Multidimensional arrays - editing one element within one of the arrays
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;
)
$$anonymous$$ultidimensional arrays are a bad choice. You should create a class or struct, ins$$anonymous$$d.
what is a struct? Do you have a reference for creating a class or struct in javascript?
I provided a suggestion below. Let me know if you have any questions about it.
What is the multidimensional array?Why is it a bad choice?
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 $$anonymous$$onoBehavior!
@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
