocityTransformation 
[
    p1,
    p2,
    velo,
    velo,
    p1 vectorFromTo p2,
    p1 vectorFromTo p2,
    vectorUp obj,
    vectorUp obj,
    (time - start) / duration
];
}

just go in Eden, place a player, run the mission and execute

@tidal ferry also you need to add a termination condition ofc

[tidal ferry]

Will do

[little raptor]

if (time - start > duration) exitWith {onEachFrame ""}

[tidal ferry]

And yeah sounds good

[real tartan]

trying to locate some control idc from inventory display, but don't know if using right event handler

just put _x

[real tartan]

error: displayCtrl expecting number, control provided

[little raptor]

I said JUST _x

[tidal ferry]

Script works great on players, but not on the object I want to move, which doesn't have physics

[little raptor]

_x ctrlAddEventHandler ...

[little raptor]

it doesn't have anything to do with physics

units don't have physics either

[little raptor]

how are you trying to move the object?

[tidal ferry]

Replacing player with the varname of the object

[little raptor]

what's the object?

[real tartan]

player addEventHandler 
[
    "InventoryOpened", 
    {
        params ["_unit", "_container"];

        _unit spawn
        {
            waitUntil { !isNull ( findDisplay 602 ) };

            {
                _x ctrlAddEventHandler ["onMouseEnter", {
                    params ["_control"];
                    hint format ["%1", ctrlIDC _control];
                }];
            } 
            forEach ( allControls findDisplay 602 );
        };
    }
];

no hints

[tidal ferry]

It's a background object we have, virtually no physics

I can DM you about if if you'd like

WAIT

Nvm, think I got it

[little raptor]

you've put onMouseEnter

there's no such event handler

it's mouseEnter

read the wiki

[real tartan]

When using the event names listed here with the ctrlAddEventHandler, ctrlSetEventHandler, displayAddEventHandler or displaySetEventHandler commands, the prefix "on" in the event name must be removed (e.g. 'ButtonDown' instead of 'onButtonDown').
damn, I am blind

[tidal ferry]

Hey @little raptor, question

Does the above script need to be executed in the scheduled, or unscheduled environment?

I'm looking to stuff it into an execVM so I can use it with parameters and modify as needed, but it breaks in execvm

Could very well be my own inattentiveness but just wanted to ask

[little raptor]

it needs to be executed every frame

[tidal ferry]

I got that

But I mean, starting the onEachFrame from execVM

[little raptor]

as I said that's just for testing

you need to ditch onEachFrame

[tidal ferry]

Ah, gotcha

[little raptor]

and onEachFrame always executes every frame

doesn't matter where you execute it

it's an event handler

[little raptor]

and just to be clear, "for testing" doesn't mean "just change the variables and you're good to go"
it means you have to optimize it and fix stuff
what I wrote is naive and slow, and only for testing purposes

[tidal ferry]

I know, I'm just trying to understand it

It gets the basic functionality that I need done in SP, I'm just trying to figure out how to put it in an execVM so I can more easily use it

params ["_obj",["_velo",[100,0,0]]];

p1 = getPosASL _obj; 
p2 = getPosASL _obj vectorAdd [0,50,0]; 
//velo = [0,100,0]; 
spd = vectorMagnitude _velo; 
start = time; 



duration = (p1 vectorDistance p2) / spd; 





_execCode = { 
_obj setVelocityTransformation  
[ 
    p1, 
    p2, 
    _velo, 
    _velo, 
    p1 vectorFromTo p2, 
    p1 vectorFromTo p2, 
    vectorUp _obj, 
    vectorUp _obj, 
    (time - start) / duration 
]; 
};
addMissionEventHandler["EachFrame",_execCode];

I'm aware this is probably super sloppy, but I'm also super tired 😅

I'm pretty sure that the local variables aren't being passed to the event handler, which is why it's not firing right

[little raptor]

yes

[tidal ferry]

Hrm

Oh I'm a dolt

One sec

if (missionNamespace getVariable ["alreadyExecuted", false]) exitWith {};

      _dir, _dir, 
      [0,0,1], [0,0,1], 
      _interval
    ];
  } forEach movingObjs;

}];

there

it'll work with as many objects as you want

and the destination can change too

you just do:

_obj setVariable ["destination", _someASLPos];
_obj setVariable ["speed", _speedInMPS];
movingObjs pushBackUnique _obj;

o7

Amazing, I'll try this

[little raptor]

fixed the vector up

[tidal ferry]

Absolute legend

Thank you, you've saved me so many hours of trying to figure this out so far 😂

[little raptor]

remember that this should be executed only once (per client)
and you only need to add it to clients who have local objects they want to move

[little raptor]

this is the part that you execute for every object you want to move

[tidal ferry]

I've been trying it, but it just goess at like light speed faster than I can track it

No clue where it's going

[little raptor]

what do you put in for the variables and stuff?

[tidal ferry]

this setVariable ["speed", 0.01];```

It goes to light speed even when I put it super low

Orriginally I had it at like 50

[little raptor]

did you even make sure that the code executes once?

[tidal ferry]

I'm in singleplayer, and this is object init, so it shouldn't be duplicated

[little raptor]

I'm not talking about this

I'm talking about the event handler

I changed the code to make sure you don't mess it up

try it again

[tidal ferry]

OH, hurr durr, I missed that 😅

[tidal ferry]

And yet I still did

Sorry about that, thanks for your patience

[little raptor]

I changed it now

added a guard

[little raptor]

I just tested and it works fine

player setVariable ["destination", getPosASL player vectorAdd [0,100,100]]; 
player setVariable ["speed", 1];
movingObjs pushBackUnique player

change pushBack to pushBackUnique to be safe

[little raptor]

wait

wat?

are you executing that in init?

[tidal ferry]

Object init, yeah

[little raptor]

you should never put variable names in init

[tidal ferry]

Oh?

