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
初始化过程中首先取得海龟的钢笔，接着设置窗口的大小、题目和背景。
# 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 ”)# 设置窗口的题目
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，如果有问题能够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”,

},
# B 方棋子
{
“text”: “ 車 ”,
“role”: “B”,

{
“text”: “ 馬 ”,
“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，两头有一个“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，咱们每一次点击棋子并落下过程中，后盾会显示咱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: 背景色彩
textcolor: 落子色彩
“””
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
当咱们点击棋子时会触发相应的工夫，如上图所示，比方当咱们点击“卒”时，它会显示咱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(“ 发现指标：”, 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()
