As I said in the last step, starting the line of code with a return type (like that int keyword the example above begins with) tells the computer that you're making (or declaring) a new variable. Currently i am using the list method to display and create individual values for each role. That means all of our code will need to keep repeating until a certain requirement has been met. Please refer to top-down movement, fighting mechanics and tilemaps system posts for more. Those are called variables. how do you know the variable doesn't change?
