How to show my Array in Text without Repetition using AS3? - actionscript-3

Question

var arr:Array = new Array("A","B","C")
//random number
var rand:Number = Math.floor(Math.random()*arr.length)
//my text
t1.text = arr[rand]
t2.text = arr[rand]
t3.text = arr[rand]

Answer 1

Something like
private function getRandomText():String
{
var rand:Number = Math.floor(Math.random() * arr.length);
// this will both get you the random string from the array
// and remove it from the array making sure you won't get the same text next time
var randomString:String = arr.splice(rand, 1);
return randomString;
}
t1.text = getRandomText();
t2.text = getRandomText();
t3.text = getRandomText();
Naturally, this will modify the array by removing the displayed string. So if you need to keep the array for the future use you'd need to make a copy of that and use the copy

At my opinion, you may use this kind of function.
This was quick done but I think that avoid to check everytime in a do while loop (useless and slower).
So you may easily change the code as you need it...
var choices:Vector.<String> = new <String>["A","B","C","D","E","F"];
var randomChoices:Vector.<String> = new Vector.<String>();
var choicesBackup:Vector.<String>;
function populateLetters():void{
var n: uint = Math.floor(Math.random()*choices.length);
randomChoices.push(choices[n]);
choices.splice(n,1);
}
function getDifferentLetters():Vector.<String>{
choicesBackup = choices.slice();
randomChoices = new Vector.<String>();
for(var i:uint=choices.length; i>0; i--){
populateLetters();
}
choices = choicesBackup.slice();
return randomChoices;
}
trace ("letters = " + choices + ", flush = " + getDifferentLetters());
// output : letters = A,B,C,D,E,F, flush = D,E,B,C,F,A

Answer 3

If I missed something, just let me know!
T1.text = getDifferentLetters();
etc...
Example :
var t1:TextField = new TextField();
addChild(t1);
t1.text = getDifferentLetters().toString();
t1.x = 100;
t1.y = 100;
var t2:TextField = new TextField();
addChild(t2);
t2.text = getDifferentLetters().toString();
t2.x = 100;
t2.y = 150;
var t3:TextField = new TextField();
addChild(t3);
t3.text = getDifferentLetters().toString();
t3.x = 100;
t3.y = 200;
This should work if you have a reference to your variable T1.
In your code try to use "Lowercase" for your variables and methods.
"Uppercase" for the first letter of classes and all in "uppercase" if you use a constant.
If you use only Strings in an Array, use Vector.<String> instead of Array!
trace was just an example to get the result in the output.