[little raptor]

they may not even exist

[tidal ferry]

Hrm

Aaaaaaa

Okay

Let me try it differently then

[little raptor]

in your case finalPos may not even exist

[tidal ferry]

...Very good point

So

It's somewhat working

So far, only problems are

1. The speed is way too fast, definitely not in M/S, more like KM/S, but that's an easy fix

2. The vector only moves vertically, think it's due to you putting the vectors as [0,0,1] in the setVelocityTransformation, though as we've proven, I am a dunce, so

[little raptor]

no it's not

[little raptor]

no

there's nothing wrong with my code

[tidal ferry]

Ah

Double checkinng now

[little raptor]

@tidal ferry

[little raptor]

literally this plus that EH code

[real tartan]

is there an opposite function to BIS_fnc_colorRGBAtoHTML ? ( HTML to RGB(A) )

[tidal ferry]

I keep trying it, and it literally just keeps going up into the air

How are you executing it? Just debug console?

[little raptor]

yes

no

[tidal ferry]

Yeah, I'm trying it from the debug console over and over again with almost the exact code

[little raptor]

exit the game

I mean the mission

you've probably broken it

[little raptor]

also make sure you've removed the old code

almost the exact code

try the exact code

[tidal ferry]

I have

[little raptor]

no change at all

[tidal ferry]

Give me like

5 seconds

[little raptor]

especially this one

even the tiniest change will break it

[tidal ferry]

Yeah, so, works perfectly fine on player unit

But it breaks on the object I'm trying to move

[little raptor]

is your mission vanilla?

[tidal ferry]

Nope

[little raptor]

what is the object?

give me the exact type and class and properties

[tidal ferry]

It's a very large, collissionless, physicsless, background prop inheriting from house_f

[little raptor]

have you disabled its simulation or something?

[tidal ferry]

Simulation is enabled

Essentially, when I fire the script

It basically moves at light speed to a position like

I'd say maybe 10-20km above the posASL I give it

As mentioned, it has no physics and basically just floats in the air

[little raptor]

as I mentioned, physics has nothing to do with this

you're moving the object with position and velocity

not physics

[tidal ferry]

Okay

Well, as mentioned it works for the player unit with the exact code you give me, but not with the object

Tbh I can probably just use a workaround with a dummy unit and attachto 😅

[little raptor]

what about this?

blablaObj setVariable ["destination", getPosASL player vectorAdd [0,100,100]]; 
blablaObj setVariable ["speed", 1];
movingObjs pushBackUnique blablaObj 

[tidal ferry]

Testing

Also, I'm going to replace player in that code with finalPos, an invis helipad I've got placed that I want it to go to

[little raptor]

no

don't

[tidal ferry]

Alrighty

[little raptor]

that's my point

[copper raven]

no

[tidal ferry]

And, to be absolutely clear, replace blablaObj with the variable name of the intended object, yes?

[little raptor]

yes

[tidal ferry]

Same result

Basically, spinning sideways in a rotation around a position roughtly like... 10km above the player

Rising quickly

Rotational velocity is like, helicopter rotor speed

[little raptor]

are you using this code?

[tidal ferry]

Yes

Verbatim, pasted right into the debug console

Then with the second bit of code you just sent executed after that

Tbh I can probably figure out a workaround using attachto and physics objects given we know it works with the player unit

[little raptor]

restart the mission and try with this instead:

_oldObj = blablaObj;
blablaObj = createSimpleObject [typeOf _oldObj , getPosASL _oldObj ];
deleteVehicle _oldObj ;
blablaObj setVariable ["destination", getPosASL player vectorAdd [0,100,100]]; 
blablaObj setVariable ["speed", 1];
movingObjs pushBackUnique blablaObj 

[tidal ferry]

Will do

Same code as before?

[little raptor]

what same code?

the EH yes

[tidal ferry]

This one

But also the EH yeah sorry

[little raptor]

this is what that code has become

[tidal ferry]

Hurr durr I meant the EH

Yeah I gotcha

Same EH code?

[little raptor]

yes

[tidal ferry]

Cool cool

[little raptor]

that one has no problem at all

[tidal ferry]

Do I replace blablaObj with the varname of the target object?

[little raptor]

ofc yes

[tidal ferry]

Just making

Absolutely certain

That did... something different

It shifted position a little ways down from where it was originally at in the air

Rotated maybe like 90 degrees

Correction, now oriented to perfect north

[little raptor]

what do you use for speed?

[tidal ferry]

Same thing you posted

Literally verbatim minus changing the varname

[little raptor]

I have no idea then

[tidal ferry]

Same 😆

I'll just cook a workaround with attachto and the player unit

Thanks a ton for your time and patience

[little raptor]

I mean my direction code is not 100% correct

but I don't know what that has to do with position

let me fix that too

[tidal ferry]

Up to you

[little raptor]

if (missionNamespace getVariable ["alreadyExecuted", false]) exitWith {};
movingObjs = [];
alreadyExecuted = true;
addMissionEventHandler["EachFrame", {

      _up, _up, 
      _interval
    ];
  } forEach movingObjs;

}];

[little raptor]

try this instead

[tidal ferry]

Will do

Same setVariable code?

[little raptor]

yeah

[tidal ferry]

Same result

[little raptor]

if (missionNamespace getVariable ["alreadyExecuted", false]) exitWith {};
movingObjs = [];
alreadyExecuted = true;
addMissionEventHandler["EachFrame", {
  {
    _obj = _x;
    _p1 = getPosWorld _obj;
    _p2 = _obj getVariable ["destination", _p1];
    _dist = _p1 vectorDistance _p2;
    if (_dist  < 0.1) then {
      movingObjs = movingObjs - [_x];
      continue;
    };
    _speed = _obj getVariable ["speed", 1];
    _dir = _p1 vectorFromTo _p2;
    
    _obj setVectorUp [0,0,1];
    _obj setVectorDir _dir;
    _velo = _dir vectorMultiply _speed * diag_deltaTime;
    _obj setPosWorld (getPosWorld _obj vectorAdd _velo)
  } forEach movingObjs;
}];

@tidal ferry what about that?

[tidal ferry]

Trying it

No visible effect

Wait I entred it wrong one sec

Same result as before

Just rotates to exact north and lowers by a few hundred meters

WAIT

It's slowly moving

Think we may have got it

[little raptor]

this code moves the object

it has nothing to do with velocity transformation and stuff anymore

if your object doesn't still move the problem is your object

[tidal ferry]

Okay awesome

Guesss we're just cursed then

[little raptor]

you are

[tidal ferry]

Fantastic

I'll have a look at this and see if I can reverse-engineer further

[fair drum]

Someone posted this in the armadev subreddit and it got me thinking since I don't really know the true answer to give him.
https://www.reddit.com/r/armadev/comments/rgjdz0/question_about_publicvariable/

My thought is that it is going to send the whole variable over again if he modifies the variable and throws the public again.

