Sorry forgot to add. The error points to the last ''}''

Re: expecting EOF, found 'class'

This is only part of the code correct?

You do have some weirdness in your mousePressed(). You have too many brackets, parenthesis, and an incorrectly placed semicolon. Cleaned up, it should look something like this:

//mouse press fires bullet
void mousePressed () {
if (bullet.bulletHit && !bullet.bulletFired) {
bullet.bulletFired = true;
bullet.bulletHit = flase;
}
}

Re: expecting EOF, found 'class'

You forgot the Alien class. There is no need to create the same class over and over. Just call it class AlienBullet {}
You don't put an "=" in the class either. You're also missing quite a few ";" in your Alienbullet code at the end of statements and you're setting int varibles to the class name. You're mixing cases and naming varibles the same as classes.. Sorry to say.. it's looking rough. You should start small and fix errors before moving forward.. you have a lot of code here and there are so many mistakes it's creating difficulties troubleshooting.

Minus the Alien class, it should look something like this:

Ship ship;
Bullet bullet;
Alien[] alien;
AlienBullet[] alienbullet;

int totalscore; //total score

Re: expecting EOF, found 'class'

thanks so much. Im slowly finding the small errors.

here is the alien class that I forgot

class Alien {//create class "Alien"

//Alien Variables

float AlienXPos;

float AlienYPos;

float AlienXSpeed;

float AlienYSpeed;

int AlienHP;

float AlienXcon;

float AlienXconBack;

int lastMillis = 0;

boolean AlienGameOver = false;

boolean AlienDead = false;

float AlienBulletX;

float AlienBulletY;

int AlienBulletLength = 10;

int AlienBulletSpeed = 50;

//Alien constructor

Alien(float _xpos, float _ypos )

{

AlienXPos = _xpos;

AlienYPos = _ypos;

AlienHP = 1;

AlienXcon = _xpos+100;

AlienXconBack = _xpos-100;

}

//Draw Alien

void display ()

{

if (AlienHP > 0) {

fill(0,0,255);

noStroke();

smooth();

ellipse(AlienXPos,AlienYPos,50,50);

}

boolean intersect (Bullet a) {

float distance = dist (AlienXPos,AlienYPos,bullet.bulletX,bullet.bulletY-Bullet.bulletLength/2);

if (distance < 10) {

return true;

} else {

return false;

}

//If Alien is hit

void HP () {

AlienHP = AlienHP-1;

ship.AlienCount = ship.AlienCount - 1;

bullet.bulletFired = false;

bullet.bulletHit = true;

} else {

AlienDead = true;

}

//How Aliens Move

void move () {

if (ship.Gameover = false) {

AlienXPos = AlienXPos + AlienXSpeed;
