I've been trying to get this floating ball to bounce off of colored ellipse objects (or Bumpers) tangent to where it hits the Bumper. Right now I use a range of x and y values to determine where each Bumper is -kinda- and the ball bounces backward where it came from.

The Bumpers are static objects stored in a class.

Here's some code...



class Ball {
 float xpos;        
 float ypos;        
 float xspeed;      
 float yspeed;    
 int size = 30;
 
 Ball() {
   xpos = 480;
   ypos = 0;
   xspeed = 2;
   yspeed = 4;
 }

 void display () {
 stroke(0);
 fill(255,228,10);
 ellipse(xpos+size/2, ypos+size/2, size, size);
 }
 
 void move() {
 float xdirection = 1;
 float ydirection = 1;

 xpos = xpos + ( xspeed * xdirection );
 ypos = ypos + ( yspeed * ydirection );
 

 if (xpos > 850-size || xpos < 100) {       //walls
   xspeed *= -1;
 }
 if (ypos > 800-size || ypos < 0) {
   yspeed *= -1;
 }

 
 //Bumper Collision
 //Luigi
   if(xpos > 210 && xpos < 260 && ypos > 345 && ypos < 415) {
     yspeed *= -1;
     xspeed *= -1;
     score =  score + 100;
   }
   
   //Mario
   if(xpos > 422 && xpos < 472 && ypos > 190 && ypos < 250) {
     xspeed *= -1;
     yspeed *= -1;
     score = score + 225;
   }
   
   //Toad
   if(xpos > 650 && xpos < 725 && ypos > 500 && ypos < 570) {
     xspeed *= -1;
     yspeed *= -1;
     score = score + 75;
   }
   
   
   //Peach
   if(xpos > 210 && xpos < 280 && ypos > 500 && ypos < 570) {
     xspeed *= -1;
     yspeed *= -1;
     score = score + 75;
   }
   
   //Yoshi
   if(xpos > 510 && xpos < 580 && ypos > 500 && ypos < 570) {
     xspeed *= -1;
     yspeed *= -1;
     score = score + 100;
   }
 
 }
 }
