How to Use the Center Button for Menu Selection

[ogzhnkse]

Hi, I'm trying to write a short code snippet for a menu. I want to navigate through programs using the left and right buttons, then run the selected program by pressing the center button. After the program finishes, I’d like the menu to return to the last selected program. I checked the forum for solutions and tried the example below using hub.menu, but we're starting it with the Bluetooth button, which could cause an issue in FLL because Bluetooth has to be turned off.

        hub = base.hub  # InventorHub() nesnesi
        durum = 0
        
        # Robot ekranında başlangıçta 0 gözüksün
        hub.display.number(int(durum))
        
        # 30 saniyelik süre için
        first_job_started = False
        countdown_watch = StopWatch()  # Start/stop later
        
        
        
        while True:
            pressed = hub.buttons.pressed()
            hub.light.on(Color.GREEN)
            # Eğer ilk görev başladıysa 30 sn sayacını kontrol et
            if first_job_started:
                elapsed = countdown_watch.time() // 1000
                if elapsed >= 30:
                    hub.light.on(Color.RED)  # 30 sn sonu LED kırmızı
            
            if not pressed:
                wait(10)
                continue
            
            # SOL TUŞ => Durum bir arttır (9'dan sonra 1), ekranda göster
            if Button.LEFT in pressed:
                durum += 1
                if durum > 9:
                    durum = 1
                
                hub.display.number(int(durum))  # Ekrana sadece rakam
                
        
                # Tuş bırakılana kadar bekle (debounce)
                while Button.LEFT in hub.buttons.pressed():
                    wait(10)
        
            # SAĞ TUŞ => Mevcut durumu çalıştır (1..9)
            elif Button.BLUETOOTH in pressed:
                
                
                # İlk defa görev başlıyorsa sayaç reset (30 sn takibi)
                if not first_job_started and (1 <= durum <= 9):
                    first_job_started = True
                    countdown_watch.reset()  # Sayaç sıfır
                
                if   durum == 1: sonar()
                elif durum == 2: yya()
                elif durum == 3: ornektoplama()
                elif durum == 4: coralnursery()
                elif durum == 5: batikgemi()
                elif durum == 6: trident()
                elif durum == 7: gemibirak()
                elif durum == 8: balinabesle()
                elif durum == 9: fener()
                else:
                    print("Henüz geçerli bir görev seçilmedi (0)")
        
                while Button.RIGHT in hub.buttons.pressed():
                    wait(10)
        
            wait(10)

Maybe some interesting ideas here: https://github.com/orgs/pybricks/discussions/1401

However, It cannot force the program to stop while the menu is selected and the function is running.
Sometimes they have to force their robot to stop its unwanted movements.

Is there any way?

Thank you @dlech

Actually, I had seen this discussion before, but another suggestion within it solved my problem. We use the center button to start and the Bluetooth button to stop, which turned out to be quite effective.
