C# Programming Recursion in Candy Crush Tutorial [Part 6] flood fill algorithm

Part of a tutorial on building a candy-crush like game that demonstrates the flood fill recursive algorithm. In this video we will code the entire flood fill algorithm showing incremental steps of development.

you have an overflow error when you select a cell with the same color of currCell
so surround with an if statement, when you first call floodFill:
if
{
floodFill(button.row, button.col);
}

hello, here i made a change and when i do floodfill, i remove the same colors and remain only the button which i click. after this i want to move buttons to nearest right and have a space on the top left. but i cant move the buttons. could you give an advise?
