var someArray:Array = [1,2,3,4,5,6,7,8,9];

someArray.shift(); //remove first value (1)

someArray.pop();//remove final value (9)

if you type: someArray. then a list of possibilities will come up and you can see which each one does, e.g. .reverse probably reverses the array e.g. 9, 8, 7 ..etc.

yes thank you , and also it help to undo the random selection to use reverse probably

thnx prodigalmaster

No problem. Althought I don't see how reverse would undo the random selection at all.

Actually you are right , i thought when i reverse the Array i could have Random value

BUT is there a way to random the array and select item that i can remove it from my array ?

here is the code i tried to make

var someArray:Array = [1, 2, 3, 4, 5, 6, 7, 8, 9];

random_But.onRelease = function()

{

          trace(someArray.reverse());

          txt = someArray[0];

          trace("1st element   "    + someArray[0]);

          someArray.shift();//remove first value (1)

          //trace(someArray.length);

          if (someArray.length <= 1)

          {

                    this.enabled = false;

          }

};

i appreciate your Help

Make a variable and give it a random value with Math.round(Math.random()*randomNumber); or to simplify just use random(randomNumber).

Then remove a value from someArray using that variable.

A quick google search showed that what you need is splice:

someArray.splice(randomNumber,1); //index of value in array, count of values to delete e.g. if it was 2 then it would deleted the value in the index and the next

Therefore:

var randomNumber = random(someArray.length);

var someArray:Array = [1, 2, 3, 4, 5, 6, 7, 8, 9];

random_But.onRelease = function() {

someArray.splice(randomNumber, 1);//removes 1 random element

  /*

txt = someArray[0];

          if (someArray.length <= 1)

          {

                    this.enabled = false;

          }

*/ //??

randomNumber = random(someArray.length);

};
