Modifying Multiple "Physical" Parameters IF YOU ARE WILLING TO CHANGE THE VALUES OF SEVERAL VARIABLES EACH TIME YOU "animate" YOU CAN SIMULATE ACCELERATION, TWO DIMENSIONAL MOTION, ETC. public void animate() { pen.clearRect(); if (y > 250) { yspeed = - yspeed; } yspeed = yspeed + gravity; y = y + yspeed; pen.fillOval(x,y,8,8,''red''); } YOUR BROWSER DOES NOT SEEM TO KNOW ABOUT APPLETS Applet Source code
