Help with concentration program
For some reason my program will not draw the buttons, also I have a comment put in for a line of code that I do not know how to implement.
Any help is appreciated
Main.java import javax.swing.JOptionPane; public class Main { public static void main( String[] args ) { int clicks = 0; int matched = 0; boolean live = true; int choice1 = 0, choice2 = 0; GUI mainGameWindow = new GUI(); GLogic gameLogic = new GLogic(mainGameWindow.getAmountOfButtons()); mainGameWindow.setVisible( true ); while( live ) { ++clicks; //wait for action in mainGameWindow if(clicks % 2 == 1) { choice1 = mainGameWindow.getButtonClicked(); mainGameWindow.setButtonText(choice1, Character.toString(gameLogic.getCharacter(choice1))); mainGameWindow.disableButton(choice1); } else { choice1 = mainGameWindow.getButtonClicked(); mainGameWindow.setButtonText(choice2, Character.toString(gameLogic.getCharacter(choice2))); mainGameWindow.disableButton(choice2); if( gameLogic.checkMatch( choice1, choice2 ) ) { mainGameWindow.setButtonColorBLUE(choice1); mainGameWindow.setButtonColorBLUE(choice2); ++matched; ++matched; if(matched == mainGameWindow.getAmountOfButtons()) { mainGameWindow.setCompletedMessage("Game completed." ); JOptionPane.showMessageDialog( null , "Completed! in " + ( clicks / 2 ) + " attempted matches!" , "COMPLETED" , JOptionPane.INFORMATION_MESSAGE ); } } else { try { Thread.sleep( 500 ); } catch ( InterruptedException z ){ z.printStackTrace(); } mainGameWindow.setButtonText(choice1, ""); mainGameWindow.setButtonText(choice2, ""); mainGameWindow.enableButton(choice1); mainGameWindow.enableButton(choice2); } } } } }
