Pygame让游戏因延迟而无法玩

Question

我正在制作一款你只需点击圆圈的游戏，当我注意到游戏有时真的会延迟时，我才开始工作。它不会产生新的头寸。这是我的代码:

import pygame
from pygame.font import SysFont
from pygame.display import flip
from random import randint, choice
# Bools
r = True
title = True
game = False
# Floats
# Ints
points = 0
deletewhat = [True, False]
# Strings
# Lists
spots = []
pointchoice = [1,1,1,2]
# Colors
WHITE = (255,255,255)
BLACK = (0,0,0)
RED = (255,0,0)
YELLOW = (255,255,0)
GRAY = (20,20,20)
# Pygame init
pygame.init()
pygame.font.init()
# Pygame userevents
delete = pygame.USEREVENT
# Pygame timers
pygame.time.set_timer(delete, 1000)
# Pygame Fonts
titlefont = SysFont("Arial", 70)
headfont = SysFont("Arial", 20)
startfont = SysFont("Arial", 80)
pointsfont = SysFont("Arial", 25)
# Pygame font one-time render
titletext = titlefont.render("The Spot Spotter", False, BLACK)
headtext = headfont.render("Click the spots and earn points!", False, BLACK)
starttext = startfont.render("START", False, RED)
# Other Pygame things
screen = pygame.display.set_mode((900,750))
class Spot:
def __init__(self, x, y, points):
global WHITE, GRAY
self.x = x
self.y = y
self.points = points
if self.points == 1:
self.spotcolor = WHITE
else:
self.spotcolor = GRAY
def draw(self):
pygame.draw.ellipse(screen, self.spotcolor, (self.x, self.y, 50,50))
def get_pos(self):
return self.x, self.y
def get_points(self):
return self.points
spot = Spot
while r:
for event in pygame.event.get():
if event.type == pygame.QUIT:
r = False
if event.type == delete and game:
deleteone = choice(deletewhat)
if deleteone:
spot1 = spot(randint(20, 880), randint(20, 600), choice(pointchoice))
spot1ready = True
spot2 = spot(randint(20, 880), randint(20, 600), choice(pointchoice))
spot2ready = True
if event.type == pygame.MOUSEBUTTONDOWN:
mouse = pygame.mouse.get_pos()
if mouse[0] > 249 and mouse[0] < 801:
if mouse[1] > 299 and mouse[1] < 426:
if title:
title = False
game = True
try:
spot1.get_pos()
except NameError:
pass
else:
spot1pos = spot1.get_pos()
if mouse[0] > (spot1pos[0] - 1) and mouse[0] < (spot1pos[0] + 51):
if mouse[1] > (spot1pos[1] - 1) and mouse[1] < (spot1pos[1] + 51):
if spot1ready:
spot1ready = False
points += spot1.get_points()
try:
spot2.get_pos()
except NameError:
pass
else:
spot2pos = spot2.get_pos()
if mouse[0] > (spot2pos[0] - 1) and mouse[0] < (spot2pos[0] + 51):
if mouse[1] > (spot2pos[1] - 1) and mouse[1] < (spot2pos[1] + 51):
if spot2ready:
spot2ready = False
points += spot2.get_points()
if title:
screen.fill(WHITE)
screen.blit(titletext, (250, 0))
screen.blit(headtext, (350, 100))
pygame.draw.rect(screen, YELLOW, (200, 300, 550, 125)) # Start Button
screen.blit(starttext, (375, 315))
flip()
elif game:
pointstext = pointsfont.render(f"Points: {points}", False, BLACK)
screen.fill(BLACK)
pygame.draw.rect(screen, WHITE, (0, 600, 900, 150))
screen.blit(pointstext, (20, 610))
try:
spot1.draw()
except NameError:
pass
else:
spot1.draw()
try:
spot2.draw()
except NameError:
pass
else:
spot2.draw()
flip()

pygame.quit()

如果你想知道，game和title都是用来检测哪个选项卡需要呈现。如果game为真，title为假，那么游戏知道，嘿，我需要渲染游戏。

还请注意，我在pygame不是那么好。

问题出在deleteone = choice(deletewhat)行。这可能会在一行中生成多个False。

添加变量wait_delete。当delete事件发生时，递减变量。如果wait_delete为0，则设置一个新的随机值randint。

wait_delete = 1
spot = Spot
while r:
for event in pygame.event.get():
if event.type == pygame.QUIT:
r = False
if event.type == delete and game:
wait_delete -= 1
if wait_delete == 0:
wait_delete = randint(1, 3)
spot1 = spot(randint(20, 880), randint(20, 600), choice(pointchoice))
spot1ready = True
spot2 = spot(randint(20, 880), randint(20, 600), choice(pointchoice))
spot2ready = True
