Value seems to be spontaneously changing
I'm occasionally receiving a debug value of (0.0, -1.0). As you can see the list is private and there is no code within this script that changes the value. Please Help!
public class MC_Pawn : Piece
{
private List<Vector2> linearNoTakeMoves;
private List<Vector2> linearTakeMoves;
int moveDistance = 2;
private void Awake()
{
linearNoTakeMoves = new List<Vector2>();
linearNoTakeMoves.Add(new Vector2(0, 1));
linearTakeMoves = new List<Vector2>();
linearTakeMoves.Add(new Vector2(-1, 1));
linearTakeMoves.Add(new Vector2(1, 1));
}
public override int[,] GenerateLegalMoves(Board board)
{
int[,] legalMoves = new int[board.boardWidth, board.boardHeight];
legalMoves = FillArray(legalMoves);
ClearLog();
//2 space move
if (firstMove == false)
{
moveDistance = 1;
}
for (int i = 0; i < linearNoTakeMoves.Count; i++)
{
Debug.Log(linearNoTakeMoves[i]);
}
legalMoves = GenerateLinearMoves(legalMoves, board, linearNoTakeMoves, moveDistance, 3);
legalMoves = GenerateLinearMoves(legalMoves, board, linearTakeMoves, 1, 2);
legalMoves = MarkSelf(legalMoves);
return legalMoves;
}
}

Ok, I worked it out. turns out that when I pass through the list as an argument to "GenerateLinearMoves" I'm actually passing a reference to the list and not a copy of the list. So then in "GenerateLinearMoves" when I alter the values in the list it is in fact still altering the original list and not a copy that is local to the function.
