I have a slight difficulty. When i get the app version of my game or when i import it it's impossible for me to read/see the quoted messages that can't be read trough Greenfoot.
import javax.swing.
JTextArea; JOptionPane.showMessageDialog(null, text, "Copy and paste", JOptionPane.INFORMATION_MESSAGE);
I think only those lines are really necessary because i just tried them and it worked but i guess it depends on how your code was designed .
