Ramon, you need to split your big problem into smaller ones

lethal ingot
The question is how to address to this player
austere hawk
thx
little eagle
So you wanna know this basically:
how to get the nearest other player from a group leader?
?
vague hull
@little eagle thx a lot :)
little eagle
_fnc_getNearestOther = {
private _others = (allPlayers select {_x != _this}) apply {[_x distance _this, _x]};
_others sort true;
_others param [0, [-1, objNull]] select 1;
};
player call _fnc_getNearest
other player
Except dogs aren't players, they are AI units
little eagle
this should report the nearest other player from the local player
I thought you're searching for players and not dogs
What did I do, Senfo ?
lethal ingot
Dogs have to go after nearest player if he is in the minimal distance radius.
little eagle
So you want to get the nearest player from a dog that is not the group leader of the dog?
are the dogs in the leaders group?
Or do you only want to get the nearest enemy?
there is a dedicated https://community.bistudio.com/wiki/findNearestEnemy command, but from my testing it's pretty shit and unreliable
Dogs have to go after nearest player if he is in the minimal distance radius.
that is too big of a problem to solve at once
lethal ingot
I feel awkward now, too much confusion for a short period of time.
- There is a pack of dogs. They are in group. Doing their buisness, walking around.
- If a player walks into defined radius, they start to run after him.
I need to detect if a player is this radoius (from a group leader) and get his position.
tough abyss
or a non-animal FSM?
little eagle
No idea
tough abyss
like if you createUnit ["Alsatian_F"];
little eagle
Ramon, you really have to go through this step by step
tough abyss
The AI created is actually a soldier AI and you can command it like a human AI
little eagle
otherwise the task is overwhelming
Dogs have no AI in Arma
They just stand around
little eagle
But they don't behave like dogs at all
tough abyss
No they don't...
little eagle
that's just stuff coming from the group
lethal ingot
I am describing the situation, I am writing this AI and it works ๐ All I need is to detect if a player is in predefined radius (from a group leader) and get his position.
little eagle
well to get a position of a unit just use
position _unit
And to check if the unit is near enough to the leader, just use
_unit distance _leader < 50
50 being the predefined radius
lethal ingot
How do I put nearest player into _unit?
little eagle
I think we are going in circles
little eagle
dunno how to link comments in shitty discord
but
_fnc_getNearestOther = {
private _others = (allPlayers select {_x != _this}) apply {[_x distance _this, _x]};
_others sort true;
_others param [0, [-1, objNull]] select 1;
};
player call _fnc_getNearest
just replace player with the dog to get the nearest player to the dog
tough abyss
Why not that ^
little eagle
well if that works
as I said, these commands tend to be very dodgy
and dogs probably don't have valid "targets"
since they have no real AI
tough abyss
Yes, you need to be very defensive with your scripting
lethal ingot
Let me give you an example that doesn't work:
_wilddogs move (getPos ((leader _wilddogs) nearEntities ["man", 300]));
"man" doesn't seem to work
little eagle
of course it does not work
group move position
but
(getPos ((leader _wilddogs) nearEntities ["man", 300]))
lethal ingot
Maybe nearTargets will work, really?
tough abyss
So you need to select the first index occurrence of "man" type
lethal ingot
_wilddogs move (getPos (((leader _wilddogs) nearEntities ["man", 300]) select 0) );
Sorry, that was old code. This doen't work
little eagle
line is too long
tough abyss
@lethal ingot For the sake of your sanity
Don't concatenate all code on 1 line
It makes it harder to debug.
little eagle
_fnc_getNearestOther = {
private _others = (allPlayers select {_x != _this}) apply {[_x distance _this, _x]};
_others sort true;
_others param [0, [-1, objNull]] select 1;
};
private _nearest = (leader _wilddogs) call _fnc_getNearestOther;
_wilddogs move position _nearest;
you'll probably will have to ammend that to filter friendlies etc
lethal ingot
Okey, thanks for you help. I will vanish and leave you in calm now ๐
tender fossil
Can you disable simulation (in A2) on server selectively for different clients?
In other words, to limit sync of unique combination of units for each client
little eagle
I don't see why not
you can't do it "on server", as the command has local effects and has to be executed on the client machines
tender fossil
The point is to decrease the server workload, so I'm afraid it doesn't help to run it on clients only @little eagle
Unless the A2 netcode is smart enough to inform server to stop sending useless updates as long as the simulation is disabled
little eagle
enableSimulation has to be executed on every machine
local effects. "server only" won't work here
tough abyss
@little eagle So whats the effect if enableSimulation is run on the client
but AI reside on the server?
Whats that do?
tender fossil
@tough abyss Yes, I'm interested in corner cases just like that
tough abyss
I was too exploring such a concept
as the server sends update for every thing on the MAP
and I mean EVERYTHING
Why do I need to simulate AI thats 4 - 8 KM away?
little eagle
well duh. otherwise the game wouldn't be synched
tender fossil
@tough abyss You got the point ๐
tough abyss
or even enough distance it doesn't matter?
Reminds me of what Dual Universe is doing.
As you get further and further away for other players
the simulation tick rate decreases with distance
tender fossil
@little eagle That's what we're trying to achieve here... Disable/limit sync of units out of area of interest
tough abyss
TO clients
little eagle
every machine can send updates for any object to any other machine
tough abyss
Ezcoo there is a way to scan through all units on the server side
little eagle
client to server
tough abyss
and disable their simulation loop.
little eagle
server to client
tender fossil
@tough abyss That's what I'm about to do
little eagle
doesn't matter which machine owns the object
tough abyss
But just get ZBE_cache
little eagle
Arma 2
tough abyss
Ugh...
Right.
