【问题描述】：
我正在制作一个游戏，你是猫，你必须在太空中躲避小行星（不要问）。游戏运行得非常好，我什至实现了评分系统。但是由于某种原因，每当我停止在 pygame 窗口中移动光标（我没有在游戏窗口中左右移动鼠标）时，它都会冻结并变得非常滞后。有谁知道怎么回事！？帮助！ - 请！！
这是一个例子： https://www.youtube.com/watch?v=QJJDxZE_kbU
代码：
# Import modules and initialize
import pygame as p
import sys
import random
p.init()
# Define variables
player_movement = 0
GRAVITY = 0.25
asteroid_height = [300, 100, 400, 200]
score = 0
high_score = 0
game_font = p.font.Font('fonts/PressStart2P-Regular.ttf',20)
game_active = True
# Make some functions
def create_asteroid():
random_asteroid_pos = random.choice(asteroid_height)
new_asteroid = asteroid_surface.get_rect(midtop = (650, random_asteroid_pos))
return new_asteroid
def move(asteroids):
for asteroid in asteroids:
asteroid.centerx -= 5
return asteroids
def draw(asteroids):
for asteroid in asteroids:
sc.blit(asteroid_surface, asteroid)
def collision(asteroids):
for asteroid in asteroids:
if player_rect.colliderect(asteroid):
hit_sound.play()
return False
if player_rect.top <= -100 or player_rect.bottom >= 750:
return False
return True
def display_score(game_state):
if game_state == 'in_game':
score_surface = game_font.render(f'Score: {int(score)}',True, (255,255,255))
score_rect = score_surface.get_rect(center = (110, 30))
sc.blit(score_surface, score_rect)
elif game_state == 'game_over':
high_score_surface = game_font.render(f'High Score: {int(high_score)}',True, (255,255,255))
high_score_rect = high_score_surface.get_rect(center = (320, 370))
sc.blit(high_score_surface, high_score_rect)

if score > high_score:
high_score = score
return high_score
# Make a screen

【问题讨论】：
-
您必须将相关代码添加到问题中。怎样才能帮助您在没有看到代码的情况下找到错误？
-
这个问题很可能与Indentation 有关。您需要在应用程序循环而不是事件循环中绘制场景。
-
NateDogg 就像@Rabbid76 所说，你必须在事件循环之外绘制所有内容
-
所以我有一个游戏循环，只有在你不与小行星碰撞时才会绘制角色和小行星。我应该做一个while循环并连续绘制背景吗？我只是在游戏循环中运行后台。

非常感谢大家！现在是黄油般的光滑。 :) :) :)
