Loading Variables into Objects

[killerogue]

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.

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_".

} 


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()?

[killerogue]

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)
      }

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.

[Rapidwolve]

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_'
  }
} 


[killerogue]

*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.

[Rapidwolve]

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.

I believe so, yes.

[cbk1994]

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();

[Inverness]

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.