[tidal ferry]

Oh my God, @little raptor, thank you 😆

You have no idea how much time you've saved me here

[little raptor]

what? did it work?

[tidal ferry]

Yup

The last code worked

[little raptor]

you said no

[tidal ferry]

Oh sorry

I said no, but then realized I typed it wrong

Then I corrected it and ssaid it worked

My bad 😅

That last iteration worked

In SP, at least

Going to test it for MP but should be just what I need

Thanks a ton for your time and help and patience

No way I would have been able to sort it with my sanity intact

[dapper cairn]

So sorry if this isnt the right channel for his but if there a script/trigger i can place on a radio for the players to interact with and activate to set off a bunch of explosives?

The players basically mouse wheel on a radio and select a function and it sets off a series of explosives

[still forum]

It sends the whole variable

[vivid estuary]

quick question. whats the best way to execute a slot restriction script for a Dedicated server?

currently i have it as

init.sqf
[] execVM "Scripts\Restrictions\PilotCheck.sqf";

PilotCheck.sqf
https://www.sqfbin.com/bovavopomebalegosuju

[vivid estuary]

on the radio init field

this addAction ["Detonate Explosives","Scripts\Explosvies\Detonate.sqf'];

Detonate.sqf
_Bomb1, _Bomb2, _Bomb3 setDamage 1;

thats probably wrong or at least a round about way of doing it. im sure someone has a better idea of how to do it.

[echo smelt]

Anyone here know much about Sql work and database work?

[little raptor]

yes, it's wrong

[hallow mortar]

The addAction should have some extra parameters so the players can't activate it from the default 50-metre range. (https://community.bistudio.com/wiki/addAction)
The detonation script needs some tweaking. For example, to apply a command to multiple targets, you would need a forEach and an array:

{ _x setDamage 1; } forEach [bomb1,bomb2,bomb3];

But the setDamage command may not be right - it doesn't work with all explosives. You might need to instead use the ol' reliable fallback:

{ _bomb = createVehicle ["Bo_GBU12_LGB",_x,[],0,"CAN_COLLIDE"]} forEach [targetobj1,targetobj2];```
The script also needs some way to remove the action once it's been used. If it's okay to remove all actions from the radio, then `remoteExec` and `removeAllActions` will be all you need. If you want to only remove that specific action and leave others, it gets a little more complicated.

[dapper cairn]

this addAction ["Destroy Charges",{ _x setDamage 1; } forEach [charge1,charge2,charge3]];

Okay... so im using a radio (ground static item) to set off the satchels... im close but now with the above line they just go off when nothing being pressed aka, the Destroy Charges action was not selected

[warm hedge]

this addAction ["Destroy Charges",{{ _x setDamage 1; } forEach [charge1,charge2,charge3]}];```

[dapper cairn]

I love you

[past wagon]

If I take a plane (with a pilot in it), put it in the air in the exact direction I want it to fly in, and give it a waypoint also in the exact direction I want it to fly in, then what type of AI should I disable in order for the pilot to fly in a completely straight line and not make any deviations from the path? anyone have any suggestions?

[mossy lark]

You could just use unitCapture and unitPlay for that

[mossy lark]

https://www.youtube.com/watch?v=q2BTPgpWcMg

[past wagon]

that was my initial thought, but will I be able to have it fly in a straight line in a random direction?

[mossy lark]

good question, not sure

[past wagon]

ok I will check it out

yeah, I don't think unitCapture is a good option for me. I need it to fly for like 4 minutes

[crude vigil]

A script was provided to you, what happened to that?

[past wagon]

I assume you mean this:
#arma3_scripting message

Yeah I forgot to respond to @tough abyss (my bad, thanks a lot for writing the script) but that script won’t help me since using setDir mid-flight will reset the plane’s velocity to zero.

[crude vigil]

then modify the code to preserve velocity as well (you will also need setVectorUp, otherwise plane may tilt)

[signal hazel]

Hello everyone! Havent posted in a while here, and the time has come. I've been making a custom tank composition for a while now, and some problems have stopped me from completing it. Its a Jagdtiger, and ii havent had any issues till the cannon of the tank. Originally i wanted to use a flak36 cannon, but there are no "animateSource ["base_Hide",1]; and so the base of the cannon sticks out. So I used the Pak40, hid the wheels and stands and locked it in place. there are some issues with it too! the cannon is mad tiny and when i try to attach anything to it, and move the tank, the attached item to the pak40 glitches back and forth like crazy. Any solutions to that? Either to use the Flak36 without the base (legs) or to attach a barrel to the >cannon< of the Pak40, so it can turn with the cannon, if it can be done. Thanks in advance! (pls ping if you have any answers)

[leaden merlin]

Very simple question here. How can I get a vehicle to move once people gave boarded it? I'm really lost on how to trigger this properly.

[versed widget]

if !(isNull objectParent player) 
then {while {speed vehicle player >= 200} 
do {addcamshake [5,5,5]; sleep 0.3};};
}```
can someone help me with this, it seems that the statement has no effect at all until i flip the greater than to smaller than

[winter rose]

if the player is in a vehicle then do something (else do nothing) and leave

[pliant stream]

jesus christ that formatting

[versed widget]

i still didnt get it, i took the example from the wiki
if (speed _truck1 >= 100) then {hint "You're going too fast!"};
i just changed the _truck1 with vehicle player, no hint appeared after hitting 100

[winter rose]

that's because the check is immediate

it's not wait until vehicle's speed >= 100

[versed widget]

ah ! well that explains it

[leaden merlin]

This is a scripting issue that I'm lost on because I'm just a dumbdumb I guess. What I am trying to do is better understand how in missions you can have transports function well. My goal with the included mission sample is trying to get the transport to pick me up, drop me off, move ahead and wait there, and do that a few times. The only workaround I found was by disabling the AI to move and create a proximity trigger between me and the vehicle, but this is absolutely ineffective because it will only work once and not repetitively. Obviously transports aren't limited in this way, so I want to learn how to accomplish that.

