Question

我想要在鼠标悬停时突出显示此矩形，并在单击时更改其颜色。我设法让它保持突出显示但点击后的颜色变化只是暂时的。我如何让它保持这种状态？

这是我的代码：

import pygame, sys
from pygame.locals import *

FPS = 30
BGCOLOR = (3, 115, 46)
BEFORECLICK = (22, 22, 106)
AFTERCLICK = (200, 200, 200)

boardWidth = 500
boardHeight = 500
rectX = 150
rectY = 150
rectWidth = 200
rectHeight = 200
myRectangle = pygame.Rect(rectX, rectY, rectWidth, rectHeight)

def main():
    global FPSCLOCK, DISPLAYSURF
    pygame.init()
    FPSCLOCK = pygame.time.Clock()
    DISPLAYSURF = pygame.display.set_mode((boardWidth, boardHeight))
    pygame.display.set_caption("Klikni, kar klikni.")

    mousex = 0
    mousey = 0

    while True:
        mouseClicked = False
        DISPLAYSURF.fill(BGCOLOR)
        pygame.draw.rect(DISPLAYSURF, BEFORECLICK, myRectangle)

        for event in pygame.event.get():
            if event.type == QUIT or (event.type == KEYUP and event.key == K_ESCAPE):
                pygame.quit()
                sys.exit()
            elif event.type == MOUSEMOTION:
                mousex, mousey = event.pos
            elif event.type == MOUSEBUTTONUP:
                mousex, mousey = event.pos
                mouseClicked = True

        mouseOver = determine_mouseOver(mousex, mousey)
        if mouseOver == True and mouseClicked == True:
            pygame.draw.rect(DISPLAYSURF, AFTERCLICK, myRectangle)
        elif mouseOver == True and mouseClicked == False:
            pygame.draw.rect(DISPLAYSURF, AFTERCLICK, myRectangle, 3)

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

def determine_mouseOver(valx, valy):
    if myRectangle.collidepoint(valx, valy):
        return True
    else:
        return False

main()

非常感谢任何帮助。谢谢！

我可能会这样做：定义一个引用当前所选按钮颜色的变量（例如button_color = BEFORECLICK），如果用户按下该按钮，只需将其更改为AFTERCLICK即可。然后你可以绘制矩形并在主循环pygame.draw.rect(DISPLAYSURF, button_color, myRectangle)中传递当前颜色。

# Current color of the button.
button_color = BEFORECLICK
mouseOver = False

while True:
    for event in pygame.event.get():
        if event.type == QUIT or (event.type == KEYUP and event.key == K_ESCAPE):
            pygame.quit()
            sys.exit()
        elif event.type == MOUSEMOTION:
            mousex, mousey = event.pos
        elif event.type == MOUSEBUTTONUP:
            if mouseOver:
                # Change the current color if button was clicked.
                button_color = AFTERCLICK

    mouseOver = determine_mouseOver(mousex, mousey)

    DISPLAYSURF.fill(BGCOLOR)
    # Just draw the rect with the current button color.
    pygame.draw.rect(DISPLAYSURF, button_color, myRectangle)

    if mouseOver:
        pygame.draw.rect(DISPLAYSURF, AFTERCLICK, myRectangle, 3)

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

PyGame单击以更改矩形的颜色
