tkinter movement object by mouse-CodePudding

I’m trying to get the object to move in the direction of the mouse, but I’m not out of line, but I must have written something wrong.

from tkinter import *

def MouseMove(event): 
    x1, y1, x2, y2 = canvas.bbox(square)
    canvas.move(square, event.x - x2, event.y - y2)


window = Tk()
window.geometry('800x600')

canvas = Canvas(window, width=50, height=50)
square = canvas.create_rectangle(10,10,20,20, fill="red")
canvas.place(x=200, y=50)

window.bind('<Motion>', MouseMove)

window.mainloop()

I need the object to move (aiming towards the cursor) within the canvas, but everything is tracked outside the canvas

I tried to solve it this way, but somehow an object in the same direction flies away fast

from tkinter import *

def MouseMove(event):
    x1,y1,x2,y2 = canvas.bbox(square) # size object
    c_x = x1 ((x2-x1)/2) # center object x 
    c_y = y1 ((y2-y1)/2) # center object y 
    pos_x = event.x # center mouse x
    pos_y = event.y # center mouse y
    del_x = 800/50 # window size difference and canvas x
    del_y = 600/50 # window size difference and canvas y
    can_x = int(event.x/del_x)# Mouse position detection in the canvas window
    can_y = int(event.y/del_y)# Mouse position detection in the canvas window

    if c_x != can_x and c_y != can_y:
        i=0
        j=0

        if c_x < can_x:
            i = -1
        elif c_x > can_x:
            i = 1
        elif c_x == can_x:
            i = 0

        if c_y < can_y:
            j = -1
        elif c_y > can_y:
            j = 1
        elif c_y == can_y:
            j = 0

        canvas.move(square, -i, -j)

window1 = Tk()
window1.title("AIEyeGod")
window1.geometry('800x600')
window1.configure(bg='#E6E6FA')

canvas = Canvas(window1, width=50, height=50, bg='#E6E6FA')
square = canvas.create_rectangle(20,20,30,30, fill="red")
canvas.place(x=200, y=50)

window1.bind('<Motion>', MouseMove)

window1.mainloop()

but the object is out of bounds for some reason
