游戏登录界面
1.设计登录界面1.1导入需要的工具包1.2窗口显示1.3登录界面图片显示1.4 用户名设置默认值1.5标签按钮输入框显示
2.登录功能实现2.1用户数据存储2.2登录和注册2.2.1登录功能实现注册功能实现
1.设计登录界面
1.1导入需要的工具包
<code>import tkinter as tk
from PIL import Image, ImageTk
import pickle
from tkinter import messagebox
import subprocess
1.2窗口显示
window = tk.Tk()
window.title("Welcome")
window.geometry('500x600')
1.3登录界面图片显示
image = Image.open("welcome.gif")
photo = ImageTk.PhotoImage(image)
1.4 用户名设置默认值
value = "GaoYue"
entry_var = tk.StringVar(window)
entry_var.set(value)
1.5标签按钮输入框显示
label1_image = tk.Label(window,image=photo)
label1_image.place(x=10,y=10)
label2 = tk.Label(window,text='User name',width=10,height=5)code>
label2.place(x=40,y=130)
label3 = tk.Label(window,text='password',width=10,height=5)code>
label3.place(x=40,y=180)
label4 = tk.Entry(window,width=30,bd=5)
label4.place(x=140,y=210)
label5 = tk.Entry(window,textvariable=entry_var,width=30,bd=5)
label5.place(x=140,y=160)
button1 = tk.Button(window,text='Loign',width=10,command=usr_login)code>
button1.place(x=140,y=280)
button2 = tk.Button(window,text='Sign up',width=10,command=usr_sign_up)code>
button2.place(x=250,y=280)
2.登录功能实现
2.1用户数据存储
usr_name = label5.get()
usr_pwd=label4.get()
print(usr_name)
try:
with open("usrs_info.pickle",'rb') as usr_file:
print("1")
usrs_info = pickle.load(usr_file)
print(usrs_info)
except FileNotFoundError:
with open("usrs_info.pickle",'wb') as usr_file:
print("2")
usrs_info = { 'admin':'admin'}
pickle.dump(usrs_info,usr_file)
2.2登录和注册
2.2.1登录功能实现
print("ok")
print("usr_name:",usr_name)
if usr_name in usrs_info:
print("3")
if usr_pwd == usrs_info[usr_name]:
tk.messagebox.showinfo(title="Welcome",message="How are you"+usr_name)code>
tk.messagebox.showinfo(title="Game Start", message="Let's start the game!")code>
subprocess.run(["python", "井字棋.py"])
else:
tk.messagebox.showerror(message="Error,your password is wrong,try again.")code>
else:
print("4")
is_sign_up = tk.messagebox.askyesno(title="Welcome",message="You have not sign up yet.sign up today?")code>
注册功能实现
def sign_up():
nn = entry9.get()
np = entry10.get()
npf = entry11.get()
with open('usrs_info.pickle','rb') as usr_file:
exist_usr_info = pickle.load(usr_file)
if np != npf:
tk.messagebox.showerror("Error","The user has already signed up!")
elif nn in exist_usr_info:
print("已经注册过了")
tk.messagebox.showerror("Error","The user has already signed up!")
else:
exist_usr_info[nn] = np
with open("usrs_info.pickle","wb") as usr_file:
pickle.dump(exist_usr_info,usr_file)
tk.messagebox.showinfo("Welcome","You have successfully signed up!")
window.destroy()
button3 = tk.Button(window, text='Sign up', width=10,command=sign_up)code>
button3.place(x=140, y=150)
print("开始注册")
