Inventory Limits

Script Name:  Inventory Limitations
Written by: Synthesize
Current Version: V.1.00
Release Date: August 13, 2007

What is it?
Inventory Limitations is a simple script that aliases some Game_Party methods allowing the party to carry only a certain amount of items at a single time. In order to carry more items at one time the 'bag' must be upgraded, this is done by storing the Bag sizes into an Array and then calling the flag. As an example, if you use the default value size of 50 items, then you can carry 25 potions and say 25 high potions. Afterwards your inventory is full since 25+25 = 50. Oh and I indented it better then others, cookie please.

Future Plans:
I plan on expanding the script once I get some more time, things I am planning include:
- Create Windows & a Scene
- Add more Designer customization
- Add more features

Screenshots
I did not make any Window's or Scenes yet so that might be kind of tough at the moment...So instead of looking at screen shots, go eat some pizza.

-=What is it?=-
  The purpose of this script is to allow Item Limitation, or in other words
limit the number of items the party can carry at one time. By default,
the party can carry 99 of every single item in the database. With this script
the party can only carry 50 items (Default value) and every item in the database
affects this number. As an example, say you have 25 potions and 25 High Potions,
now your inventory is full and the party cannot collect more items. That is, unless
you go out and buy a bigger bag.
Bag sizes are stored in an Array and called on by a flag. So virtually,
you can have as many items as you want, but you need a bigger bag to accomplish that.

-=Future Additions=-
- Make Custom Item Scene which displays Total Space and etc
- Most likely add more features

Another nice script. Just as a question, what windows and scenes are you thinking about? I've racked my brain for almost 1 minute and can't think of what it would be,

They would be rewrites of Window_Item and Scene_Item which will make them show some of the features I have planned, such as a weight system.

I tried using this script and it works but there doesn't seem to be any way to prevent ignoring new items given to you, they just simply disappear, for example: if you go into a store with your item limit and buy something, you spend the money, but your inventory doesn't change at all, and if you are given an item from an event or monster it simply doesn't enter your inventory. If you know of any way to prompt throwing out old items or how to make a trigger or conditional branch that triggers when you have a full inventory please reply.

intresting i have such a request for a script here
http://rmrk.net/index.php/topic,35671.msg428775.html#msg428775
perhaps you can up date me if and when you do so?

I think you need to calm down on your posts in here. I don't really mind since most are decent feedback and I suppose some of these scripts could use a lift, however, if you have questions with the authors or something and it's been over a year since the last post, much less the first post, send them a PM or Email instead. It's possible they're not as active or not active anymore and won't get this post unless they have it set on Email Alerts or something. Just try to avoid useless necroposting, which is where I see this heading.
