Multi variables

[Minal 7]

 

Good afternoon all!

I am here today because I meet a problem ...

Indeed I do not know how to retrieve in a script the content of a variable that was created in another script.

In other words I have a script 1 which has a variable _chose and in script 2 I want to recover this variable _chose.

 

Thank you for reading my few lines! and I hope you can help me ...

 

Good bye !

Just script a "set function" in script 1 which returns _chose and call the function from script 2

 

AFAIK it is necessary to use setVariable to declare _chose in script 1. Just use a smart namespace - if the varable applies to the player use namespace player

player setVariable ["_chose", 1];

In script 2 read the variable with

_chose = player getVariable "_chose";

One can't access a single function in an external script in sqf like in real programming languages

@Minal

Post the script so we can see.

Generally speaking to record a variable for other scripts to read you would,

missionNameSpace setVariable ["my_var", true];

This is a global variable available to other scripts. To read it,

current_state=missionNameSpace getVariable ["my_var", false];

Have fun!

Hi thx all,

in my init.sqf i have

_Variable = 4584;

et dans mon script.sqf I want to hint _Variable  and i don't how I can do.

 

Can you help me please ? @wogz187

@Minal,

missionNameSpace setVariable ["variable", 4584]; //in init

myVar=missionNameSpace getVariable ["variable", 0];
systemChat format ["%1", myVar]; // to hint

Have fun!

Or just assign as a global variable by omitting the underscore, which does exactly the same thing in this case if I'm not mistaken.

@target_practice,

The big difference between global variables and missionNameSpace/unit variables is when using the latter @Dedmen won't make fun of (me).

Have fun!

It also has the difference of being slower and harder to read, so there really is no real reason for it.

Local variables will only exist inside the scope(and child scopes) you created them.

You can pass the local variable to another script as parameter or, as mentioned above simply use a global variable (which might not be what you want depending on what you're trying to achieve).

You can also use setVariable/getVariable and use objects/units/groups etc. to save and retrieve  those variables.

 

I'd only use global variables as a last resort, since they can be overridden by other scripts/mods using the same variable names.

 

Cheers

Which is why you use your own unique tag for every global variable.