Sample is in the VR map with vanilla assets so I tried to make it available for anybody to give me novice pointers here. Big thanks to anyone who wants to help what's likely one of the easiest questions regarding the editor. :p https://www.dropbox.com/s/50zewz0bmn003nw/WhatOnEarthAmIDoingWrongHere.VR.pbo?dl=0

It's missing triggers btw as I've been messing around the last two hours and still haven't a clue what I'm doing. Ignore that as the "obvious" mistake. Look at it as a template where I'd like to see a working solution.

[tough abyss]

Waypoints?

Could just set waypoint condition to wait until you're in the transport

Move to scripted location

Repeat arbitrary times

[leaden merlin]

What would be the most efficient way of doing that? Like, the easiest way to set it up that any group that has that waypoint would meet the conditions. I've seen some for the player but I was hoping to better understand groups.

[tough abyss]

@leaden merlin Depends how you'd want it implemented

Would you want the entire group to be in the transport before it moves or just one or two or ?

Lots is left up to your discretion

[leaden merlin]

whole group, ideally. I'm absolutely lost on it

[tough abyss]

Well for the most basic implementation of that it'd literally just be this for the condition

_allInVehicle = true;
{
  if (vehicle _x != _vehicle) exitWith {_allInVehicle = false};
} forEach (units _group);
_allInVehicle

With _vehicle being the transport in question and _group being the group in question

obviously many ways to implement it and this is just barebones

but it's the general idea

you'd probably want to handle cases where the vehicle can't fit the entire group

[leaden merlin]

I think I understand the conditions of that, but my brain is completely fogging out seeing it all click in the editor. That would be the trigger, yeah?

[tough abyss]

That would be the waypoint condition for the initial movement

so if that's what you mean by trigger then yes

[leaden merlin]

So, big picture, how would this go? Disable the driving AI at a pickup spot, link the waypoint trigger as above with the condition to move so it can move, and repeat that?

[tough abyss]

Yup pretty much

as I said the fine details are largely up to you but that's the gist of it

[copper raven]

you can write it like this: units _group findIf {objectParent _x isNotEqualTo _vehicle} == -1

[tough abyss]

technically you could shorten the above code to just

((units _group) findIf {vehicle _x != _vehicle}) == -1;

---

yup

was just writing that

though I did a forEach because the iteration may come in handy for other checks you may add in the future

cleaner to add more lines to the forEach than to chain conditions in a findIf

[leaden merlin]

The trigger just needs to be linked to the vehicles waypoints too, right?

[tough abyss]

In 3DEN?

[leaden merlin]

Yes

[tough abyss]

Not sure about the specifics of how 3DEN does it but that sounds right

I usually only set up waypoints via script

[leaden merlin]

thank you this worked

I have been trying to grasp this all morning.

[tough abyss]

Glad it worked and glad I could be of help

I would heavily recommend looking into the group-related commands on the wiki if you want to get a better grasp on working with them

https://community.bistudio.com/wiki/Category:Command_Group:_Groups

[leaden merlin]

My issue was trying to understand the start-and-stop logic behind the transport itself. It wasn't so much whom to set as a trigger but more about how the underpinnings of it go.

[tough abyss]

Ah, that's fair enough

Hopefully this served to make things more clear then :)

[leaden merlin]

It did!!!

[final sun]

Hello,I have a simple question. Can a custom function be called inside an event handler? I'm getting an error and I'm just checking I'm not looking for the wrong thing.

[proven charm]

sure can

[final sun]

Weird, I'm getting an undefined variable in expression. But both variables are defined and exist. I even tried hardcoding the variables and the result is the same

[tough abyss]

Show code?

[final sun]

https://sqfbin.com/upaboqivefefapowakig

lines 55-76

[tough abyss]

What's coming up undefined?

[willow hound]

_unitTargetFunc 🙃

[tough abyss]

Would make sense if that's the case

local function definition trying to be called from an EH

[final sun]

"Error Undefined variable in expression: _unitTargetFunc"

[tough abyss]

Yup alright then

_unitTargetFunc is locally scoped

the EH does not get run in the same scope when the player dies

thus the function does not exist and you get that error

if you want to fix that you'll either want to make the function globally scoped via some means or pass it as a param to addEventHandler

nvm thinking of something else for the latter

[final sun]

Thanks for the info, If I make the function global though It seems I have to make a lot of my variables global as well otherwise it throws a similar error but this time for the function. I though it was never a good idea to make anything global am I wrong?

[tough abyss]

Functions are generally best made global unless you have a good reason to pass them as parameters

Or more simply unless you're not accessing them from outside of the local scope

In your case you need global access to the function for how you're trying to do this

As far as causing more errors

That'd be because you're accessing vars that are part of that file's local scope as part of that function

The thing to understand is that this is what's happening

Your file runs -> file defines locally scoped functions and vars -> sets up Killed EH -> file ends -> locally scoped functions and vars no longer exist

so then when your EH code gets run it's trying to call a function that no longer exists

same with your vars that your function uses such as _Threats

so you need to either make those vars globally scoped or rethink how you're doing things

[final sun]

That's a really good explanation, thanks I'll look into it. Though I might pick the lazy way and just make them all global even though I might regret it later

[tough abyss]

Global is only evil if you use it poorly

It's more about knowing when/how to use things than avoiding things entirely, they all have purpose

[vivid estuary]

Glad somebody is smarter than me

[frozen seal]

Hi everyone!
So I can get all nearest tanks using this:

_all = nearestObjects [_this select 0, ["Tank"], 50];

What should I replace "Tank" with to get list of all nearest projectiles/bullets?

I tried "Bullet" and "Projectile" but that's not it.
Is there a doc page with a list of all available object types?

