hi everyone, i'm pretty new at processing and I'm tryin to write a little processing Pong game.

In order to understand when the ball hit the racket, I want the programm to test:
      1) if the ball is horizontally beyond the racket
            2) if 1 is true: test if the ball is vertically over the racket's lowest point
                  3) if 2 is true to test if the ball is under the racket highest point
                        4) if 3 is true, the ball is allowed to bounce
      -> otherway, you loose the game.

I wrote this in processing but I don't understand why I loose only and just if the ball is 2 is false (if the ball is under the racket limit) while I expected to loose olso if the ball goes beyond th racket limit over the racket itself.

Here is the code I wrote. (the prblem is at line 70).

1.      //ball position
   float xBar = 20;
   float yBar = mouseY;
   // ball speed
   float hSpeed = 10;
   float vSpeed = random(5);
   // bot position
   float yBot = 0;  
   
   void setup() {
     size(1000,500);
     noCursor();
   }
   
   void draw() {
     background(0);
     stroke(0,255,0);
     fill(0,255,0);
     strokeWeight(1);
     line(width/2, 0, width/2, height);
     strokeWeight(2);
   
     line(10,mouseY-20,10, mouseY+20);  //player
     line(width-10,yBot-20, width-10, yBot+20);  //bot
   
     rectMode(CENTER);    //ball
     rect(xBar, yBar, 5, 5);
   
     xBar = xBar + hSpeed;
     yBar = yBar + vSpeed;
   
     // bot mistake
     float ran = random(6);
     if(ran > 0.5) {
       yBot = yBar;
     }
     else {
       yBot = 0;
     }
   
     // bot bounce
   
     if (xBar > width-15) {
       if(yBar < yBot+20) {
         if(yBar > yBot-20) {
           xBar = width-15;
           hSpeed= -hSpeed;
         }
       }
       else {
         win();
       }
     }
     // vertical bounce
     if(yBar > height-5) {
       yBar = height-5;
       vSpeed = -vSpeed;
     }
   
     if(yBar < 5) {
       yBar = 5;
       vSpeed = -vSpeed;
     }
   
   
     //bounce angolation
     float diff = mouseY-yBar;
   
     // player bounce
     if(xBar < 15) {
       if(yBar < mouseY+20) {
         if(yBar > mouseY-20) {
           xBar = 15;
           hSpeed= -hSpeed;
           vSpeed= -0.2 * diff;
         }
         /*else {
           loose();
         }*/
       }
   
       else {
         loose();
       }
     }
   
   }
   
   //mouse click -> restart the game
   
   void loose() {
     noLoop();
     println("end program");
     text("YOU LOOSE",width/2-40,height/2);
     text("CLICK TO RESTART",width/2-60,height/2+15);
   }
   
   void win() {
     noLoop();
     println("end program");
     text("YOU WIN",width/2-30,height/2);
     text("CLICK TO RESTART",width/2-60,height/2+15);
   }
   
   void mousePressed() {
     println("program restart");
     xBar=10;
     yBar = mouseY;
     //hSpeed = 5;
     vSpeed = random(7);
     loop();
     draw();
   }

I fixed it by adding the same else function to the condition 2, but I still not understanding why I have to do it...
thanks!

Hello everyone, i'm trying to create an applet that randomly shows 5 images from an array of 15, but i'm stuck with the random array thing...
could anyone help me a little?

thanks
