They could completely do away with if (condition) then {}
amd replace it with if (condition) { }
indigo snow
they cant, thats not how sqf works
jade abyss
but then you don't have exitWith {}
tough abyss
Ahhh right.
jade abyss
and again:
"Does it matter?"
dusk sage
Of course it does, because JS and PHP and shitty

Only the syntax of select matters, other than that no.

Screwy ass name.
jade abyss
and?
I still don't get, where the point of that Convo is^^
scratching head and b*********
tough abyss
It was in relation to the verbosity of _array select _something
still forum
who uses select anymore? param ftw
tough abyss
and the speed reduction it probably introduces
jade abyss
@still forum Why using param when you know whats in there?
jade abyss
Or if you want the first entry
still forum
cuz... I wanna be anti?
jade abyss
okayyyyyyyyy
tough abyss
Atleast we got slices sort of
_myArray select [beginingindex,endingindex];
And I guess we should be grateful for SQF
rather than SQS (Status Quo Script)
Which results in some seriously bad spaghetti code
dusk sage
You shouldn't be questioning why we don't have array[index], more why something like select has so much overhead
little eagle
I already answered this. Input validation. And it twice as bad for select since it's a binary command.
tough abyss
How much overhead does it have... ?
little eagle
Not much more than any other binary command
tough abyss
hmmm
I thought try catch and throw was best for input validation?
I mean params can provide valid types.
But it can't break out of the code if an "illegal" expression is found.
Ironically try catch and throw got updated
To now accept parameters
e.g
dusk sage
I already answered this. Input validation. And it twice as bad for select since it's a binary command.
Yeh, but like I said yesterday or whenever, that is to a much larger extent than needed
I thought try catch and throw was best for input validation?
In SQF ๐ ?
tough abyss
player try {
if (player != (vehicle player)) then {
throw "Not a vehicle"
};
} catch {
if (_exception isEqualTo "Not a vehicle") then {
//do some exception stuff //
};
};
Doesn't help with anything internal though
It's just some sugar over what we all do anyway
dusk sage
If you like
tough abyss
And allows you to catch the error immediately without running all the exitWiths?
Hmmm wonder how many exitWiths it takes to make the same overhead as the try catch and throw
dusk sage
You're still running through more code than needed
If you wanted to exit with a hint for example
tough abyss
So why implement try catch and throw at all?
dusk sage
if (something) exitWith {hint something};
Instead you're throwing that, then checking what the error is, then hinting
I guess it could be handy
tough abyss
eg?
dusk sage
Certainly neater when you're quite far nested in scopes
tough abyss
Hmmm
dusk sage
Because exitWith won't exit the parent scope. Then again, breakOut is there
dusk sage
I've never tried nesting try catch in SQF, but if it works as you'd expect it to, then it could help
tough abyss
not before so it doesn't result in a goto like expression.
dusk sage
You could start trying to replicate an exception type system you'd expect of a normal language
dusk sage
scopeName "main";
...
......
......... many scopes in, breakOut "main";
Yeah I normally put the scope name after the breakout.
Or below it.
So it follows some normal order of execution.
dusk sage
Why?
tough abyss
{
if (_x isEqualTo condition) then { breakOut "main" };
}
forEach _listOfItems;
scopeName "main";
Does that even work?
dusk sage
I don't think it does
I think it'll exit the forEach
Then continue execution, as your scope isn't defined
{
if (_x isEqualTo condition) then { breakOut "main" };
}
forEach _listOfItems;
systemChat "I'm executing!";
scopeName "main";
etc
dusk sage
Why?
tough abyss
May as well replace BreakOut with goto
dusk sage
How does it know what to breakOut?
little eagle
Pretty sure scopeName needs to be executed before breakTo/Out
little eagle
breakOut is like a retarded return
tough abyss
xD
dusk sage
But a handy one
little eagle
Sure, but this style of code is pure spagethi
dusk sage
Well using purely breakOut as a mean to return, isn't spaghetti
It's as you'd expect a normal return to work
little eagle
breakTo isn't exactly goto either
dusk sage
Indeed, because it jumps forward in execution
But it's the nearest you're getting ๐
little eagle
You only can skip between scopes and not random points in the code like with goto
goto only exists in SQS
dusk sage
But that is good
little eagle
The lack of goto? Sure.
dusk sage
Because I've never really seen a proper use case for goto, where something more elegant couldn't be used
little eagle
There are probably some...
little eagle
No one can agree to what proper SQF looks like in the first place
No point in thinking about hypothetical new commands
dusk sage
It depends on what the language offers you though. I see many people use goto in C#, because it doesn't implement switch fall through very well
tough abyss
Okay found 8 entries in BI functions to scopeName
fn_findSafePos uses it
Interesting
Instead of a lot of exitWiths
little eagle
breakTo is pretty shitty, but I can see use in breakOut's new return value supporting syntax as a pseudo return
I probably even used that once or twice already in this discord.
dusk sage
Breaking out the most parent scope, like a return, is really handy if you're nested in some loops or logic
I use it for quite a few things
tough abyss
Ironic that BIS stores all their location data in configs
Instead of SQF scanning them all
dusk sage
_pos = _this select 0;
_minDist = _this select 1;
_maxDist = _this select 2;
_objDist = _this select 3;
_waterMode = _this select 4;
_maxGradient = _this select 5;
_shoreMode = _this select 6;
hehe
little eagle
It's not something you need when you're new to SQF. It's really niche. A tad bit more useful than try-throw-catch which is just a bad joke.
tough abyss
yeah I know
It would be really easy to change
I've had to do this to a few BIS functions
over-write them with params builtin
crimson adder
(Bit off topic, sorry.) Anyone here have experience with the OO implementation in BIS?
dusk sage
aaaaaah
dusk sage
I'm doubtful anyone here has played with the functions, and from what I hear, it was a somewhat disaster, may be wrong though.
crimson adder
Shoot. Was hoping they'd finally made a proper implementation
dusk sage
commy has a deep bond with SQF, might be worth asking him ๐
little eagle
I don't have a deep bond with what a proper OO implementation would look like though.
dusk sage
Not a bunch of BIS functions ๐
tough abyss
This is the only one I've seen
crimson adder
Was reading some old posts by DnA. Apparently there is some overhead since it's handled with scripting
dusk sage
Indeed, yeh
dusk sage
I think, the C# thing that was posted on here before, might get you a step closer
But I can't remember its name
tough abyss
dusk sage
Or really what it did
tough abyss
Thats the only OOP system I've seen
crimson adder
Hm... I mean, their internal functions make total sense, just haven't tested what performance impact there would be
tough abyss
I'd be more worried about what you might over-write
little eagle
//Automatically call parameter validation whenever a method is called
private ["_compileString"];
_compileString = _methodVar + " = compile ('";
_compileString = _compileString + "if (!([""" + _className + """, """ + _methodName + """, _this] call BIS_fnc_validateParametersOO)) exitWith {" + _returnValue + "}; ";
_compileString = _compileString + (preprocessFileLineNumbers _methodScript);
_compileString = _compileString + "')";
call (compile _compileString);

