i need have sprite 'super jump' if space bar held down. under these circumstances y velocity set -12.0 opposed -8.0 in regular jump (a tap of space bar).
the code i've written using 'pygame.key.set_repeat' works know there must superior method 1 i've arrived at? starters, have 2 nested 'if' statements :/
specific code blocks:
# player jump player_jumping = false jump_vel = 0.0 player_start_y = player.y # set key repeat pygame.key.set_repeat(50, 0) # high jump space_held = 0 super_jump = false # event loop while true: ticks = pygame.time.get_ticks() # n.o ms since pygame.init() called event in pygame.event.get(): if event.type == quit: pygame.quit() sys.exit() if event.type == keydown: if event.key == k_space , space_held <2: space_held += 1 if not player_jumping: player_jumping = true jump_vel = -8.0 elif event.key == k_space , space_held == 2: if player_jumping , not super_jump: jump_vel = -12.0 super_jump = true if event.type == keyup: if event.key == k_space: space_held = 0 super_jump = true # player jumping? if player_jumping: player.y += jump_vel jump_vel += 0.5 if player.y > player_start_y: player_jumping = false player.y = player_start_y jump_vel = 0.0 super_jump = false space_held = 0 full working code:
