为什么我不能点击滑块?

您需要将事件列表传递给 pygame_widgets.update ,但不是单个事件(另请参阅 Pygame Widgets 使命感 pygame_widget 在事件循环之外 event 没有达到你的预期,因为 事件 总是只包含队列中的最后一个事件对象,因此并非所有事件都传递给 pygame_idget :

while running:

    # get list of events
    events = pygame.event.get()
    
    # use the list of events in the event loop
    for event in events:   
        if event.type == QUIT:
            running = False
        # [...]

    # pass list of events to pygame widgets
    pygame_widgets.update(events)


    # [...]

您的代码有几个问题,这些问题可能会导致冻结问题:

多个pygame.display.set_mode()调用:您已经初始化了两个屏幕(screen和win)。你只需要一个。

事件处理:滑块需要根据事件进行更新,而且您似乎在使用pygame_widets作为滑块,但在事件循环中没有为它们处理事件。

Repeatedscreen.fill():在模型更新后,您正在用一种颜色填充屏幕,这将擦除所有内容。这意味着即使滑块在工作,你也看不到它们。

更新变量:在游戏循环之前设置ra、ri、wa和wi,但在循环中没有用这些值更新模型。

以下是您的代码的重构版本,它解决了这些问题:

import pygame
from pygame.locals import *
import pygame_widgets
from pygame_widgets import Slider, TextBox

# ... [assuming Model class and other necessary imports are above]

pygame.init()
w_width = 600
w_height = 600

screen = pygame.display.set_mode([w_width, w_height])

ra = 3
ri = 5
wa = 1
wi = 0.2

model = Model(rows,cols, ra, ri, wa, wi, 0.5)
model.drawGrid(screen, w_width, w_height)

slider_wa = Slider(screen, 40, 20, 50, 10, min=0, max=2, step=0.1)
output_wa = TextBox(screen, 5, 10, 25, 25, fontSize=15)
output_wa.disable()

# ... [other sliders and text boxes]

ra = slider_ra.getValue()
ri = slider_ri.getValue()
wa = slider_wa.getValue()
wi = slider_wi.getValue()
    
running = True

time_delay = 100
timer_event = pygame.USEREVENT + 1
pygame.time.set_timer(timer_event, time_delay )

while running:
    events = pygame.event.get()
    for event in events:
        if event.type == QUIT:
            running = False
        
        if event.type == KEYDOWN:
            if event.key == K_RIGHT:
                model.update()
                model.drawGrid(screen, w_width, w_height)
        if event.type == timer_event:
                model.update()
                model.drawGrid(screen, w_width, w_height)

        # Update the sliders and text boxes with the current event
        pygame_widgets.update(events)
    
    # Only fill the part of the screen where the model is drawn
    # screen.fill((128, 128, 128), rect=pygame.Rect(0, 50, w_width, w_height-50))
                
    output_wa.setText(str(slider_wa.getValue()))
    output_wi.setText(str(slider_wi.getValue()))
    output_ra.setText(str(slider_ra.getValue()))
    output_ri.setText(str(slider_ri.getValue()))

    pygame.display.update()

pygame.quit()
