The Tetris game in wxPythonhttp://www.zetcode.com/wxpython/thetetrisgame/0 + j * self.squareWidth(),boardTop + i * self.squareHeight(), shape)The painting of the game is divided into two steps. In the first step,we draw all the shapes, or remains of the shapes, that have beendropped to the bottom of the board. All the squares are rememberdin the self.board list variable. We access it using the shapeAt()method.if self.curPiece.shape() != Tetrominoes.NoShape:for i in range(4):x = self.curX + self.curPiece.x(i)y = self.curY - self.curPiece.y(i)self.drawSquare(dc, 0 + x * self.squareWidth(),boardTop + (Board.BoardHeight - y - 1) * self.squareHeight(),self.curPiece.shape())The next step is drawing of the actual piece, that is falling down.elif keycode == wx.WXK_LEFT:self.tryMove(self.curPiece, self.curX - 1, self.curY)In the OnKeyDown() method we check for pressed keys. If wepress the left arrow key, we try to move the piece to the left. We saytry, because the piece might not be able to move.def tryMove(self, newPiece, newX, newY):for i in range(4):x = newX + newPiece.x(i)y = newY - newPiece.y(i)if x < 0 or x >= Board.BoardWidth or y < 0 or y >= Board.BoardHeight:return Falseif self.shapeAt(x, y) != Tetrominoes.NoShape:return Falseself.curPiece = newPieceself.curX = newXself.curY = newYself.Refresh()return TrueIn the tryMove() method we try to move our shapes. If the shape isat the edge of the board or is adjacent to some other piece, wereturn false. Otherwise we place the current falling piece to a newposition and return true.9 de 12 27/04/2008 1:10
The Tetris game in wxPythonhttp://www.zetcode.com/wxpython/thetetrisgame/def OnTimer(self, event):if event.GetId() == Board.ID_TIMER:if self.isWaitingAfterLine:self.isWaitingAfterLine = Falseself.newPiece()else:self.oneLineDown()else:event.Skip()In the OnTimer() method we either create a new piece, after theprevious one was dropped to the bottom, or we move a falling pieceone line down.def removeFullLines(self):numFullLines = 0rowsToRemove = []for i in range(Board.BoardHeight):n = 0for j in range(Board.BoardWidth):if not self.shapeAt(j, i) == Tetrominoes.NoShape:n = n + 1if n == 10:rowsToRemove.append(i)rowsToRemove.reverse()for m in rowsToRemove:for k in range(m, Board.BoardHeight):for l in range(Board.BoardWidth):self.setShapeAt(l, k, self.shapeAt(l, k + 1))...If the piece hits the bottom, we call the removeFullLines() method.First we find out all full lines. And we remove them. We do it bymoving all lines above the current full line to be removed one linedown. Notice, that we reverse the order of the lines to be removed.Otherwise, it would not work correctly. In our case we use a naivegravity. This means, that the pieces may be floating above emptygaps.10 de 12 27/04/2008 1:10
