Inventory Limits Options

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

Hey Syn, Nice script you have here.

I'll just throw some ideas at you just for future updates you may want to do =D

-Maybe enable the script so that it can apply for every actor?

--Each actor has a separate inventory limit.

--Each actor carry their own inventory.

--Inventories have different weights therefore there is a weight limit for every actor/whole party.

Just some ideas you may want to put for future updates of this script.


Nevertheless, nice script Syn!

1- Should already work with Trickster's Multiple inventories, may have to do a wee bit of editing.

2- Same as one, just have to do some editing

3- I think I saw a script on CA, may be compatible

4- somethings I was planning in the future.

Is it possible to make the items count as 1 not if you have 25 potions you have 25 weight already?

[Ty]

Yes, if you do a few mods.

All you would do is add an IF branch before this:

CODE

# Item
    when 0
      if item_difference > @item_storage
        @item_count = item_difference
        gain_item(item_id,-leftover)
      else
        @item_count = item_difference
      end
    # Weapon
    when 1
      if item_difference > @item_storage
        @item_count = item_difference
        gain_weapon(item_id,-leftover)
      else
        @item_count = item_difference
      end
     # Armor
    when 2
      if item_difference > @item_storage
        @item_count = item_difference
        gain_armor(item_id,-leftover)
      else
        @item_count = item_difference
      end
    end

to check if the Item being added is a defined item in the customization, if it is then you skip the weight check. So basically, make a new array in the customization section and add an IF branch that is similar in style to the ones I have checking if the item capacity is used up. Then when the item_id is = a defined value in the array skip the check and add as many of that one item as you want, since they will all count as one.

[Roderick]

Sorry but i don't know how to script and such so could you tell me what i need to put above the part you posted.

[Zambaku]

Is it possible to make a message appear that says that the inventory is full and then you get to choose whitch item to drop: Something in the inventory or the new found item.

[blakerowe]

The script is really good. I have used it on 2 of the games i have made. Now if only i could come up with a banking system that would be kool
