asked on

creating a hold button for a java slot machine

Hi experts
i am currently designing a slot machine for a college project. i have manged to create the GUI and a few buttons.

i have a randomNumberGenerator class that creates 3 random numbers from 1 - 8. for example this how i generated one of my random numbers :-
public int oneRandomNum(){
    int randNum1;

  randNum1 = 1 + (int)(Math.random()*8);

return(randNum1);

}// this is done three times to generate 3 random numbers

Each number is assigned to an image using a switch statement in ( void btnStart_actionPerformed(ActionEvent e). So there are three switch statements one for each reel.

Each time the start button is clicked it loads the random images onto the 3 reels.  

Im having difficulty getting the hold buttons to work. Somehow i have to pause the randomNumberGenerator class for each reel individually.

any help would be appreciated

Add a couple of boolean variables tracking hold state. Add one for each wheel. Then add if statements for each wheel in your btnStart_actionPerformed(ActionEvent e) to determine if a certain wheel should be spun or not,
Of course, you would have to control the state of those booleans with the help of one hold button per wheel, and don't forget to reset the values of those variables after a run.

is there a specific command that i could use to hold a reel boolean or not?
at the moment my reels are just empty buttons that images are loaded on to when the start button is clicked.  hers the start button code
void btnStart_actionPerformed(ActionEvent e) {
    int resultOne, resultTwo, resultThree;
     
 if(e.getSource() == btnStart) {
 resultOne = rn.oneRandomNum()
 
   switch (resultOne)
    {
        case 1:
          jBReel1.setIcon(iconBanana) ;
                             break;

        case 2:
          jBReel1.setIcon(iconCherry) ;
                                 break;

        case 3:
          jBReel1.setIcon(iconApple) ;
                               break;

        case 4:
          jBReel1.setIcon(iconSun) ;
                       break;
        case 5:
          jBReel1.setIcon(iconCoke) ;
                       break;

        case 6:
          jBReel1.setIcon(iconStar) ;
                      break;

        case 7:
          jBReel1.setIcon(iconPie) ;
                        break;

        case 8:
          jBReel1.setIcon(iconCoolade) ;
                      break;
    }

    resultTwo = rn.oneRandomNumtwo();


  switch (resultTwo)
  {
      case 1:
        jBReel2.setIcon(iconBanana) ;
                  break;

      case 2:
        jBReel2.setIcon(iconCherry) ;
                    break;

       case 3:
         jBReel2.setIcon(iconApple) ;
                    break;

       case 4:
         jBReel2.setIcon(iconSun) ;
                  break;


       case 5:
         jBReel2.setIcon(iconCoke) ;
                   break;

                       break;

    case 8:
      jBReel2.setIcon(iconCoolade) ;
                     break;
  }


  resultThree = rn.oneRandomNumThree();


switch (resultThree)
{
    case 1:
      jBReel3.setIcon(iconBanana) ;
                    break;

    case 2:
      jBReel3.setIcon(iconCherry) ;
                     break;

     case 3:
