[Java]Pytanie problem z gra...

[teresiako]

Witam. Otoz mam pewien problem, robie projek na zajecia z programowania. Jutro mam termin oddania ;D. Mam dozrobienia gre, byc moze kazdy ja zna, nazywa sie 15+1. Jakby co, polega ona na tym ze mamy 15 losowo uporzadkowanych liczb na siatce 4x4, w tym jedno puste pole. Nalezy uporzadkowac je w kolejnosci od 1 do 15, z tym ze mozemy przesuwac buttony od liczby do buttona pustego. No i mam juz prawie caly kod, tzn mam losowe uporzadkowanie liczb i czesc akcji wiem co dalej robic ale stoje w mijescu. Calosc zrobilem na JFrame i powrzucalem 16 buttonow, zmienna tablicowa przypisalem do kazdego nr od od do 15(0 narazie robi za pusta kratke).
No i programuje eventy, czyli mouseClicked. Zaprogramowalem narazie 4 buttony, na zasadzie pelti ktora sprawdza nr na otaczajacych dana kratke buttonach. jesli bedzie 0, zmienia text, oprocz tego zaprogramowalem button (START)ktory losowo uklada liczby. No i jak ulozymy je w kolejnosci losowej i nacisne na ktorys z guzikow program dziala zmienai tex itd, ale dziala top tylko raz i tylko z jednym guzikiem, jak np na guziku 2 jest 0 i wcisne guzik 1 to zamienia sie textami, ale jesli chce teraz zrobic odwrotnie to juz nic nie dziala, poza tym ktory losuje od nowa liczby. Pytanie co tu jest nie tak, teoretycznie powinno dzialac....



Daje listing tego co mam(czesc kodu usunalem bo sie nie miescil, chodzi glownie o eventy tych 4 buttonow, jakby co naywaja sie b1 do b5 ;P:

Kod: Zaznacz cały

Wydaje mi się po kliknięciu zmieniasz jedynie napisy na przyciskach,
natomiast nie zmieniasz stanu zmiennych m.

Kod: Zaznacz cały

private void b4MouseClicked(java.awt.event.MouseEvent evt) {
        // TODO add your handling code here:
        if(m3==0){
            b4.setText(String.valueOf(m3));
                    b3.setText(String.valueOf(m4));        }

       if(m8==0){b4.setText(String.valueOf(m8));
        b8.setText(String.valueOf(m4));}
    }

Spróbuj może dodać zmianę stanu np.

Kod: Zaznacz cały

private void b4MouseClicked(java.awt.event.MouseEvent evt) {
  if(m3 == 0){
    b4.setText(String.valueOf(m3));
    b3.setText(String.valueOf(m4));
    m3 = m4;
    m4 = 0;
  }
else
   if(m8 == 0) {
    b4.setText(String.valueOf(m8));
    b8.setText(String.valueOf(m4));
    m8 = m4;
    m4 = 0;
  }
}
