that's, you want to say my code won't work the way i want? If "if" expression
can't return "nothing" when the condition is false, then my code won't work
correctly, because even it will return, for example, Cell(x:j,y:i), then
return.sample can select it and delete current (unwanted) cell.
I just wanted to shorten this code
Directions = newSeq[Cell]()
if i-1 > 0 and i-1 < Size:
Directions.add(Cell(x:j, y:i-1))
if j+1 > 0 and j+1 < Size:
Directions.add(Cell(x:j+1, y:i))
if not (j+1 > 0 and j+1 < Size) and not (i-1 > 0 and i-1 < Size):
Directions.add(Cell(x:j,y:i))
var Direction = random.sample(Directions)
Run
