Flash Variables

[N2o)]

Just a quick question:

Can I store a function within a variable and array, so i can call it back later with it arguments.
e.g.

function func_Hiya(Name) {
trace(Name);
}
var Test = new Array(func_Hiya(),func_Lol());
Test[0]("N2o");

I assume i can ask this here.

Yes you can. You don't call the function to get the reference, though, you simply refer to its name.

[COLOR="Blue"]function[/COLOR] Test(str:[COLOR="Blue"]String[/COLOR]) {
    [COLOR="Blue"]trace[/COLOR](str)
}

Blah = [COLOR="Blue"]new Array[/COLOR](Test)
Blah[0]([COLOR="Green"]"test"[/COLOR])

Above code should (I don't have flash open at the moment) work in ActionScript 1.0 and 2.0.

In ActionScript 3.0, you can only store the reference for anonymous functions:

[COLOR="Blue"]var[/COLOR] Test:[COLOR="Blue"]Function[/COLOR] = [COLOR="Blue"]function[/COLOR] (str:[COLOR="Blue"]String[/COLOR]) {
    [COLOR="Blue"]trace[/COLOR](str)
}

[COLOR="Blue"]var[/COLOR] Blah:[COLOR="Blue"]Array[/COLOR] = [COLOR="Blue"]new Array[/COLOR](Test)
Blah[0]([COLOR="Green"]"test"[/COLOR])

Above should work in ActionScript 3.0.

Does this only work for 1 argument or could i use it for more than 1? so could func_example2(whichString,whichNumber,whichBoolean) be stored the same as the one you mentioned above.

edit: btw i'm using Actionscript 2.0

Any number of arguments should be fine.
