“彩色方块连连看”游戏(续)
上期讲到相同的色块连接，链接见：Python 一步一步教你用pyglet制作“彩色方块连连看”游戏-CSDN博客
第八步
续上期，接下来要实现相邻方块的连线：
首先来进一步扩展 行列的类：
class RC:
def __init__(self, r=0, c=0):
self.r, self.c = r, c
def __repr__(self):
return f'Rc({self.r}, {self.c})'
def __and__(self, other):
return self.r == other.r and self.c == other.c
def __or__(self, other):
return self.r == other.r or self.c == other.c
def __eq__(self, other):
return self & other
def __lt__(self, other):
return self.r == other.r and self.c != other.c
def __gt__(self, other):
return self.r != other.r and self.c == other.c
def __le__(self, other):
return self.r == other.r and self.c - other.c
def __ge__(self, other):
return self.c == other.c and self.r - other.r
def __xor__(self, other):
return self < other or self > other
def __mod__(self, other):
return [RC(self.r, other.c), RC(other.r, self.c)]
def __truediv__(self, other):
return 1 if self<other and (self<=other)<0 or self>other and (self>=other)<0 else -1
def __add__(self, other):
return abs(self<=other)==1 or abs(self>=other)==1
def __sub__(self, other):
if self<other: return [RC(self.r,_) for _ in range(self.c+(self/other),other.c,self/other)]
if self>other: return [RC(_,self.c) for _ in range(self.r+(self/other),other.r,self/other)]
return []
def __mul__(self, other):
if self<other: return not any(Array[self.r+1][_+1] for _ in range(self.c+(self/other),other.c,self/other))
if self>other: return not any(Array[_+1][self.c+1] for _ in range(self.r+(self/other),other.r,self/other))
return False
由上面的类可知，self.rc*self.rc2就表示两点相邻，加时update方法中的if语句，就能实现相邻色块的连线并消去：
def update(self, event):
self.line.visible = False
clock.unschedule(self.update)
if self.last.rect.color==self.last2.rect.color and self.rc*self.rc2:
self.last.hide(); self.last2.hide()
self.array[self.rc.r][self.rc.c] = self.array[self.rc2.r][self.rc2.c] = 0
else:
self.last.box.color = self.last2.box.color = Color('WHITE').rgba
self.last, self.last2 = None, None
if game.success():
window.set_caption('彩色色块连连看——任务完成!')
