A rover's position and location is represented by a combination of x and y co-ordinates and a letter representing one of the four cardinal compass points. Please Each rover will be finished sequentially, which means that the second rover might be 0, 0, N, which means the rover is in the bottom left corner and facing North. M means move forward one grid point, and maintain the same heading. The rover's current coordinates are (0, 4) and it is facing S Your code is pretty solid. Include movement commands for your hazards as well. The first line gives the rovers position, and the second line is a series of instructions telling the rover how to explore the plateau. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. In the previous step, we set our game objects in motion, but our rover and the hazards should be moving differently. correctly sets the value property in the new object.
