Question

在我的简单程序中，我有一个开始按钮并检查事件，如果单击开始，我希望开始文本更改颜色然后我想要更改为false以便游戏开始。这种情况从未发生过，并且pygame不停地插入屏幕。我希望while循环开始，然后它将转到另一个while循环。如何检查是否单击了开始，更改文本颜色，然后在以下代码中结束while循环？

import pygame, sys
from pygame.locals import *

pygame.init()

FPS = 60  # frames per second setting
clock = pygame.time.Clock()

screen = pygame.display.set_mode((700, 800))

window_width = 540
window_height = 800

#Title screen fonts
fontObj2 = pygame.font.Font('freesansbold.ttf', 60)
start = fontObj2.render("Start", True,(255,255,255))

into=True

while into==True:
    screen.blit(start, (window_width / 2, 600))

    for event in pygame.event.get(): #Closes game
        if event.type == QUIT:
            pygame.quit()
            sys.exit()
        elif start.get_rect().collidepoint(pygame.mouse.get_pos()):
            x, y = event.pos
            if start.get_rect().collidepoint(x, y):
                start = fontObj2.render("Start", True, (192,192,192))
                into=False
        elif event.type == pygame.MOUSEBUTTONDOWN:
            x, y = event.pos
            if start.get_rect().collidepoint(x, y):
                start = fontObj2.render("Start", True, (192,192,192))
                into = False
    pygame.display.flip()
    pygame.display.update()
    clock.tick(FPS)

Answer 1

首先，你可以摆脱start.get_rect().collidepoint(pygame.mouse.get_pos())，因为你已经在event.type == pygame.MOUSEBUTTONDOWN中定义了它。

您的代码无法正常工作，因为start.get_rect()的位置并非位于屏幕上的位置。如果您打印它，您会在左上角看到<rect(0, 0, 140, 61)>这是一个矩形。

要解决此问题，您只需将其更改为start.get_rect(x=window_width / 2, y=600) #where you blit the font即可设置矩形的位置。

所以要克制：

import pygame, sys
from pygame.locals import *

pygame.init()

FPS = 60 
clock = pygame.time.Clock()

screen = pygame.display.set_mode((700, 800))

window_width = 540
window_height = 800

fontObj2 = pygame.font.Font('freesansbold.ttf', 60)
start = fontObj2.render("Start", True,(255,255,255))

into=True

while into: #Equivalent to into == True
    screen.blit(start, (window_width / 2, 600))

    for event in pygame.event.get(): 
        if event.type == QUIT:
            pygame.quit()
            sys.exit()
        #got rid of another if statement
        elif event.type == pygame.MOUSEBUTTONDOWN:
            x, y = event.pos
            if start.get_rect(x=window_width / 2, y=600).collidepoint(x, y): #changed start.get_rect
                start = fontObj2.render("Start", True, (192,192,192))
                into = False

    #same as before
    pygame.display.flip()
    pygame.display.update()
    clock.tick(FPS)

无法在pygame中启动游戏进入屏幕
