We went through varibles and functions, and created a program pongball that is the first start towards a bouncing Pong ball
int ballx = 0; int bally = 200; int pballx = 0; int pbally = 200; void setup() { // size of our drawing window size(400, 400); // set the background color to gray background(128); } void draw() { // draw over the previous ball location stroke(128); // gray fill(128); drawball(pballx,pbally); // update the ball location ballx = ballx + 2; bally = bally + 1; // and draw it stroke(255); fill(255); //white drawball(ballx,bally); // save the new location for next time pballx = ballx; pbally = bally; } // draw a paddle-shaped box at the given coordinates void drawbox(int x, int y) { rect(30,y,10,40); } // draw a ball at the given coordinates void drawball(int foo, int bar) { ellipse(foo,bar,10,10); }
