pygame 游戏速度因电脑而异

Question

我刚刚用 pygame 完成了我的第二个 Python 游戏，但这次我遇到了一个新问题。当我在另一台电脑上尝试游戏时，游戏速度非常快，比预期的要快得多，我试图调整 FPS 但没有帮助。当我已经设置了所有设置（如移动速度和游戏 FPS）时，如何解决这个问题？为什么还会发生这种情况？

import pygame
from settings import Settings
import game_functions as gf
from ship import Ship
from pygame.sprite import Group
from game_stats import Stats
from animation import spriteSheet
from scoreboard import ScoreBoard
from button import Button

def run_game():

    pygame.init()

    icon = pygame.image.load('icons/icon.png')
    pygame.display.set_icon(icon)

    so_settings = Settings()

    screen = pygame.display.set_mode((so_settings.screen_width, so_settings.screen_height))

    pygame.display.set_caption('Space Vikers')

    last_tick = 0    

    ship = Ship(screen, so_settings)
    stats = Stats(so_settings, screen)


    bullets = Group()
    bullets_enemy = Group()
    enemies = Group()
    explosion = Group()

    exploAni = spriteSheet("animations/explosion.png", 5, 4)
    sb = ScoreBoard(so_settings, screen, stats, bullets, ship)
    btn = Button(screen)

    gf.start_background_music()

    clock = pygame.time.Clock()
    FPS = 120
    while True:
        clock.tick(FPS)

        while stats.main_menu:

            gf.move_bg(so_settings, screen, sb, stats, last_tick)
            btn.draw_button()
            pygame.display.flip()
            gf.check_event(screen, so_settings, ship, bullets, sb, stats, btn)

        if stats.game_active:
            gf.update_enemy_bullet(bullets_enemy, so_settings, screen)
            gf.update_bullet(bullets, so_settings, sb)
            gf.generate_enemy(so_settings, stats, last_tick, screen, ship, enemies, bullets_enemy, bullets, explosion, sb)
            gf.update(so_settings, screen, bullets, enemies, bullets_enemy, ship, exploAni, explosion, stats, sb)
            gf.move_bg(so_settings, screen, sb, stats, last_tick)
            gf.check_event(screen, so_settings, ship, bullets, sb, stats, btn)
        else:
            gf.move_bg(so_settings, screen, sb, stats, last_tick)
            gf.check_event(screen, so_settings, ship, bullets, sb, stats, btn)

run_game()

您的问题是慢速计算机无法处理 120 fps。您可以通过在 clock.tick 语句之后的循环中包含以下行来轻松检查：

print(clock.get_fps())

这将打印实际达到的 FPS

有办法解决这个问题。首先你可以根据clock.tick的返回值来使所有的移动速度：

dt = clock.tick()

然后在移动脚本的某个地方：

pos = pos+speed*dt # Just an example

这是你以后应该做的。

如果你不想重写你的运动系统，只需降低帧率：

FPS = 30
