How do I find a String in an Array?

Question

humanReadableWord is declared at the top of the file and works. I can print it and I get a string. I'm able to print the array with allWords just fine. I can pull from the array. I can print this.humanReadableWord with no problem but I can't compair them for some reason... I think.

 var humanReadableWord : String;
 
 function Update(){
     var selectedLetters = GameObject.Find("SelectedLetters").GetComponent(SelectedLetters);
     var currentWordInProgress = selectedLetters.selectedLettersArray;
     this.humanReadableWord = (currentWordInProgress).Join("");
 }
 
 function ValidateWord(){
     var linkToDictionary = GameObject.Find("Dictionary").GetComponent(Dictionary);
     var allWords = linkToDictionary.dictionaryWords;
     var currentWord = ""+this.humanReadableWord;
 
     for (var i = 0; i < allWords.length; i++) {
 //   print(this.humanReadableWord);  <--Works
        if(allWords[i] == currentWord){
          print("testing!!");
        }
     }  
 }

I have a call to the function below this that I also know is working...

Use Array.Contains; you don't need to loop through the array yourself. Also I don't know what "var currentWord = ""+this.humanReadableWord;" is for since it's not doing anything...you can just use the humanReadableWord variable instead.

I tried using the Array.Contians but I always get 'Contains' is not a member of 'Array'.

You're not using the JS Array class are you? Always use built-in arrays or generic List instead.

I'm very new to programming but very dedicated. All day I've been reading about arrays and what types are what. This is what i did to create my Array. I get the results from it but I can't search it. I tried using the builtin but it acts like it doesn't recognize the builtin.

This is what I have.

var dictionaryWords = new Array(); var dictionaryTextFile : TextAsset;

function Start () {

var returnChar = "\n"[0]; this.dictionaryWords = this.dictionaryTextFile.text.Split(returnChar); }

OK, you should do this instead:

 var dictionaryWords : String[];

Was never able to get the Application to be ok with Array.Contains. Unity gripes every time. So I would still love to resolve that but now I have a new issue and maybe it's too big for this thread. So I might start a new one.

It turns out that the Array that I'm building is tacking on an extra space at the end of each word. So for instance when I run length on the word in the array and the word I'm using, I get the following.

word in array "aah" // length = 4 word user is typing "aah" // length = 3

That's why the match never happens but now I'm blown away as to why it's saying my string is one letter too long. I patched a band-aid on it by chopping it one char shorter and its working fine but it's a kluge to be sure...

Thoughts?

first try printing out the variable currentWord. And if the log is what you want then maybe the array value at i is not a match. You could also try using === which implies strictly equal
