The first thing we will place on the stage is the game board.
The idea: We just need to draw a game board that looks like the one in the original board game. A rectangle with a series of holes will fit our needs.
The development: In connect4.fla, create a new Movie Clip symbol called board_movieclip and set it as exportable for ActionScript. Leave all other settings at their default values, just like you did in previous chapters. Then draw a rectangle with registration point at 0,0 and create the holes, doing something like this:
From the picture you can easily determine the size of the board, in pixels:
width: 60 pixels * 7 columns + 5 pixels * 2 = 430 pixels
height: 60 pixels * 6 rows + 5 pixels * 2 = 370 pixels
You are free to give your board the size and shape you want, but during this chapter I will refer to these sizes, so if you are an absolute beginner I suggest you draw the board the same way I did.
