Lua classes

How to create Lua class and how to use it?

[Kernell]

Lua does not support classes by default. But you can make a pseudo-classes.

If you want I can give his library to implement the classes.

[Kenix]

You can create pseudo-class with metatable.

Damn .. dont understand it. Any examples?

[Castillo]

As far as I know there are examples in that link.

Class Lib: http://pastebin.com/RC1gN4Bs

Class Vector3 for example: http://pastebin.com/WSgK0qFq

Example:

  
pos1 = Vector3( getElementPosition( element ) ); 
pos2 = Vector3( getElementPosition( element2 ) ); 
  
outputChatBox( "Distance between 'element' and 'element2' = " .. pos1:Distance( pos2 ) ); 
  

The Vector3 has operator overloading:

op  name  example

+     Add         v3 = v1 + v2

-      Sub         v3 = v1 - v2

*      Mul          v3 = v1 * v2

==    Equality      if v1 == v2 then ... end

..     Concat        outputDebugString( "Player pos: " .. vec )

K thanks. I know there are examples but it's more easier to uderstand when any user who is scripting try to explain it.