[tough abyss]

@frozen seal So a couple things to consider here

As I had to do this same sort of detection for my current mod

Firstly, I'm going to assume you're aware that that command only gets the nearest tanks within 50m, not all tanks

Secondly, the command and methodology to use is going to change depending on what you're trying to detect

As far as object types go you're just using class names, so if you look through config viewer that is essentially your list of object types

Combine that with inheritance and you can fine-tune what you detect

Now the main thing for you to keep in mind is that there is no general class that all projectiles inherit from

[frozen seal]

yeah was about to ask that

[tough abyss]

Generally all bullets inherit from BulletCore/BulletBase

but projectiles in general vary widely

from RocketCore/ShellCore/etc.

depending on what they are

[frozen seal]

I see. Let me give you a broader context of my problem. I'm trying to modify this script to work with tanks. Right now it only works with small arms and tank machinegun but not tank main gun:

_projectile = nearestobject [_this select 0,_this select 4];

setacctime 1;
_camera = "camera" camCreate (getpos _projectile);
_camera cameraeffect ["internal", "back"];
while{alive _projectile && alive _camera}do
{
_camera camSetTarget _projectile;
_camera camSetRelPos [0,-13,1.2];
_camera camCommit 0;
sleep 0.00001;
};
if(alive _camera)then{sleep 0.1};
_camera cameraeffect ["terminate", "back"];
camdestroy _camera;
setacctime 1;

I'm super new to scripting (but not to programming in general) so I might be missing some obvious things

I figured _this select 4 returns the current projectile type and it works fine with small arms, but for some reason it fails to work with tank main gun (nearestobject returns null)

[tough abyss]

Generally nearObjects is better for detecting things like projectiles than nearestObject/nearestObjects

So that could be part of it

Other than that I'm not sure, so I'd give that a shot

[frozen seal]

Sorry for noob question but scripting synthax melts my brain after years of coding in C#

I can't make getPos work in this case:

_pos = getPos _this select 0;
_projectile = _pos nearobjects [_this select 4];

(the script called from "fired" event, so if the documentation is correct _this select 0; should return the shooter, however I still get type mismatch error)

[hollow thistle]

https://community.bistudio.com/wiki/SQF_Syntax

unary operator has higher precedence than binary

getPos _this select 0;

getPos _this => result

result select 0

change to getPos (_this select 0);

projectile should be passed to fired EH btw

[frozen seal]

That still gave me errors (something about 1 element provided, 2 expected).
But your advice about fired event having projectile argument is correct. No need for nearestobject. I wonder why did the original author use it.
Thank you!

On a related note, anyone know the classnames for the MLRS explosion?

Or really just, the largest possible explosion in vanilla arma 😆

E.g. "HelicopterExploBig" but b i g g e r

[tidal ferry]

Also what does this mean?

[digital hollow]

forward vectorCrossProduct up gets you the right side direction vector

[little raptor]

_newDir = vectorDir _unit vectorCrossProduct vectorUp _unit
_unit setVectorDirAndUp [_newDir, vectorUp _unit];

[brazen lagoon]

this is kind of a #server_admins question but I think its a bad script or something

what is a normal count of guaranteed messages?

as in, 3000 guaranteed messages in a second. that's really high, right?

[tidal ferry]

How does one go about using https://community.bistudio.com/wiki/BIS_fnc_transformVectorDirAndUp?

[leaden merlin]

Another question here! Looking to see how to get waypoints working in a script. For example...

"waitUntil {leader group player in truck1};"

How can I alter that to clear when a group enters the truck? I can understand individual units, but I wanted to get it working with a group. I tried replacing that with a group name directly, so unless that has to be formatted differently, I'm a bit lost.

[little raptor]

how to get waypoints working in a script
what does that have to do with waypoints?

and you can't suspend in waypoint statements so I have no idea what you're talking about

[past wagon]

How would I use setVectorDir to make an object completely level to the horizontal?

Sea level…

[tidal ferry]

Why do vectors have to be so confusing

[little raptor]

that would be setVectorUp

not dir

[little raptor]

wat?

what's confusing about vectors?

[tidal ferry]

Just terminology, trying to describe rotations and such

Anyways- still having trouble with the thing I'm trying to do

I need to "pitch" an object I have about 90 degrees

Irrespective of rotation

[past wagon]

Ohhh right thanks I was confused

[tidal ferry]

Need to execute the script with multiple different objects, each with different rotational orientations

[little raptor]

you said you wanted to rotate about Z tho

pitching is not rotation about Z

[tidal ferry]

Sorry, terminology

I'm new to vectors

[little raptor]

it's about X

[tidal ferry]

Okay

So then, how to pitch it 90 degrees relative to its current orientation?

[little raptor]

you have to change the vectorDir and Up:

_y = vectorDir _obj;
_z = vectorUp _obj;
_x = _y vectorCrossProduct _z;
_newZ = _y;
_newY = _newZ vectorCrossProduct _x;
_obj setVectorDirAndUp [_newY, _newZ];

this is -90 deg rotation about X

[tidal ferry]

Okay, thanks, I'll try this

[little raptor]

if you want +90 negate _newZ

[tidal ferry]

Dumb question- how doess one negate _newZ? Isn't it an array?

[little raptor]

vectorMultiply

[tidal ferry]

So like... _newZ = _newZ vectorMultiply -1?

[little raptor]

_newZ = _y vectorMultiply -1

[tidal ferry]

Gotcha

[little raptor]

and even if you didn't know that you could just do:

_y apply {_x * -1}

[tidal ferry]

Worked like a dream

Fantastic

Well, I'm figuring out now that apparently the model is upside-down 😆

Think I need to roll it 180 on the y-axis

[little raptor]

because you put the code in the wrong place

[tidal ferry]

No no, it's because of the model

I thought rotating it 90 degrees would work perfectly

Which it mostly did

But it needs to be rolled 180 degrees after that

So I need to rethink this a bit

Okay so

Pitching -90 degrees, then rolling 180 degrees will work

My single brain cell is feeling pretty confident in that

Let me see if I can figure this out

Yeah nope clueless

I'm sorry, I'm a writer, not a mathematician

[little raptor]

180 deg roll is just reversed up

[little raptor]

vectors are mostly about imagination, not math

[tidal ferry]

Okay, so _z multiplyVector -1?

[little raptor]

_obj setVectorDirAndUp [_newY, _newZ vectorMultiply -1];

[tidal ferry]

Bless 🙏

[little raptor]

also it's vectorMutiply...

where on earth did you get multiplyVector

[tidal ferry]

It was a gift from my last remaining brain cell

Finally got it working as intended, thanks so much for your help and guidance @little raptor 🙏

[real tartan]

how can I parse Line One (something) from string Line One (something)<br/>Some Line two</br> ?

