Note the slight difference: We use a colon instead of a period here. This is typically used for non-static functions (functions which rely upon the state of the class, or the variables inside the instance of the class, to determine their operation). This is needed because we need to know the variable "race" inside our instance. This determines whether the function returns true or false.

This is needed because we need to know the variable "race" inside our instance. This determines whether the function returns true or false. The use of this colon states that, when this function is called, a [[Lua Scope#Function-local Variables|function-local variable]] will be created. The variable will be named "self" and is a reference to the instance of the class. Thus, we can use the variable "self.class" to determine the class of that one particular character.
