The solution is to add a static class containing the global variables. Using a global variable violates the OOP concept a bit, but can be very useful in certain circumstances. Be aware, that using global variables is not the answer to all questions and should only be used if using instances/parameters is not practical! You should also be careful when using multithreading, e.g. a background...
