We can pause thegame by pressing the p key. The space key will drop the tetris pieceimmediately to the bottom. The d key will drop the piece one linedown. (It can be used to speed up the falling a bit.) The game goesat constant speed, no acceleration is implemented. The score is thenumber of lines, that we have removed....self.curX = 0self.curY = 0self.numLinesRemoved = 0self.board = []...Before we start the game cycle, we initialize some importantvariables. The self.board variable is a list of numbers from 0 ... 7. Itrepresents the position of various shapes and remains of the shapeson the board.for i in range(Board.BoardHeight):for j in range(Board.BoardWidth):shape = self.shapeAt(j, Board.BoardHeight - i - 1)if shape != Tetrominoes.NoShape:self.drawSquare(dc,8 de 12 27/04/2008 1:10
