在那個電子產品比較匱乏的年代,小遊戲機html
仍是爲數很少的遊戲類電子產品,對小孩子更是有着不可抗拒的魔力,在當時若是哪一個小孩買了一個小遊戲機,大夥必定迅速圍上去...網絡
俄羅斯方塊做爲其中一款小遊戲,儘管規則簡單、只有黑白雙色,但其對當時遊戲玩家的影響絲絕不亞於 LOL、農藥、吃雞對如今遊戲玩家的影響,下面咱們來看一下如何用 Python 實現俄羅斯方塊這款小遊戲。app
由小方塊組成的不一樣形狀的板塊陸續從屏幕上方落下來,玩家經過調整板塊的位置和方向,使它們在屏幕底部拼出完整的一條或幾條。這些完整的橫條會隨即消失,給新落下來的板塊騰出空間,與此同時,玩家獲得分數獎勵。沒有被消除掉的方塊不斷堆積起來,一旦堆到屏幕頂端,玩家便告輸,遊戲結束。 --- 百度百科dom
首先安裝第三方模塊 PyQt5,使用 pip install PyQt5
便可。學習
➢ 遊戲主界面url
實現代碼spa
from PyQt5.QtWidgets import * from PyQt5.QtCore import * import sys class MainBoard(QFrame): msg = pyqtSignal(str) BoardWidth = 10 BoardHeight = 22 Speed = 300 def __init__(self, parent): super().__init__(parent) self.initBoard() def initBoard(self): self.timer = QBasicTimer() self.isWaitingAfterLine = False self.curX = 0 self.curY = 0 self.numLinesRemoved = 0 self.board = [] self.setFocusPolicy(Qt.StrongFocus) self.isStarted = False self.isPaused = False
效果圖以下操作系統
➢ 小板塊插件
定義小版塊的形狀3d
class ShapeForm(object): NoShape = 0 ZShape = 1 SShape = 2 LineShape = 3 TShape = 4 SquareShape = 5 LShape = 6 MirroredLShape = 7 class Shape(object): coordsTable = ( ((0, 0), (0, 0), (0, 0), (0, 0)), ((0, -1), (0, 0), (-1, 0), (-1, 1)), ((0, -1), (0, 0), (1, 0), (1, 1)), ((0, -1), (0, 0), (0, 1), (0, 2)), ((-1, 0), (0, 0), (1, 0), (0, 1)), ((0, 0), (1, 0), (0, 1), (1, 1)), ((-1, -1), (0, -1), (0, 0), (0, 1)), ((1, -1), (0, -1), (0, 0), (0, 1)) ) def __init__(self): self.coords = [[0,0] for i in range(4)] self.pieceShape = ShapeForm.NoShape self.setShape(ShapeForm.NoShape)
畫出圖形
def drawSquare(self, painter, x, y, shape): colorTable = [0x000000, 0xCC6666, 0x66CC66, 0x6666CC, 0xCCCC66, 0xCC66CC, 0x66CCCC, 0xDAAA00] color = QColor(colorTable[shape]) painter.fillRect(x + 1, y + 1, self.squareWidth() - 2, self.squareHeight() - 2, color) painter.setPen(color.lighter()) painter.drawLine(x, y + self.squareHeight() - 1, x, y) painter.drawLine(x, y, x + self.squareWidth() - 1, y) painter.setPen(color.darker()) painter.drawLine(x + 1, y + self.squareHeight() - 1, x + self.squareWidth() - 1, y + self.squareHeight() - 1) painter.drawLine(x + self.squareWidth() - 1, y + self.squareHeight() - 1, x + self.squareWidth() - 1, y + 1)
效果圖以下
➢ 按鍵事件
def keyPressEvent(self, event): if not self.isStarted or self.curPiece.shape() == ShapeForm.NoShape: super(MainBoard, self).keyPressEvent(event) return key = event.key() if key == Qt.Key_P: self.pause() return if self.isPaused: return elif key == Qt.Key_Left: self.tryMove(self.curPiece, self.curX - 1, self.curY) elif key == Qt.Key_Right: self.tryMove(self.curPiece, self.curX + 1, self.curY) elif key == Qt.Key_Down: self.tryMove(self.curPiece.rotateRight(), self.curX, self.curY) elif key == Qt.Key_Up: self.tryMove(self.curPiece.rotateLeft(), self.curX, self.curY) elif key == Qt.Key_Space: self.dropDown() elif key == Qt.Key_D: self.oneLineDown() else: super(MainBoard, self).keyPressEvent(event) 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 >= MainBoard.BoardWidth or y < 0 or y >= MainBoard.BoardHeight: return False if self.shapeAt(x, y) != ShapeForm.NoShape: return False self.curPiece = newPiece self.curX = newX self.curY = newY self.update() return True
➢ 計時器事件
def timerEvent(self, event): if event.timerId() == self.timer.timerId(): if self.isWaitingAfterLine: self.isWaitingAfterLine = False self.newPiece() else: self.oneLineDown() else: super(MainBoard, self).timerEvent(event)
➢ 開始和暫停
def start(self): if self.isPaused: return self.isStarted = True self.isWaitingAfterLine = False self.numLinesRemoved = 0 self.clearBoard() self.msg.emit(str(self.numLinesRemoved)) self.newPiece() self.timer.start(MainBoard.Speed, self) def pause(self): if not self.isStarted: return self.isPaused = not self.isPaused if self.isPaused: self.timer.stop() self.msg.emit("paused") else: self.timer.start(MainBoard.Speed, self) self.msg.emit(str(self.numLinesRemoved)) self.update()
➢ 遊戲類及初始化
class Tetris(QMainWindow): def __init__(self): super().__init__() self.initUI() def initUI(self): self.tboard = MainBoard(self) self.setCentralWidget(self.tboard) self.statusbar = self.statusBar() self.tboard.msg[str].connect(self.statusbar.showMessage) self.tboard.start() self.resize(300, 500) self.center() self.setWindowTitle('俄羅斯方塊') self.show() def center(self): screen = QDesktopWidget().screenGeometry() size = self.geometry() self.move((screen.width()-size.width())/2, (screen.height()-size.height())/2)
啓動
if __name__ == '__main__': app = QApplication([]) tetris = Tetris() sys.exit(app.exec_())
最終效果
爲了方便運行,咱們將 Python 文件打成 exe 文件,用到的插件爲 pyinstaller。
首先,安裝 pyinstaller,使用 pip install pyinstaller
便可。 安裝完成後,在文件目錄
打開命令窗口,在命令窗口執行命令 pyinstaller --onefile --nowindowed --icon="C:\Users\LE\Desktop\tetris\tetris.ico" tetris.py
便可。執行完成後,咱們到 dist 目錄下
便可找到生成的 exe 文件。
