Lua of OOP programming

 

 

 

 

 

 

 

 

Field and method tables

 

 

 

 

- of OOP programming essentially lua using analog table to 
- define empty table, a class quite 
the Person = {}
 - defined fields 
person.name = " Kun " 
Person.Gender = " M " 
Person.Profession = " CS.GO " 
Person.Height = 170. 
- definition method 
Person.Speak = function ()     - anonymous function definition 
    print ( " Kun build-up of so many ah " )
 End 

function Person.Walking ()    - common define 
    print ( 'Kun is Five " )
 End 

function Person.ShowInfo ()
     Print ( " call my personal height " )
     Print ( " Height: " ..Person.Height)
     Print ( " Occupation: " ..Person.Profession)
 End 

- call field and method 
Print (person.name)
 Print (Person.Gender)
 Print (Person.Profession)
 Print (Person.Height)
 - calling method 
Print (Person.Speak ())
 Print (Person.Walking ())
 Print(Person.ShowInfo())

 

The introduction of local variables to reduce coupling procedure

 

 

= The Person {}
 - local people the Person = 
- defined fields 
person.name = " Kun " 
Person.Gender = " M " 
Person.Profession = " CS.GO " 
Person.Height = 170. 
- define methods 
function the Person: Speak ()     - the anonymous function definitions 
    Print ( " Kun's build-up really, ah " )
 End 

function the Person: lettin ()    - commonly define 
    Print ( " Kun is Five " )
 End

function the Person: ShowInfo ()
     Print ( " call my personal height " )
     Print ( " Height: " ..self.Height)
     Print ( " Occupation: " ..self.Profession) 
    self.Speak () 
    self.Walking () 
End 

- to improve the function definition mode, use the self keyword (with the function uses the 'colon' defined functions) 
function the person: Show ()
     Print ( " call my personal height " )
     Print ( " height: " ..self.Height)
     Print ( " Occupation:"..self.Profession) 
    self.Speak () 
    self.Walking () 
End 

A = Person   - will be assigned to Person A 
Person = nil     - the destruction of Person pointers 
a.ShowInfo ();    - continue to call the original method, However, you can call any
