[SOLVED] How do I check if {} is empty?

[Fiddi 68]

Hey,

 

I'm having trouble figuring out how to check if a "Code" type is empty. Is there a simple way to check that?

[dscha 147]

erm, do you mean that:

 

if bis_fnc_blabla is not existing -> Do that?

 

If yes, this might be helpful:

if(isNil "bis_fnc_blabla")then{dosomethingelsebecausetheotherfunctiondoesnotexists};

You mean like this?

_someCode = {};
_isEmpty = if (_someCode isEqualTo {}) then {true} else {false};

Oh, so it is so simple as to just do isEqualTo {}

 

Don't know why I didn't try it the first time.

 

Though, what is more performance friendly,

simply calling an empty code {}

or checking if it's empty and then calling it or not?

 

EDIT: Tested it with the debug console's performance tool. It's faster (and cleaner) just to call the empty code, about 0.0005 ms faster

[Guest]

Calling it may be faster. It does not inpact on performance. Calling an empty code will do nothing.

[Fiddi 68]

Yes, since I don't want anything else to happen if it's empty then it works perfectly.

 

Thanks for the help, everyone!

_isEmpty = if (_someCode isEqualTo {}) then {true} else {false};

_someCode = {};
_isEmpty = _someCode isEqualTo {};

:) Indeed. Alas, I've some tendencies to such "intellectual detours", which sometimes is funny, rarely useful, often annoying.

Out of curiosity, for what specific case would you need that?

I have a vehicle respawn function in which I can specify the initialization field of the vehicle that will be respawned, and the function is called with a parameter specifically for the init, defined in the params like so:

params [
	["_vehicle", objNull, [objNull]],
	["_delay", 10, [0]],
	["_init", {}, [{}]], // this one
	["_loadout", "", [""]],
	["_cache", false, [true]]
];

I didn't want to lose performance or have it do unpredictable things, but since it works either way...
