A Message object has a name and contains several Command objects. Consider the kinds of hazards we might encounter on Mars, how they would behave, and how we might be alerted to their presence as you complete this next step and further define the behavior of hazards in your game. Different command On Mars, rovers have to navigate hazards such as rocky or sandy terrain, dust storms, and other inclement weather. To learn more, see our tips on writing great answers. However, the harsh terrain on Mars with hazards like boulders, sand, and craters means that moving rovers from one place to another is no simple task. You are given the initial starting point (x,y) of a rover and the direction (N,S,E,W) it is facing.
