Splitting String Into Array

Question

Hello,

I have string variable that holds a load of text, and I am trying to split it.

The string is basically player names, and player scores, it is displayed like this:

"player-score player-score player-score" --> "oliver-10 alex-20 tom-45"

And I want to break it out into arrays.

This is what I have so far (Start Function):

 var playerEntries : String[];
 var playerData : String[];
 var playerNamePull : String;
 var playerScorePull : int;
 
 playerEntries = formText.Split("\n"[0]);
 
 for(var entry : String in playerEntries){
     playerData = entry.Split("-"[0]);
    playerNamePull = playerData[0];
    playerScorePull = System.Convert.ToInt32(playerData[1]);
 }

Now, the playerEntries array works fine:

oliver-10

alex-20

tom-45

But nothing in the 'for' works - what am I doing wrong?

I'm trying to get it like this:

playerNamePull (string array) :

oliver

alex

tom

playerScorePull (int array) :

10

20

45

Thanks

If you want the result to be an array you have to use arrays... :D

 var playerEntries : String[];
 var playerData : String[];
 var playerNamePull : String[];  // They are arrays now !
 var playerScorePull : int[];    //         ||
 
 function Start()
 {
     // Read in formText
     playerEntries = formText.Split("\n"[0]);
     playerNamePull = new String[playerEntries.Length];  // Create the arrays with the
     playerScorePull = new int[playerEntries.Length];    // same size as the playerEntries array
     
     // To work with multiple arrays we need an index, so I changed the for (each) into a "normal" for loop
     
     for(var i = 0; i < playerEntries.Length; i++){
         playerData = playerEntries[i].Split("-"[0]);
         playerNamePull[i] = playerData[0];
         playerScorePull[i] = System.Convert.ToInt32(playerData[1]);
     }
 }

Thank you so much 4 year old answer! you helped prevent me from duplicating this question for an array I needed to split into 7 more arrays :D I wish I could give you a cookie. Now I just need to apply the filter option to remove the blank element at the end of the first array haha.

Remove the [0] from inside the Split function

Now I get: No appropriate version of 'String.Split' for the argument list '(String)' was found

Hm, I just copy and pasted your code and it works fine. Does your PHP script deliver the right input?

This is the code i used to test

var playerEntries : String[];

var playerData : String[];

var playerNamePull : String;

var playerScorePull : int;

function Update() { var formText = "oliver-10\nalex-20\ntom-45";

 playerEntries = formText.Split("\n"[0]);

 for(var entry : String in playerEntries){
     playerData = entry.Split("-"[0]);
    playerNamePull = playerData[0];
    playerScorePull = System.Convert.ToInt32(playerData[1]);

    Debug.Log( playerNamePull + ": " + playerScorePull );
 }

}

$$anonymous$$y PHP works fine: I have just noticed that in my playerEntries array, I get 3 extra elements that are empty. I also want playerNamePull, and playerScorePull to be arrays if possible.

playerNamePull, and playerScorePull in the inspector appear to have nothing in it - although, it prints the names and scores
