    The way I understand it, once you run your program, the timer automatically starts, however in this code, there should be some kind of

    `if(score>=100){
//timer
//banner
}`

    though that doesn't work. Can someone help me figure it out?

    you just need to stet startTime in the moment the Boss mode starts (that's where it says state = stateBoss; ):

       startTime=millis(); // !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

    I also corrected the if / else clause with the timer and made a new boolean bossGameStarted so that mouse clicks are ignored during the banner time. (This variable could be replaced with a new state bannerBeforeBoss or so.)

    here is the full sketch

    final int stateSampleGame = 0;
final int stateBoss = 1;
final int stateVictory = 2;

int state = stateSampleGame;

boolean bossGameStarted=false; 

void setup () {
  size (960, 640);
  background(255);
}
void draw () {
  background(255);
  switch (state) {
  case stateSampleGame:        
    gameScreen();
    break;
  case stateBoss:        
    bossScreen();
    break;
  case stateVictory:  
    victoryScreen();
    break;
  default:    // error
    println("Error number 939; unknown state : "
      + state 
      + ".");
    exit();
    break;
  } // switch
}

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

void keyPressed () {
  switch (state) {
  case stateSampleGame:        
    keyPressedForGameScreen();
    break;
  case stateBoss:        
    keyPressedForBossScreen();
    break;
  case stateVictory:  
    keyPressedForVictoryScreen();
    break;
  default:    // error
    println("Error number 939; unknown state : "
      + state 
      + ".");
    exit();
    break;
  } // switch
}

void mousePressed () {
  switch (state) {
  case stateSampleGame:        
    mousePressedForGameScreen();
    break;
  case stateBoss:        
    mousePressedForBossScreen();
    break;
  case stateVictory:  
    mousePressedForVictoryScreen();
    break;

  default:    // error
    println("Error number 939; unknown state : "

    @Chrisir Hi Chrisir, thanks for giving an answer to the code but it caused another problem, I actually have a

            If (key=='p'){
        state=statePause
        }

    in both the KeyPressedForGme and KeyPressedForBoss screen. I thought the timer problem would not affect it. The problem right now is when you pause in the boss screen, the game will be paused. However after resuming the game, the banner "animation" will play first. Thanks again.

    Line 114 use bossGameStarted

    here in an appropriate way for example

    like here:

    lots of other changes like variable previousState

    final int stateSampleGame = 0;
final int stateBoss       = 1;
final int stateVictory    = 2;
final int statePause      = 3; 
int state = stateSampleGame;
int previousState = stateSampleGame;

// false: Banner is allowed to appear: 
boolean bossGameStarted=false; 

void setup () {
  size (960, 640);
  background(255);
}

void draw () {

  background(255);

  switch (state) {

  case stateSampleGame:        
    gameScreen();
    break;

  case stateBoss:        
    bossScreen();
    break;

  case stateVictory:  
    victoryScreen();
    break;

  case statePause:
    pauseScreen();
    break; 

  default:    // error
    println("Error number 939a (in function draw()); unknown state : "
      + state
