python做中国国粹——象棋

第一步：导入资源包

这次利用到的还是海龟turtle

import turtle

1

第二步：初始化

初始化过程中首先获得海龟的钢笔，接着设置窗口的大小、标题和背景。

# 初始化

pen = turtle.Pen()# 获取海龟的画笔

turtle.setup(714,800)# 设置窗口的大小

turtle.title("中国象棋")# 设置窗口的标题

turtle.bgcolor("#F4C79E")# 设置窗口的背景

pen.hideturtle()

turtle.tracer(False)

第三步：定义棋子名称与坐标

中国象棋中由車、馬、相(象)、士(仕)、炮、卒、将、帥(帅)组成，各个棋子有相应的坐标。这个可供参考，如果有问题可以自行设置相应的坐标。

array = [

# A方棋子

{

"text": "車",

"role": "A",

"pix": (-330, 369)

},

{

"text": "馬",

"role": "A",

"pix": (-247.0, 369.0)

},

{

"text": "象",

"role": "A",

"pix": (-166.0, 369.0)

},

{

"text": "士",

"role": "A",

"pix": (-86.0, 368.0)

},

{

"text": "将",

"role": "A",

"pix": (-5.0, 369.0)

},

{

"text": "士",

"role": "A",

"pix": (79.0, 368.0)

},

{

"text": "象",

"role": "A",

"pix": (159.0, 368.0)

},

{

"text": "馬",

"role": "A",

"pix": (239.0, 367.0)

},

{

"text": "車",

"role": "A",

"pix": (318.0, 369.0)

},

{

"text": "卒",

"role": "A",

"pix": (-329.0, 126.0)

},

{

"text": "卒",

"role": "A",

"pix": (-167.0, 126.0)

},

{

"text": "卒",

"role": "A",

"pix": (-6.0, 126.0)

},

{

"text": "卒",

"role": "A",

"pix": (156.0, 126.0)

},

{

"text": "卒",

"role": "A",

"pix": (319.0, 126.0)

},

{

"text": "炮",

"role": "A",

"pix": (-248.0, 209.0)

},

{

"text": "炮",

"role": "A",

"pix": (239.0, 208.0)

},

# B方棋子

{

"text": "車",

"role": "B",

"pix": (-330.0, -359.0)

},

{

"text": "馬",

"role": "B",

"pix": (-247.0, -359.0)

},

{

"text": "相",

"role": "B",

"pix": (-166.0, -359.0)

},

{

"text": "仕",

"role": "B",

"pix": (-86.0, -359.0)

},

{

"text": "帥",

"role": "B",

"pix": (-5.0, -359.0)

},

{

"text": "仕",

"role": "B",

"pix": (79.0, -359.0)

},

{

"text": "相",

"role": "B",

"pix": (159.0, -359.0)

},

{

"text": "馬",

"role": "B",

"pix": (239.0, -359.0)

},

{

"text": "車",

"role": "B",

"pix": (318.0, -359.0)

},

{

"text": "卒",

"role": "B",

"pix": (-329.0, -126.0)

},

{

"text": "卒",

"role": "B",

"pix": (-167.0, -126.0)

},

{

"text": "卒",

"role": "B",

"pix": (-6.0, -126.0)

},

{

"text": "卒",

"role": "B",

"pix": (156.0, -117.0)

},

{

"text": "卒",

"role": "B",

"pix": (319.0, -117.0)

},

{

"text": "炮",

"role": "B",

"pix": (-248.0, -199.0)

},

{

"text": "炮",

"role": "B",

"pix": (239.0, -199.0)

},

]

第四步：绘制棋盘

如下，棋盘是由网格组成，中间有一个“楚河——漢界”。

# 绘制棋盘函数

def draw():

# 绘制网格边框

pen.penup()

pen.setposition(-360, 402)

pen.pendown()

pen.color("#6E3F25")

pen.width(30)

for x in range(1,5):

if x % 2 != 0:

pen.forward(710)

else:

pen.forward(795)

pen.right(90)

# 绘制网格

pen.penup()

pen.setposition(-330, 370)

pen.width(2)

pen.pendown()

for x in range(9):

pen.forward(650)

pen.backward(650)

pen.right(90)

pen.forward(81)

pen.left(90)

pen.forward(650)

pen.left(90)

for x in range(8):

pen.forward(730)

pen.backward(730)

pen.left(90)

pen.forward(81)

pen.right(90)

pen.penup()

pen.setposition(-280, 6)

pen.pendown()

pen.pencolor("#F4C79E")

pen.right(90)

pen.width(79)

pen.forward(550)

pen.width(1)

pen.penup()

pen.setposition(-230, -25)

pen.color("#6E3F25")

pen.write("楚河", align="center", font=("Baoli TC", 50, "bold"))

pen.penup()

pen.forward(450)

pen.write("漢界", align="center", font=("Baoli TC", 50, "bold"))

pen.penup()

for x in [[-3.0, 290.0], [-4.0, -278.0]]:

pen.up()

pen.setposition(x)

pen.down()

pen.setheading(45)

pen.pendown()

pen.width(2)

pen.color("#5E3F25")

for x in range(4):

pen.forward(114)

pen.backward(114)

pen.left(90)

for x in array:

if x["role"] == "A":

chess(x["text"], x["pix"], "#A46A0C", "#2F1500")

else:

chess(x["text"], x["pix"], "#E69772", "#AB2A0E")

turtle.update()# 刷新图像

第五步：定义落子函数

如下图，我们每一次点击棋子并落下过程中，后台会显示我们点击棋子的状态和是否落子。

# 落子函数

def chess(text, pix, bgcolor, textcolor):

"""

text: 落子显示文本

pix: 落子坐标

bgcolor: 背景颜色

textcolor:落子颜色

"""

pen.penup()

pen.setposition(pix)

pen.pendown()

pen.color("#6E3F25")

pen.dot(70)

pen.color(bgcolor)

pen.dot(55)

pen.color("white")

pen.penup()

pen.setheading(270)

pen.forward(25)

pen.color(textcolor)

pen.write(text, align="center", font=("Baoli TC", 40, "bold"))

第六步：鼠标点击事件

当我们点击棋子时会触发相应的时间，如上图所示，比如当我们点击“卒”时，它会显示我们点击的是哪一方的棋子，棋子的坐标是什么。

def click(x, y):

global priChess

if priChess == {}:

for z in array:

if abs(z["pix"][0] - x) <= 35 and abs(z["pix"][1] - y) <= 35:

print("发现目标：", z)

priChess = z

pen.penup()

pen.setposition(z["pix"])

pen.color("white")

pen.penup()

pen.setheading(270)

pen.forward(25)

pen.write(z["text"], align="center", font=("Baoli TC", 40, "bold"))

break

else:

print("落子")

priChess["pix"] = (x, y)

array.append(priChess)

priChess = {}

pen.reset()

draw()
