if語句沒有意識到car1num和car2num的變化，只是忽略了它們打破了汽車的轉換和轉向。if語句沒有註冊變量

代碼略低於game_loop OK（）它說：「car2num = 2」和「car1num = 1」再後來它說

for event in pygame.event.get(): 
     if crashed == 0: 
      if event.type == pygame.KEYDOWN: 
       if event.key == pygame.K_RCTRL: 
        car2num += 1 
        if car2num == 4: 
         car2num = 1 
       if event.key == pygame.K_LCTRL: 
        car1num += 1 
        if car1num == 4: 
         car1num = 1

所以每按一次RCRTL car2num去並每次按下LCRTL car1num時間上升，甚至更晚（有一兩個car1num和car2num）

 if car2num == 1: 
      car2IMG = pygame.image.load('textures\car1.png') 
     if car2num == 2: 
      car2IMG = pygame.image.load('textures\car2.png') 
     if car2num == 3: 
      car2IMG = pygame.image.load('textures\car3.png')

那麼car1/2num的數量就決定了這輛車。

，但它會一直停留，因爲它最初被定爲「car2num = 2」和「car1num = 1」車。

非常感謝您提前幫忙，對於混亂而感到抱歉。

我有*絕對*不知道你想要什麼或你的問題是什麼。你的描述和代碼（轉儲）都不能解釋什麼是錯的 – UnholySheep

你確實需要提供一個[MCVE]並清楚地說明預期行爲與真實行爲之間的差異。否則，沒有人能夠幫助你。 – ImportanceOfBeingErnest

你有幾個downvotes，因爲你的問題目前很難理解。這不是個人的，它只是一個指標，這個特定的問題需要根據[問]指導方針進行編輯。您需要解釋代碼中的位置以及發生的情況。我們希望提供幫助，所以不要被貶低和評論所壓倒。衝電氣？ :) –

你具備的功能，如

def car1 (x1,y1): 
    gameDisplay.blit(car1IMG,(x1,y1))

將位塊傳輸的全球形象car1IMG。然後在您的game_loop函數中，您編寫了car1IMG = pygame.image.load('textures\car1.png')，它創建了一個本地變量具有相同的名稱。因此，除非您指定car1IMG是全局變量，否則game_loop函數中的所有內容都將使用局部變量而不是全局變量。因此：

def game_loop(): 
    gloabl car1IMG 
    ...
