My Max Items Script v1.0

[RPG~NOOB!!!]

My Max Items Script Version: 1.0
By: Jarviar also know on some rpgmaker sites as RPG~NOOB!!!

Introduction

This is a nice little script that let's you select the max number of each item. It comes with two parts the first is the main code and the second is plugins for the default shop screen.

Features

• Customize the default max for items with Maximums_Items = n
• Customize the default max for weapons with Maximums_Weapon = n
• Customize the default max for armor with Maximums_Armor = n
• Set the max number for a specific item with Item_Max[id] = n
• Set the max number for a specific weapon with Weapon_Max[id] = n
• Set the max number for specific armor with Armor_Max[id] = n
• If your using my shop extension it'll change the 'number in possession #' to 'Owned: #/Max'

Screenshots

Will try to post one if requested. But all it would be is the inventory screen or the shop screen.

Script

Here's the script. The first script is the main one the second is an extension for the default shop window if you want to use the extension past in the bottom of the first script..

Instructions

1. Place script above main.
2. If you don't want the shop extension delete from the line with # SHOP EXTENSION \|/ to the end of the script.
3. Read comments and customize.

Compatibility

Works with or without SDK!
The main code works with about everything but the shop extension WILL mess up custom shop systems. If your using a custom shop system then dont use the second script..

Credits and Thanks

Me/Jarviar for making.

Author's Notes

Sorry if this topic is kinda cluttered this is the first script I've uploaded. And I've noticed that in rpgmaker if you have a weapon in hand and dont have enough slots for it in your inventory then it just disappears.

Terms and Conditions

Remember to give some credit to me. Other than that enjoy.

Hey Jarviar.

Please wrap your code in [RGSS][/RGSS] tags instead of only using a spoiler.
As a result of not using those tags your indention is ruined


I deleted this post since I edited the tags into the other post.
I thank the forum for preserving the indention <3

 

[Rya]

I am surprised there is no response to this topic yet. It's a very nice, handy little script for those who feel 99 items is too much. I like it, and will most probably use it. Giving credit, of course.

 

[Kain Nobel]

I haven't had time to test and review this script, but reading it over I see a few things wrong with it or at least a few things you could do better... I'll show you an example, since you're using Hashes (my specialty)

I see...

Item_Max = {}
Maximum_Items = 10

I'm assuming the second value is the default of the first, correct? An easier and more effecient way would be...

Item_Max = {}
Item_Max.default = 10

This is basically how hashes work with a default value...

Spoiler: Example

Item_Max = {}

Item_Max[1] = 10

Item_Max[3] = 30

Item_Max.default = 99

p Item_Max[1] #=> 10

p Item_Max[2] #=> 99

p Item_Max[3] #=> 30

p Item_Max[4] #=> 99

p Item_Max[5] #=> 99

If you notice, 2, 4 and 5 weren't pre-defined... Item_Max.default was set to 99, so they'll return the default value

I also see alot of this...

      if Item_Max.include?(item_id) and Item_Max[item_id] != nil

        @items[item_id] = [[item_number(item_id) + n, 0].max, Item_Max[item_id]].min

      else

        @items[item_id] = [[item_number(item_id) + n, 0].max, Maximums_Items].min

      end

There is a concept called DRY (ie, Don't Repeat Yourself), there are few cases which you must repeat similiar or same coding but alot of times you can cut alot of repetitiveness down by making a common method for things like that. Although not absolutely necessary in this case (maybe), you might want to figure a way to cut back on the repetitiveness.

Even if this is one of your first scripts, it looks like you did alright on it (probably better than one of my first scripts), if I can I'll try and find some time tomorrow and see if I can test it out and help you clean this up a little bit.

Happy scripting :thumb:

 

[RPG~NOOB!!!]

Thanks for the replies i kinda forgot i posted this. And thanks for that info for the hashes I'll try it out.

 

[silver wind]

Can I set a max amount for 1 item using this script, and keep the others with no maximum?
Also why do you call yourself a noob

 

[RPG~NOOB!!!]

Yes. Heres some info from the scripts comments. If you have anymore questions go ahead and ask.
# # Maximums_Items = n
# # The default max number of items allowed in the players inventory at once.
# # Maximums_Weapon = n
# # The default max number of weapons allowed in the players inventory at once.
# # Maximums_Armor = n
# # The default max number of armor allowed in the players inventory at once.
# #
# # Item_Max[i_id] = n
# # The max amount of the specified item allowed in the players inventory at once.
# # Weapon_Max[w_id] = n
# # The max amount of the specified weapon allowed in the players inventory at once.
# # Armor_Max[a_id] = n
# # The max amount of the specified armor allowed in the players inventory at once.

You should also check the Shop scripts.

If you don't make any change on them you will be able to select up to 99 itens even if you can't carry. (you will not be able to get all of them, but you can select it)

 

[RPG~NOOB!!!]

Their is an edit for the default shop just look.
