Hi guys, thanks again for your help over the last week or so, I'd have been lost without it.  The game I've been working on is now finished and I thought I'd stick it on here (I'll put it in the "Share your Work" section too").

However I do have one final, small, query.  If the player loses the final boss battle, a laughter sound plays.  For some reason a small part of it loops endlessly and I can't see why.  Any suggestions would be greatly appreciated and I promise this will be the last thing I ask of you. 

Thanks again.

Again, this seems to be a fairly common problem, but none of the previous threads really helped me.

I'm struggling to get "bullets" (generated by an array, adding a new one on keypress) to collide with "asteroids" just generated by an array.

What's the best way to share the .zip with you guys?
Dropbox link ?

I've been searching the forums and everyone complains about how many countdown/timer questions are asked, yet I haven't found a thread which has been of any use.

I'm trying to implement a countdown which will begin, not at the start of the program, but later on (once int currentLevel = 3 to be precise).  The countdown has to begin at 60 seconds and return a boolean once it finishes.

As I say, Im having no luck coding this on my own or through searching the forums so any advice, explanations, or examples would be greatly appreciated :)

Sorry to ask so many questions in such a short space of time, but I'm really struggling with this.  I require the "pirates" in my code to intersect the "fuel cells" and when they do the cells must disappear.  No matter how I try it, the pirates just go straight through the fuel as if no collision is recorded. Both the pirates and fuel cells are generated by arrays.

Here's the Pirate class

1. //Create pirate class
   class Pirate {
     float xPos;
     float yPos;
     float xSpeed;
     float ySpeed;
   
     //Pirate radius
     int pr = 20;
   
     Pirate(float tempXPos, float tempYPos, float tempXSpeed, float tempYSpeed) {
       xPos = tempXPos;
       yPos = tempYPos;
       xSpeed = tempXSpeed;
       ySpeed = tempYSpeed;
     }
     //Hit function for pirates when they collide with the player
     void hit() {
       xPos = random(width);
       yPos = random(60, height);
     }
   
     //Display function for pirates  
     void display() {
       image(imgCar, xPos, yPos);
       pr = 20;
       xPos = xPos + xSpeed;
       yPos = yPos + ySpeed;
       if (xPos > width) {  //Pirates reset if they go off screen
         xPos = 0;
       }
       if (xPos < 0) {
         xPos = width;
       }
       if (yPos > height) {
         yPos = 45;
       }
       if (yPos < 45) {
         yPos = height;
       }
     }
   
     //Specify intersect conditions for player and pirates 
     boolean intersect(Player a) {
       float distance = dist(xPos, yPos, a.x_, a.y_);
       if (distance <= pr + a.r) {
         return true;
       }
       else {
         return false;
       }
     }
   
     //Specify intersect conditions for pirates and fuel
     boolean intersect(Fuel f) {
       float distance = dist(xPos, yPos, f.xF, f.yF);
       if (distance <= pr + f.fr) {
         return true;
       }
       else {
         return false;
       }
     }
   }
   

And the Fuel class

1. //Create fuel class
   class Fuel {
     float xF;
     float yF;
     //Fuel radius
     int fr = 20;
   
     Fuel(float posX, float posY) {
       xF = posX;
       yF = posY;
     }
   
     //Create show function for fuel
     void showFuel() {
       image(imgFuel, xF, yF);
     }
   
     //Specify intersect conditions for fuel and player
     boolean intersect(Player a) {
       float distance = dist(xF, yF, a.x_, a.y_);
       if (distance < fr + a.r) {
         return true;
       }
       else {
         return false;
       }
     }
   
     //Create collect function for when player picks up fuel
     void collect() {
       xF = (random(width));
       yF = (random(60, height));
       fuel = fuel + 100;
     }
   
     //Create lose function for when pirates collide with fuel
     void lose() {
       xF = 1000;
       yF = 1000;
     }
   }
   

And the code I'm trying to use to control behaviour upon collision

1.        //Pirate starting positions
     for (int i=0; i<pirates.length; i++) {
       int pSpeedx = (int)random(8);
       int pSpeedy = (int)random(8);
       pirates[i] = new Pirate(random(width), random(60, height), pirateSpeeds[pSpeedx], pirateSpeeds[pSpeedy]);
     }
   
2.    //Fuel Cell starting positions
     for (int i=0; i<cells.length; i++) {
       cells[i] = new Fuel(random(width), random(60, height));
     }
3.     //Show pirates
       for (int i = 0; i < pirates.length; i++) {
         pirates[i].display();
       }
4.     //Show fuel cells
       for (int i=0; i<cells.length; i++) {
         cells[i].showFuel();
       }
   
5. if (pirates[i].intersect(cells[i])) {
           cells[i].lose();
         }
   

Ok, I've modified the code I submitted earlier to use arrays a bit, however I'm struggling with specifying the variables of objects within an array. 

For example: I want the cars in this code to appear at y=135, y=235, y=335, and y=445. Furthermore, I want all those which appear at y=135 to have speed=-12; those at y=235 to have speed = 8; those at y=335 to have speed -5; and those at y=445 to have speed 4.

Furthermore, I can't find a resource which tells me how to implement intersecting the "cars" with the player when they are generated by an array like this.

What am I missing?

1. Car[] cars = new Car[15];
   
   PImage img;
   PImage imgCar;
   PImage imgSplash1;

   //Declare variables for initial game conditions
   int fuel = 0;
   int lives = 5;
   int score = 0;
   int currentLevel = 0;
   boolean gameOver = false;
   
   void setup() {
     size(800, 600);

     lives = 5;
     f = createFont("Arial", 12, true);
   
     //Load the background image
     img = loadImage("road.jpg");
     imgCar = loadImage("car.jpg");
     imgSplash1 = loadImage("splash1.jpg");
     imgSplash2 = loadImage("splash2.jpg");
     imgSplash3 = loadImage("splash3.jpg");
   
     //Car starting positions, direction, and speed
     for (int i=0; i<cars.length; i++) {
       cars[i] = new Car(random(width), 135, -12);
     }
     //Player starting poition
     alien = new Player(400, 550);
   
     //Collectable ship parts position
     part1 = new Part(175, 150);
     part2 = new Part(620, 250);