{_x enableSimulation false; } forEach allUnits;
ArmA 3 adds enableSimulationGlobal
tender fossil
Yup
But the A2 netcode... Does everything go through server or is there also P2P/from client to client sync?
little eagle
there is no P2P afaik
tough abyss
It can be done though
A client to a client message
At least in arma 3
remoteExec from my client to remote client
tender fossil
@tough abyss But it's an exception, not done by default? (And the remoteExec could be broadcasted via server anyways, but dunno how netcode works in that case in reality)
@little eagle Thanks for info
tough abyss
I as I was saying looking for a way to shutdown simulation
of AI local to client
If they are a certain distance I mean why do even send updates where there is no one nearby?
Sounds like a waste?
@lavish ocean Do you have any input on this? As you said part of the AI brain could be offloaded using headless clients, is there a way we could disable the other part of the brain if not near them?
I mean it says what has to happen on the server everything needs to be simulated even when not nearby
Why bother?
Sounds like a waste of resources to me...
tender fossil
@tough abyss It's the famous network bubble that's been a hot potato for years, since DayZ at least
I remember talking with Dwarden about it some time ago
little eagle
pretty sure remoteExec goes through the server when the target is clientB and it's called from clientA
tender fossil
So there's no P2P
little eagle
the clients don't know the owner ids of objects
little eagle
well there could still be some P2P in internal stuff that has nothing to do with SQF and remoteExec
but that would mean that you somehow can lose connection between clientA and clientB and both still are connected through the server
that would be a common scenario in P2P situations
But I've never seen that. It's always one client that looses connection to the server and then rubber bands on every other machine
tender fossil
Mhm
little eagle
So I take that as evidence that there is no P2P

load (vehicle player) always returns 0... is there an equivalent for vehicles?
little eagle
no

how about a BIS_fnc or CBA
little eagle
Not that I know of. Cargo boxes use the x slots for weapons/items/magazines/backpacks system.
little eagle
I think the total mass thing is broken though
bar just goes over the maximum
doing nothing
weak tiger
thats if you load via script yes
but trying to drag wont work
so whats determining that condition
i assumed it was linked to its supplyrating (ie supply40 = 40kg)
like a backpack
weak tiger
sorry 40 mass yes
little eagle
it's an arbitrary size number
weak tiger
40.. units
little eagle
yea
weak tiger
but yeh i assumed it was the same as it seems the same in game
little eagle
it probably is
little eagle
you can't get this correctly
e.g. attachments of weapons or items inside backpacks that are inside the cargo
weak tiger
my scripts empty backpacks where possible
reducing that problem
but yeh its a problem

broken forge
Trying to test this and it doesn't seem to be working:
_locationType = ["NameCity", "NameCityCapital", "NameMarine", "NameVillage"];
if (position player == _locationType) then {
hint "Hello World";
};
what is locationtype ? is it a marker ?
broken forge
Basically I'm trying to get a loop of the player's location on a map, and if the _locationType is met then it'll display the BIS_fnc_infoText function instead of every 5min regardless or not the _locationType is met.
dusk sage
If the location type is met?
broken forge
Here's what I have so far:
while {true} do {
waitUntil {time > 5};
_locationType = ["NameCity", "NameCityCapital", "NameMarine", "NameVillage"];
_nearestCity = nearestLocation [getPos player, toString(_locationType)];
_hour = floor dayTime;
_minute = floor ((dayTime - _hour) * 60);
_second = floor (((((dayTime) - (_hour)) * 60) - _minute) * 60);
if (_minute < 10) then {_minute = format ["0%1", _minute]};
if (_second < 10) then {_second = format ["0%1", _second]};
_time = text format ["%1:%2:%3", _hour, _minute, _second];
_month = date select 1;
_monthToYear = ["JAN", "FEB", "MAR", "APR", "MAY", "JUNE", "JULY", "AUG", "SEP", "OCT", "NOV", "DEC"];
_day = date select 2;
if (_day < 10) then {_day = format ["0%1", _day]};
_date = text format ["%1 %2 %3", _day, _monthToYear select (_month - 1), date select 0];
[text(_nearestCity), str(_time), str(_date)] call BIS_fnc_infoText;
sleep 300;
};
Oh my lord
broken forge
As you can see it'll always call BIS_fnc_infoText every 5min, and I want it to only call BIS_fnc_infoText when the player's nearestLocation matches the _locationType array. (And yes that script does work.)
this my work or at least be a little easier to convert:
if (nearestLocation [getPos player, toString(_locationType)];) then {
[text(_nearestCity), str(_time), str(_date)] call BIS_fnc_infoText;
};
What do you mean match the locationType array?
And I don't see how that's working either. You're calling toString on an array of location classes
broken forge
would that edit work?
broken forge
thanks to HorribleGoat the script now works the way I want it to, here's the final resault:
while {true} do {
waitUntil {time > 5};
_locationType = ["NameCity", "NameCityCapital", "NameMarine", "NameVillage", "Airport"];
_nearestCities = nearestLocations [getPos player, _locationType, 1200];
_nearestCity = [_nearestCities, player] call BIS_fnc_nearestPosition;
_hour = floor dayTime;
_minute = floor ((dayTime - _hour) * 60);
_second = floor (((((dayTime) - (_hour)) * 60) - _minute) * 60);
if (_minute < 10) then {_minute = format ["0%1", _minute]};
if (_second < 10) then {_second = format ["0%1", _second]};
_time = text format ["%1:%2:%3", _hour, _minute, _second];
_month = date select 1;
_monthToYear = ["JAN", "FEB", "MAR", "APR", "MAY", "JUNE", "JULY", "AUG", "SEP", "OCT", "NOV", "DEC"];
_day = date select 2;
if (_day < 10) then {_day = format ["0%1", _day]};
_date = text format ["%1 %2 %3", _day, _monthToYear select (_month - 1), date select 0];
// hint format ["%1",_nearestCity];
if (position player distance _nearestCity < 600) then {
[text(_nearestCity), str(_time), str(_date)] call BIS_fnc_infoText;
} else {
// hint "DEBUG: NO LOCATION NEARBY";
};
sleep 300;
};
The script now runs every 5min and will only call BIS_fnc_infoText if the player is 600m or less from a specified location type within the _locationType array.
little eagle
But why didn't you use the BI function to format the date?
little eagle
hmm. I can't find it. I swear there was one for exactly this purpose

Hi all,anyone knows how to script correctly a 'hook' waypoint type?
