How to alternate between three states

Epicness35

Hi, I am making a game in Processing. One part is the home screen, a second part is the actual game, and the third part is going to be a game over screen. I can make it so the home screen goes to the actual game by using a boolean, but how would I display the game over screen, with everything else not shown?

Stop using a boolean. Instead, number your states 0 (for the home page), 1 (the game), and 2 (game over screen). Then use an integer to remember which state you're in instead of a boolean. Change you if statements to check the value of that integer instead of just checking if your boolean is true or false.

int state;

if( state == 0){

} else if(state ==1){

} else if(state == 2) {

}

I find using numbers a bit cryptic so usually define constants at the top of the code for each state and then use those names throughout:

static final int HOME_PAGE = 0;
...

if( state == HOME_PAGE){
...

void draw() {

    // outside switch nothing is allowed in draw() !!!

    switch(state) {

        case HOME_PAGE:
        //
        displayHomepage();
        break;

        case GAME_PAGE:
        //
        displayGame();
        break;

        case GAME_OVER_PAGE:
        //
        displayGameOver();
        break;

    }//switch

}//draw()

// -------------------

void displayHomepage() {

}


void displayGame() {

}



void displayGameOver() {

}
