I have an assignment to do where there is a stationary target in the middle and enemies move towards the target and the user will need to click over the enemies to destroy them. I have encountered a problem in my Target class when there is a syntax error “syntax incomplete statement or extra code near ‘extraneous input’”. The error is on line 15.

```auto
class Target {
  float x, y; // coordinates of the target
  int radius = 25; // radius of the target
  PImage img; // image for the target

  Target(float x, float y) {
    this.x = x;
    this.y = y;
    img = loadImage("target.png");
  }

  void draw() {
    image(img, x - radius, y - radius);
  }
}

```

we need to see more, since this part is correct

```auto

void setup() {
  size(333, 333);
}

class Target {
  float x, y; // coordinates of the target
  int radius = 25; // radius of the target
  PImage img; // image for the target

  Target(float x, float y) {
    this.x = x;
    this.y = y;
    img = loadImage("target.png");
  }

  void draw() {
    image(img, 
      x - radius, y - radius);
  }
}//class
//

this sees to run

remove my class Target

you had the global variables speed etc. repeated which is not necessary and not allowed

```auto

//float speed; // speed at which the enemies move
//boolean gameOver; // true if the game is over, false otherwise
//int score; // current score
//PImage backgroundImg; // image for the background

class Enemy {
  float x, y; // coordinates of the enemy
  int radius = 25; // radius of the enemy
  boolean alive; // true if the enemy is alive, false if it has been destroyed
  PImage img; // image for the enemy

  Enemy(float x, float y) {
    this.x = x;
    this.y = y;
    alive = true;
    img = loadImage("enemy.png");
  }

  void update(float targetX, float targetY) {
    // move the enemy towards the target
    float dx = targetX - x;
    float dy = targetY - y;
    float angle = atan2(dy, dx);
    x += cos(angle) * speed;
    y += sin(angle) * speed;

    // check for collision between the enemy and the target
    float distance = dist(targetX, targetY, x, y);
    if (distance < radius) {
      gameOver = true; // end the game
    }
  }

  void draw() {
    if (img!=null)
      image(img, x - radius, y - radius);
  }
}

// main sketch:

float speed; // speed at which the enemies move
boolean gameOver; // true if the game is over, false otherwise
int score; // current score
PImage backgroundImg; // image for the background

Enemy enemy; // enemy object
Target target; // target object

void setup() {
  size(400, 400);
  target = new Target();
  enemy = new Enemy(50, 50);
  speed = 2;
  gameOver = false;
  score = 0;
  backgroundImg = loadImage("space.jpg");
}

void draw() {
  if (backgroundImg!=null)
    image(backgroundImg, 0, 0);

  if (!gameOver) {
    if (enemy.alive) {
      enemy.update(target.x, target.y); // move the enemy towards the target
      enemy.draw(); // draw the enemy
    } else {
      // enemy has been destroyed, spawn a new one
      enemy = new Enemy(random(0, width), random(0, height));
      score++;
    }
  }//if
}//func

you forgot to post the Target class though

sorry, here’s the target class

```auto
class Target {
  float x, y; // coordinates of the target
  int radius = 25; // radius of the target
  PImage img; // image for the target

  Target(float x, float y) {
    this.x = x;
    this.y = y;
    img = loadImage("target.png");
  }

  void draw() {
    image(img, x - radius, y - radius);
  }
}

```