My unpopular opinion: I don't need OO in SQF.
tough abyss
^
crimson adder
Reason?
crimson adder
(Just curious. If there was a proper implementation)
halcyon crypt
since when is OO something about performance?
little eagle
No. I don't need it. I can do everything without it and I would see no point in using it.
crimson adder
Not looking for perf improvement
tough abyss
SQF is even a bytecode translated language
nor compiled
most of those OO languages use some kind of bytecode or compiled code.
Excluding. Lua.
Python, C++, C, Java bytecode. or compiled.
crimson adder
Ah, I am forgetting about this backend. Sorry, I come from a background of C,C++,Java,.NET on embedded systems
tough abyss
Yeah no SQF is C, PHP, JavaScript had a baby and it was ugly.
crimson adder
Oh god it is
SQF makes me want to stab things
And yet I keep working with it ๐
tough abyss
Especially when you get errors that make no sense.
For example I tried to use a C implementation for looping through a multidimensioal array
using nested for loops
NOPE
SQF doesn't like that one bit.
little eagle
That's just your bad script though.
crimson adder
My face when I found out switch statements were slower than ifs ๐ค
little eagle
: P
little eagle
This isn't C though
crimson adder
Their logic handling it beyond me as well
tough abyss
ASk @still forum if you want to know more specifics.
But he said SQF's script executer is Single-threaded
Unlike C# or C++'s compiler being multi-threaded along with supporting multi-threaded libraries by default.
crimson adder
I can certainly see the challenges with multi threading that
I'd love to see some more "knobs" and functions I could use to maybe implement my own version
That'll never happen though lol
tough abyss
Best you can do is use an external extension
Only issue is the calls to the extensions are single-threaded as well
callExtension etc.
crimson adder
Been looking into that for a little while now. And the issue of only string transfer
Has its own set of crappy problems with its implementation
tough abyss
Why because you need a parser to interpret the data coming from the string?
little eagle
The problem is that you worked with C++ and now you want to have a games scripting language work the same way.
crimson adder
Eh, I go back and forth on the string thing tbh. I see both sides of the argument on it
tough abyss
callExtensions also unscheduled. It is limited in how many loops it can do. 10,000 iterations I think it was, before the extension will be stopped
crimson adder
Very true @little eagle . I need to keep things in perspective
little eagle
Just forget about everything and start over fresh.
And keep in mind that, at least I consider it to be, 90% of the code snippets you find out there are shitcode.
halcyon crypt
crimson adder
I mean, I've been learning the SQF backwards methodology for 3 years now. It's not foreign lol

Never figured it would be. Just a fun hobby

VBS uses a different library.

