Python Tkinter在国际象棋游戏中移动一个带有位置的图像
Python Tkinter在国际象棋游戏中移动一个带有位置的图像
提问于 2021-11-04 10:27:54
我用Python和Tkinter做了一个国际象棋游戏，但我有一个很大的问题。
该片段是由矩阵生成的。但是，当一个盒子是空的，或者当我移动了一块时，我不希望(删除)这个盒子。我希望(删除)只有一件与协和或只是移动图像的一件(我不知道这是否可能)，有人帮助吗？
代码：
from tkinter import *
from PIL import Image
import math
root = Tk()
root.title("Game")
frame = Frame(root)
frame.pack()
canvas = Canvas(frame, bg="black", width=500, height=500)
canvas.pack()
background = PhotoImage(file="image/Chessboard.png")
canvas.create_image(250,250,image=background)
pion = PhotoImage(file="image/W_pion.png")
Matrixe= [["","","","","","","",""],
["","","","","","","",""],
["","","","","","","",""],
["","","","","","","",""],
["","","","","","","",""],
["","","","","","","",""],
["W_Pion","W_Pion","W_Pion","W_Pion","W_Pion","W_Pion","W_Pion","W_Pion"],
["","","","","","","",""]]
ligne=len(Matrixe)
col=len(Matrixe[0])
def actu():
for l in range(ligne):
for c in range(col):
if Matrixe[c][l] == "W_Pion":
canvas.create_image(62.5 * l + 33,62.5 * c + 33,image=pion)
actu()
#mouse input
def getorigin(eventorigin):
global Posx,Posy, i, piece
Posx = eventorigin.x
Posy = eventorigin.y
Xcase = math.ceil((Posx / 62)) - 1
Ycase = math.ceil((Posy / 62)) - 1
if Matrixe[Ycase][Xcase] != "":
global preY , preX, piece
piece = Matrixe[Ycase][Xcase]
i = 1
preY = Ycase
preX = Xcase
print(piece)
if canvas.bind("<Button-1>") and Matrixe[Ycase][Xcase] == "":
Matrixe[Ycase][Xcase] = piece
Matrixe[preY][preX] = ""
print(Matrixe[preY][preX])
actu()
canvas.bind("<Button-1>", getorigin)
root.title("Chess")
root.iconbitmap("icon.ico")
root.geometry("500x500")
root.mainloop()回答 1

这是因为在actu()中创建新的一组棋子之前，您没有删除以前的一组棋子。
创建带有标签的棋子，例如‘棋子’，然后您可以使用该标签删除旧的一组棋子：
def actu():
canvas.delete('piece') # delete old chess pieces
for l in range(ligne):
for c in range(col):
if Matrixe[c][l] == "W_Pion":
canvas.create_image(62.5*l+33, 62.5*c+33, image=pion, tag='piece')但是，更好的方法是只移动选定的片段，而不是重新创建一组片段：
def actu():
for l in range(ligne):
for c in range(col):
if Matrixe[c][l] == "W_Pion":
# replace cell content by the canvas item ID
Matrixe[c][l] = canvas.create_image(62.5*l+33, 62.5*c+33, image=pion, tag=Matrixe[c][l])
actu()
piece = None
def getorigin(eventorigin):
global preX, preY, piece
Posx = eventorigin.x
Posy = eventorigin.y
Xcase = math.ceil((Posx / 62)) - 1
Ycase = math.ceil((Posy / 62)) - 1
if Matrixe[Ycase][Xcase] != "":
# select the piece
piece = Matrixe[Ycase][Xcase]
preY = Ycase
preX = Xcase
elif piece:
# a piece is selected, so move the piece
canvas.coords(piece, Xcase*62.5+33, Ycase*62.5+33)
Matrixe[Ycase][Xcase] = piece
Matrixe[preY][preX] = ""
piece = None # deselect the piece页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
