简单的 Pygame 加载缓慢

如何解决简单的 Pygame 加载缓慢

我第一次尝试使用 Pygame 时制作了一个小井字游戏，但加载需要大约 10 秒。这是正常的吗？如果没有，我怎样才能让它更快？链接到下面的代码，如果有点乱请见谅。

import pygame,sys,time
from pygame.locals import *

moves = []
rects = []

# Initialize program
pygame.init()

# Assign FPS a value
FPS = 30
FramePerSec = pygame.time.Clock()

# Setting up color objects
BLUE  = (0,255)
RED   = (255,0)
GREEN = (0,255,0)
BLACK = (0,0)
WHITE = (255,255)

# Setup a 300x300 pixel display with caption
disPLAYSURF = pygame.display.set_mode((300,400))
disPLAYSURF.fill(WHITE)
pygame.display.set_caption("Tic Tac Toe")

def checkWin(c):
    if moves[0] == c and moves[1] == c and moves[2] == c:
        return True
    elif moves[3] == c and moves[4] == c and moves[5] == c:
        return True
    elif moves[6] == c and moves[7] == c and moves[8] == c:
        return True
    elif moves[0] == c and moves[4] == c and moves[8] == c:
        return True
    elif moves[2] == c and moves[4] == c and moves[6] == c:
        return True
    elif moves[0] == c and moves[3] == c and moves[6] == c:
        return True
    elif moves[1] == c and moves[4] == c and moves[7] == c:
        return True
    elif moves[2] == c and moves[5] == c and moves[8] == c:
        return True

    return False

def drawX(rect):
    pygame.draw.line(disPLAYSURF,RED,(rect.centerx - 25,rect.centery - 25),(rect.centerx + 25,rect.centery + 25),2)

    pygame.draw.line(disPLAYSURF,2)

    moves.pop(rects.index(rect))
    moves.insert(rects.index(rect),"X")

def drawO(rect):

            rects.append(pygame.Rect((i*100,j*100),(98,98)))
            moves.append(' ')

    pygame.draw.rect(disPLAYSURF,(0,300,0)
    myfont = pygame.font.SysFont(None,100) # use default system font,size 100
    mytext = myfont.render("X's Turn",True,WHITE)
    disPLAYSURF.blit(mytext,(25,325))
    pygame.display.update()

    gameOver = False

    count = 0

    while True:
        for event in pygame.event.get():

                    if rect.collidepoint(mouse_pos) and moves[rects.index(rect)] == ' ':
                        count += 1

                            drawX(rect)
                            if checkWin('X') == False:
                                if count == 9:
                                    mytext = myfont.render("Draw!",WHITE)
                                    gameOver = True

                                else:

                                    mytext = myfont.render("X's Turn",WHITE)
                            else:

                        pygame.display.update()

        FramePerSec.tick(FPS)

if __name__=="__main__":
    # call the main function
    main()

解决方法

我发现加载时间很长的那一行是pygame.font.SysFont(None,100)，我在这里找到了解决这个问题的方法：github.com/pygame/pygame/issues/344>

安装 XQuartz 2.7.11 后，加载速度更快