All of it.
But VBS has a whole bunch of tools

That complains about bad scripts

fix it.
You can even change the way the scheduler handles the scripts
telling it to complete in a single frame or etc.

Which removes everything.
dusk sage
Just stop people opening them?
tough abyss
You can't...
dusk sage
Of course you can
tough abyss
How?
tough abyss
Oh.
Right.
Forgot about the Container open handler
I just wanted a simple system to lock and unlock the container...
dusk sage
if (container getVariable ["locked", false]) exitWith {true};
Okay it's that easy?
little eagle
exitWith might not work in the eventhandlers main scope
little eagle
It doesn't work in handleDamage
halcyon crypt
EH's don't have any scope to exit do they?
as in it's at the top of the "call stack", kind of
little eagle
everything encapsulated with curly brackets is a scope
player addEventHandler ["InventoryOpened", {<this is a scope>}];
halcyon crypt
mhm but is there a scope above the current scope once it fires?
I'd imagine that exitWith doesn't work in init.sqf either in that case
little eagle
Define work
If you call exitWith in the main scope of init.sqf
nothing below the exitWith will be executed
There is no return value that is expected by init.sqf
unlike InventoryOpened
so I really don't see the similarities.
halcyon crypt
they both don't have a parent scope to exit to?
that's why I could imagine it not working in init.sqf as it doesn't with the HandleDamage EH as you pointed out
little eagle
Neither have a parent scope to exit to
jade abyss
init(or any other).sqf:
abc = true;
if(abc)exitWith{};
systemchat str abc
Systemchat won't be executed.
As easy as it is oO There is no witchcraft in exitWith
halcyon crypt
then why does it not work with HandleDamage EH for example?
little eagle
player addEventHandler ["handleDamage", {
if (true) exitWith {0};
}];
^ this does not work
jade abyss
because -> Arma
halcyon crypt
wait, init.sqf is scheduled, isn't it? That probably explains the difference
little eagle
Nah, because the main scope of handleDamage expects a return value, but you leave the scope with exitWith
jade abyss
iirc its for each and every EH.
little eagle
I mean sure Arma, but that is how it works with everything
Except waitUntil for god knows why ....
Literally everything that is not waitUntil
jade abyss
afaik init.sqf is the same as every other *.sqf file. It just gets loaded by the engine automaticly. Marcel
little eagle
Yeah.
And it has nothing to do with scheduled either. My while loop was scheduled to avoid the 10k iteration limit
It's just waitUntil being weird
jade abyss
waitUntil is like a Loop on its own, in its own NameSpace. No chance for ExitWith (iirc)
halcyon crypt
@jade abyss I get that but exitWith not working for EH's is just weirding me out I guess. Always assumed that exitWith kind of meant return _var
dusk sage
It's handled specially due to the rate at which it executes IIRC, it's brought out of context
jade abyss
prolly
little eagle
But can you breakTo to a deeper scope?
jade abyss
I mean... lets see it the logical way:
A script that has waitUntil in it gets executed once, then reaching waitUntil Part, then checking constantly each whatever* s, looping its {XYZ} part
halcyon crypt
@little eagle what about this?
player addEventHandler ["handleDamage", {
0;
if (true) exitWith {};
}];
not that it makes sense due to the condition
jade abyss
Prolly the mainscript gets "cached"/removed from the mainSchedule and only the waitUntil Part is still loaded.
@halcyon crypt Try this: add diag_log "blaaaa" to the EH or define a globalVar in it.
little eagle
0 spawn {
scopeName "main";
call {
waitUntil {
breakTo "main";
false
};
};
systemChat "is this ever reached or not?";
};
logically, it should
little eagle
Well, exitWith didn't reach it
jade abyss
Since you say to that darn thing -> Exit here at this point (breakTo)
So waitUntil should be done
i get headache
little eagle
Yup
jade abyss
maybe worse headache, cause i haven't touched that stuff for > 6 Months ^^
back to Tentacle Pr... movie... less headache
halcyon crypt
my guess would be that the engine implementation of waitUntil prevents breakTo or anything else to work guess not ๐
jade abyss
Or its just a bug/broken.
halcyon crypt
don't know, it seems somewhat logical to me but my logic seems a bit off judging by the stuff above ๐
little eagle
it does print and end the script
jade abyss
Does NOT print? Okay
little eagle
it does
jade abyss
Its too late, my bad
little eagle
now testing:
0 spawn {
scopeName "main";
waitUntil {
breakTo "main";
false
};
systemChat "is this ever reached or not?";
};
wait, you tested what before?
jade abyss
kk
Try this:
0 spawn {
scopeName "main";
waitUntil {
systemChat "1";
breakTo "main";
systemChat "2";
false;
systemChat "3";
};
systemChat "is this ever reached or not?";
};```I'll be testing this first:
0 spawn {
waitUntil {
scopeName "main";
false breakOut "main";
false
};
systemChat "is this ever reached or not?";
};
This is basically exitWith
right?
jade abyss
Can you test that one from me? Don't wanna search A3 in my SteamLibrary ๐
jade abyss
hmmm, okay
At least, it exits. But without result sending over.
screw it, i move my rotten body to the couch.
little eagle
My best explanation is that the code block of waitUntil is being called inside another virtual code block and the return value of the virtual code block is used
waitUntil {<blah>};
is basically
waitUnit {call {<blah>}};
jade abyss
e.g.:
_Time = (diag_TickTime + 40);
waitUntil {sleep 1; diag_TickTime >= _Time};```So yeah, seems to be your last example
No stop, not call
little eagle
why not?
jade abyss
waitUntil spawn{<blah>} <-- ?? ^^
little eagle
You can suspend in call if the call was executed in scheduled environment
