我正在嘗試創建一個太空入侵者游戲。其中我必須顯示不同的波浪 1,2,3 我已經撰寫了代碼
wave1="bgk.png"
if wave1!=wave:
screen.blit(pygame.image.load(wave),(615,480))
wave="bgk.png"
time.sleep(3)
screen.blit(pygame.image.load(wave),(615,480))
在達到一定數量的分數后，這里的“波浪”會發生變化，但是
問題是第一個影像在 3 秒休息之前沒有加載。3 秒后，它加載了大約 0.1（可以忽略）的時間，你可以看到你是否仔細觀察我不知道是什么導致了這個問題，請幫忙
完整代碼在這里

我對編碼文化很陌生我不知道如何使用 StackOverflow 我可能犯了一些愚蠢的錯誤，對此我感到非常抱歉
uj5u.com熱心網友回復：
pygame.image.load()是一個非常耗時的操作。它必須從卷中讀取檔案并解釋影像資料。在應用程式回圈之前加載所有影像并在回圈中使用它們
不要在應用程式回圈中“延遲”、“等待”或“睡眠”（請參閱如何在 pygame 中等待一段時間？）。pygame.time.get_ticks()用于測量時間。pygame.time.get_ticks()回傳自pygame.init()呼叫以來的毫秒數。
添加一個current_bg宣告當前背景影像的變數。在某個時間點之后更改變數：
bg_image = pygame.image.load("bg.png")
bgk_image = pygame.image.load("bgk.png")
current_bg = bg_image
running=True
while running:
current_time = pygame.time.get_ticks()
if current_timev > 3000: # 3000 milliseconds == 3 seconds
current_bg = bgk_image
screen.blit(current_bg, (0,0))
