tkinter canvas move 和 tkinter bind 达不到预期效果
初学者，变量命名不规范，请见谅。

from tkinter import Tk,Canvas
from PIL import Image,ImageTk
class Main:
def Main_gui (self):
self.root = Tk()
self.root.title('game')
self.root.state('zoomed')
self.root.update()
self.width = (self.root.winfo_width())
self.height = (self.root.winfo_height())
self.ci2x = (500)

self.image1 = ImageTk.PhotoImage(__image1)
self.image2 = ImageTk.PhotoImage(_image1)
self.c1 = Canvas(self.root,height=self.height,width=self.width,bg='green')
self.ci1 = self.c1.create_image(0,0,image=self.image1,anchor='nw')
self.ci2 = self.c1.create_image(self.ci2x,self.ci2y,image=self.image2,anchor='nw')
self.c1.pack()
self.root.bind('<Key>',self.Move)
self.root.focus_set()
self.root.mainloop()
def Move (self,event):
if (event.keysym == 'w'):
self.ci2y -= (5)
elif (event.keysym == 'a'):
self.ci2x -= (5)
elif (event.keysym == 's'):
self.ci2y += (5)
elif (event.keysym == 'd'):
self.ci2x += (5)
else:
return
self.c1.move(self.ci2,self.ci2x,self.ci2y)
_Main = Main()
_Main.Main_gui()
预期：
按w图片往上
按a图片往左
按s图片往下
按d图片往右
实际效果：
按wasd图片就会移到下图位置：
原本位置：