little eagle
Yeah, waitUntil has to be
It suspends for a frame
that is it's sole gimmick
And it has only one code block so it's not as much of a drag compared to while performance wise
jade abyss
+you can still use (ui)sleep to suspend it
jade abyss
Depends on what you wait
I mostly used it Changes of Areas
waitUntil{sleep 10; SomethingNotSoImportantButStillNeeded};
I meant instead of waitUntil
while {sleepFrame 1; checksomething} do {}
of course also patch while so you don't need a do block
jade abyss
And i meant: Not checking every frame/second. Just check it every X Seconds.
Also possible with it.
jade abyss
Was while able to use suspend? like
while{sleep 3; Var}do
can't remember
but still... nah, that makes no sense to let a while{true}do doing that
little eagle
You can use suspension everywhere in scheduled environment
crimson adder
^
little eagle
Except isNil CODE, because that is no longer scheduled environment for god knows why
dusk sage
My best explanation is that the code block of waitUntil is being called inside another virtual code block and the return value of the virtual code block is used
little eagle
or the string-code block in configClasses and configPropeties
dusk sage
Can you exitWith {breakOut ""};?
jade abyss
thought something similar @dusk sage
little eagle
0 spawn {
waitUntil {
if (true) exitWith {
scopeName "main";
false breakOut "main";
};
false
};
systemChat "is this ever reached or not?";
};
this, right?
dusk sage
nono just breakOut ""
jade abyss
0 spawn {
waitUntil {
if (true) exitWith {
breakOut "";
};
false
};
systemChat "is this ever reached or not?";
};```
โ ?I'll test mine first
dusk sage
equivalent I think
little eagle
mine loops forever
breakOut "";
is just another breakTo, it will work
wait
uhm no
it loops forever
Idk man
ยฏ_(ใ)_/ยฏ
jade abyss
i guess: Since no targetscope :/
dusk sage
Chances are its taken totally out of context
little eagle
^ this doesn't work
"" doesn't work guys
0 spawn {
waitUntil {
if (true) exitWith {
breakOut "undefined";
};
false
};
systemChat "is this ever reached or not?";
};
"" is just ignored by the command
Yup
With "undefined" it prints the chat message
jade abyss
btw.:
Why is exitWith in waitUntil even needed?
little eagle
It's not, but you can use it as return
little eagle
It's a really confusing syntax as I said
Because it works nowhere else
Never use this
still forum
@tough abyss
callExtensions also unscheduled. It is limited in how many loops it can do. 10,000 iterations I think it was, before the extension will be stopped
What? No!... Arma doesn't care about what happens inside the extension and it can't stop it either. there is a limit on loops yeah.. but totally nothing todo with Extensions
I can't sleep right now so... back to that thingy about _array[index] and if (true) {do this}
SQF is a very easy language. It has variables, arrays, code blocks and 3 types of commands. Commands without arguments.. Commands with one argument and commands with 2 arguments.. Thats It. Thats all of SQF.
_a = 1 Is this a variable assignment? NO! It's a function call. It's calling the function = with the arguments _a and 1.
Same for if.... then stuff... if is a command taking one argument and returning an intermediary "condition object". then and exitWith are commands that take 2 arguments. One "condition object" and a codeblock.
SQF's core principle is that everything is a function call.
So by doing if (true) {code}, which looks like CONDITION CODE to the engine, You are trying to violate the core principle of SQF.. Well actually.. They could just make a whitespace function that takes a "condition object" and a code block... But thats Nuts...
Same for _array[index] how should it know that ARRAY ARRAY should do anything? ARRAY FUNCTION ARRAY is very obvious what it should do.. It's a function call taking 2 arguments. You just can't change the core principle of the language. So all these Ideas about making the language nicer will stay exactly that.. Ideas.
I hope i can sleep now instead of thinking about this the whole time
queen cargo
_a = 1 Is this a variable assignment? NO! It's a function call. It's calling the function = with the arguments _a and 1.
uhm ... nope
it is a variable assignment
= is a special case in SQF
So by doing if (true) {code}, which looks like CONDITION CODE to the engine also false
for the engine it is ( IF(BOOL) )THEN( CODE )
important difference is the IF(BOOL) as the bool after the if gets flagged specially somehow
then REQUIRES an if
even though ... IF does not require then (and just returns the bool itself)
--> _cond = if(true); _cond then {1} else {0} is valid
true then {1} else {0} is not
woeful void
@still forum SQF is a very easy language. Sorry, I would have to disagree, because I'm fluent in at least 6 differrent true programing and scripting languages (C#, C++, Javascript, XML/XSL, VB, PERL, LISP, Forth, assembly), conversant in quite a few others.... and the syntax of SQF only very, very loosely matches the syntax of any that I've seen which makes it hard for someone who already knows one of those other languages, because the change up in syntax is pretty extreme.
However, it is the one we are stuck with for ARMA 3 so that's why I'm trying to learn it.
tough abyss
in my opinion it matches C based languages making it fairly easy
ionic orchid
SQF reminds of me the scripting language at work, grown and patched on to over 15 years into a frankenstein's monster of quirky behaviour and edgecases
dusk sage
@woeful void When you consider that everything is 'well' documented on the wiki, SQF really isn't a hard 'language' at all
ionic orchid
and probably with 15 years of content that uses it that no-one wants to change in order to overhaul it