[little raptor]

find

[pliant stream]

quaternions is where it's at. don't need to think about vectors 🙂

[little raptor]

not supported in Arma

SQF has native matrix and vector support so it's several times faster

and easier

[pliant stream]

sqf doesn't offer any matrix interface either though

[little raptor]

it does

[pliant stream]

really

those vectorBlahBlah functions, do they work on vectors of any dimension?

[little raptor]

2 and 3

[pliant stream]

lame

what a missed opportunity

oh there is matrix multiply and transpose

but you can't get or set the transform matrix of an object can you?

[little raptor]

you can make it yourself

[pliant stream]

well not really

[little raptor]

_y = vectorDir obj;
_z = vectorUp obj;
_x = _y vectorCrossProduct _z;

_mat = matrixTranspose[_x, _y, _z];

[pliant stream]

now do skew

[little raptor]

that gives the rotation matrix

wat?

[pliant stream]

you know what skew is, yes?

[little raptor]

no

maybe I call it something else

[tidal ferry]

Hey, so does anybody know the best way to check what an object's 3den layer is?

I'm working on a script to help our missionmakers optimize their missions, but I'm having trouble finding a simple way to grab 3den layer on a specific object

Is that information available to check from an object in a mission?

[cosmic lichen]

https://community.bistudio.com/wiki/Eden_Editor:_Layer Did you read that?

Getting the layer an object belongs to is not possible IIRC.

[tidal ferry]

Hrm

Well, is there any way to list all available 3den layers?

[little raptor]

what about getMissionLayerEntities?

and then finding the object is the list of objects?

[tidal ferry]

That's my current working plan

[cosmic lichen]

That would work but it's not a direct way

[tidal ferry]

Just need a way to find all missionn layers

[cosmic lichen]

from object to layer

[pliant stream]

https://i.imgur.com/aucHxvL.png

[little raptor]

we call it shear in mechanical engineering

[cosmic lichen]

to get all layers, use
getMissionLayerEntities layerID together with for

[little raptor]

and why would I?

objects have no shear in Arma

[pliant stream]

well some do

not your objects

[tidal ferry]

Wait, how would I use that with for?

Wait found it I think

[little raptor]

I'd assume you loop until the layer is empty

[tidal ferry]

https://community.bistudio.com/wiki/getMissionLayers

Perfect

Got it

[cosmic lichen]

Ha! Didn't remember that command 🤦‍♂️

Perhaps I should fix see also on the biki done

[pliant stream]

lots of fences and walls placed on sloping terrain are skewed

[little raptor]

sure, but I don't think it's really needed to take into account

[pliant stream]

how's that?

[little raptor]

because you can't "set" the shear

[pliant stream]

right, that's the problem isn't it?

that there is no object setTransform matrix command

[tidal ferry]

Another question for params specifically

So, I want my script to only accept object datatype

So currently params looks something like...

params [["_object",objNull,[objNull]]];

(I'm aware this is bad, will clean it up later)

But, for data type argument

What do I put there?

Do I just put something referencing an actual object? Or do I need to put a string like "object" or somesuch in?

Or well, better example would be like

params [["_trueOrFalse",true,[true]]];

Might've answered myself but still would love to be sure

[little raptor]

btw isn't that just a visual thing? (only res lod)

or all lods skewed?

[little raptor]

it's already correct

[pliant stream]

It's part of the transform matrix

Why wouldn't it be all lods

[little raptor]

I don't know

[pliant stream]

It's no different from rotation

[little raptor]

undesired effect or something?

[tidal ferry]

Sick, thanks

[pliant stream]

You know setting the transform would give you scaling too

[little raptor]

well at least you can get it in A3

and set it too

but not as a matrix

[pliant stream]

Oh really

I didn't know you had scaling control in A3

[little raptor]

it's new

[pliant stream]

What command is that

[little raptor]

setObjectScale

it's scalar tho, not vector

[pliant stream]

Oh

Lame

[fervent kettle]

using the following

titleCut ["Transport zur Front wird vorbereitet...", "BLACK FADED", 18, false ,false];
*some code*
sleep 16;
*some code*
sleep2;
titleCut ["", "BLACK IN", 2];

in theory it should wait 18 seconds with black screen before returning to normal, right?

[winter rose]

depends on what "some code" is
also sleep 2

[fervent kettle]

@winter rose

        [west, "HQ"] sideChat "Transport is being prepared!";
        sleep 3.5;
        player enableSimulation false;
        titleCut ["Transport zur Front wird vorbereitet...", "BLACK FADED", -1, false ,false];
        [player, ["hmvv", 125, 0]] remoteExec ["say3D", ([0, -2] select isDedicated), false];
        sleep 16.0;
        titleCut ["", "BLACK IN", 2];
        player enableSimulation true;
        sleep 2.0;
        _player setPosATL (getPosATL createRespawn vectorAdd [random 3, random 5]);

[little raptor]

can't you control all that using one titleCut?

[fervent kettle]

I dont know

basically, the black should last 18 secs before returning to normal

[tidal ferry]

Can you assign variables to simple objects?

[winter rose]

such as?

[tidal ferry]

Using setVariable

[still forum]

Yes you can

[tidal ferry]

Sick

[still forum]

I'm pretty sure CBA uses that for their namespace thing

[fervent kettle]

I got it to stay black, but how do I end the black now 😮

[winter rose]

How you did should do

[little raptor]

why not locations?

[still forum]

There was bug once where map processed locations even if invisible and it killed map fps

Don't they use location and simple object now? Depending on global or not?

[little raptor]

ah yes:

if (_isGlobal isEqualTo true) then {
    createSimpleObject ["CBA_NamespaceDummy", DUMMY_POSITION]
} else {
    createLocation ["CBA_NamespaceDummy", DUMMY_POSITION, 0, 0]
};

_isGlobal isEqualTo true

well simple objects have local version too...

why not use that then?

[winter rose]

it's also a (meh) way to check, whatever the provided data type 😬

[fervent kettle]

it somehow cuts it out midway through

[still forum]

Didn't have back then

[still forum]

Is CBA code, they know what do

[winter rose]

the meh is more about the fact that a potential non-boolean would reach here ^^

[still forum]

[winter rose]

I dream of a super strict language like C# is (was?) and despise JS and its ===…

Let me tell you about a thing called Enforce Script

harr harr 😁
yeah I heard the legend…

[vivid estuary]

anyone know anything about registering items for ACE Fortify and executing a pushback on fortify_locations?

i have my script for it but it keeps throwing an errors for missing ; or ,

https://www.sqfbin.com/izowesunefaqecojavum

[steel fox]

is it still acex? didn't some of that change due to the merge?