_wp setWayPointType "HOOK";
_wp waypointAttachVehicle cargo;
_wp setWaypointSpeed "FULL";
_wp setWaypointBehaviour "SAFE";
I'm using this code,where _wp is the waypoint obtained through 'AddWaypoint' command, and cargo is the vehicle that the helicopter should hook.
As now, the helicopter is going near the vehicle,and then is flying at mid-air without doing nothing.
jovial nebula
Err,anyone there?D:
little eagle
yes, here. But I have no idea. Never done that. Never even heard about it
little oxide
@broken forge Use this function to convert time [dayTime] call BIS_fnc_timeToString; Thanks to @little eagle mentioned it

I would use _time = [dayTime] call BIS_fnc_timeToString; but it returns with quotes wrapped around the time.
tender fossil
Hey, it's me again about the enableSimulation in A2
If i have (on dedicated server) clients with IDs 3-10, each having some units, can I disable their simulation on clients 11-20 locally?
In other words, does the disabling of unit simulation happen in the end of receiving client or on client that owns the units and computes their simulation on dedicated server?

x3 = [1,2,3,4,5] select {
if (_x == 3) exitWith {
false;
};
true
};
// x3 = false
bug, feature, bad design?
noble juniper
holy shit, i never noticed that select has so many alternative syntaxes
@little eagle thx for asking that question
@little eagle as far is can read, you are using alternative syntax #5
that returns an array.
you should scrap the if, the == allready makes a boolean stement out of it. Maybe the exitWith fucks it up ?
Yes, the exitWith actually makes x3= false;
little eagle
it was meant to report:
//x3 = [1,2,4,5]
obviously there are better ways, but I removed the out of context code
I'll add a comment on the wiki that escaping the code block scope is not safe
noble juniper
Awesome!
little eagle
note placed: https://community.bistudio.com/wiki/select
tough abyss
while {true} do {} in some instances is bad programming practice
overall.
Particularly if you can come up with a better way of doing it.
As quick said you could run an infinite loop using for
It's less "intensive"
Which is stuffed up logic in itself.
I think that works?
tough abyss
Oh that works?
dusk sage
yep
tough abyss
I thought step 0 it might complain
dusk sage
from x to y step 0
tough abyss
k
for "_i" from 0 to 1 step 0 do {//Less CPU intensive code WTF // };
I still think that is weird
compared to while {true} do { with sleep inside it }; ?
@dusk sage Is this now frowned upon _value = if (condition) then {return value} else {other return value};
little eagle
What does this select quirk have to do with while {true} do { ?
tough abyss
It was _value = if (condition) then {return1} else {return2}; asking if it was frowned upon
then @dusk sage suggested using select instead @little eagle
As it's "prettier" and probably faster as well
little eagle
Yeah. select. It also works with Booleans:
[0,1] select true // 1
tough abyss
if handleDisconnect return false and disableAI = 1 then the player must dissapears. It's obvious to me (but my iq is too low i know).
little eagle
Is that a question?
dusk sage
Don't put yourself down so hard, my god D:
halcyon crypt
hmmm that select is quite a nice alternative to the if else thing ^^
little eagle
it has one downside
if you actually do SQF inside the then and else block, you can't easily convert it to the select syntax
because both elements of the array are evaluated
tough abyss
Very much so
little eagle
The only reason you would use it is to have the local variable defined inside the main scope
tough abyss
This one is worse
little eagle
I'd rather give the variable a meaningful default value:
tough abyss
_var = switch(condition) do {case 1: {//block//} case 2: {//otherBlock//} case 3: {//LastBlock//} } ;
Gross
little eagle
private _var = objNull;
if (cond) then {
_var = player;
} else {
_var = cursorTarget;
};
same, I try to avoid the semi-ternary operator thing with SQF..
tough abyss
@little eagle there is a mission event handler, the handleDisconnect that runs when player disconnect. If it return true, the player get owned by the server and stay as an AI. If it return false, default behavior, defined by disableAI = false/true; should occur, but what happens is tha player dies and his body lay on the ground.
little eagle
There is a huge trap when using switch like this, @tough abyss
little eagle
switch actually returns true when no condition is met and no default block was defined
tough abyss
O_o
@little eagle I didn't realise you were an ACE3 dev. By the way as an offtopic thing.
little eagle
_var = switch (1) do {
case 2: {};
};
// _var = true
wweeeiirrrddd
little eagle
but what happens is tha player dies and his body lay on the ground.
then handleDisconnect doesn't fire. the player just respawns
tough abyss
handleDisconnect fires ONLY on the server last time I checked?
little eagle
switch returns true in this case. No one knows why
handleDisconnect fires ONLY on the server last time I checked?
correct
tough abyss
So if trying to add it to players
That won't work.
but I remember reading some legacy BS about requiring onDisconnect {}; requiring to be called before
little eagle
I didn't realise you were an ACE3 dev. By the way as an offtopic thing.