@X39#2180 important difference is the IF(BOOL) as the bool after the if gets flagged specially somehow IF is both a command and a type in sqf. typename if (true) is of type 'IF' which is expected for the left hand operator of 'then'. supportInfo "*:if" ["t:IF"] a type. supportInfo "*:if*"["u:if BOOL"] a command. supportInfo "*:then*" ["b:IF then CODE","b:IF then ARRAY"]

@dusk sage The reason I call it hard is because it flys in the face of all the other programming habits one picks up when they do programming professionally. What I am pointing out is that knowing other languages can make SQF harder, not easier to understand.

I would argue despite the awkwardness of SQF, knowing other languages has made learning SQF simpler. But when I refer to difficulty, it takes little to no time to become 'proficient' in SQF

Would you be a casual or a professional programmer? Just trying to get an idea as to skill level here, no offense intended.
Actually.. that question isn't relevant to the channel as a whole so I'll withdraw it. Nevermind me.

Is there a way to restrict the contents of a 'RscEdit' to numerical characters?

@woeful void Not only that. There is quirks of the language that... are related to stupid things.
E.g unscheduled code in, EH's show 0 errors

How would I delete every element AFTER a certain one in an array? deleteAt will delete the one I want but not all after it.... I could write an algorithm but there may be a command anyway
indigo snow
Just select from 0 to the one you want and copy them. _array = _array select [0,_index+1]
cerulean whale
It can vary where it will occur... It could be select 3, 4, 5, 6, etc. That's why I just wanted to see if there was a command for it
indigo snow
You only want to remove element from the end I understand? I forgot about resize which even modifies the original like deleteAt
Simply resize to the index of the last element you want to keep + 1
cerulean whale
@indigo snow It's slightly different to that, I just wrote an algorithm for it though, thanks for the help though. I kindof wish they had a command for that but w/e xD.

I meant SQF is very easy from the engine programmers perspective. everything is made up of function calls that makes the backend relativly easy to program.
and @queen cargo i don't understand anything about what you are saying about the if then stuff besides the last 2 lines.

