Re: if error

[tbutton]

     do you intent to use option[Cell] at all?
    
    Run

I can also use filterIt. 
    
    
     Direction = random.sample( filterIt( [(if j+1 > 0 and j+1 < Size: 
some(Cell(x:j+1, y:i)) else: none(Cell)), (if i+1 > 0 and i+1 < Size: 
some(Cell(x:j, y:i+1)) else: none(Cell))], it.isSome) )
    
    Run

and I intent to use it
