Oh, I'm sorry about that, my little knowledge of non-US keyboard layouts shows.
Arrow keys could be an option. For my education what are the 2 keys to the
right of
the P then on your keyboard?
Rebinding the keys should be easy though just change them in the keypress and
keyrelease
methods.
I've updated the keybindings and you can now use [ and ] but also the cursor
keys to
control the rocket's rotation.
Thanks! It works now with the cursor keys as intended. I'm still having
trouble, but only because my game playing skills are not very good ;)
Also I've discovered that there seems to be an issue with some Tkinter
versions; it
sometimes doesn't update the screen fast enough. On OSX this problem is not
present but
it is on Python 2.7 on Windows for example. I don't know what is causing it or
how to
fix it at this time. The FPS counter in the top right of the window should
say 30,
that is when the game is updating at the intended speed.
Maybe if the system is simply too slow for your intended speed ? I see
that you are using after_idle if the delay is less than 1 ms. after_idle
performs a different task than after. I think, instead you should skip
frames, i.e. compute how many frames you are behind the clock and
advance the physics by that and draw the next frame instead. Otherwise
the delay might build up.
The drawing itself has also different speed on different system. And,
the canvas is not intended to redraw everything on each frame. Instead,
updating the objects using the coords() method is usually faster. (It
should also be easier)
