Limited Item Amounts?

[iskillzi]

Hello, I was wondering if it's possible to be able to have X item in a shop processing event then if someone buys the item it'll make it so they can't buy any more of that same item so long as they have their one.

This is definitely possible, but you either need one of the shop scripts(I'm pretty sure they have this option) or you need to create the shop yourself through eventing.

You can easily do this WITHOUT a shop, unless that won't work for your story. Just have a character selling the item:

if ___ item exists in inventory

"You can't buy it!"

else

+1 item

-50 gold

end

(or whatever)

Yea this is how I was doing it, I just figured since in this test game it has a LOT of items that change what happens in the game simply by having them so having to set this up for each and every one of them will take a very long time which is fine but it also means I'm more likely to make mistakes in the event script

Okay, then definitely check out some shop scripts. I know some can limit the shop inventory, but that's not what you're looking for. You may have to modify a script, or request one. It shouldn't be too hard, though.

I've moved this thread to RGSS3 Script Requests. Please be sure to post your threads in the correct forum next time. Thank you.


Please take a look at some of the existing scripts.

There are indeed existing scripts for it I believe. But here is a simple free one:

Just set the specific item max_value to 1.

I've posted this yesterday : script. No configuration module, but I don't really know if it's what you need.
