Unit

Units are groupings of functions and also variables. They can be thought of as modules or namespaces. A Mezzanine script must have at least one unit. Units are defined as follows

 

Info
  1. unit MyUnit;
  2.  
  3. string myVar;
  4.  
  5. int factorial(int x) {
  6.     if(x == 0 || x == 1) {
  7.         return 1;
  8.     } else if (x > 1) {
  9.         return factorial(x - 1);
  10.     }
  11. }

 

This unit has one unit variable named myVar. This variable has unit scope and can be accessed by any function in the unit. The unit also has a function named factorial. A unit must have at least one function. To refer to a unit’s member functions or variables from another unit, you have to use the scope operator

 

Info
  1. unit TestUnit;
  2.  
  3. void test() {
  4.     MyUnit:myVar = "New string value!";
  5.     int f = MyUnit:factorial(5);
  6. }

 

Note: Unit variables cannot be in line initialized when they are declared. The following code will not compile

 

Info
  1. unit MyUnit;
  2.  
  3. string myVar = "some value"; // this is not a legal statement