I also dev CBA and BWA3 : >
That was fixed @tough abyss
In 1.62 iirc
tough abyss
Are you also a "genuine" programmer? As in it's your professional job?
tough abyss
Eh only way to learn to design programs pen + paper
Everything you can code you can step manually.
If you understand the underlying language.
if you use handleDisconnect, all the players disconnecting are doomed to 2 destines: if alive 1 - turn into a AI, 2 - get killed and fall on ground / if dead 1 - stay dead.
little eagle
I just always liked logic and math (as long as it doesn't get too complicated)
little eagle
What are you trying to do, Don?
tough abyss
More I've learned about computers more i've liked math.
All the really cool stuff requires Discrete math.
I'm just saying something is not working as it should be lol
No problem on my side since i delete the body
Get player state?
to be fixed on those next weeks of Arma 3
little eagle
Iirc the handleDisconnect return value thing was always wonky
no idea why you'd even use that
tough abyss
@little eagle to save players on data base if they use Alt + F4 or any other problematic disconection
tough abyss
ah yes
i don't need to the player turn into a AI and walk free on the map, so i return false. And what happens it that the unit (ex player) dies and stay dead on the ground
and i have disableAI set to true
so false must dissapears the unit
little eagle
I can't even remember what it was supposed to do in the first place
tough abyss
but... nothing that _player spawn {deleteVehicle _this;} can't solve;
little eagle
You can also just return nil and it will do nothing
little eagle
Oh, I think I get your confusion now
tough abyss
You could try that.
Not sure how you'd get it to execute on a single client though.
I can't delete the unit inside the handleDisconnect because it crash the server
Maybe remoteExec inside the HandleDisconnect
Add him to the GC
addToRemainsCollector[entity];
little eagle
well. if handleDisconnect was executed, then the client is gone. no way to remoteExec anything
tough abyss
i just believe false should behave acordingly to the setting disableAI in description.ext
but if nil makes it do nothing, its a solve ๐
I also write a lot on paper
help on think
even on real work, need to do that sometimes
sometimes need paper and pen... can't find.. sad
so i write in any free paper i find
noble juniper
@tough abyss did you get handleDisconnect working ?
i got an error from BIS_fnc_addStackedEventhandler that the event is not supported
and the documentation is forwarding to onPlayerDisconnected.
little eagle
handleDisconnect only works with addMissionEventHandler
tough abyss
^
little eagle
it's not to be confused with onPlayer(Dis)Connected
tough abyss
Any particularly reason you are using HandleDisconnect
?
vs PlayerDisconnected
?
tough abyss
Ah.
Override: If this EH code returns true, the unit, previously occupied by player, gets transferred to the server, becomes AI and continues to live, even with description.ext param disabledAI = 1;
Theres your reason @tough abyss
So make it so
little eagle
Apparenlty returning false does make it behave like disabledAI was 0
tough abyss
Well you could just kill the AI
little eagle
But he wanted to be whatever was in the description.ext
tough abyss
then delete his body.
noble juniper
You can achieve DayZ SA like combatlog behavior
little eagle
He doesn't want to override anything. He's making a mod I think and not a mission
tough abyss
A question about performance of server-side communication missions vs the clienside + server-side systems used
Is there any performance benefit in making a mission SS only?
noble juniper
SS = ServerSide ?
tough abyss
Yes
So all your speciality code exists inside a @modfolder
vs just using the mission file
tough abyss
@tough abyss s version of I&A had mostly server-side components
Used a single mission.sqm and description.ext binding to server-side functions
noble juniper
well, if boil arma scripting down to the basics
the only thing of interest is how you get your code and how you get it executed.
tough abyss
So a SS system is really no better than the CS+SS hybrid used for most missions?
@noble juniper
CS -> Client Side
SS -> Server-Side
noble juniper
the only difference is how you get your code, "streaming" it from the server obvoiusly adds latency and network traffic
but i sadly don't have benchmarks / measurements on how much traffic and latency.
noble juniper
in my AL experience, you could offload pretty hughe scripts onto the server on 100 people servers, without problems
Well AL = problems but never mind
noble juniper
that is and upcoming task for me thoug
little eagle
Pretty sure it's not meant to save performance, but to simply have the clients not have to download and install a mod
noble juniper
well normaly, the Modquestion is a different one
tough abyss
Check out #headless_client to see what I did
The mod for QS's I&A wasn't client side
It was exclusively server-side
as you said it "streamed" the functions from the server.
noble juniper
i actually don't get what you wanted to achieve with that
tough abyss
HC in my perception was effectively a second script executer
which it was.
It was seeing I could specifically restrict code to specific HC's
Which it did work.
noble juniper
yes
tough abyss
And with the HC's are they have unlimited bandwidth and no latency
little eagle
You could also write code that doesn't slow down the clients... No unnecessary polling loops etc. Having it all on a server seems like a unnecessary limitation
tough abyss
It gave me access to a second single-threaded script executor
noble juniper
i know, i helped Secrets of Altis implement that like a year ago ๐
sorry im just an evil and old AL dev
But, nice that you made that experience and nice that it worked, congratulation
tough abyss
I mean the community I manage has a single Xeon. 12 thread CPU server
So utilising HC's
Is very useful.
noble juniper
that is an interesting choice
noble juniper
and you are right, you basically need to use HC to utilize all of it
tough abyss
One issue I can't seem to workout
AI + Lots of gunfire = low FPS
I am not sure why.
little eagle
cause of the bullets flying
noble juniper
have you automated the install, update, restart of all of those HCs?
noble juniper
are you working with GIT or SVN ?
tough abyss
Linked to the HC's folder inside 1 folder
noble juniper
or even Maven ?
tough abyss
just copy and paste. No.
tough abyss
I used symbolic links to move, my entire arma 3 install to SSD without.
