Pygame keyboard event produces double chars












0















In a python program the keyboard is used for enter text in a screenbox. If the user types a bit faster, sometimes the characters get doubled. That means, the user types in “hello”, but on the screen is shown “hhellloo”. It seems, that the keydown-event produces repeating keys, so i have tested out different options in the pygame.key.set_repeat(0, 500) command, but nothing has changed. The issue is there under Python2 and Python3 and I'm using Fedora Linux in the latest version.



import pygame
for event in pygame.event.get():
if event.type == pygame.KEYDOWN:
print(event.key)


I know, keyboard events are a bit difficult to handle. In C++/SFML there is an option like



if (event.type == sf::Event::TextEntered)


to request explicit textinput, which works great. Can i get a working keyboard input in Python with pygame too?



framerate
The problem can be delimit, it is only there on low framerates. That means, if the game loop runs with 10 frames per second, a single keypress generates multiple keyboard events, while on a framerate above 30 fps the keyboard input works great. That means, no repeating keys are there. I have no idea what the reason is, but i want to run the game in low framerate and get also an accurate input behavior.



set_repeat
Nice hint that the problem is located within set_repeat. In my setup, this command doesn't work like expected. If I remove the command nothing changes. But it should. According to the definition the “set_repeat” statement controls if a key gets printed twice or not.

  • If you completely remove the set_repeat() call, does that change anything?
