array.length read only? workaround?
hello guys. Is there anyway of changing array.length through script?
I am basically trying to make a backup var for a array. The length of the array may change with deferent situations.
also I need something that works in javascript.
thanks.

You change the length of the array by creating a new one and copying the values over. (There's a Resize function for built-in arrays, but it only works directly in C#, and even then what it actually does is create a new array anyway.) If you're talking about the Javascript-specific Array class, you can add or remove elements.

As Eric mentionned. Javascript Array will initialize new element the first time you reference them, so no need to worry about size/length.
As for built-in, I usually use something like this:
var myStrings:String[] = new String[9];
function AddString(str:String){
var buffer:String[] = myStrings;
myStrings = new String[buffer.length+1];
for(i=0;i<buffer.length;i++){ myStrings[i] = buffer[i]; }
myStrings[myStrings.length-1] = str;
}