Just me...
I manage the entire server / scripting
I changed RDP ports
Locked down security
Setup firewall
IIS 8.5 ArmaA3Sync server
noble juniper
in my opinion, you should start using Version Controle like GIT. From a software engeneering standpoint, it only has benefits.
noble juniper
i don't like source tree its to complicated for me to be honest
tough abyss
I do like the snapshot feature of it.
noble juniper
i use gitkraken
tough abyss
I use crossed fingers and hope
tough abyss
googles gitkraken

lmfao
tough abyss
I just have a lot of confidence in myself ๐
SourceTree had problems
When I tried to make multiple branches
actually speaking of confidence, I tried to make an arma mission and I have no fcking clue what I'm doing
noble juniper
i guess everything is personel preference
dusk sage
Tutorials to click the branch button? ๐ค
tough abyss
No...
To not cause things to depend on others.
E.g branching can screw up an entire snapshot
dusk sage
What you on about D:
noble juniper
tut on how to add a remote, clone , fetch
basically how to set it up and get it running reliably, but never mind
tough abyss
Heh gitkraken actually has a better interface than SourceTree
Hows it's documentation?
noble juniper
and is multiplatform
tough abyss
Support bitbucket?
noble juniper
there are tips and tricks on theire twitter
yes
bitbucket and your own hosts like gitlab and such
tough abyss
So uh, could someone help me out in the #arma3_scenario channel? I'd love to, ya know, make missions, but I have no fcking clue what I'm doing wrong.
Heh they updated it.
noble juniper
@BoGuu#1044 that actually looks better then what i remember from sourcetree
noble juniper
but im on linux so no sourctree for me
dusk sage
Don't really need any docs to use it
dusk sage
It's just git bash with nice buttons

Git bash command line scared me.

Learning it.
Was from a hackers book but.
I wasn't enough of an intro.
I had to buy a C programming book to fully understand it.

i don't remember that there was a sqf lexer for NP++
tough abyss
Yeah there is.
I updated mine manually though.
To include all the new commands
It's upto Version 2.0 now.
noble juniper
do you mean "highliting" ? or also Syntax check for all the commands and such ?
noble juniper
like, expected array got bool ?
noble juniper
with that intelli J plugin of cause
tough abyss
Is there a problem with it?
tough abyss
I'm actually learning 4 different languages, the 4th is kind of forced because of playing FTB
Lua.
Python.
C
and ASM
tough abyss
Wow.
noble juniper
tough abyss
Neat.
noble juniper
the free community eddition
tough abyss
That would cut my coding time down a lot
I've often added accidentally syntax errors
noble juniper
it atleast cathces a lot of syntax shit
tough abyss
And gone why doesn't this work?
tough abyss
Some commands.
tough abyss
Does it pick up the embedded () problems?
noble juniper
yes
tough abyss
Nice.
noble juniper
missing ;
it will in general look up what that command wants, and if you did syntactical shit like, a string instead of an array it should actually report that
in theory, damnit i cant make it do that now, damn. But ctr Q is wiki lookup , so in case you can look up the command in the IDE
tiny wadi
Any idea why a trigger deactivation runs globally?
tough abyss
Because you have to specify if it runs globally
when you _trig = createTrigger ["EmptyDetector",getPos (ofThing),true];
tiny wadi
I placed it down in the editor, anyway to disable that?
tiny wadi
Ok, will it still hint to the player that triggers it?
tough abyss
No.
It will be evaluated on the server
to hint the player
you'd have to do this.
in the onActivation field
"Message" remoteExec ["hint",owner(this)];
This way the trigger will be evaluated on the server
but state passed to the client.
tiny wadi
I feel like im doing it incorrect, what I ahve is a trigger that brings up a dialog and does some stuff to a car. Should the server be involved?
tough abyss
Give us the code to look at?
tiny wadi
Sure
activation:_exc = [vehicle (thisList select 0), "addonshop_2"] execVM "addonshop.sqf";
deactivation: hint "Thanks for visiting Adam's Auto Parts";
Grabbing script
tough abyss
Okay so what happens when a trigger is executed on the server only
Is it will be evaluated on the server only
tiny wadi
addonshop.sqf
tough abyss
So any client-side operations won't show up
tiny wadi
Its best to open the script in notepad++ to read the comments correctly
tough abyss
So what doesn't it do?
tiny wadi
Run only on the client
little eagle
if (isNil "AddonShop_Car getVariable ""Addons""") then {
^ this is borked. doesn't work like that
tiny wadi
That was actually the only way I could get it to work
tough abyss
No.
little eagle
this will always be true, so you'll always reset that "Addons" variable to []
tough abyss
^
little eagle
I think you meant:
if (isNil {AddonShop_Car getVariable "Addons"}) then {
spring kindle
So was wondering if someone can help me out here, arma is saying my script isnt being found... https://gyazo.com/b10e38bceeaf3be3f6455ec223e1e5e9 https://gyazo.com/6648157a834c8b613484c7131d01e199
tiny wadi
That makes sense, I noticed everytime I ran that it reset my addons for some reason
little eagle
use my edited version
tiny wadi
@spring kindle Make sure that you specify the path to the addon folder if it is in an addon
tough abyss
isNil now support code block conditional eval?
spring kindle
tiny wadi
_Flush = execVM ""\RLM\Toilet\Flush.sqf""
little eagle
isNil now support code block conditional eval?
it has always supported that
tough abyss
Otherwise it has no idea where to find it.
So provide it the full path to the .sqf file
@little eagle Didn't know that.
