问题 Every pygame has a game loop that looks like this: while running: for event in pygame.event.get(): if event.type == pygame.QUIT: running = False pygame.display.flip() print("tick " + str(pygame.time.get_ticks())) clock.tick(1) According to the api for get_ticks() : Returns the number of millisconds since pygame.init() was called. Before pygame is initialized this will always be 0. But clock.tick() : This method should be called once per frame. It will compute how many . milliseconds have

问题 I am working through a tutorial. The tutorial can be found here https://inventwithpython.com/makinggames.pdf The main script i am referring to can be found here https://inventwithpython.com/memorypuzzle.py There is a bug in this program that I have been trying to resolve for days. In the main game loop ` while True: # main game loop mouseClicked = False DISPLAYSURF.fill(BGCOLOR) # drawing the window drawBoard(mainBoard, revealedBoxes) for event in pygame.event.get(): # event handling loop if

问题 I want to count time in pygame, when an event occurs. Ive read something in the documentation but I dont really understand on how to do it. In the documentation you can get time in miliseconds but it starts counting when the pygame.init() is called. I want to count from 0 when the boolean is true. import pygame pygame.init() loop = True boolean = False while loop: for event in pygame.event.get(): if event.type == pygame.QUIT: pygame.quit() quit() if event.type == pygame.KEYDOWN: if event.key

问题 In my main loop I have: clock.tick_busy_loop(60) pygame.display.set_caption("fps: " + str(clock.get_fps())) However, the readout says the game is reading at 62.5fps. I then tried to input clock.tick_busy_loop(57.5) , which gave me a readout of 58.82...fps. When I set clock.tick_busy_loop(59) I get 62.5fps again. It looks like there is a threshold between 58.8fps and 62.5fps that I can't overcome here. How do I get my game to actually run at 60fps? I'm mainly looking for this kind of control
