wxPython 俄罗斯方块游戏

俄罗斯方块游戏是有史以来最受欢迎的电脑游戏之一。最初的游戏是由俄罗斯程序员Alexey Pajitnov于 1985 年设计和编程的。从那时起，俄罗斯方块几乎可以在每个计算机平台上以多种形式出现。
俄罗斯方块被称为落块益智游戏。在这个游戏中，我们有七种不同的形状，称为四联：S 形、Z 形、T 形、L 形、线形、镜像 L 形和方形。这些形状中的每一个都由四个正方形形成。形状正在从板上掉下来。俄罗斯方块游戏的目标是移动和旋转形状，使它们尽可能适合。如果我们设法形成一行，该行就会被破坏，我们就会得分。我们玩俄罗斯方块游戏，直到我们达到顶峰。

wxPython 是一个旨在创建应用程序的工具包。还有其他一些库旨在创建计算机游戏。尽管如此，wxPython 和其他应用程序工具包可用于创建游戏。
发展历程
我们没有俄罗斯方块游戏的图像，我们使用 wxPython 中可用的绘图 API 绘制四联体。每个电脑游戏的背后，都有一个数学模型。所以它是在俄罗斯方块。
游戏背后的一些想法：
- 我们
wx.Timer用来创建一个游戏循环 - 绘制了四联体
- 形状在一个正方形的基础上移动（而不是一个像素一个像素）
- 在数学上，棋盘是一个简单的数字列表

游戏被简化了一点，以便更容易理解。它在应用程序启动后立即启动。我们可以通过按键暂停游戏p。该Space键迅速降低下落俄罗斯方块片的底部。该d键下降的一块一行。（可用于加速下落。）游戏以匀速运行，不实现加速。分数是我们删除的行数。
def __init__(self, *args, **kw):
super(Board, self).__init__(*args, **kw)Windows 用户的注意事项。如果您不能使用箭头键，请添加 style=wx.WANTS_CHARS到板构造函数中。
...
self.curX = 0
self.curY = 0
self.numLinesRemoved = 0
self.board = []
...在我们开始游戏循环之前，我们初始化一些重要的变量。的self.board变量是数字的列表从0 ... 7，它表示各种形状和在板形状的遗体的位置。
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,
0 + j * self.squareWidth(),
boardTop + i * self.squareHeight(), shape)
游戏的绘画分为两个步骤。在第一步中，我们绘制所有的形状，或已经落到板底的形状的剩余部分。所有的方块都被记住在self.board列表变量中。我们使用shapeAt()方法访问它。
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())下一步是绘制正在坠落的实际部分。
elif keycode == wx.WXK_LEFT:
self.tryMove(self.curPiece, self.curX - 1, self.curY)在OnKeyDown()方法中，我们检查按下的键。如果我们按下向左箭头键，我们会尝试将棋子向左移动。我们说尝试是因为这件作品可能无法移动。
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 False
if self.shapeAt(x, y) != Tetrominoes.NoShape:
return False
self.curPiece = newPiece
self.curX = newX
self.curY = newY
self.Refresh()
return True在该tryMove()方法中，我们尝试移动我们的形状。如果形状在棋盘的边缘或与其他棋子相邻，我们返回False；否则，我们将当前下落的棋子放到新位置并返回True。
def OnTimer(self, event):
if event.GetId() == Board.ID_TIMER:
if self.isWaitingAfterLine:
self.isWaitingAfterLine = False
self.newPiece()
else:
self.oneLineDown()
else:
event.Skip()在该OnTimer()方法中，我们要么创建一个新的棋子，在前一个棋子落到底部之后，要么我们将下落的棋子向下移动一行。
def removeFullLines(self):
numFullLines = 0
rowsToRemove = []
for i in range(Board.BoardHeight):
n = 0
for j in range(Board.BoardWidth):
if not self.shapeAt(j, i) == Tetrominoes.NoShape:
n = n + 1
if 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))
...如果碎片击中底部，我们调用该removeFullLines()方法。首先，我们找出所有完整的行并删除它们。我们通过将当前整行上方的所有行移动到下一行来实现。请注意，我们颠倒了要删除的行的顺序。否则，它将无法正常工作。在我们的例子中，我们使用了一个朴素的引力。这意味着这些碎片可能漂浮在空白间隙上方。
def newPiece(self):
self.curPiece = self.nextPiece
statusbar = self.GetParent().statusbar
self.nextPiece.setRandomShape()
self.curX = Board.BoardWidth / 2 + 1
self.curY = Board.BoardHeight - 1 + self.curPiece.minY()
if not self.tryMove(self.curPiece, self.curX, self.curY):
self.curPiece.setShape(Tetrominoes.NoShape)
self.timer.Stop()
self.isStarted = False
statusbar.SetStatusText('Game over')该newPiece()方法随机创建一个新的俄罗斯方块。如果棋子不能进入其初始位置，则游戏结束。
该Shape级扑救关于俄罗斯方块的资料片。
self.coords = [[0,0] for i in range(4)]创建时，我们创建一个空的坐标列表。该列表将保存俄罗斯方块的坐标。例如，元组 (0, -1), (0, 0), (-1, 0), (-1, -1) 表示旋转的 S 形。下图说明了形状。
图：坐标
当我们绘制当前下落的棋子时，我们在self.curX和 处绘制它self.curY position。然后我们查看坐标表并绘制所有四个正方形。

这是 wxPython 中的俄罗斯方块游戏。
