Tracking quantity of a particular item?

[christi]

I've finally started playing with my custom levelling system again... let's see if my brain's too fried to explain my problem in a logical fashion.

I need to figure out if there is a premade variable for keeping track of the party's quantity of a certain item. I've found one to keep track of how many items the party has total, but that's not going to work. I'd like a script branch to execute if the party member has at least one or more, let's say Snake Talismans. If the party doesn't have any Snake Talismans at all, a different script would execute entirely.

I realize I could create my own variable, and manually add and subtract from it when the party gains/uses a Snake Talisman, although I'm not sure how to handle this when, for example, an enemy would drop a Talisman. I'm not all that proficient with battle scripts. It'd just be a lot more convenient if there were a premade script that would track the quantity of Snake Talismans the player had, using the Item Database Number or something.

I tried using a page condition to set this up, too... if the party had a Snake Talisman, one script would occur, and if the party didn't have a Snake Talisman, another script would occur. This worked fine for awhile, but I'm controlling this with one script, and if the number of Snake Talismans drops down to zero, it's not going to switch pages in the middle of the script, so I'm really wanting to do this with a script branch condition instead of a page condition.

Hope this made sense... this levelling system is a real headache, but I really think it'll be worth it if I can get it all figured out/working properly.

Well, I can try to help. Lemme see if I can help you.
I remember you said something like there would be a screen that showed a screen with a circle similar to FFX's level circle. Except they would be talismans right?

Oh, well... uh... I guess I'll wait till your on huh...

This is easy once you know how to. ;D

You do:
Data: Variable: Item Number = 0 + [the item database number of this item]
(note that it's a good idea to make this item early in the list so it's number doesn't change, or make place holder items that aren't working yet for other things etc.)
Data: Load Game Info
Script: Condition: Variable: Total Items > 0 + 0
(I'm not sure of the exact variable's name since it's been a while, but press start on all the ones involving items and find the one that should be the number of that item the party has)
blah blah
Script: Condition: End

I'm not 100% sure those are the exact commands, but it is something along the lines of setting the Item Number variable to the number of that specified item, loading info to find how many of that item the party has, then doing a condition with the amount they have.

Happy to hear you're making good progress.

Edit: Also, this only tracks items in the Bag, so tell the player to keep them in the Bag or something. It gets much, much more complex and lengthy when you involve items on party members too.

Yes, Variable 80 : Total Items is the variable to use if you want to find the total number of a specific item in the bag (as opposed to Variable 79: Total Bag Items which gives the total of all items in the bag.)

You can use the Confirm Party Item command to turn on Flag 111: Has item if you only need to check if the item is somewhere on a party member, but this won't tell you who has the item or how many they have. Confirm Member Item does the same thing, but for a specific member. This is fine if you want to check if the member has the item needed to level without worrying about how many of the item he has. Removing the item from the party is the tricky thing that might require a lot of scripting - although requiring the currect active character (use the Data : target : possessions : Item command) or the bag (Party : Posessions : item) to have the item will simplify this.

Good luck.

you can also just load it into variable 80 and use the 'item action: use' command. this decreases one from the item database. i think thats the easiest way to do it.

[christi]

I just tried this out, and I think it's going to work.

I loaded the Item Number into Variable 134: Item Number, and then used the Confirm Party Has Item command. I set up a script condition with Variable 80: Total Items that causes one thing to happen if the party has the item, and another thing if the party doesn't, and it seems to work just fine.

On a related tangent: I've pretty much come to the conclusion that I don't like the default menu. Allowing the player to take an item from the bag and give it to a party member really complicates things. If the player were to do this to a Talisman, it would completely negate this script's effectiveness. I think I'm going to get rid of the default menu altogether; all I really like about it is that you can see the party's stats and items. I could probably figure out how to make a screen like that on my own (well... with help, anyway). I'm thinking it'd be worth it to get rid of that default menu.

[vespuleth]

the only problem is that if you do, you have to simulate items, and direct effects. it pretty much makes both databases useless (not using the default menu, that is). ive really stumbled through this problem lately. still lookin for a workaround.

[christi]

I remember reading a post about that earlier; it sounds like it'd be a pain.

I'd like to scrap the default menu someday, although I doubt I'll be up to it any time soon. At the very least, I'd like to figure out a way to just use the bag, and not allow the option to "give" things from the bag to a certain party member. Would something like that be any easier?

It depends. If you have a low number of items and party members it wouldn't be impossible like it would with what I've made so far. The default menu's moving items around is annoying but it gets a lot nicer once you take out all the messages ( doansdomain.proboards27.com/index.cgi?action=display&board=Games&thread=1106517326&start=15 ).
