Don't read much further in this user guide until you work on the tutorial. You will know if you have worked on it long enough when you understand clearly each of the following points. Swarm has many classes to make the modeling job easier. Swarm handles memory details. Those commands exist, but they exist inside the Swarm library, and they are accessed on behalf of users who use create or createBegin and drop to access memory for objects and get rid of them.
Case is important.
You can use any name you like for the objects that are created as instances. In the tutorial, when there is a single instance of a class to be created, by convention, it is typically named the lowercase version of the class name, such as the foodSpace object which is an instantiation of FoodSpace . As in any kind of programming task, neatness counts. Classes in Swarm are created with methods that group together their jobs by functions. It is much better to write small methods, each of which accomplishes a relatively specific task.
