PyQt5制作俄罗斯方块的思路

         近来闲来无事在学习PyQt5,再看文档看到最后的俄罗斯方块的时候百思不得其解，把程序跑起来也看不到效果因为看不到图形，所以我就自己想做一个，以下是我要分享的思路。

一、先分析以下俄罗斯方块是要在界面上显示方块所以首先我们要先画方块，我就找了划方块的例子，来自PyQt5中文教程中的绘图章节。

 1 from PyQt5.QtWidgets import QWidget,QApplication
 2 from PyQt5.QtGui import QPainter,QColor,QBrush
 3 import sys
 4 
 5 class Example(QWidget):
 6     def __init__(self):
 7         super(Example, self).__init__()
 8         self.initUI()
 9 
10     def initUI(self):
11         self.setGeometry(300,300,350,100)
12         self.setWindowTitle('Colors')
13         self.show()
14 
15     def paintEvent(self, e):
16         qp = QPainter()
17         qp.begin(self)
18         self.drawRectangles(qp)
19         qp.end()
20 
21     def drawRectangles(self,qp):
22         col = QColor(0,0,0)
23         col.setNamedColor('#d4d4d4')
24         qp.setPen(col)
25         qp.setBrush(QColor(200,0,0))
26         qp.drawRect(10,15,90,60)
27         qp.setBrush(QColor(255,80,0,160))
28         qp.drawRect(130,15,90,60)
29         qp.setBrush(QColor(25,0,90,200))
30         qp.drawRect(250,15,90,60)
31 
32 if __name__ == '__main__':
33     app = QApplication(sys.argv)
34     ex = Example()
35     sys.exit(app.exec_())

这个例子是叫我们画矩形，之后照着书上俄罗斯方块的思路，是将图形定义在列表里面，里面存了坐标点。

 1 class Shape(object):
 2     coordsTable = (((0, -1), (0, 0),
 3                     (-1, 0), (-1, 1)),
 4 
 5                    ((0, -1), (0, 0),
 6                     (1, 0), (1, 1)),
 7 
 8                    ((0, -1), (0, 0),
 9                     (0, 1), (0, 2)),
10 
11                    ((-1, 0), (0, 0),
12                     (1, 0), (0, 1)),
13 
14                    ((0, 0), (1, 0),
15                     (0, 1), (1, 1)),
16 
17                    ((-1, -1), (0, -1),
18                     (0, 0), (0, 1)),
19 
20                    ((1, -1), (0, -1),
21                     (0, 0), (0, 1)))
22 
23     def __init__(self):
24         self.coords = [[0,0] for i in range(4)]
25         self.setRandomShape()
26 
27     def shape(self):
28         return self.pieceShape
29 
30     def setShape(self, shape):
31         table = Shape.coordsTable[shape]
32         for i in range(4):
33             for j in range(2):
34                 self.coords[i][j] = table[i][j]
35         self.pieceShape = shape
36 
37     def setRandomShape(self):
38         self.setShape(random.randint(1, 6))

这个书上的解释，我也是按照这个方法定义的方块，接下来我来说我的做法，这里涉及到一点算法，用这个坐标想要在自己定义的界面上显示20*20的方块必须让他的横坐标减去0.5再乘以20，让他的纵坐标加上0.5在乘以20，这样就可以使用画矩形的方法QPaint.drawRect()画出20*20的方块，代码如下：

1  def drawRectangles(self,qp):
2         col = QColor(0,0,0)
3         col.setNamedColor('#d4d4d4')
4         qp.setPen(col)
5         qp.setBrush(QColor(200,0,0))
6         for i in self.shape.coords:
7             qp.drawRect(self.Vline*20+(i[0]-0.5)*20,self.Hline*20+(i[1]+0.5)*20,20,20)
View Code

这样就能画出方块了，但是想要方块随机发生变化，书上的代码里已经写了setRandomShape(self)函数，只需要再将类中的self.coords拿出来就可以拿到要展示的方块，那就应该把注意力放在变化上，这个需要使用到QBasicTimer类，然后写timerevent，来让方块动起来。

1         self.Speed = 1000
2         self.timer = QBasicTimer()
3         self.timer.start(self.Speed,self)    
4 
5     def timerEvent(self,event):
6         self.shape.setRandomShape()
7         self.update()
View Code

这样方块就可以随机的出现在界面上，接下来就是下掉，这里我做了格子，因为我的方块是20*20的，界面是600*800的，所以左右有30列，上下有40行，所以方块出现的位置的计算方法应该是行数乘以20加上方块的显示的像素数

qp.drawRect(self.Vline*20+(i[0]-0.5)*20,self.Hline*20+(i[1]+0.5)*20,20,20)

，我将行列定义为全局变量，通过控制全局变量来控制左右，以及下掉。代码如下：

二、接下来是根据上面的思路做出主体的俄罗斯方块。上面演示的将一个图形打印在上面，接下来我们就要涉及出整体方案，我的窗口是600*800，我规定格子是20*20的，每个格子在窗口上都可以用坐标表示，【40】【30】这样，格子的动作都是通过控制这个二维列表控制的。

图形的动作，将定义好点的图形放在二维列表里这些是根据点的坐标的特性做的。

三、我将做一个能够显示分数完整的俄罗斯方块，敬请期待。
