Loading Variables into Objects

Ok, here's what Im' doing, I'm loading variables from a text file into an object then I'm using a for each loop to go through each var starting with "whatever" like this"

PHP Code:


		
			
blah = new TStaticVar();

blah.loadVars("thistextfile.arc")

Now my questions is do I do this...

PHP Code:


		
			
for (i: getstringkeys("inv_"));

Or this....

PHP Code:


		
			
for (i: getstringkeys("blah.inv_"));

Forgive me if it's a really simple or unintelligent questions, I just sort of started understanding objects today and I figured this would be somewhat of a cakewalk. :P

(What I'm doing is creating an item system using text files. :D

getstringkeys() accepts this., thiso., player., playero. etc., you can't do "anyobjectname.varname" though. For that you would need to use the with-command like

PHP Code:


		
			
with (objectname) {
  for (key: getstringkeys("this.inv_"))
    ...
}

That's interesting. >.>

Seeing as how a friend of mine told me,

PHP Code:


		
			
for (key: getstringkeys("objectname.inv_"))

Would work.

Edit: But if I did:

Here's what I'm doing:

PHP Code:


		
			
public function inventory()
{
  invcontents = new TStaticVar();
  invcontents.loadVars("levels/player_" @ player.account @ ".arc");
    for (i: getstringkeys("inv_"))
    {
      if (i == "item=")
      {
        tokens = getstringkeys("invcontents.inv_" @ i).substring(22).tokenize(",");
      }
      else if (i == "wep=")
      {
        //stuff
      }
      else if (i == "keyitem=")
      {
        tokens = getstringkeys("invcontents.inv_" @ i).substring(25).tokenize(",");
      }
      else if (i == "clothes=")
      {
        tokens = getstringkeys("invcontents.inv_" @ i).substring(25).tokenize(",");
      }
    }
  } 
}

Also, doing what you said and using, with, would I have to put "this.inv_" or could I just do "inv_".

"inv_" really just refers to temp.inv_, inv_ (global), or player.inv_. Not "this.inv_", your method works because you're making the variable global.

It is bad practice in general, and you should really just use with ( item ).

By glancing at your script, however, you seem to be making things hard for yourself. Why don't you use the index numbers?

PHP Code:


		
			
        tokens = invcontents.(@"inv_" @ i);

Personally, I do not understand what you're trying to accomplish here.

getDynamicVarNames()?

Basically, I have loaded variables from a text file into invcontents.

There maybe one or more variables in the text file starting with the prefix "inv_" now, then it uses the for loop to go through everything that starts with, "inv_". After that it checks what text is after "inv_".

Like for example, in the text file I might have this:

inv_item=name,icon,power,blah

After I check if "item=" is after inventory or not or any of the other words after it, I'm creating a substring of everything after the "=" and tokenizing it to turn it into an array.

This is what I'm trying to do, put all the information in the text file AFTER the "itemname=" into an array.

What Stefan suggested, so something like this would be fine?

PHP Code:


		
			
  with (invcontents)
  {
    for (i: getstringkeys("this.inv_"))
    {
      if (i == "item=")
      {
        tokens = getstringkeys("invcontents.inv_" @ i)
      }

He's not trying to get the variable names hes trying to return whatever is after the 'inv_'

I'm trying to return whatever is after,

'inv_itemnamehere='

Like,

'inv_item=Name,ID,Icon'

I'm trying to get all that information after item, or weapon --which is represented by 'i'-- and put it into an array.

Hence like I said, everything after 'inv_', what your doing is right so far. Just use:

PHP Code:


		
			
with (findNPC("Database")){

  for (temp.i: getstringkeys("this.inv_"){

    echo(temp.i); // Returns everything that starts with 'inv_'

  }

}

*sigh*

I'm NOT using a database, it's an object dude, and I'm trying to return the information AFTER 'inv_tempi='. 'temp.i' stands for either "item=" or "weap=" and the information after the "=" is what I'm trying to get and pur into an array.

Load the arrays first

PHP Code:


		
			
temp.playerData = new TStaticVar(); 

temp.playerData.loadVars("thistextfile.arc");

for (temp.currentData: temp.playerData.getDynamicVarNames())

  if (temp.currentData.starts("inv"))

    temp.foundData = temp.currentData;

Then you would like to load the temp.foundData, with whatever. I think that should work

I really don't get this

TEXT FILE BELOW

[TEXTFILE]
inv_item=Name,Icon,ID
inv_item=Name,Icon,ID
inv_weap=Name,Icon,ID
[/TEXTFILE]

I load those vars from the text file into an object!
NOW,

OBJECT WITH BOLD
[OBJECT]
inv_item=Name,Icon,ID
inv_item=Name,Icon,ID
inv_weap=Name,Icon,ID
[/OBJECT]

Everything that's bolded and underlined, is what I'm trying to get from what I loaded into the object!

I loaded inv_item=blah into the object, now I'm trying to get "blah" back.

I'm not sure if that will work, your just overwriting the previous object. I would suggest 'item_id=Name, Icon'

._. ......I suppose that would be easier, and more sensible, wouldn't it.
Also, a more sensible question would be, if, when I load "inv_item=Blah,Blah1,Blah2" from the text file into the object, does it become an array?

E: Oh, it does! Thanks for helping, and sorry for flipping out on you guys. Just got quite frustrated. >_<

inv_item=Blah,Blah1,Blah2

If you meant something like

inv_item1337=id=1,quantity=1,foo=3

etc.

You could use getDynamicVarNames(); Use a str.starts(); and then use a ( "varname_" @ ITEMNAME ) = array;
then when accessing you could create a TStaticVar() and obj.LoadVarsFromArrays();

Putting the variable names are part of the item array data is very bad in my opinion. What I've done with more simple systems like that is set a serverr variable that show whats at each index:
serverr.itemvars_<typename>=id,qty,name,image,weig ht
clientr.item<number>=23,1,"Fancy Sword",fancysword.png,5000
Then you use function like getitemvar(id, varname) and return the item index that matches the index of the varname in the serverr string.

Edit: With the simplest system I would have the type of item as the first variable, then I would find the right variable list for that type with a function before continuing so all items didn't require a master list.