I'd always seen it used in this context isNil "varable";
spring kindle
tame portal
What on earth would the flush.sqf do
tiny wadi
Make sure addonbuilder is accepting .sqf in allowed file extensions
little eagle
isNil string checks if a variable is defined (either local variable or a global namespace of the current namespace)
dusk sage
Use defaults!
little eagle
isNil code checks if the expression has a return value that is not GameValueNil
tame portal
missionNamespace getVariable ["varname", defaultValue]
@dusk sage I agree
dusk sage
ninja'd
tiny wadi
How do params work?
spring kindle
wooow yeah addon builder wasent excepting sqf
tiny wadi
I never understood them
tough abyss
You can do clever things like this
Your code with the [_var,_var] spawn {code}
you can do this
tame portal
params is just a stack of the param command
tough abyss
to define them without using _this select #;
tame portal
How come its wrong?
little eagle
param is a glorified select and params assigns variables and sets them to private
they do different things
tame portal
Well
tiny wadi
Oh so I could do [1,2] spawn {params ["_a", "_b"]; hint format ["%1, %2", _a, _b];
tough abyss
e.g [_ExternalVar1,ExternalVar2] spawn { [_firstVar,secondVar] params ["_myNewVar",_myOtherNewVar"]; };
Yes
little eagle
one is return value based, the other directly assigns the variables
tough abyss
Can also do it with script commands
tame portal
param has the same functionality except it doesnt declare the variables by itself and it only works for one of the parameters given
tough abyss
AddEventHandlers make this really easy.
tame portal
Thats why I said its kinda stacked ^^
tough abyss
Take all the variables of the addEventHandler feed it into [] params
little eagle
so params is not just a stack of param's. thank you
tough abyss
which would be each _this select #
tame portal
Everyone sounds so hostile here..
tiny wadi
rip
tame portal
I was just trying to give a reason why I call it "stacked param" because thats the way its stuck in my head, I know it doesnt work the same why but they are both share the core functionality of processing parameters
Wasnt trying to prove you wrong
little eagle
it's a bad way to remember them, because it is wrong and leads to false assumptions
tough abyss
addMissionEventHandler ["PlayerDisconnected" { params [_id,_uid,_name,_jip,_owner] }];
Now you could use _id etc variables
little eagle
you have to stringify the variable names
tame portal
Well I know the difference but yes, for someone who doesnt know the difference its misleading
little eagle
params ["_id", "_uid", "_name", "_jip", "_owner"]
tough abyss
derp. I've been away from ArmA 3 Code ๐คฆ I apologise if my syntax is wrong.
tame portal
All gucci
little eagle
param is a super usefull command
mainly because it get's around the flaws of select with out of bounds
and handles default values really nicely
they even fixed the index being -1 in 1.64
tough abyss
I wonder if ``` _fnc_getDataLong = {
_longDate = date params ["year"," month", "day"," hour", "_minute"];
_longDate;
};
Ahhhh thats why that wouldn't work.
tiny wadi
so if I want to set a default value on paramsI would do: params [["_myVar", 1], ["_myString", "asd"]];
tough abyss
So I'd have to do this.
little eagle
yes
tiny wadi
and if the variable is set when I call the script it wont use the default
tame portal
So does params return false whenever atleast one parameter is not given or of the wrong datatype?
tough abyss
_longDate = date params ["_year","_ month", "_day","_ hour", "_minute"];
_longDateRet = [_year,_month,_day,_hour,_minute];
_longDateRet;
};
??
little eagle
It's really weird. I think it only returns true if every variable was provided and they all match the required type
tame portal
Fair enough
little eagle
that would do nothing , Geeky
that would be the same as just date
you split the array into it's elements and reassemble it immediately again
So even if you have one value being undefined it will report false
even if a default value was defined
little eagle
[1] params ["_num1", ["_num2", 0]]; // false
tiny wadi
Preferablly without doing the server stuff
little eagle
because it's a global trigger?
tiny wadi
How do I make it a local trigger?
little eagle
player in thisList or something
tiny wadi
Oh in the condition
little eagle
would check if the local player is inside the trigger
spring kindle
can someone spot the error? I'm having no luck. https://gyazo.com/24e2201c25882072dc0341e154edca55 https://gyazo.com/cc1f5c6b139f296fc1f759594132f9b3
little eagle
_flush is undefined.
spring kindle
what is the point in that?
tiny wadi
The script doesnt know what the value is unless you get the variable you passed it
vapid frigate
how else does it know what '_flush' is?
tiny wadi
Because it is not a global variable
spring kindle
arma still doesn't agree https://gyazo.com/044cfa506c7930a60e9179281d754a06
tiny wadi
show the init event handler again
spring kindle
tough abyss
select this value
So the way execVM works
when you state [_this select 0] execVM "myScript.sqf"
It normally refers to A a parameter inside another script passed by another script
so if you were to [this] execVM "myscript.sqf";
spring kindle
so is select 0 like selecting that object?
vapid frigate
select 0 is just selecting that value from the array
like _this[0] or _this.get(0) in other languages
spring kindle
okay well no more errors but now im not animating
tiny wadi
Do AI & players activate triggers or can any vehicle activate it?
little eagle
omg
tough abyss
tbh you kind of need to work things out yourself @tiny wadi
We can't hold your hand all the way...
@little eagle You able to help me with an issue in #server_admins ?
Or know of someone who can?
spring kindle
@tough abyss thanks for walking me through this issue i think maybe the this's cacled eachother out who knows lol but this fixed it. https://gyazo.com/ac9cc3d80882089d3d3058d679c5da72 https://gyazo.com/06693d8f6286b43f9965c0af45ff6b36
tough abyss
Oh yeah.
You didn't know that the statements?
have to be ""?
Some of ArmA 3 script requires ""
Supposedly not absolutely sure if you define code using quotes or {}
ArmA 3 treats them the same.
