This example by definition can only have the cars move horizontally because only the x value is adjusted. You’ll need to have both an xspeed and a yspeed. You could take a look at polar to cartesian coordinates (which is a nice way of moving objects in a circle) or vector-based motion.

Hey!
I am trying to get these two to drive in a sort of circle around an oval. My window is set up so its like a race track, and there are five cars which are supposed to revolve around the track, (it is alright if they take sharp turns in a square). Any tips?

You can draw a line like so:

line(myCar1.x,myCar1.y,myCar2.x,myCar2.y)

And it might be worth building this functionality into the car class, i.e.

myCar1.drawConnection(myCar2);

How can I create lines between the cars (if I create 3 cars)? (line between car 1 and car2, line between car 2 and car 3, line between car 1 and car 3)??
thank you