shadow sapphire
Okay. I need help. Anyone game this morning? Here's what I need:
I need a script that either can make autoturrets fire blanks, a script that will make autoturrets fire at assigned targets based on a trigger, or I need an invisible wall that will stop bullets.
Anyone know of any of these??
shadow sapphire
HAha, okay, but how do I do that? I am TERRIBLE.
shadow sapphire
I'm always in over my head. Will it work on autoturrets?
little eagle
Idk, why not? Probably, try it
shadow sapphire
Will try it if I can get the syntax right!
little eagle
What do you have atm?
shadow sapphire
Diving in now. I'll report back soon.
Nothing. I have nothing yet, because I didn't know which way I would go about it. I thought invisible walls would be easiest, but that didn't work at all.
shadow sapphire
Do you think this would be best placed in the turret's init?
little eagle
Is this for a mission?
params ["_unit", "_weapon", "_muzzle", "_mode", "_ammo", "_magazine", "_projectile"];
shadow sapphire
Sorta. It's for a training environment. I want autoturrets to fire at people when they are visible, so that they will get to cover.
But I don't want to kill the people, because on our server, death is a pretty big deal.
little eagle
I posted everything you need. Just 3 legos you have to put together
shadow sapphire
Thanks a ton!
little eagle
If it's for a mission, then I'd use the init box
shadow sapphire
Init box of the turret?
little eagle
Yeah
shadow sapphire
Thanks a ton! I'll let you know if I get it working.
little eagle
Remember to use a local check, because the fired eh triggers everywhere and deleting a projectile is global and at machine gun speed, you don't want to do unneeded network traffic and red chain the server
shadow sapphire
A local check?
little eagle
local _unit
shadow sapphire
I don't understand the context, unfortunately..
shadow sapphire
Oh. Okay! The MG will be on a dedicated server, if that matters.
little eagle
No, it doesn't. Ideally you make your scripts work regardless of who owns the object or who is the server, but that is not the trend these days.
shadow sapphire
Haha, okay, roger.
little eagle
and yes i even tag private vars
madness
it would be a sad little number forever
it would be a sad little number forever
And adding new ehs starts over at index 0
which is the worst part
Just make the event handler self removing
it's OEF, so set a last frame no
And add a new one if that diverges to far
if you're worried about cheaters removing it
shadow sapphire
Okay, what else do I need to know?
this addEventHandler ["Fired", deleteVehicle _projectile];```
I get expected nothing.Invalid number in expression.
I'm trying to fake blank firing autoturrets for a training environment.
Or just make them fire high.
When I pasted your script into the turrets, I get invalid number in expression error. Not sure of exact context.
Worked perfectly locally! Now I just need to test it on dedicated. Thanks so much!
@tough abyss and @little eagle, thanks a ton! Script is working locally. Will test on dedicated soon. If this works, the applications for my group will be expansive!
peak plover
What are the pros and cons to having 1 while loop that runs every second that I add different functions and checks to or having a seperate loop for every function and check? Does the engine handle this on it's own? Would the end result being the same in both cases?
Enjoying is different than having good performance ๐
Squeeze performance out of EVERYTHING
I don't think the quality of life can decrease any further. Would having a loop for caching groups of units rather than spawn a script for every group separately be worth it?
Can't figure out anything better to do...
peak plover
Don't custom events run on every frame?
aah
Oops
I used {}, 5 ] call CBA_fnc_addPerFrameHandler;
Does the 5 still cause performance loss?
Better to use while { } do {}
?
nocturne bluff
No lol
peak plover
Well, I don't want it to constantly run. Just every 5 seconds
halcyon crypt
depends on the condition that you're testing but while { true } do {} probably could use a sleep ๐
peak plover
And in theory, the last run must be complete before a new one is started
^ this is scheduled?
It'll not run a new one before the last one is done
So using PFH in a situation like this http://i.imgur.com/a9rBDTR.jpg is completely wrong
peak plover
What does sleep actually do?
little eagle
And scripting in the scheduler has overhead for every command used
they check runtime after each command to manage the scheduler
you're still making up in the end
peak plover
Isn't the myth that using sleep in scripts lags out the engine true?
little eagle
Idk what that means
sleep ends the execution of the current pseudo thread and puts it on the end of the stack of all the other pseudo threads
peak plover
For some reason, whenever I use sleep in a script. I feel like it's taking something away. And the more of those I use, the more I feel like something is taken from me.
little eagle
So the scheduler can continue with the next item
The real problem here is, that you broadcast a variable every 5 seconds
Idk, but that doesn't sound very optimal
peak plover
Doesn't the thread get cluttered with throwing the pseudo threads into the end all the time?