But that could be a VBS 2.0 / 3.0 only thing
As I said not absolutely sure.
paper rain
the "" is a double-quote escape, so double-quotes can be stored in config fields, like mission.sqm mission init fields
I.E. how do you store a " in a string? By escaping it as ""
tough abyss
Yeah in some other languages they use e.g
Python \ escape character
"my string with it's escape character" and it's not going to cooperate. with me using backslash between the it's
spring kindle
so how would i make a player go into a custom animation
tough abyss
call it?
spring kindle
i've looked around and haven't found anythjing helkpful;
tough abyss
Do you know the class name of the animation?
spring kindle
its a custom one i made
tough abyss
spring kindle
so that will animate a player as well?
tough abyss
That can animate anything
spring kindle
how would i make that work for a player?
tough abyss
player animateSource ["MyAnimationClass", 1, true];
or
player animateSource ["MyAnimationClass", 1,1];
true ending value == instant change
number 1 == smooth change
spring kindle
@tough abyss do you know how to set it up model side? i imported the rtm into the animations window but i dont know how to go from there since its not a selection
tough abyss
No never done modelling
This is the sort of stuff I read / do
I have done some modelling in the past
But it wasn't arma 3 related
It was Blender 3D CyclesRendering
spring kindle
alright ive been digging in the exampls folder and i think i may have figured it out im about to find out ill let you know
vapid frigate
i don't think animateSource works on units
that's for model config type animations (doors, wheels, etc)
I think you want https://community.bistudio.com/wiki/playMove or one of it's 'See Also's
lethal cave
allMapMarkers returns #user defined markers, is it possible to take an id that it returns and get a player name?
lethal cave
well it returns all placed markers on the map, i wanna use it my spectator thing to show markers for spectators
and show names of who placed the markers if it's a user marker
it probably wont work cause if player with this ID disconnects script wont be able to find his name anymore
lethal cave
not sure how that would help
paper rain
Here's something similar to what you want to do. I remember old wasteland servers in A2 added the placer's name at the start of the marker text: http://killzonekid.com/arma-scripting-tutorials-whos-placingdeleting-markers/
For the following marker. I'd use https://community.bistudio.com/wiki/onPlayerDisconnected to delete the marker. (or https://community.bistudio.com/wiki/Arma_3:_Event_Handlers/addMissionEventHandler#PlayerDisconnected)
I'd also have the client run a tight infinite loop setting the marker position, creating it when they spawn.
lethal cave
oh wait, it's markerText not getMarkerText, okay, how did i miss that
that was helpful, thanks
thin pine
Whats that command that allows you to return all valid scripting commands for arma 3? Returns it like B: somethingsomething

there are no classes in SQF, so no
median iris
Anyone willing to help me understand function creation? Or point me in the right direction? I have a good understanding just want to make sure I do it right?
thin pine
@twilit nymph define class
median iris
Thank you for that link it helped a lot but my next area of confusion is the call BIS_fnc_param I don't understand why this: _name = [_this,0,"",[""]] call BIS_fnc_param; is different from this _position = [_this,1,"",["",[]]] call BIS_fnc_param; any thoughts or recommendations?
why all the extra ]]] and such what do these define?
twilit nymph
@thin pine Not experienced with ArmA scripting but like a function containing custom code that I can call from IG
noble juniper
@median iris bis_fnc_param is an old way of making sure that a variable contains the right value and that there is always a value set on it.
param or params is the new engine based way.
thin pine
@twilit nymph It depends where/when you want that function defined. But you could just an in-line function. Define the in-line function init.sqf, call it IG using the 'call' or 'spawn' commands
twilit nymph
Like remove items and add new ones to a unit
Could you please write some example code or something?
removeAllItems rifleman1;
rifleman1 addItemToVest "ACE_tourniquet";
And as gamemaster I want to be able to call this mid game
For example
twilit nymph
Can I put this in init.sqf and call from debug menu?
indigo snow
you can execute arbitrary code from the debug console
twilit nymph
How?
indigo snow
no need to put anything in init.sqf
if the mission allows it, the logged in administrator has access to the debug console in the escape menu
twilit nymph
I see, problem is though the code I want to run is 99 lines
indigo snow
then you save it in a function and call the function instead
my_fnc = { hint "some"; systemChat "lines"; }; call my_fnc
nocturne bluff
I got 99 problems but a function aint one
open vigil
Hehe
twilit nymph
medic1 addItemToVest "ACE_CableTie";
rifleman 1 addItemToVest "ACE_CableTie";
Is it possible to shorten this somehow?
Like medic1, rifleman1 addItemToVest "ACE_CableTie";
indigo snow
{_x addItemToVest "ACE_CableTie" } forEach [medic1,rifleman1];
twilit nymph
Holy shit I'm new to this. How to best learn arma 3 scripting?
indigo snow
by doing
tough abyss
Because he uses forEach after. To run what is inside the brackets for the medic and rifleman
indigo snow
forEach executes the codeblock to its left for each element in the array to its right
_x is a magic variable with the value of the currently evaluated value of the array
indigo snow
just wait until the attack helicopter lobby gets more funds
twilit nymph
Thanks @indigo snow
What am I doing wrong? {_x removeAllItems} forEach [p1, marksman1, rifleman1, breacher1, medic1];
the _x need to go after items?
indigo snow
look at the syntax for that command
also read the note - it doesnt remove all items
twilit nymph
It worked for me. I know
twilit nymph
Is there an easy way to add custom music to zeus?
indigo snow
it might show up if you set up a cfgMusic inside your description.ext but no promises
tough abyss
_x is a local variable correct
but in the context of a forEach {}
It corresponds to the index that the forEach is currently operating on.
