i want to do something if my integer is equal to any element of an int array using this variables:

var myInt : int;
var myIntArray : int[];

Just iterate over the entire array and exit with success as soon as you find a match, otherwise return no match is found. JS Arrays should also have this functionality built in.

Function FindInArray( needle : int, haystack : int[] )  : bool
{
   for each ( var item : int in haystack )
   {
      If ( needle == item )
         Return true;
   }

   Return false;
}

Mind you, this is pseudo JS, I am writing from my ipad and my knowledge of the syntax is kinda rusty - so don’t expect a copy paste to work. But this should give you a general idea.

Not sure if you are stuck using an array, but you could always use generic lists instead - gives you dynamic arrays and some easy to use functionality, including an easy way to see if the list contains something.

import System.Collections.Generic;


var myIntList : List.<int> = new List.<int>();

// Add your ints
myIntList.Add(1);
myIntList.Add(2);
myIntList.Add(3);

	
if(myIntList.Contains(myInt))
{
	// The list contains your int
}

Use IndexOf, which returns -1 if the item is not found.

if (System.Array.IndexOf (myIntArray, myInt) != -1) {
    // it's here yo
}
