need info about params/private

[dr death jm 117]

ok so basically I'm editing some code of load outs, and as I am told   call Bis_fnc_Param (is no good).

and private []; "should be"  params [];

 

but as I do so, (change code) I see no difference.

 

old

Private ["_unit","_PERIdent","_Randomise","_role","_Uniforms","_Voice","_Uniform","_Headgear","_Goggles"];
_unit=[_this,0,objNull,[ObjNull]] call Bis_fnc_Param;
_PERIdent=[_this,1,true,[true]] call Bis_fnc_Param;
_Randomise=[_this,2,true,[true]] call Bis_fnc_Param;
_role=typeOf _unit;

new

params ["_unit","_GBIdent","_Randomise","_role","_Uniform","_Uniforms","_Voice","_Headgear","_Goggles"];
_unit = param [0];
_GBIdent = param [1];
_Randomise = param [1];
_role = typeOf _unit;

why is the reason of using params to private, or the reason to need to change and not use call Bis_fnc_Param ?

I don't see the optimization. 

I'm Only asking so ill  have a better understanding  

wiki explains  params ["_one","_two","three"];

blah blah blah [1,2,3];

better yet I wish people posting in wiki would sometimes remember that no everybody understands 

and maybe should post some working code as  an example kinda like what I posted above (but with the rest of the code).

 

 

 

[davidoss 552]

params [["_unit", objNull, [objNull]], ["_PERIdent", true, [true]], ["_Randomise", true, [true]]];
private _role = typeOf _unit;

or

_this select 0 params ["_unit", objNull,[objNull]];
_this select 1 params ["_PERIdent", true, [true]];
_this select 2 params ["_Randomise", true, [true]];
private _role = typeOf _unit;

or

params ["_unit", "PERIdent", "_Randomise"];
private _role = typeOf _unit;

if you not need to predefine variables values (if not passed)

params sets your variables,

 

so when you used to do this,

_unit = param [0];
_GBIdent = param [1];
_Randomise = param [1];

You can do it simpler (and better) like this,

params ["_unit","_GBIdent","_Randomise"];

with params you dont need to make the variables private. ( private ["_var"]; )

If you use params or param, make sure to set default values and define the data types, otherwise you could simply use _this select x

k thanks guys , 

killzone_kid, gotta love ya , you sent me right to the link I had complained of , lol..

 

R3vo, yep, I'm using _this select _x or x <---?

 

jasperRap, not fully a complete answer, but I understand (i think). 

 

So Davidoss,

params ["_unit","_GBIdent","_Randomise","_role","_Uniform","_Uniforms","_Voice","_Headgear","_Goggles"];

 

you are saying should be:

 

params ["_unit","_GBIdent","_Randomise"];  no need for predrifning, "_Uniform","_Uniforms","_Voice","_Headgear","_Goggles" , I didn't post full code

but "_Uniform","_Uniforms","_Voice","_Headgear","_Goggles" are variables further down the code, so just to say and ask, if i get an undefined (error) then add it to my  params ["_unit","_GBIdent","_Randomise"]; 

 

and _role  should be  private  

 

I think  jasperRap,was saying the same thing, but not to use private,

 

I'll go thru and change code and test, Im just trying to get the code proper so the only time ill need to change it again is if there's a bis update 

that requires it

 

thanks again for your time and help..

update (about hour later)

 

so far works.

params [["_Unit", objNull, [objNull]],["_GBIdent", true, [true]],["_Randomise", true, [true]],"_role","_Uniform","_Uniforms","_Voice","_Headgear","_Goggles"];

 

private _role = typeOf _Unit;

 

 

what is the private for?

could it be  _role = typeOf _Unit;

not that im getting errors from this, 

I just wanted to know the reason 

and in case this may make a difference 

the load out is ai only not for players.

See Example 3

 

https://community.bistudio.com/wiki/private

 

Private makes the variable only available in the inner most scope, preventing it from interfering with inline functions or other code structures.

 

As a rule of thumb: It's good habit to set alle local variables private where possible. Just as extra security.

[davidoss 552]

params [
	["_Unit", objNull, [objNull]],
	["_GBIdent", true, [true]],
	["_Randomise", true, [true]]
];

private ["_role","_Uniform","_Uniforms","_Voice","_Headgear","_Goggles"];

Private variables are defined in below code of that script and as Revo said are private to  script.

You can join private variables into params array but its better to define them as private

Awesome guys , this has been a lot of help. and info.
