How to randomize data in unity using JavaScript

Question

I have a text file in project with some text data. Using below code I'm showing my data one line at a time when player click on a button (called NEXT).

For some reason what I want to do is make a button called "RANDOM". And when player will click on that a random line from the text file will be shown.

Here is my UnityScript Code:

#pragma strict import UnityEngine; import UnityEngine.UI; var textFile : TextAsset; var dialogLines : String []; var lineNumber : int; var uiText : Text; var canvas : Canvas; function Start () { if (textFile){ dialogLines = (textFile.text.Split("\n"[0])); } } function Update () { if (lineNumber <0){ lineNumber = 0; } var dialog : String = dialogLines[lineNumber]; uiText.text = dialog; } function Next () { var randomLine = Math.floor((Math.random() * dialogLines.length) + 1); //1-10 //if dialogLines is not strictly typed, go ahead and use dialogLines.length instead of 10 return dialogLines[randomLine]; }

You can use a function like so

function randomLine() { var randomLine = Math.floor((Math.random() * 10) + 1); //1-10 //if dialogLines is not strictly typed, go ahead and use dialogLines.length instead of 10 return dialogLines[randomLine]; }

nice, is everything working as intended or do you have any additional questions?

That's bizarre, Math is just like a default library. I just checked unityscript stuff and found you have to use this docs.unity3d.com/ScriptReference/Random.html instead of Math.random, that's kinda dumb but whatever

Since you have your file split into an array just do grab a random line number.

Math.rndRange = function ( min, max ){ if( isNaN(min) || isNaN(max) ) return NaN; return Math.round(Math.random()*(max-min)+min); }

Maybe do a floor or something instead of round. W.e you want.
