Hard question for me... I guess if dll has their offsets, it may show them.. but not current yet

It's ok, thanks for your help, i'm not too expert with lua language, i know a bit better c#

I'm looking for a really deep lua guide, where I can learn all the returns calls and other advanced commands like string search and so on, if anyone can find a decent one - didn't find one yet sadly - feel free to write me

I have programmed in many scripts in other games, like even in L2Walker and the powerful ZRanger (used in L@ again).

I kinda find AS scripting very hard to understand or follow, it is like it has less structure than other scripts. I also specialized in C and C++ in the university, so I am pretty familiar with it and my final project was simulation (which is one of the tough things to do in programming, like AI)

I can understand most existing scripts (understand their functionality and what do I need to change to make a different thing) and I have done a few myself, but I just find it very abstract, like the example below:

Code: Select all

function OnLoad()
    for Item in ListIterator( InventoryList:GetList() ) do
        Write(""..Item:GetName().."  "..Item:GetAmount())
    end
end

It looks familiar, like a C++ (simple basic example below)

Code: Select all

for (i=0;i<10;i++)
{
    if(inventory[i]=="Potion")
        { use this or that
        }
}

I hope you understand, this has structure and has pointers and lists, and you set your variables as single ones, or table of contents.

I do not find these here, and there are other things like the double dots "..item:getname()" and what does "Item" stand for, is it a variable set by AS itself, do we have a pointer (like my example, "i"). I kinda find this pretty hard to follow, even for a IT graduate like me.

Look inside the main folder of AionScript for a file named AionScript.pdf

Item is instanced object of the Model Inventory.
For possible functions of the model look inside AionScript.pdf
If you are a graduated programmer read the manual dude really....
It tells you exactly InventoryList:GetList() returns an List of inventory objects.

You will find all things in there.

For your other question look inside Aionscript.lua what the function GetList actually does.

Yes I read the pdf but it simply has the names of functions and the names of preset variables. It doesn't say exactly how they are used.

I am a computer programmer but I do not know all languages, I specialized in C/C++

But you said that

InventoryList:GetList() returns an List of inventory objects

returns into where, and how do I find the object I need, don't I need this to be some sort of an array that has all 90 slots so I can look into a specific inventory[ i ] slot where "i" is a pointer I use to change the cell?

Nope, the C equivalent are linked lists, so you can't access it directly by defining the an key.
https://en.wikipedia.org/wiki/Linked_list
https://en.wikipedia.org/wiki/Doubly_linked_list

Code: Select all

for Item in ListIterator( InventoryList:GetList() ) do ....

would also work

Code: Select all

InvList = InventoryList:GetList();
for Item in ListIterator( InvList ) do ....

or

Code: Select all

InvList = InventoryList:GetList();
MyInventory = ListIterator( InvList );
for SingleItem in MyInventory do ....

returns into where, and how do I find the object I need, don't I need this to be some sort of an array that has all 90 slots so I can look into a specific inventory slot where "i" is a pointer I use to change the cell?

Just see how linked lists work.
You always have to iterate over all entries and you do exactly the same here.

Oh yes I am well aware of linked lists, floating in non serial way so you have to go through each cell from start so as to find the next one. Thanks for the input.

I know I will never be good in lua since I kinda find it a little less structured than C/C++ that I am so used. But this clears things up.
