Question

Hi I just learn about Arrays... After run under UNITY and clicking on the Button Array doesn't appear. Can anyone tell me what is wrong with code below?

var myCars3=["Saab","Volvo","BMW"];

function Start () {
myCars[0]="Saab";
myCars[1]="Volvo";
myCars[2]="BMW";
}

function OnGUI(){
if(GUI.Button(new Rect(10,10,100,30), "Show Array"))
 ShowArray();
}

function ShowArray(){
 for(i=0;i<myCars3.length;i++)
 GUI.Label(new Rect(10,10 +i*30, 120,30), "This is" +myCars3[i]);
}

The function ShowArray is only called the frame when the button was pressed. Also, your Start function has no effect. Try this instead:

var myCars = ["Saab","Volvo","BMW"];
var showingArray = true;

function OnGUI(){
  if(GUI.Button(new Rect(10,10,100,30), "Toggle Array"))
    showingArray = !showingArray;

  if( showingArray )
    ShowArray();
}

function ShowArray(){
 for(i=0; i < myCars.length; i++)
   GUI.Label(new Rect(10,10 +i*30, 120,30), "This is" + myCars[i]);
}

Should be myCars.Length.

thanks Mortoc ;)

@Eric5h5 - is there any semantic diffirence between length and Length? it works anyway.

That's weird, in Mono/.NET it has to be "Length". The Javascript Array class uses "length". I guess they made "length" work with .NET arrays in Unityscript.
