Pygame 计算时无响应

Question

I am currently working on a AI v AI game in pygame, I am just finishing it but one of the functions doesn't work as expected. It is something like this (this is in the pygame.event.get() loop):

if event.type == right_input:
    for e in range(100):
        data = compute_data(variables)
        re_draw_window(data)

The compute_data function can take 0.5 seconds but after something like 30 times the pygame window stops to respond and after 20 seconds when it returns to the event loop it shows the final result.

Answer 1

Th issue is causes by the loop in the loop. compute_data and re_draw_window is executed 100 times in a row. Meanwhile the window does not respond, because the events are not handled. The inner loop blocks the application, till the loop terminates.

Change the setup and initialize a variable count before the application loop and increment count in the loop.
To start the process once by an input, then add a variable start to the application and set the variable in the input event:

start = False
count = 0
while True:
    # [...]

    for event in pygame.event.get():
        # [...]

        if event.type == right_input:
            # start the process
            start = True


    if start:
        # run the process
        if count < 100:
            data = compute_data(varibals)
            re_draw_window(data)
            count += 1