Only 1 variable is broadcasted along the net
little eagle
The more threads you have, the longer it will take for them all to complete
peak plover
Thanks. That actually makes it a lot easier to read.
Well having less threads is what I'm trying to achieve here
little eagle
And if you're machine is busy and the stack is huge, e.g. from spawning fish, then a sleep 5 can take 15 seconds to resume
It's put on the stack with a timer and the game checks every frame if the time has passed
each thread has a timestamp which when it's expected to resume
peak plover
So. Having sleep sounds so bad, because it's checked every frame
little eagle
Dunno if the scheduler sets times by itself when it thinks a script is slow or if it's reserved for sleep/uisleep
Of course it is checked every frame. The difference is that it's done in C++ land, but the PFH logic that does this similarly is pretty lightweight
I'm just telling the truth.
You do that.
You're the red one, I'm the blue one
Perfect antagonsts
We make a show for the others to enjoy.
peak plover
He's just presenting knowledge based on information he's got on the subject. No one is really never wrong or correct. Just misinformed.
little eagle
Dunno why people think a sleep command isn't checked every frame either. I mean, it's not magic, someone has to poll it.
So 2?
Idk how to read this
[spawn-ed, execVM-ed, exec-ed, execFSM-ed]
as if the first two make any difference
flares
?
There are some hard coded ones
I mean, the game intro for example is made with SQS
peak plover
Ok, a small thought. I don't want my script to run FAST. I want it to cause less stress on the machine running the script in total. Wouldn't running as many things as possible using spawn instead of everything running in one loop be better?
little eagle
~1
1 cutRsc ["SplashBohemia", "PLAIN"];
0 cutRsc ["SplashNoise","PLAIN"];
~4
if (isClass (configfile >> "CfgPatches" >> "A3_Map_Tanoabuka")) then {1 cutRsc ["SplashArma3Apex", "PLAIN"];} else {1 cutRsc ["SplashArma3", "PLAIN"];};
~4
1 cutRsc ["SplashCopyright", "PLAIN"];
~3
titleText ["", "PLAIN"];
exit
startupScript.sqs
little eagle
Dunno what you mean by "fast". Fast means less stress.
peak plover
I don't want the script in hand to be executed in the span of 5 seconds. If it would cause less strees, I wouldn't mind running it on 6 seconds instead
little eagle
He doesn't want it all in one frame, but using fast commands means exactly the same as less stress
peak plover
Yes. The least stressful way is what I am in search of
In theory. If I run everything As Fast As Possible, it's gonna cause a small hickup. This does not currently happen (atleast with [hashtag]montior 0.1).
little eagle
Measure it, nigel.
If you can't tell the difference, then it doesn't matter evidently.
peak plover
But I don't understand the concept of measuring script performance. I tried a few times. Never managed to get it to work
little eagle
You put your code into the debug console and press the code performance button. You have to use unscheduled environment for that though
peak plover
I want to build on this and add more functionality. Currently it does not have a huge problem even with 144 groups. But I need to add more features and ideas keep popping up.
little eagle
Yeah, don't do too much in one frame
The PFH thing is not a replacement for huge loops.
peak plover
For huge loops use _____ .
peak plover
๐ฆ
little eagle
The PFH would ensure that it runs every X seconds
But that frame
where it runs
everything runs
And that could end up being a slow frame
And don't make gigantic loops to begin with.
peak plover
@little eagle For caching 100 groups of units. Would it be better to have 100 loops or 1 loop ? I think for this gigantic loop is better
little eagle
Well I'd say use event handlers
Or check one group, then the next time the other
etc. etc.
have a variable that ensures that you check only one group every time
and increment that
if you end at the last group, set it back to 0
peak plover
And run that on every frame?
little eagle
That means that your code works the same with 1000 groups as it does with 1
Or every 0.1 seconds idk
depends on what you do and how large your array becomes
peak plover
That would mean for 100 groups it takes 100 frames.
That's a good idea
Cannot have above 144 groups per side
little eagle
They liftet it
peak plover
WHEN
little eagle
or soon they will
peak plover
aah, this makes more sense
little eagle
dev?
peak plover
Ok. the miricle of 64 bit is surely a great one
little eagle
Anyway, baers state machine implementation works like that
only check one item of a potentially huge list
Basically your own super simple scheduler
except less retarded already
peak plover
haha, yes ๐
You also pointed out eventhandelers ?
How often do eventhandelers usually check themselevs?
little eagle
Never
if you kill a unit, the logic that kills the unit calls all the event functions
otherwise they just rest in memory
You could make your own event handlers that use polling of very simple states
peak plover
How is this possible?
little eagle
I mean
peak plover
The creation of event handlers?
little eagle
It's easier with an example I think
jade abyss
@peak plover Prepare yourself for a 50 Pages .pdf File.

