Change A Character In A String Using Actionscript

Question

What is the opposite of String.charAt()??

If I Have a string:

var Str:String=\"Hello World\";

How do I change the 5th chara

Answer 1

you cannot set any characters. Strings in ECMAScript (including ActionScript) are immutable. One thing you can do is to construct a new string containing the desired characters, as proposed here.

However, if you plan to modify the string a lot, the best is to rather have an array of characters, that you can mutate at will. When you need to print it, you simply join it with "" as separator.
