Question

嗨，我是Pygame的新手，我想在左上方显示一个带有FPS计数器的紫色屏幕的窗口;然而，它不断显示黑屏，其中没有任何内容。当我运行我的代码时，它根本不显示任何错误。

import pygame
import time
from scripts.UltraColor import*

pygame.init()

currentSec = 0
currentFrame = 0
FramePerSec = 0

fps_font = pygame.font.Font("C:\\Windows\\Fonts\\Verdana.ttf", 20)



def count_FramePerSecond():
    global currentSec, currentFrame, FramePerSec
    # during the current second, this will record how many frames there are
    if currentSec = time.strf("%S"):
        currentFrame += 1

    else:
        FramePerSec = currentFrame
        #records the frame that were added during the second

        currentFrame = 0
        #resets the counter back to zero so it can record during the next second
        currentSec = time.strf("%S"):
        #sets the current second variable to the current second

def show_FramesPerSecond():
    fps_overlay = fps_font.render(str(FramesPerSecond), True, Color.Goldenrod)
    window.blit(fps_overlay, (0,0))

def create_window():
    global window, window_title window_height, window_width, 

    window_title = "Crappy RPG Game"

    window_height = 700
    window_width = 900

    pygame.display.set_caption(window_title)

    window = pygame.display.set_mode((window_height, window_width), pygame.HWSURFACE|pygame.DOUBLEBUF)




create_window():

is_gameRunning = True

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


    #Logic
    count_FramePerSecond()

    #Render Graphics:
    window.fill(255,0,255)
    show_FramesPerSecond()

    pygame.display.update()




pygame.quit()
quit()

我再次对堆栈溢出和pygame都很新，很抱歉，如果这是一个明显的错误

有多种语法错误。如果您看不到错误消息，请安装一个可以显示给您的IDE（我不熟悉Windows抱歉）。

if currentSec = time.strf("%S"):

应该是：

if currentSec == time.strf("%S"):

此外：

    currentSec = time.strf("%S"):

=＆GT;

    currentSec = time.strf("%S")

此处global window, window_title window_height, window_width,和:中的逗号中缺少逗号：create_window():

如果您是初学者，则应首先运行示例，然后对其进行调整以了解其工作原理。如果没有测试就不要尝试写几十行......

Pygame窗口没有显示任何内容
