python - making loop until key is pressed in pygame -

-

in code, want move object while key pressed , stop when key released. however, moves 1 step when keep key pressed. here sample code. have printed (x,y) values. suggestion? thanks.

x = 20 y = 20  def keydown(evt):         global x, y         if evt.type == pygame.keydown:                 if(evt.key == pygame.k_right): x += 2.0                 if(evt.key == pygame.k_left): x -= 2.0                 if(evt.key == pygame.k_up): y += 2.0                 if(evt.key == pygame.k_down): y -= 2.0         if evt.type == pygame.keyup:                 if(evt.key == pygame.k_right or evt.key == pygame.k_left): x = x                 if(evt.key == pygame.k_up or evt.key == pygame.k_down): y = y   while true:         event in pygame.event.get():                 if event.type == pygame.quit:                         pygame.quit()                         sys.exit()                  print(x, y)                 keydown(event)

ps: tried posted somewhere in forum (how can make sprite move when key held down) no success.

keys = pygame.key.get_pressed() if keys[pygame.k_right]: x += 2.0 if keys[pygame.k_left]: x -= 2.0 if keys[pygame.k_up]: y += 2.0 if keys[pygame.k_down]: y -= 2.0 

x = 20 y = 20  def keydown(evt):         global x, y         if(evt[pygame.k_right]): x += 2.0         if(evt[pygame.k_left]): x -= 2.0         if(evt[pygame.k_up]): y += 2.0         if(evt[pygame.k_down]): y -= 2.0   while true:         keys = pygame.key.get_pressed()         event = pygame.event.poll()         if event.type == pygame.quit:             pygame.quit()             sys.exit()         print(x, y)         keydown(keys)

so first off had code never doing in keydown function

if evt.type == pygame.keyup:     if(evt.key == pygame.k_right or evt.key == pygame.k_left): x = x     if(evt.key == pygame.k_up or evt.key == pygame.k_down): y = y

pygame.key.get_press() returns dictionary maps pygame.key_**** booleans. iterating through give booleans, not useful you. code wrote instead work continually getting keys pressed, , changing x , y based on whether or not keys pressed.

if have more questions feel free ask, hope helped!

if still not working please post error messages