Dscha, you would read my SQF book too if I wasn't too lazy and the whole thing too unprofitable. Admit it.
jade abyss
Nah, i would watch at my own files and think: "Oh boy, why did i even started learning SQF."
peak plover
jade abyss
ah, kk
little eagle
I don't think you're doing it right when you use SQF like how it was intended.
jade abyss
You mean, i should arma it?
peak plover
I think using a custom simple scheduler with PFH would benefit ai modifications like VCOM a lot.

replace you allUnits loop with this and it will handle spawned in units
setSpeaker does not work in the frame you spawn the unit

little eagle
try
/n
or

or
<br\>
or however that's supposed to look like
If those don't work, then the answer is "no".
Btw.
I found another reason why select sucks so much.
It does all these needles out of bounds checks too
Like complain if you select +2 out of bounds or minus one
So those are more reasons why it's slower than expected
Not that that changes much.
But it essentially also reads the array size like count does.
Otherwise the error trap wouldn't work obviously.

TurnOut = "if ((_this select 1) == commander (_this select 0;) then {(_this select 0) setdamage 1;};";
You can ignore the setdamage part, it's just for testing. Pretend it runs a script :p
But it doesn't seem to work.

I have a script that on key press skips time back and forth and hints the current mission time and all works fine in MP local host, but I need to move it to a dedicated server. The working script was in initplayerlocal.sqf. Where does it need to be for all players to get the script for keybinds and see the hints?
warm lintel
Does anyone know if there's a way to simultaneously apply a scripted event or state to all instances of an object type? I've made a helo training mission for a few guys in my team & have a pattern of the portable helipad lights marking out LZs they can try & land in. I'd like to make them blink in a pattern rather than just all at once, I was thinking I'd disable simulation on the outer ring of lights then reenable it by script after a half a second from mission start or something. Is there a command vaguely like "enablesimulation false for each {CLASSNAME}" or something along those lines?
little eagle
@wispy patio You cannot use a semi-colon inside parenthesis. Syntax error.here: (_this select 0;) Check the RPT and use -showScriptErrors
@broken mural initPlayerLocal.sqf ...
@warm lintel It is not, except if you use CBA which then it totally is.

And you are sure, that you open up the right hatch?

// Noch nicht in CBA darum hier!
TurnIn = "if((_this select 2) isEqualTo [0] ) then {(_this select 0) animate ['open_hatch', 0]};";
TurnOut = "if((_this select 2) isEqualTo [0] ) then {(_this select 0) animate ['open_hatch', 1]};";
};
Or using the right slot etc

this works for me

I've tried them all as a matter of fact.

okie dokie looks like I'm stuck on a silly problem; trying to skiptime for the entire dedicated server. I got the keydown issue resolved but it's not actually skipping time.
This is what I have;
-1 remoteExec ["skipTime", 2, true]; //back 1 hour
But it should fire on all 'normal ones' right?
little eagle
"normal ones"?
little eagle
Kot, remove that JIP param, or you break it for JIP actually
wispy patio
Does it matter I didn't inherit from the base eventhandler class?
broken mural
@little eagle alright I changed that, but would that cause skiptime not to actually fire for currently connected players?
little eagle
You should, because you delete the other eventhandlers otherwise
It still would. JIP is just to retroactively execute the command on JIP clients
wispy patio
I never touched event handlers before alright, so bear with me even if I sound very silly. ๐
little eagle
but they get their start time from the server anyway
So all you'd do is move them another hour into the past
broken mural
Ah I see.
little eagle
and that for every execution, because your JIP stack grows each time you use that command
broken mural
well I dont want that lol

wispy patio
Hmm I hope not.
You had it working with non-commander slots right?
Is there anything else I need to do except adding the event handler in the config?
Because the turnout event handler should also fire generally when turning out as driver or gunner right?
warm lintel
Thanks @little eagle, you're a champ
Hah, I've just noticed the author credit on that script so I'll assume you definitely know what you're talking about...
little eagle
I think so. It's a FFV cargo slot in the Eagle actually
Like on those offroaders
Where you can "turn out" and then use the rocket launcher weapons
Those are actually hatches
Well they aren't, but they trigger turn out and that is how we animate the hatch on the Eagle IV
wispy patio
I'd say maybe the hatches on my vehicle are broken, but I wouldn't know how and the animation works.
little eagle
Because using the logic of the tank would screw up sound attenuation

Does it work for vanilla tanks though?
also
systemChat str (cameraOn addEventHandler ["TurnOut", {systemChat str _this}]);
if you do it like that, what does it print in chat?
wispy patio
It doesn't seem to do anything on vanilla tanks either.

what does the second one print in chat?
systemChat str (cameraOn addEventHandler ["TurnOut", {systemChat str _this}]);
wispy patio
That prints 0.
little eagle
But it doesn't do anything if you open and close the hatch?
little eagle
print more in chat
wispy patio
Printed 1 in a vanilla tank.
little eagle
And nothing if you turn out?
little eagle
yeah, the code increments by 1 every time
you execute it
but it should print an array without you opening the debug console again
just by turning out
[yourname, yourname, [0]]
or something like that
wispy patio
Yeah, that second little script seems to print one higher each time, whether turned out or not.
