Select from Array

[bspendlove 10]

Hello!

 

I am just having some issues with such code, need someone else's eyes to tell me what I am doing wrong! xD

_posArray = [[2903.08,6022.17,6.77022],[3025.04,5973.28,10.5211]];

checkpoint1 = createVehicle ["Sign_Circle_F",[_posArray select 0],[],0,"CAN_COLLIDE"];
//Also tried: createVehicle ["Sign_Circle_F",_posArray select 0,[],0,"CAN_COLLIDE"];

I was inputting all the co-ordinates for my checkpoints like such:

checkpoint3 = createVehicle ["Sign_Circle_F",[3114.27,5916.77,7.38084],[],0,"CAN_COLLIDE"];

But I feel having the co-ordinates in an array would be much neater.

 

I've tried:

_posArray = [[2903.08,6022.17,6.77022],[3025.04,5973.28,10.5211]];
_pos1 = _posArray select 0; // I've also tried _pos1 = [_posArray select 0];

checkpoint1 = createVehicle ["Sign_Circle_F",_pos1,[],0,"CAN_COLLIDE"];

_posArray = [[2903.08,6022.17,6.77022],[3025.04,5973.28,10.5211]];
createVehicle ["Sign_Circle_F",_posArray select 0,[],0,"CAN_COLLIDE"];

works fine for me.

Try this:

private ["_posArray"];

_posArray = [[2903.08,6022.17],[3025.04,5973.28]];

checkpoint1 = createVehicle ["Sign_Circle_F",_posArray select 0,[],0,"CAN_COLLIDE"];

It should work.

[bspendlove 10]

Hmm, strange..

 

I tried what you put seba, but no luck.

 

Not creating the checkpoint using the: _posArray select 0

[seba1976 98]

As R3vo said, the code is working, so it should be something you haven't posted. Can you post the whole script?

[bull_a 44]

best practice would be to wrap in brackets to ensure it executes correctly

checkpoint1 = createVehicle ["Sign_Circle_F",(_posArray select 0),[],0,"CAN_COLLIDE"];

Entirely misinformation in this case. Your code looks fine as others have said.

 

Are you running with -showScriptErrors?

How/where are you executing the code?

Wrong classname maybe?

 

It's definitely not your syntax.

change

fnc_create_noe = {

 to 

fnc_create_noe = {


_posArray = [[2903.08,6022.17,6.77022],[3025.04,5973.28,10.5211]];

Many thanks, all working. :)

 

SOLVED

 

Edit-

 

Does anyone have a suggestion what I could look into to make it a bit neater/what method I should use to create my Checkpoints instead of doing: (or is this fine? I guess it would be more effective to just create a few, and move them upon entering a checkpoint?)

_checkpoint1 = createVehicle ["Sign_Circle_F",_posArray select 0,[],0,"CAN_COLLIDE"];
_checkpoint2 = createVehicle ["Sign_Circle_F",_posArray select 1,[],0,"CAN_COLLIDE"];
_checkpoint3 = createVehicle ["Sign_Circle_F",.........etc
_checkpoint4 = createVehicle ["Sign_Circle_F",.........etc
_checkpoint5 = createVehicle ["Sign_Circle_F",.........etc

Etc...?

 

Also if anyone could answer me, after setting the direction of the markers, I've heard it is useful to do something like:

_checkpoint1 setPos getPos _checkpoint1;

I've been having problems involving with the checkpoints not setting direction for other players for about 15 seconds, then it sets properly... like it doesn't Sync with all the other clients, maybe I just need to learn and read more :D

 

Thank you a ton for everyone's help. It is much appreciated !

for "_i" from 1 to _n do {call (compile (format ["_checkpoint%1 = createVehicle ['Sign_Circle_F', _posArray select %2, [], 0, 'CAN_COLLIDE'];", _i, _i - 1]))};

I can't thank you enough. You've been extremely helpful, much easier :D

[bspendlove 10]

OK now that is much better :)

 

Before I continue to add all the directions into an Array, would a similar format work for setting each direction?

[bull_a 44]

 

best practice would be to wrap in brackets to ensure it executes correctly

checkpoint1 = createVehicle ["Sign_Circle_F",(_posArray select 0),[],0,"CAN_COLLIDE"];

 

 

Entirely misinformation in this case.

 

 

How is this misinformation, it may have been the cause of the problem! The use of the brackets (in this situation) is best practice!

[SilentSpike 84]

In this situation the use of brackets makes no difference, it's misinformation to suggest that it would.

_array = [1,2];
[_array select 0] isEqualTo [(_array select 0)]; // true
_array isEqualTo [_array select 0, _array select 1]; // true

[dreadedentity 278]

Are you planning on using your _checkpoint variables at some point? I don't recommend using call compile, and if you aren't going to use the variables anyway, you may as well not even store them. However, if you do plan on using them at some point, I'd recommend an array anyway instead of a bunch of separate variables.

_signs = [];
for "_i" from 0 to _n do
{
	_obj = createVehicle ["Sign_Circle_F", _posArray select _i, [], 0, "CAN_COLLIDE"];
	_signs pushBack _obj;
};

Commas are delimiters and even if you tried to "fool" them, e.g. by writing _a = [12, (3, 45), 6, 789], it gives you a syntax error:

 

Error in expression <_a = [12, (3, 45), 6, 789]>

Error position: <, 45), 6, 789]>

Error Missing )

 

... and if it doesn't, it's a bug and should be reported.

 

Because the interpreter evaluates:

12 - next, (3 - next -> ")" missing

 

So, putting brackets there is redundant to what the comma already handles and doesn't change anything, hence there's no justification to call it "best practice" other than possible benefits to readability if that's your intention. But as I already stated here, I'd rather make spaces between commas and words to improve readability than using unnecessary brackets.
