我正在尝试制作下象棋的算法。它列出了一定深度下所有可能的移动。我试图一步一步地画出可能的场景以进行测试。我使用递归函数cr_list来以深度优先的方式计算移动量。选择移动后,我更改了所涉及的各个部分的位置,并调用了draw函数来查看差异,但是画布不会更新。我使用after方法的方式似乎不正确。我也尝试过使用self.canvas.update_idletasks()方法,但是它只能运行一次,然后不再停止更改。使用ctrl + c停止程序更新后,我还将在draw函数中打印所有块的位置,它们应该是它们的位置。我使用x = input()语句停止程序以查看程序变化。
def draw(self,piece):
if self.flag:
self.canvas.delete('all')
self.flag=1
x=(800-(int(self.n)*int((660/int(self.n)))))/2
y=(800-(int(self.n)*int((660/int(self.n)))))/2
for i in range(int(self.n)):
if i%2==0:
for j in range(int(self.n)):
if j%2==0:
self.canvas.create_rectangle(x,y,x+int((660/int(self.n))),y+int((660/int(self.n))), fill='navajo white')
else:
self.canvas.create_rectangle(x,y,x+int((660/int(self.n))),y+int((660/int(self.n))), fill='saddle brown')
x+=int((660/int(self.n)))

self.canvas.create_rectangle(x,y,x+int((660/int(self.n))),y+int((660/int(self.n))), fill='saddle brown')
else:

for i in range(16):
if piece[i]!=None:
if (piece[i].pos[0]+piece[i].pos[1])%2==0:
word=piece[i].species+'_aa.ppm'
else:
word=piece[i].species+'_am.ppm'
self.img[i]=tkinter.PhotoImage(file=word)
self.canvas.create_image(x+piece[i].pos[1]*int((660/int(self.n)))+(int((660/int(self.n)))-73)/2,y+piece[i].pos[0]*int((660/int(self.n)))+(int((660/int(self.n)))-73)/2, anchor=tkinter.NW,image=self.img[i])
print(piece[i].pos)

def cr_list(self,i,lm,met,pieces):
# .....
root.after(1000,self.draw(pieces2))
self.cr_list(i2,lm,met,pieces2)
# .....
x=input()
# .....
答案 0 :(得分:0)
最后,我正常地调用了draw(),在下面我使用了self.canvas.update()并成功了。
def cr_list(self,i,lm,met,pieces):
# .....
self.draw(pieces2)
self.canvas.update()
x=input()
self.cr_list(i2,lm,met,pieces2)
# .....
