     public int Kontostand;
     public Text KontostandText;
 
     public Inventory myInventory;
   
    
    
     
     // Start is called before the first frame update
     void Start()
     {
 
        
         KontostandAktualisieren();
 
         
 
     }
 
 
     public void buyJoli(int shopPrice)
     {
         if (Kontostand >= shopPrice)
         {
             Debug.Log("Character wurde gekauft");
 
             // Dodgie hinzufügen
             myInventory.buyNewJoli();
             // Kontostand neu berechnen
             Kontostand = Kontostand - shopPrice;
             Debug.Log("Kontostand:" + Kontostand);
 
             //Kontostand aktualisieren
             KontostandAktualisieren();
 
             // Button deaktivieren
 
          
                 GameObject.Find("Joli").GetComponent<Button>().interactable = false;
             
 
         }
        
 
         }
