Hi,

Can you please format your code by using the `</>` button in the message editor or use backticks around your code like this : ``` code ``` → `code`.

You can edit your post to do that.

Pro tip : you can also press `Ctrl+T` in the Processing editor to auto format your code! 😉

Could you also give more details :

- Do you have a way to reset the game?
- Do you know how to detect if a key was pressed?
- How do you know if it’s a gameover?

Hi, I pressed the \</\> it did not do anything.

I dont have a way to reset game and i dont know how to do that.

I can do keypressed command, i know how to do that to detect keypressed.

The game is over when the star on top’s radius covers the screen. Thats when game over function screen shows up.

To reset your game, all you need to do is to put it back into the state that it was in when it started. That means you need to reset the values in all your variables to their initial state. The best way to do this is with a reset function. For example, if your game looks like this:

```auto
int score = 0;
int lives = 3;

void setup(){
  size(600,400);
  // Load things here, perhaps fonts or images.
}

void draw(){
  // Game code here.
}

```

Then you need to add the reset function and change it to this:

```auto
int score;
int lives;

void setup(){
  size(600,400);
  // Load things here, perhaps fonts or images.
  reset();
}

void reset(){
  score = 0;
  lives = 3;
}

void draw(){
  // Game code here.
  if( reset_time_is_now ){
    reset();
  }
}

```

Please realize that this is a demonstration of the CONCEPTS involved in doing a reset. You will need to apply this concept to your own code (because there is a lot of it and I’m not doing it for you).

how would i possibly reset something that has been shot via collision detection and was generated via a for loop. Because like resetting a for loop is what i want.

The for loop that generates it should be in the `reset()` function! That way, when the `reset()` functions runs, the for loop runs again, which puts the objects generated by the for loop back to their original state too.

```auto
int score;
int lives;
Enemy[] foes = new Enemy[20]

void setup(){
  size(600,400);
  // Load things here, perhaps fonts or images.
  reset();
}

void reset(){
  score = 0;
  lives = 3;
  for( int i = 0; i < foes.length; i++){
    foes[i] = new Enemy(i);
  }
}

void draw(){
  // Game code here.
  if( reset_time_is_now ){
    reset();
  }
}

```
