如何在pygame窗口上显示值？

Question

我试图让我的游戏打开一个单独的窗口，显示退出主游戏后的玩家得分。 我无法弄清楚如何让文本显示s + s2的值。 到目前为止，我有：

import pygame, sys
from pygame.locals import *
pygame.init()
import time

red = (255,0,0)
green = (0,255,0)
blue = (0,0,255)
darkBlue = (0,0,128)
white = (255,255,255)
black = (0,0,0)
pink = (255,200,200)


background = pygame.image.load('background.jpg')
screen = pygame.display.set_mode((640,521),0,32)
x,y = 285, 430
m_x, m_y = 0,0
t = 0
u = 0
q = 0
e = 0
pygame.display.set_caption('Game')
s = 0
s2 = 0
while 1:
    screen.blit(background, (0,0))
    for event in pygame.event.get():
        if event.type == QUIT:
            pygame.display.set_mode((200,200),0,32)
            pygame.display.set_caption('Score')
            font = pygame.font.Font(None, 100)
            text = font.render('s + s2'), 1, white)
            screen.blit(text, (0,0))
            pygame.display.update()
            time.sleep(5)
            pygame.quit()
            sys.exit()


        if event.type == KEYDOWN:
            if event.key == K_a:
                m_x = -3
                s+=1
                print (s)
            elif event.key == K_d:
                m_x = +3
                s2+=1
                print (s2)
        if event.type == KEYUP:
            if event.key == K_a:
                m_x = 0
            elif event.key == K_d:
                m_x = 0

    x+= m_x
    y+= m_y      

    ball = pygame.sprite.Sprite()
    ball.image = pygame.image.load('red_ball.png').convert()
    ball.rect = ball.image.get_rect()
    ball.image.set_colorkey((white))
    screen.blit(ball.image,(x,y))
    if x > 640:
        x = 0
    if x < 0:
        x = 640


    g_ball = pygame.sprite.Sprite()
    g_ball.image = pygame.image.load('green_ball.png').convert()
    g_ball.rect = g_ball.image.get_rect()
    g_ball.image.set_colorkey(white)
    screen.blit(g_ball.image,(50,t))
    t+=5
    if t > 521:
        t = 0

    g_ball2 = pygame.sprite.Sprite()
    g_ball2.image = pygame.image.load('green_ball.png').convert()
    g_ball.rect = g_ball.image.get_rect()
    g_ball2.image.set_colorkey(white)
    screen.blit(g_ball2.image,(350,u))
    u+=5
    if u > 521:
        u = -50

    g_ball3 = pygame.sprite.Sprite()
    g_ball3.image = pygame.image.load('green_ball.png').convert()
    g_ball3.rect = g_ball3.image.get_rect()
    g_ball3.image.set_colorkey(white)
    screen.blit(g_ball3.image,(500,q))
    q+=5
    if q > 521:
        q = -75

    g_ball4 = pygame.sprite.Sprite()
    g_ball4.image = pygame.image.load('green_ball.png').convert()
    g_ball4.rect = g_ball4.image.get_rect()
    g_ball4.image.set_colorkey(white)
    screen.blit(g_ball4.image,(200,e))
    e+=5
    if e > 521:
        e = -100


    pygame.display.update()

Pygame无法同时打开多个窗口。 这是因为底层SDL库的设计。

您最好的选择是将主窗口的某个角落作为显示此信息的“HUD”。

SDL的开发版本支持多个窗口（SDL 1.3），如果多个窗口仍然是您的理想解决方案，您可以查看Pygame的开发版本。

您还有绘制文本代码的问题。 （除了不匹配的括号外。）

font.render('s + s2'), 1, white)

这将显示文字“s + s2”，您需要做的是添加这两个值并将其转换为字符串。 请改用它。

font.render(str(s + s2), 1, white)
