為什麼 pygame.event.get() 在執行緒執行時不傳回事件？

pygame.event.get() Not Returning Events Inside Thread

Issue:

🎜>在 a pac-man style game using PyGame, the receiving_inputs function is not retrieving any keyboard events when executed within a thread, while mouse events are still registered.

def receiving_inputs(self):
    while True:
        events = pg.event.get()
        for event in events:
            if event.type == pg.KEYDOWN:
                # Handle keyboard input
        time.sleep(1/60)

threading.Thread(target=self.receiving_inputs).start()

Resolution:

PyGame event handling must occur in the main thread.

According to the PyGame event documentation event subsystem should be called from the main thread.

雖然可以從其他執行緒發送事件，但事件佇列必須在主執行緒中處理。因此，解決方案是將 event.get() 通話移至主執行緒。
