Question

I have a multidimentional array set like the following

// 0 = G#, 1 = F#, 2 = E, 3 = D, 4 = C
// Second element is the time variable
songValues[0]  = [0,2.05];
songValues[1]  = [4,5.93];
songValues[2]  = [3,9.80];

I would like to be able to access the first element in one of the arrays (say songValues[0]) and change its value.

I already have a code which sends a message and variable to activate the following function (this function is within the same javascript as the above code)

function EditNoteType(noteValue : int){
    Debug.Log("edit note type worked! " + noteValue);
}

This works. Now I want to change the first variable in songValues[0] without changing the time variable.

(I'm not sure whether I can do this with some sort of "Shift/Pop" or not. My first attempt at this failed when I wrote:

songValues[0].Shift;

)

If you search around, you'll find that Array is generally a terrible thing; use List instead: http://msdn.microsoft.com/en-us/library/6sh2ey19.aspx

#pragma strict
import System.Collections.Generic;

enum Note {c, d, e, fSharp, gSharp}

class SongData {
    var note : Note;
    var time : float;

    function SongData(note : Note, time : float) {
       this.note = note;
       this.time = time;
    }
} var songValues : List.<SongData>;

function Reset() {
    songValues = new List.<SongData>([
       new SongData(Note.gSharp, 2.05),
       new SongData(Note.c, 5.93),
       new SongData(Note.d, 9.80)
    ]);
}

Using a class to represent song values is definitely the way to go...

thanks for your help. I will use lists next time, but since my current assignment is due on Tuesday, I will manage for the time being.

are there limitations to lists? ie things you can usually do with arrays that can't be done with lists?

mmm i get this error: Can't add script behavior SongData. The script needs to derive from MonoBehavior!

@Jessy - also, there is a bit about how you should not use constructors to initialize values. http://unity3d.com/support/documentation/ScriptReference/index.Writing_Scripts_in_Csharp.html
