python - Pygame - Smoother Movement -


i have added object/image on main_screen, object called cancer_cell. i'm trying here want object move smoothly. have repeatedle press on arrow keys keep moving. how make move while arrow keys pressed ?

here's code:

exitgame = false cellpos_x = 0 cellpos_y = cancer_cell.get_rect().height*2 while not exitgame:      event in pygame.event.get():         if event.type == pygame.quit:             exitgame = true             quitgame()         if event.type == pygame.keydown:             if event.key == pygame.k_left:                 cellpos_x -= 10             if event.key == pygame.k_right:                 cellpos_x += 10       gameplay_bg = pygame.image.load("/users/wolf/desktop/python/img/gameplay_bg.png").convert()     main_screen.fill(white)     main_screen.blit(gameplay_bg, [0,0])     main_screen.blit(cancer_cell, [cellpos_x, cellpos_y])     pygame.display.flip()     clock.tick(20)

someone told me try solution @ how use pygame.keydown: didn't work either. or maybe did wrong:

if event.type == pygame.keydown:     key_pressed = pygame.key.get_pressed()     if key_pressed[pygame.k_left]:         cellpos_x -= 10     if key_pressed[pygame.k_right]:         cellpos_x += 10

problem solved

i have solved problem unindenting part for loop while not exitgame:

    event in pygame.event.get():         if event.type == pygame.quit:             exitgame = true             quitgame()      key_pressed = pygame.key.get_pressed()     if key_pressed[pygame.k_left]:         cellpos_x -= 10     if key_pressed[pygame.k_right]:         cellpos_x += 10

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
