我用 Python 2.7 做了一个简单的国际象棋游戏。我用移动命令做了一个原始输入，由parseString. 我的问题是，当我进行非法移动时，我的图形首先显示出来。
我该如何解决？这是我的代码：
from visual import *
scene.autoscale=False
scene.range = 10
scene.show_rendertime = True
scene.forward=(-1,-0.4,-1)
class Board:
'Class for chess board and pieces'
def __init__(self):
'Builds board and places pieces'
self.squares = []
for i in range(64):
self.squares.append(None)
self.makeBoard()
self.placePieces()
scene.center=(3.5,0,3.5)
def addPiece(self,x,y,piece):
self.squares[y*8+x] = piece
def movePiece(self,fx,fy,tx,ty):
'Takes pice from square fx,fy and moves to tx,ty'
'Checks if piece exists on square'
piece = self.squares[fy*8+fx]
if piece == None:
print 'eh?'
return
topiece = self.squares[ty*8+tx]
if topiece != None:
topiece.setvisible(0)
piece.move((tx,0,ty))
self.squares[ty*8+tx] = piece
self.squares[fy*8+fx] = None
def parseString(self,pMove):
'Accepts input in long algebraic ie e2e4'
'Columns are a-h, rows are 1-8'
'Bottom left square is a1 top right h9 etc'
fx = 7-(ord(pMove[0])-ord('a'))
fy = ord(pMove[1])-ord('1')
tx = 7-(ord(pMove[2])-ord('a'))
ty = ord(pMove[3])-ord('1')
self.movePiece(fx,fy,tx,ty)
def makeBoard(self):
for i in range(8):
for j in range(8):
if (i+j) % 2 == 1:
sColor = color.blue
else: sColor = color.white
box(pos=(i,-0.1,j),length=1,height=0.1,width=1,color=sColor)
def placePieces(self):
for i in range(8):
self.addPiece(i,1,Pawn((i,0,1),color.white))
self.addPiece(i,6,Pawn((i,0,6),color.red))
self.addPiece(0,0,Rook((0,0,0),color.white))
self.addPiece(7,0,Rook((7,0,0),color.white))
self.addPiece(0,7,Rook((0,0,7),color.red))
self.addPiece(7,7,Rook((7,0,7),color.red))
self.addPiece(1,0,Knight((1,0,0),color.white))
self.addPiece(6,0,Knight((6,0,0),color.white))
self.addPiece(1,7,Knight((1,0,7),color.red))
self.addPiece(6,7,Knight((6,0,7),color.red))
self.addPiece(2,0,Bishop((2,0,0),color.white))
self.addPiece(5,0,Bishop((5,0,0),color.white))
self.addPiece(2,7,Bishop((2,0,7),color.red))
self.addPiece(5,7,Bishop((5,0,7),color.red))
self.addPiece(4,0,Queen((4,0,0),color.white))
self.addPiece(4,7,Queen((4,0,7),color.red))
self.addPiece(3,0,King((3,0,0),color.white))
self.addPiece(3,7,King((3,0,7),color.red))
class Piece:
'A parent class for all the piece subclasses'
def __init__(self):
self.base = None
def move(self,newPos):
self.base.pos = newPos
#All the classes for pieces
#Simply describes how they are drawn
class Pawn(Piece):
def __init__(self,spos,sColor):
self.base = cone(pos=spos,radius=0.4,axis=(0,1,0),color=sColor)
class Rook(Piece):
def __init__(self,spos,sColor):
self.base = cylinder(pos=spos,radius=0.4,length=1,axis=(0,1,0),color=sColor)
class Knight(Piece):
def __init__(self,spos,sColor):
self.base = frame(pos=spos)
box(frame=self.base,pos=(0,0.4,0),width=0.4,length=0.8,height=0.4,axis=(0,1,0),color=sColor)
cone(frame=self.base,pos=(0,0.6,0),radius=0.2,axis=(0,1,0),color=sColor)
class Bishop(Piece):
def __init__(self,spos,sColor):
self.base = frame(pos=spos)
cylinder(frame=self.base,pos=(0,0,0),radius=0.2,length=0.8,axis=(0,1,0),color=sColor)
cone(frame=self.base,pos=(0,0.8,0),radius=0.2,axis=(0,1,0),color=sColor)
class Queen(Piece):
def __init__(self,spos,sColor):
self.base = frame(pos=spos)
cylinder(frame=self.base,pos=(0,0,0),radius=0.4,length=1.0,axis=(0,1,0),color=sColor)
sphere(frame=self.base,radius=0.4,pos=(0,1.4,0),color=sColor)
class King(Piece):
def __init__(self,spos,sColor):
self.base = frame(pos=spos)
cylinder(frame=self.base,pos=(0,0,0),radius=0.4,length=1.2,axis=(0,1,0),color=sColor)
box(frame=self.base,height=0.6,width=0.6,length=0.6,pos=(0,1.5,0),color=sColor)
thisBoard = Board()
kommando = ''
while True:
kommando = raw_input('Do your move:')
thisBoard.parseString(kommando)
我认为问题是在我完成所有 raw_inputs 之前我的 GUI 不会加载。在执行 GUI 后，我需要加载函数以进行输入。我怎样才能做到这一点？
