This will be very similar to the moveForward() function. use by writing tests and classes for the Mars rover named Curiosity. In this activity you'll use code to design a game inspired by the way NASA rovers navigate on Mars. Each class has accompanying unit tests in their respective "spec.js" file located in the "spec" folder. In our first pass, hazards had a fairly simple set of parameters. The dust plume disappears past the top of the frame, so an exact height can't be known, but it's estimated to be at least 164 feet (50 meters) tall. Now it comes iteration #2 where I need. Changes to these files could effect your grade. sign in That is to say, we want the game loop to run after every single movement, not just move once and hang. So,.
