Hey everyone,

I am very new to processing and I have been watching Jose Sanchez's tutorials to help get me up to par.

I was following his tutorial on vector classes and I keep getting the error, 'cannot find anything named "loc"'

Help?

first tab:

second tab: (where the problem occurs)

class Ball {
//global variables
Vec3D loc = new Vec3D (0, 0, 0);
Vec3D speed = new Vec3D (random(-2, 2), random(-2, 2), 0);
//constructor
Ball(Vec3D _loc) {
loc = _loc;
}
//functions
void run() {
//display
display();
//move
move();
//bounce
bounce();
}
}
void bounce () {
if (loc.y > height) { <--- this is what it highlights to give me an error message.
speed.y= speed.y *-1;
}
if (loc.y < 0) {
speed.y=speed.y *-1;
}
if (loc.x> width) {
speed.x=speed.x*-1;
}
if (loc.x<0) {
speed.x=speed.x*-1;
}
}
void move() {
loc.addSelf(speed);
}
void display() {
ellipse(loc.x, loc.y, 20, 20);
}
