Hi Pavel,
maybe you could use Canvases as Players. Just for fun I wrote a little "Player"
class that
seems to do what you want:
from Tkinter import *
class Player(Canvas):
def __init__(self, master, x, y):
Canvas.__init__(self, master, width=12, height=12, bg='white', bd=0,
highlightthickness=0, takefocus=1)
self.master = master
self.x = x
self.y = y
self.tag = master.create_window(x, y, window=self)
self.oval = self.create_oval(0, 0, 10, 10, fill='blue')
self.bind('<FocusIn>', self._on_focus_in)
self.bind('<FocusOut>', self._on_focus_out)
for key in ('<Up>', '<Down>', '<Left>', '<Right>'):
self.bind(key, self.move)
def _on_focus_in(self, event):
self.itemconfigure(self.oval, fill='red')
def _on_focus_out(self, event):
self.itemconfigure(self.oval, fill='blue')
def coords(self, x=None, y=None):
if x == None:
x = self.x
if y == None:
y = self._y
self.x, self.y = x, y
self.master.coords(self.tag, x, y)
return x, y
def move(self, event):
x, y = self.x, self.y
k = event.keysym
if k == 'Up':
y -= 1
elif k == 'Down':
y += 1
elif k == 'Left':
x -= 1
elif k == 'Right':
x += 1
self.coords(x, y)

# test
master=Tk()
myCanvas=Canvas(master, bg="white")
player1 = Player(myCanvas, 20, 20)
player2 = Player(myCanvas, 50, 50)
myCanvas.pack()
player1.focus_set()
mainloop()
