Moving with objects in tkinter

[dan789]

Hi all, can anybody tell me, how to find out if some object is currently located at specific coordinates? Let´s consider object1 at x=100,y=100 and I want to know, if object2 is located somewhere near to this object1, let´s say up to 50px. How to write it and what´s the syntax of this? I already know that I can change coordinates by canvas.coords(object, xy) or change some parameters of that object by canvas.itemconfig(object, parameters). Thanks a lot.
