Tkinter coords

[dan789]

Hi, I want to move my object (image) in tkinter, but it doesn´t work. This is what I have so far:

class Playfield:
...
def build_playfield(self):
...
self.field_icon_player = tkinter.PhotoImage(file="player.png")
...
self.canvas.create_image(j*50, i*50, anchor=NW, image=self.field_icon_player)
...

        for i in range(100):
            self.canvas.coords(self.field_icon_player, 10, 10)

How can I move with this object? Coords doesn´t work in this case. Am I doing something wrong with implementing this inside a class? Thanks.
