Why is my 2D array outputting null? (all except one spot)
Hey there! My 2D array which stores where each piece is in my chess game is outputting null all except in the final foreach loop. I've tried everything... any advice?
public class BoardManager : MonoBehaviour {
int selectedX= -1, selectedY = -1;
Piece selectedPiece;
[HideInInspector] public List <Piece> activePieces;
public Piece[,] pieces;
void Start(){
this.pieces = new Piece[9, 9];
SetUpBoard ();
foreach (Piece piece in pieces) {
Debug.Log (piece); // this line outputs null
}
}
void SetUpBoard(){
//initialize piece collections
activePieces = FindObjectsOfType <Piece> ().ToList();
//set up piece references
foreach (Piece piece in activePieces) {
//map 2d array coordinates to piece coordinates
pieces [piece.x, piece.y] = piece;
if (pieces [piece.x, piece.y] != null) {
Debug.Log (pieces [piece.x, piece.y]); // this line outputs correctly
}
}
}
}

I figured it out. The X and Y values passed in were all zero. So I was just overwriting the same spot in the array over and over.
