Passing a param to a function

Question

Okay... So I am having another problem.
I have created an array and have no problem passing it to a
function as a param via set interval, as follows:
// Create a text field and import text from outside txt file
this.createTextField("aText", 1, 0, 0, 1, 1);
var a_lv:LoadVars = new LoadVars();
a_lv.onData = function(src:String):Void {
if (src != undefined) {
aText.text = src;
makeA();
} else {
aText.text = "Unable to load external file.";
a_lv.load("a.txt");
var obNum = 0;
function makeText(whichArray) {
trace(whichArray);
obNum++;
var newObject = "myOb"+obNum;
var newclip = createEmptyMovieClip(newObject, obNum);
newclip.createTextField("newText", 0, 0, 0, 100, 100).text =
whichArray[Math.round(Math.random()*whichArray.length-1)];
trace(newclip.newText.text);
newclip._x = Math.ceil(Math.random()*300);
newclip._y = Math.ceil(Math.random()*300);
function makeA() {
var a_str:String = aText.text;
var a_array:Array = a_str.split(" ");
trace(a_array);
myInterval = setInterval(_root, "makeText", 1000, a_array);
The problem is when I try to pass the param via a button:
on (keyPress "a") {
makeText(a_array);
it comes out as undefined.
What is wrong with my param pass???
I know this must be very simple, but I seem rather
addle-brained today...

Answer 1

a_array is a temporary variable that exists ony inside makeA
while its executing.
try declaring it outside makeA
var a_array:Array=[];
and inside makeA just use
a_array= a_str.split(" ");
perhaps there's other things that need attention, but that
was the first thing that jumped out at me. Also can I suggest you
use the attach Code button to post your code. It makes it easier to
read if its longer than a few lines and avoids the possibility of
errors being introduced because of formatting codes used in the
forum posts.
