Can someone help me on this? I would like to display random characters from a
length's text and then displayed the real text.

Example: 2 or 3 seconds showing random chars and later the typewrite funcion
displayed the real text. (I know how to make the typewrite effect script)

Help will be very appreciated!

Thanks

Just created something similar (but without the typewriter effect); you'll
get the id

Create a dynamic textfield called "test_txt"
Then copy/paste the below code to the same frame that holds the textfield:

TextField.prototype.throwString = function (updatefrequency, numrepeats,
str) {
u = updatefrequency;
n = numrepeats;
// turn string into array
s = str.split ("");
// create object with properties if not existing
if (!this.Obj) {
this.Obj = new Object ();
// array for randomising string
this.Obj.chars = new Array ("a", "b", "c", "d", "e", "f", "g", "h", "i",
"j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x",
"y", "z", "!", "@", "#", "$", "%", "&", "+", "?");
// counter to compare to n
this.Obj.c = 0;
}
// function that throws random chars
this.doString = function () {
// update counter
this.Obj.c++;
// reset textfield
ns = "";
// loop through s array (representing all chars in the string)
for (i = 0; i < s.length; i++) {
// check for space
if (s[i] == " ") {
ns += " ";
} else {
x = this.Obj.chars[Math.ceil (Math.random () * this.Obj.chars.length) -
1];
ns += x;
}
// trace (i + " : " + x);
}
// trace (ns + " : " + ns.length);
this.text = ns;
if (this.Obj.c == n) {
this.text = str;
clearInterval (this.Obj.id);
}
};
this.Obj.id = setInterval (this, "doString", u);
};
// calling the prototype function
test_txt.throwString (20, 50, "laiverd is me");

Oops: little mistake.

This:
// create object with properties if not existing
if (!this.Obj) {
this.Obj = new Object ();
// array for randomising string
this.Obj.chars = new Array ("a", "b", "c", "d", "e", "f", "g", "h", "i",
"j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x",
"y", "z", "!", "@", "#", "$", "%", "&", "+", "?");
// counter to compare to n
this.Obj.c = 0;
}

Should be :

// create object with properties if not existing
if (!this.Obj) {
this.Obj = new Object ();
// array for randomising string
this.Obj.chars = new Array ("a", "b", "c", "d", "e", "f", "g", "h", "i",
"j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x",
"y", "z", "!", "@", "#", "$", "%", "&", "+", "?");
}
// counter to compare to n
this.Obj.c = 0;

Darn discovered another bug (interval wasn't cleared when the function was called quickly after another call). So for now an
improved version:

TextField.prototype.throwString = function(updatefrequency, numrepeats, str) {
u = updatefrequency;
n = numrepeats;
// turn string into array
s = str.split("");
// clear any current interval
clearInterval(this.Obj.id);
// create object with properties if not existing
if (!this.Obj) {
this.Obj = new Object();
// array for randomising string
this.Obj.chars = new Array("a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t",
"u", "v", "w", "x", "y", "z", "!", "@", "#", "$", "%", "&", "+", "?");
// counter to compare to n

}
this.Obj.c = 0;
// function that throws random chars
this.doString = function() {
// update counter
this.Obj.c++;
// reset textfield
ns = "";
// loop through s array (representing all chars in the string)
for (i = 0; i < s.length; i++) {
// check for space
if (s[i] == " ") {
ns += " ";
} else {
x = this.Obj.chars[Math.ceil(Math.random() * this.Obj.chars.length) - 1];
ns += x;
}
// trace (i + " : " + x);
}
// trace (ns + " : " + ns.length);
this.text = ns;
if (this.Obj.c == n) {
this.text = str;
clearInterval(this.Obj.id);
}
};
this.Obj.id = setInterval(this, "doString", u);
};
