Check if an int is equal to an array int
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.
if(myIntArray.indexOf(myInt) > -1)
That's the usual way to do it in Web javascript - I imagine it'd be the same in Unity javascript.
Unity Javascript isn't at all like web Javascript though, which is why it's usually referred to as Unityscript. Also built-in arrays are part of $$anonymous$$ono, specifically System.Array. So anything to do with arrays (not the built-in Unity Array class, which shouldn't be used anyway) can be looked up in the $$anonymous$$SDN docs under System.Array. There's never any need to write your own code for basic functionality like this.
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
}