[steel fox]

yup, seems like it changed https://ace3mod.com/wiki/framework/fortify-framework.html

[vivid estuary]

huh. coulda swore theyd left it backwards compatible but whatever. cool. good looking out.

[faint oasis]

can we attachto and enable the "Freelook" ?

[little raptor]

no

[faint oasis]

oh we can't thx for your answer Leopard20

[past wagon]

can someone please explain to me the syntax for the Vector3D array that I need to use with setVelocity? I just need to set an object's speed to a set amount, say, 500. The other elements I would like to leave as they are. It says it's in the format [x, y, z] but I'm not sure what is what.

[plush nova]

where is unit init called/local to? it seems like editor-placed units run their inits on the server

is this true for created units too? or are those created wholly-locally

[faint oasis]

the "Init" for an object in the editor is run in global so it's run for each clients and the server

[plush nova]

Sorry I mean the init in the cfgvehicles def

If you createunit is that also run everywhere?

[tough abyss]

Yes

[past wagon]

in better terms, how would I use the command to simply set the plane's forward speed to what I want, and not have the plane move in any other directions?

[tough abyss]

The velocity vector is just m/s along each axis

So set the velocity along the direction you want

Which is most easily done by setting the velocity to the vectorDir multiplied by your desired velocity

@plush nova also group locality can mess things up, so even though it's global you should exec the command on the client that the group is local to

And then it should have no issue creating the unit on other clients as well

[plush nova]

So I should only call createunit if the group I'm adding it to is local, basically

[tough abyss]

Yeah, though you could get around that with a remoteExec to the client that it's local to

[plush nova]

Right, call createunit directly* is what I meant

[tough abyss]

Yup

[past wagon]

or I could just multiply each component by a certain amount and the direction would stay the same but the magnitude would increase, right?

[vivid estuary]

anyone know what the turret path for the tank commander is?

im thinking its [_veh turretUnit [0]] but im just trynna make sure before i bring a server down to change it just to be wrong

[tough abyss]

@past wagonMultiplying the entire vector with vectorMultiply would result in the same as multiplying each individual component and putting them back together if that's what you're asking

If you multiply them by differing amounts it will no longer be the same direction

[past wagon]

ok

well that doesnt seem to be working for me either

can anyone else come up with a script that just makes a plane fly in the exact same direction at a constant velocity for like 4 minutes? because I've been trying for hours and I seem to not be capable of doing so lmao

[little raptor]

just use setVelocityTransformation

[little raptor]

I wrote one here

[plush nova]

Hmm is it generally a good idea to use setvelocitytransformation instead of setvelocity if you want "smooth" movement over mp with fine control

[little raptor]

both are good

setVelocityTransformation needs manual control over movement

[plush nova]

So I noticed my units stutter a little with just setvelocity

(only in mp)

[past wagon]

ok

[little raptor]

you can try that too

[past wagon]

what is the interpolation interval?

[little raptor]

I've written the full script already

[plush nova]

Sorry by manual control do you mean you need to have player control of the unit? Or something else

[little raptor]

I mean you have to control everything

[past wagon]

well yeah but I wanna use my own script

[little raptor]

position, vec dir, up

[past wagon]

ik

[little raptor]

then figure it out on your own

[past wagon]

i mean, thanks a lot for telling me about that command because its literally everything I want in one

[past wagon]

I just don't know what the interpolation interval is

i dont like copying other people's scripts

[little raptor]

it's the amount of interpolation between two desired values

e.g. if you have two points an interval of 0.5 means midpoint

[past wagon]

ok. so what effect does it have on the command in this context?

ohh

is it basically the point at when the changes occur?

or the midpoint between the two sets of states?

[little raptor]

no. as I said it's the interpolation value

0 means state 1

1 means state 2

[past wagon]

ohh

[little raptor]

any value between 0 and 1 is interpolated between state 1 and 2

[past wagon]

oh

so it picks which ever stage you give it via the interpolation interval and sets the object to that stage?

[little raptor]

the wiki already explains it

just read it

[tidal ferry]

Hey, anyone know ACE interaction framework well enough to help me get ace_interact_menu_fnc_addActionToObject working in multiplayer?

...Wait, hold on

[past wagon]

Alright well I've read the wiki a few times and I no longer have a clue what this command does or if it will help me at all

why does a plane flying in a constant direction at a constant velocity have to be this complicated....?

[plush nova]

what it actually does isn't set velocity

the velocity you give it is a "hint" for mp sync

basically what you're saying when you call setvelocitytransformation is "this object is on rails between point A and point B"

and the interval is where on the rail it is

[past wagon]

so it instantly sets the object to that point on the rail?

[plush nova]

the velocity does nothing on SP

yes

on MP the velocity is designed to be a "best guess" of how fast you're moving on those rails

[little raptor]

it does
it sets the object velocity

[past wagon]

okay then this command has nothing to do with what I need

[plush nova]

oh yeah that's fair

although most usages of it i've seen hit it on eachframe anyways

so basically the way you could use it is each point in time you set it to a different place on the rail, and if you do this on every frame this looks like movement

[tidal ferry]

nvm

I am a buffon, carry on

[past wagon]

ohhhh now it makes sense

but if I have a specific point in the mission when I want the plane to start flying, then how does the onEachFrame EH work?

wouldn't that be initialized at the start of the mission, so my code would start running right away?

[little raptor]

you add the event handler whenever you want

[past wagon]

okay

and its a mission eh

okay that makes sense

if I have the starting position, ending position, and direction of my object, what should I put for the velocity? I want the velocity to remain the constant

[tidal ferry]

Is there any way to check from inside of a script if it is called, or spawned?

E.g. if a called function is accidentally spawned, it will abort and return an error

[little raptor]

just use setPosWorld, getPosWorld, setVectorDirAndUp, etc. individually

and velocity is _p1 vectorFromTo _p2 vectorMultiply _speed

[uncut sphinx]

Can I use hashmaps the same way one would use dictionaries in Python?

