Arrays

[AdirB 18]

Hello,

I need object names to be defined inside an array so instead of writting each one of them, I can just write the array name.

Now, I know that an array is being defined like this:

objects=["obj1", "obj2", "obj3", "obj4"]:

But I dont know how to use this array. Or where to put the array so the game will recognize this as an array.

As I said on steam it depends on ur problem. It would be a better help if u tell us what exactly u try to do.

[sarogahtyp 1108]

Assuming u have an array named _objects with a unspecified number of objects u can do the following things:

// count number of elements and decrease by one to fit the arrays index
_objcount = (count _objects) - 1;
 
//counting the index manually by a loop
while{_objcount > -1} do
{
 (_object select _objcount)  setPos [0,0,0];
 _objcount = objcount-1;
};

or this:

// automatic looping with forEach where magic variable _x represents the 
current _object
{
 _x setPos [0,0,0];
} forEach _object;

I have a trigger and in the activation of it I'm using say3d, looks like this:

lp1 say3D "alarm";
lp2 say3D "alarm";
lp3 say3D "alarm";
lp4 say3D "alarm";
lp5 say3D "alarm";
lp6 say3D "alarm";

It works but because it's being executed one after another, lp2-6 is being played in a delay.

So I thought if I define them in an array they will play all at once.

this is not an issue of not using an array. using an array will not solve the problem. thats the reason why I told u to descibe ur specific problems at the forum.

I think the problem can be solved with the usage of e.g. spawn.

but i have to work now... cant explain. maybe some other guy does it or has another solution for u.

If not ill answer later.

{

  _x say3D "alarm";

  false;

} count [lp1,lp2,lp3,lp4,lp5,lp6]

[AdirB 18]

{
  _x say3D "alarm";
  false;
} count [lp1,lp2,lp3,lp4,lp5,lp6]

Is it possible doing the same with this code line?

{
nul = [_x,"alarm"] call fn_netSay3D;
false;
} count [lp1,lp2,lp3,lp4,lp5,lp6]

[R3vo 2654]

What's fn_netSay3D and what does it do?

Seems like this function executes say3D globally, however if you use my code in a trigger it will be executed globally anyway.

{
  _x say3D "alarm";
  false;
} count [lp1,lp2,lp3,lp4,lp5,lp6]

 

Why would you use count instead of forEach?

{
  _x say3D "alarm";
} forEach [lp1, lp2, lp3, lp4, lp5, lp6];

It's technically more efficient: https://community.bistudio.com/wiki/Code_Optimisation#forEach_vs_count

[Deadfast 43]

I find it difficult to believe since the handling of the code's return value will likely outweigh the benefit gained by not having the _forEachIndex variable. Besides, for a small array this is just premature optimization.

[jshock 513]

Yea, I wasn't saying that your're not right, just the reason why some people use count over forEach, and in this instance, the return from count isn't necessary and _forEachIndex is also not necessary so truly it doesn't matter either way, and yea the data sample is small enough to not exactly matter.

Count : 0.133654 ms

Foreach: 0.252398 ms

 

Count is in this case  47,04634%  faster

Can confirm. Interesting.

 

 

The only reason (i could imagine) is: It counts the Array before executing the forEach.

 

EDIT: Ah, didn't noticed the Link posted by jshock above.

[fn_Quiksilver 1636]

The end user won't notice the difference, but in general use count instead of foreach for simple tasks, and foreach for more complex (where you're likely to require foreachindex variable. new and exciting is the apply command, can replace count in many cases.

Interesting, what exactly were you testing this with?

[R3vo 2654]

With the brand new diag_codePerformance command (debug console, dev branch)

[dscha 147]

{systemchat _x;}count ["1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1"];

{systemchat _x;}forEach ["1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1"];

try this @deadfast

(Console -> press the "speedometer"-button next to "Server Exec")

[R3vo 2654]

{systemchat _x;}count ["1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1"];

Why does that work without boolean but say3D doesn't? Both commands return nothing?

 

 

condition: Code that must return true for the tested element to be counted. The variable _x will contain the currently tested element.

I meant which data :).

[dscha 147]

{systemchat _x;}count ["1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1","1"];

From the wiki

 

Lets take "example 2"

_cnt = {_x == 4} count [1,4,4,5,5,5];
systemchat str _cnt;

systemchat shows "2"

Reason: 2x "true" (_x is a 4) / 2x CurrentCount(starting with 0) + 1 

while:

 

_cnt = {systemchat str _x} count [1,4,4,4,5,5,5];

only activates/executes the "systemchat str _x" part.

So no True/false is given. That means: "systemchat str _cnt" would be "0"

another example:

 

_cnt = {_x} count [true,true,true,true];
systemchat str _cnt;

would show "4"

Reason: 4x "true" / 4x CurrentCount(starting with 0) + 1

 

 

 

Say3D:

 

erm... looks like say3D stacks sounds and executes the following sound, when the current one is done properly.

 

[] spawn {player say3D "Alarm";}; -> 1x Sound

[] spawn {player say3D "Alarm"; player say3D "Alarm"; }; -> 2x Sound after another

[] spawn {player say3D "Alarm"; sleep 0.5; player say3D "Alarm"; }; -> 2x Sound after another (exactly as above)

[] spawn {player say3D "Alarm"; sleep 0.5; player say3D "Alarm"; sleep 0.5; player say3D "Alarm"; }; -> 3x Sound after another (exactly as above)

[] spawn {player say3D "Alarm"; player say3D "Alarm"; player say3D "Alarm"; }; -> 3x Sound after another (exactly as above)

 

 

+

{player say3D _x} count ["Alarm","AlarmCar","Alarm"];

Executes the sounds after another.

[jshock 513]

Simple way to put it, within the braces ({ }), any and all code there is executed, however, only when there is a true value returned at some point will count increment itself for its return value.
