//  Extended 2D Array (vJass)
//
//  present by kingking
//
//  How to use?
//  //! textmacro 2DArray takes PREFIX, NAME, TYPE, LOAD
//  Here is the textmacro to let you play with it.
//  PREFIX -> private/public/nothing
//  NAME -> the variable's name
//  TYPE -> the type of variable
//  LOAD -> Functions of hashtable to store and get data. For integer, you need "Integer".
//
//  Example :
//  I need a 2d integer array vars in my library!
//  //! runtextmacro 2DArray("private","XnY","integer","Integer")
//  I need another 2d unit array vars!
//  //! runtextmacro 2DArray("private","Creeps","unit","UnitHandle")
//
//  -Pros- :
//  1) Practically unlimited array index.(Max value = 2^32)
//
//  -Cons- :
//  2) Generate a hashtable on every 2d variables.

Extended Arrays are nice, but I don't see any use in it since I've never used something more than one Dimensional arrays.

Might be good to create a physics system or a Vector System, but other than that, it's completly... Useless?

I was playing around with the array. I found jasshelper's 2d array is quite limited. It does not allow me to have x*y > 409550. So, I did this little thingy for big 2d array.

 

[Romek]

This is useless...
It's just a wrapper for hashtables.

where would you need it in a physics system?

Well, in the First Array you would define and save X movements, in the second Y movement and in the third Z movements.

Think of it as a 3d Grid.