[steel fox]

Yes

[little raptor]

that's what a "dictionary" is - a hashmap

[uncut sphinx]

cool, wasn't sure if there was any additional subtlety

[pallid prairie]

Hello! Modding a legacy version of DayZ Standalone, 0.28, fully in SQF, and I'm having an issue. Since DayZ is all Enforce now I figured I'd have luck here. I'm trying to figure out how to allow scripts to run in a loop in the background on my server, first in the form of a debug menu showing FPS, location etc as a hintSilent. I've tried a few different things in my init.sqf, including call compile preprocessFileLineNumbers "debug.sqf" and [] execVM "debug.sqf" and neither method results in my debug menu appearing upon joining my server. debug.sqf is a simple file that starts a while loop and should call hintSilent with information about my name, UID, blood, shock and FPS. This script works perfectly in 0.14 but not in 0.28, is there something I am doing wrong?

This used to be easy as pie when I ran a 0.47 server so I'm probably missing something really simple

I added a diag_log to the sqf file and it isn't being logged so that must mean my script isn't even being called for whatever reason. Meanwhile I have a script in my root directory and use call compile preprocessFileLineNumbers for the hive saving script and it calls and loads just fine

[surreal gorge]

not s ure if right place, but is there a way to edit weapon attributes? like increasing range of MPRL AA?

so i'm using _someUnit attachTo [player, [0, 0.04*25, 0.04*25], "pilot", true]; and it seems to work fine in SP, but on MP the attached object doesn't seem to follow the bone rotation

[jade acorn]

https://community.bistudio.com/wiki/BIS_fnc_attachToRelative

[plush nova]

is there a way to do this onto a specific bone?

it doesn't seem to have that option

[jade acorn]

yes you're right, I know that it works properly tho

but I think I have found a solution for you

wiki says you could use setDir and then _attachedObj setPosASL getPosASL _attachedObj to synchronize the movement over network in MP

also you have this

_expl1 = "DemoCharge_Remote_Ammo" createVehicle position player;
_expl1 attachTo [player, [-0.1, 0.1, 0.15], "Pelvis"];
_expl1 setVectorDirAndUp [[0.5, 0.5, 0], [-0.5, 0.5, 0]];``` in the wiki, could try adjusting this for your needs to see if it works

[plush nova]

thanks, i'll try it out

[winter rose]

have you read the documentation?

[formal sentinel]

Yes, but because there are two 1's, it's confusing...

[winter rose]

the documentation's syntax does not use ones…

[hallow mortar]

It does, in example 2. But if you look at the Parameters list, you can count the parameters and compare them to the examples to see which is which. Remember: optional parameters can be dropped from the end, but never skipped.

[winter rose]

It does, in example 2

sssyyynnntttaaaxxx

[hallow mortar]

The examples are a demonstration of the syntax intended to help people understand it, no?

[winter rose]

I mean, the "Syntax" part of the doc doesn't use numbers, it lists parameter names

[hallow mortar]

Note: I'm not saying the example is wrong, I'm saying that's where the 1s came from and it's pretty reasonable

[fervent kettle]

which display IDD should I use for players on dedicated server? Just 46?

[winter rose]

it doesn't matter whether they play on a dedi or a player-hosted

[fervent kettle]

then the problem lies elsewhere. In SP and own hosted it works but on dedi it doesn't

[winter rose]

what do you even talk about?

[fervent kettle]

uh ye sorry, displayAddEventHandler

[winter rose]

…about what

it's a dedi, it doesn't even have interface

[fervent kettle]

adding a key-bind function

basically "Press Alt+F4 to Zeus yourself"

[winter rose]

Then you can
On players' machine

[fervent kettle]

Atleast I got that part right , but somehow it is not doing it on dedicated server

that's what's in my init.sqf

doSomeStuff = (findDisplay 46) displayAddEventHandler ["KeyDown", "if ((_this select 1) == 54) then {_nul = [] execVM 'someScript.sqf'};"];

[pliant stream]

does 46 exist?

[fervent kettle]

46 is just the mission, so I'd assume yes?

[pliant stream]

assert (!isnull findDisplay 46)

[fervent kettle]

with the "assert" part?

[pliant stream]

what?

[fervent kettle]

if I should put the assert before the brackets, I have never seen that word

[pliant stream]

assert (!isnull findDisplay 46);
doSomeStuff = (findDisplay 46) displayAddEventHandler ["KeyDown", "if ((_this select 1) == 54) then {_nul = [] execVM 'someScript.sqf'};"];

[fervent kettle]

that's somehow also not working

[pliant stream]

anything in the logs?

[fervent kettle]

Nope, it ends with the mods being loaded

[pliant stream]

well at least we now know for certain that 46 exists

[fervent kettle]

yea

[vague geode]

Is there any way to find out how much blood a unit is loosing?

I know about the isBleeding and getBleedingRemaining scripting commands but I would like to know how heavily a unit is actually bleeding as in how many of those blood stains (slop_00.p3d) are getting created by the units injury...

[tough abyss]

@fervent kettleI doubt it'll change anything, but just out of curiosity it might be worth trying to pass a code param rather than a string

May be a strange side-effect of the string needing to be compiled

[digital rover]

I'm modifying an array server side and making it public with publicVariable. If called multiple times in 1 frame in an unscheduled environment, is the game smart enough to only update clients 'once' rather than spamming them?

Right now I'm making all the changes and calling publicVariable once, assuming that it isn't smart enough.

[tough abyss]

I don't believe so but someone who knows the implementation details might know for sure

[fervent kettle]

how would I go over doing this?

[tough abyss]

doSomeStuff = (findDisplay 46) displayAddEventHandler ["KeyDown", {if ((_this select 1) == 54) then {_nul = [] execVM 'someScript.sqf'}}];

[fervent kettle]

oh, that's simple and self explanetary

[tough abyss]

@digital rover Regardless I'd look into rethinking how you're doing things if something you're broadcasting is needing to be updated multiple times per frame at all

[vague geode]

Also is there any way to set/give any of the commands returned by currentCommand?

https://community.bistudio.com/wiki/currentCommand

[tough abyss]

You can run various commands that result in those actions but I'm not aware of any command that allows you to just pass those strings as a parameter

[still forum]

No

The network message is sent when you run the command

And it has to, because publicVariableEventHandler is a thing.
