Hello everyone once again! I’m having a problem trying to make a game, i have my concept and have gotten some help from my professor but im still coming up with errors.  
The concept of the game is you control a bubble that you need to keep away from a pin floating around. There is more I want to add but for now, I would like help figuring out why my timer won’t work.

```auto
class timer {
  // props
  int startTime;
  int interval;

  //constructor
  Timer(int timeInterval) {
    interval = timeInterval;
  }
  //methods
  void start() {
    startTime = millis();
  }
  
  void complete(){
    
    int elapsedTime = millis() - startTime;
    if (elapsedTime > interval) 
    {
      return true;
    } 
    else {
      return false;
    }//end if
  } 
}//end class

```

I’ve also attached screenshots to everyone who helps can have a visual understanding of what’s going on

The name of the class and constructor must be exactly the same including case so use either

```auto
class timer {
  // props
  int startTime;
  int interval;

  //constructor
  timer(int timeInterval) {
    interval = timeInterval;
  }

```

or

```auto
class Timer {
  // props
  int startTime;
  int interval;

  //constructor
  Timer(int timeInterval) {
    interval = timeInterval;
  }

```

Although both options are correct the second option is preferred because in Java class names are capitalized by convention.

Wonderful that worked for that problem! my next issue comes with the if statements it’s saying these variables don’t exsits im confused if I need to replace the words with myTimer or something else

```auto
Timer myTimer;

int currentTime;
String s;

void setup() {
  size(1200, 600);
  myTimer = new Timer(1000);
  s ="";
}

void draw() {
  background(200);

  //timer stuff
  if (myTimer.complete()== true){
    if (countdownTime > 0){
    currentTime++;
    countdownTIme--;
    timer.start();
  } 
  }
  
  else {
    fill (255, 0, 0);
    rect(0,0, width, height);
  }// end cdt

  // text stuff
  fill(255);
  textSize(48);
  textAlign(CENTER);
  s= "Current time is" + currentTime;
  s +="Countdown time is " + countdownTime;
  text(s,width/2, height/2);

}Timer myTimer;

int currentTime;
String s;

void setup() {
  size(1200, 600);
  myTimer = new Timer(1000);
  s ="";
}

void draw() {
  background(200);

  //timer stuff
  if (myTimer.complete()== true){
    if (countdownTime > 0){
    currentTime++;
    countdownTIme--;
    timer.start();
  } 
  }
  
  else {
    fill (255, 0, 0);
    rect(0,0, width, height);
  }// end cdt

  // text stuff
  fill(255);
  textSize(48);
  textAlign(CENTER);
  s= "Current time is" + currentTime;
  s +="Countdown time is " + countdownTime;
  text(s,width/2, height/2);

```

You need to correct the code above you seem to have the sketch coded duplicated. Also you need to include the code for your timer class.

Won’t work, you need myTimer.start() - the name of the object

Fixed that issue now saying it missing a “;” but i have one implemented there

```auto
class myTimer;

int currentTime;
String s;

void setup() {
  size(1200, 600);
  myTimer = new myTimer(1000);
  s ="";
}

void draw() {
  background(200);

  //timer stuff
  if (timer.complete()== true){
    if (countdownTime > 0){
    currentTime++;
    countdownTIme--;
    mytimer.start();
  } 
  }
  
  else {
    fill (255, 0, 0);
    rect(0,0, width, height);
  }// end cdt

  // text stuff
  fill(255);
  textSize(48);
  textAlign(CENTER);
  s= "Current time is" + currentTime;
  s +="Countdown time is " + countdownTime;
  text(s,width/2, height/2);

}

That won’t work. (the keyword `class` is only used where you define the class)

When your class is named `Timer` the line to use the class is:

`Timer myTimer = new Timer();`

It’s convention to have a class name (`Timer`) start with a Capital Letter. The object derived from the class is with a small letter: `myTimer`

To use a variable or function of the class, say `myTimer.start();` etc., using

- the object name and
- a dot . and
- the function name / variable name

you don’t use Timer there, you don’t the content of the class directly, only as myTimer.something…

Many errors just occurred saying the class “timer” doesnt exists and is suggesting a java import timer but that then makes even more issues

```auto
Timer myTimer = new Timer();

int currentTime;
String s;

void setup() {
  size(1200, 600);
  myTimer = new myTimer(1000);
  s ="";
}

void draw() {
  background(200);

  //timer stuff
  if (timer.complete()== true){
    if (countdownTime > 0){
    currentTime++;
    countdownTIme--;
    mytimer.start();
  } 
  }
  
  else {
    fill (255, 0, 0);
    rect(0,0, width, height);
  }// end cdt

  // text stuff
  fill(255);
  textSize(48);
  textAlign(CENTER);
  s= "Current time is" + currentTime;
  s +="Countdown time is " + countdownTime;
  text(s,width/2, height/2);

}

```

```auto

You need to copy paste the class at the end

i apologize for not responding for so long I was contemplating restarting from the ground up and decide to do that. I’m trying to figure out why “millis” won’t work

```auto
class myTimer {
  // props
  int startTime;
  int interval;
  
  //constructor
  myTimer(int timeInterval) {
    interval = timeInterval;
  }
  //methods
  void start() {
    startTime = millis();
  }
  
  boolean complete(){
    
    int elapsedTime = millis() - startTime;
    if (elapsedTime > interval) 
    {
      return true;
    } 
    else {
      return false;
    }//end if
  } 
}//end class

```

sorry was driving but here is the class code and the button code

This line implies that your class is named Timer,  
not myTimer
