Pygame.mouse.get_pressed() 不会检测到我的大部分点击

Question

So this is my code :

import pygame
import pygame as pg

pygame.init()

displayWidth = 800
displayHeight = 600

### colour codes ###
bgColour = (245, 230, 255)
grey = (150, 150, 150)
darkGrey = (100, 100, 100)
darkBlack = (0,0,0)

clock = pygame.time.Clock()

mouse_clicked = False

display = pygame.display.set_mode((displayWidth, displayHeight))#sets height and width of screen
pygame.display.set_caption('Fashion!')

def screenDisplay():                                                #subroutine to display screens
    display = pygame.display.set_mode((displayWidth, displayHeight))#sets height and width of screen
    pygame.display.set_caption('Fashion!')                          #sets screen title
    display.fill(bgColour)

def text_objects(text, font):                       #font colour
    textSurface = font.render(text, True, darkBlack)
    return textSurface, textSurface.get_rect()

def textDisplay(s,t,x,y):                           #subroutine for displaying text on screen
    smallText = pygame.font.SysFont("",s)           #creates front and font size
    textSurf, textRect = text_objects(t, smallText) #inputs text
    textRect.center = (x,y)                         #centres text
    display.blit(textSurf, textRect)                #displays test


def button(msg,s,x,y,w,h,ic,ac,action=None):    #format for button
    mouse = pygame.mouse.get_pos()                  #gets mouse position (tracks cursor)
    click = pygame.mouse.get_pressed()              #gets status of mouse (tracks click)
    print(click)
    if x+w > mouse[0] > x and y+h > mouse[1] > y:   #draws rectangle for button
        pygame.draw.rect(display, ac,(x,y,w,h))     #draws rectangle after colour if mouse is on area

        if click[0] == 1 and action != None:        #performs function on click
            action()      
    else:
        pygame.draw.rect(display,ic,(x,y,w,h))      #draws rectangle initial colour if mouse isnt on area

    smallText = pygame.font.SysFont("",s)           #adds text to button
    textSurf, textRect = text_objects(msg, smallText)
    textRect.center = ( (x+(w/2)), (y+(h/2)) )
    display.blit(textSurf, textRect)


    smallText = pygame.font.SysFont("",s)           #adds text to button
    textSurf, textRect = text_objects(msg, smallText)
    textRect.center = ( (x+(w/2)), (y+(h/2)) )
    display.blit(textSurf, textRect)

def menuDisplay():
    intro = True

    while intro:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                sys.exit()
        screenDisplay()

        button("WARDROBE",60,200,100,400,100,grey,darkGrey,page)
        button("OUTFIT",  60,200,250,400,100,grey,darkGrey,page)
        button("SHOPPING",60,200,400,400,100,grey,darkGrey,page)
        button("QUIT",    40,300,530,200,50,grey,darkGrey,page) 

        pygame.display.update()
        clock.tick(30)

def page():
        intro = True

        while intro:
            for event in pygame.event.get():
                if event.type == pygame.QUIT:
                    pygame.quit()
                    sys.exit()
            screenDisplay() 

            pygame.display.update()
            clock.tick(30)


menuDisplay()

It prints the get pressed but it only returns [0,0,0] until at random times (sometimes straight away sometimes after 10 clicks sometimes after like 50 clicks) it registers [1,0,0]. it has never worked even on other computers. It didn't work when I didnt have a clock either so like that didnt change anything.

I am so sad and stressed please help 💔🙏

The issue is the call to pygame.display.set_mode in screenDisplay . Note, pygame.display.set_mode reinitialize the window and causes losing all mouse event states.
screenDisplay is called in the main application loop. It is a wast of performance and bad style to initialize the display in every frame.

Do not call screenDisplay in the main application loop, just clear the display by display.fill(bgColour) to solve the issue:

def menuDisplay():
    intro = True

    while intro:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()

        # screenDisplay() <-- DELETE
        display.fill(bgColour)

        button("WARDROBE",60,200,100,400,100,grey,darkGrey,page)
        button("OUTFIT",  60,200,250,400,100,grey,darkGrey,page)
        button("SHOPPING",60,200,400,400,100,grey,darkGrey,page)
        button("QUIT",    40,300,530,200,50,grey,darkGrey,page) 

        pygame.display.update()
        clock.tick(30)

Do the same in page()

def page():
        intro = True

        while intro:
            for event in pygame.event.get():
                if event.type == pygame.QUIT:
                    pygame.quit()
                    sys.exit()
            # screenDisplay() <-- DELETE
            display.fill(bgColour)

            pygame.display.update()
            clock.tick(30)

I changed some things and this works:

import pygame

pygame.init()

displayWidth = 800
displayHeight = 600

### colour codes ###
bgColour = (245, 230, 255)
grey = (150, 150, 150)
darkGrey = (100, 100, 100)
darkBlack = (0,0,0)

smallText = pygame.font.SysFont("",32)

display = pygame.display.set_mode((displayWidth, displayHeight))
pygame.display.set_caption('Fashion!')

def text_objects(text, font):                       #font colour
    textSurface = font.render(text, True, darkBlack)
    return textSurface, textSurface.get_rect()

def button(msg,s,x,y,w,h,ic,ac,action=None):
    mouse = pygame.mouse.get_pos()
    click = pygame.mouse.get_pressed()
    print(click)

    if x+w > mouse[0] > x and y+h > mouse[1] > y:
        pygame.draw.rect(display, ac,(x,y,w,h)) 
        if click[0] == 1 and action != None:
            action()
    else:
        pygame.draw.rect(display, ic,(x,y,w,h))

    textSurf, textRect = text_objects(msg, smallText)
    textRect.center = ( (x+(w/2)), (y+(h/2)) )
    display.blit(textSurf, textRect)

def menuDisplay():
    display.fill(bgColour)
    intro = True
    while intro:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                sys.exit()

        button("WARDROBE",60,200,100,400,100,grey,darkGrey,page)
        button("OUTFIT",  60,200,250,400,100,grey,darkGrey,page)
        button("SHOPPING",60,200,400,400,100,grey,darkGrey,page)
        button("QUIT",    40,300,530,200,50,grey,darkGrey,page) 

        pygame.display.update()

def page():
    display.fill(bgColour)
    intro = True
    while intro:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                sys.exit()

        pygame.draw.rect(display,grey,(50,50,50,50) )   
        pygame.display.update()
