Um, I could be only guessing what are you meant to do, unless you
describe your problem in more detailed way. I.e. describe the desired
behaviour, show code which you have, and describe the current
behaviour.
well, I am working on a tutorial for youngster (thats why i need to stay
the code as easy as possible). In this game you are hunted by robots. I
could use key"7" on numeric keypad for left-up moving but seems to me,
that "4"+"8" is much more standard for them.
This solution has disadvantage that after you release one key, that the
function keyPressHandler stopped to be called by the other pressed keys.
I would have not to build moving the player in KeyPresshandler, but on
another new function that would have to read periodically "keys" and to
act afterwards....
Hmmm. Maybe you'd like to hook into Tkinter event loop, i.e. by custom
events if you don't like periodical polling.
No, that would be even more difficult. I already have a code that use
your idea:
from Tkinter import *
root = Tk()
pressedKeys=set()
def onKeyPress(event):
pressedKeys.add(event.keysym)
def onKeyRelease(event):
pressedKeys.remove(event.keysym)
def move():
print list(pressedKeys)
root.after(100,move)
root.bind("<KeyPress>", onKeyPress)
root.bind("<KeyRelease>", onKeyRelease)
root.after(100,move)
root.mainloop()
well, I thought that gui´s have such a problem already built-in - so
that i am not pressed to code it. You know, its not exactly about me -
if I do it for myself, for my program, that there is no problem, but I
need to explained it to begginners ..... And I do not want, as might be
more usual, do my module, that would cover this "insanity" (look at it
with 13-years old boy eyes ;-) ). Do you like to say me, that this is
not a standard "function" neither in tkinter, not say gtk or the others,
too?
I would expect something like this:
def onKeyTouch(event):
print (event.keysymAll)
root.bind("<KeyPress>", onKeyTouch)
and all the pressed keys are printed ....all the functions OnKeyPress,
OnKeyRelease, move, even set pressedKeys are in onKeyTouch....