e.g
{
diag_log format ["%1",",_x]
} forEach [1,2,3,4,5,6,7];
On the first run of that _x == 1
second _x == 2
third _x == 3
and so on.
median iris
Anyone mind helping me or providing an example of the params command?
indigo snow
[1,2] call { params ["_a","_b"]; hint format ["%1",_a+_b]; };
tough abyss
you can not use params
where values are undefined though
unless you provide a "default" value
so you can replaced _this select 0
with params
but.
median iris
Thank you for the reply but I think I need something more in-depth I'm trying to create a function that creates a great many markers for various scripts to use, I'm not sure what parameter configuration this script requiers
tough abyss
You must provide default values
median iris
Very well.
indigo snow
The more advanced usage such as supplying default values and accepted datatypes is all explained on the wiki
tough abyss
other wise params ["_someValue"] inside a function thats yet to be called.
The "_someValue" will say undefined variable in expression.
If you want to make a function robust
indigo snow
params has the exact same functionalities
warped thicket
how is that better than params?
it's the exact same thing
sniped there @indigo snow ๐
indigo snow
:ninja:
tough abyss
No it's not.
indigo snow
it is
tough abyss
params is not the same as param
warped thicket
well obviously it's not the same
tough abyss
@little eagle Clear this up?
warped thicket
one is for one parameter, the other is for more
duh
I bet you are talking about this @tough abyss https://gist.github.com/commy2/46d26d9cff33fafec70e181d45a1ffb3
tough abyss
param can be used to eliminate illegal values passed to a function
warped thicket
so can params
tough abyss
I like to use params with. something like getPos
warped thicket
if you have more than 1 parameter, you should use params
tough abyss
I can use params directly with that to seperate the [(getPos player)] params ["_xAxis",_yAxis","_zAxis"];
warped thicket
also params is better because it privatizes the variable itself
param does not do that
that gist from commy even tells you params is better, so not sure why you are refferring to it to prove that param is better ๐
tough abyss
Thats why you'll see private param in 1 line
warped thicket
for the use case we are talking about anyways
well obviously
so why exactly should he use param again?
tough abyss
The main use of this is to check the argument input of called (or spawned) SQF functions.
warped thicket
params [
["_markerName", "", [""]],
["_markerLocation", [0,0,0], [[], objNull], [2,3]],
];
you also don't need private ARRAY above it with that
tough abyss
Hmmm interesting
indigo snow
it's good code but his _markerLocation was index 0
median iris
i see
warped thicket
well then just swap it
tough abyss
One other key thing
Is the params is pass-by-order
Meaning whatever you pass into the function / spawn'd code
twilit nymph
Tried that earlier. Doesnt work @indigo snow
tough abyss
will be the order the variables are arranged
warped thicket
it's always like that
if you use select or param you need to know the index as well
indigo snow
then it its non trivial Cisco
tough abyss
^
warped thicket
for params you can just do params ["_var1", "", "_var2"];
tough abyss
Exactly as I said pass-by-order
without knowing the order other than when it goes in
warped thicket
you need to know the order either way yes
unless it's a function that just passes through entire thing for whatever reason
tough abyss
no more fuggly _hardDefinedOrder =_this select 0
indigo snow
i do not understand the point you are trying to make
warped thicket
params is a lot faster than private _var = _this select X
dusk sage
Anyone done benchmark for param vs params?
warped thicket
param is faster
tough abyss
Feel free @dusk sage
warped thicket
it doesn't privatize
tough abyss
I'd love to know.
warped thicket
don't have numbers at hand
dusk sage
private param vs params more specifically*
tough abyss
params is almost as useful as sort and apply
warped thicket
single backticks for in-line stuff like this
dusk sage
is almost as useful as?
indigo snow
[1,2,3,4] call {params ["_a","_b","_c","_d"];};
[1,2,3,4] call {
private _a param [0];
private _b = param [1];
private _c = param [2];
private _d = param [3];
};
0.0034ms vs 0.0052 ms
tough abyss
relatively I know they do different things it's along the line of them being quite new and under used commands
I even still see a lot of code with
array + array = array3
warped thicket
well that's a rather bad test
tough abyss
instead of array pushBack array2
warped thicket
because param is not meant for more parameters ๐
tough abyss
^
indigo snow
fair, ez to amend
tough abyss
Test with a single parameter
dusk sage
pushBack has also not been around aslong as a lot of older code
warped thicket
"test" call {private _var = param [0, "default"]} -> 0.0027
"test" call {params [["_var", "default"]]} -> 0.0027 ms
dusk sage
You'd hope params and param is linear, though
tough abyss
We need a precision control for diag_codePerformance
dusk sage
But obviously more code etc with param for > 1 parameters
indigo snow
ah jonpas your example coverts "test" into ["test"] first
warped thicket
?
tough abyss
@dusk sage Exactly.
indigo snow
iirc param and params convert non-array inputs into a one element array
tough abyss
On the note of more code. I sometimes prefer to sacrifice a little bit of performance for the sake of readability.
indigo snow
forEach ^^
warped thicket
well you are talking about 2 commands that are pretty much the same for 1 parameter inputs
dusk sage
Negligible compared to the fluctuations you're gonna get testing that shit
warped thicket
you can't expect 0.1 ms differences
oh things like that can bunch up rather quickly if you do some very intensive shit
not worth thinking about in simple scripts though
dusk sage
As with everything coding related, make sure it works first ๐ @tough abyss
tough abyss
^
dusk sage
There isn't that many bizarre unreadable things you can do in SQF
tough abyss
Can always re-write it ๐
dusk sage
I'll ask again in hope; has anyone got ahold of those bitwise functions added?
