将游戏分割成不同的文件后，Pygame 运行速度变慢

Question

我用 pygame 编写了一个简单的游戏。它曾经全部在一个文件中，但我决定保持它的干净，所以我将代码分成不同的脚本。这样做之后，游戏的运行速度比以前慢了很多。我相信延迟是由每帧引用导入的变量和函数引起的，但仍然不知道如何解决问题。这是代码，希望对您有所帮助：

ma​​in.py

import pygame
import player
import window

def main():
    pygame.init()

    running = True

    clock = pygame.time.Clock()

    while running:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                running = False

        window.refresh()
        player.run()

        clock.tick(window.FPS)
        print(clock.get_fps())
        pygame.display.update()

    pygame.quit()

if __name__ == "__main__":
    main()

player.py

import pygame
from math import sqrt
from window import WIDTH, HEIGHT, WIN
from classes import *

player = Obj(50, 50, 50, 10)

def normalize(x, y):
    if x != 0 and y != 0:
        return (x / sqrt(2), y / sqrt(2))
    return (x, y)


def movement(obj: Obj):
    keys = pygame.key.get_pressed()

    startx = obj.x
    starty = obj.y

    x = 0
    y = 0

    if keys[pygame.K_w]:
        y -= obj.vel
    if keys[pygame.K_d]:
        x += obj.vel
    if keys[pygame.K_a]:
        x -= obj.vel
    if keys[pygame.K_s]:
        y += obj.vel

    pos = normalize(x, y)

    obj.x += pos[0]
    obj.y += pos[1]

    speed = abs(sqrt((obj.x - startx) ** 2 + (obj.y - starty) ** 2))
    # print(speed)


def on_track(obj: Obj):
    if obj.x >= WIDTH - obj.size:
        obj.x = WIDTH - obj.size
    if obj.x <= 0:
        obj.x = 0
    if obj.y >= HEIGHT - obj.size:
        obj.y = HEIGHT - obj.size
    if obj.y <= 0:
        obj.y = 0


def run():
    pygame.draw.rect(WIN, (Color.black), (player.x, player.y, player.size, player.size))
    movement(player)
    on_track(player)
    pygame.display.update()

window.py

from classes import *
import pygame

WIDTH, HEIGHT = 800, 600
WIN = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption("Game")
FPS = 60


def refresh():
    WIN.fill(Color.white)

classes.py

class Color(): 
    white = (255, 255, 255)
    black = (0, 0, 0)
    blue = (0, 0, 255)
    red = (255, 0, 0)
    green = (0, 255, 0)


class Obj():
    def __init__(self, x, y, size, vel):
        self.x = x
        self.y = y
        self.size = size
        self.vel = vel

谢谢你提前！

您调用pygame.display.update两次（在player.run和main.main中）。
从 player.run 中删除它可以解决问题。
