Inventory Limitations

Draconis Inventory Limitations v1.2 by DraconisKnightIntroduction: I made this plugin for my own project after finding other limited inventory plugins, such as the one by Mr. Trivel. I couldn't get how I wanted my inventory to work since I was wanting to use a variable and items to control my max limit. With Inventory Limitations, you can use variables to limit and adjust the cap with usage of items. All it takes is setting your variables up and events that either increase or decrease the max limit. Features: - Limiting your party's inventory with $gameVariables - Making it were a stack can equal a space with the Exempt note tag Three options: Numerical, Mathematical, and $data Numerical: and makes all items in that stack count towards the inventory cap. tells the plugin not to count that item. This one is best used on key items. Mathematical: $gameVariables.value(i) would equal the variable assigned to the number of that particular item the party has in possession. The minus one in the equation will deduce one item for the inventory count. The rest will be exempt. $data Added to the help file by Zarsla. They use data straight from the database. To use this option, use the following note tags as each will be for their respective category in your project database. or or or Note that will be the object's index your database. And use the square brackets around i. -Some customization to Scene Shop after adding inventory count to the status window. Inventory count can be set to show used space over the total space (inventory cap), only the remaining slots available, or the remaining slots available over the inventory cap. - Script call: $gameParty.getInventUsedSpace (); => Returns the occupied space. Can be used in your events to see if the party can carry anymore new items/item stacks. Setting up Inventory Limitations: (Added 6 March 2018) Install Draconis_InventoryLimitations.js in your Plugin Manager. If you are using Yanfly's Item Core, make sure Inventory Limitations in under it. Follow the help file with the parameters. The only one that does not need input is "Exempt". On your first map, make a parallel process. All you need to do here is assign variables: one for the inventory cap (if using the variable method) and several more for the number of X items the party has. Those variables will be used in the math version of the Exempt note tag. EX: 10x Potions Event Page will have Control Variables: #001 Potions Exempt = Number of Potions In the items tab of the database, select potion and enter . Screenshots: Attached. Downloads: Download plugin only here. Download Demo Project here. Terms of Use: This plugin is free to use for both non-commercial and commercial use. All I ask is credit for using this plugin. Also credit Zarsla as they added a new gain item function to the plugin. Modifications are fine as long credit is given. Thanks goes to: -Mr. Trivel => Author of MrT_LimitedInventory as it started my coding journey. -Yanfly => Whose plugins I picked apart and reverse engineered while also reading the core files. -TheoAllen => Author of a weight based inventory that was also studied for version 1.1. Compatible with: -Yanfly Core Engine -Yanfly's Item Core without Independent Items engaged. Upcoming Features: -A non-stacking inventory system with its own discard and discard confirm. [Current Project] -A way for those using a static inventory cap to increase if they wish -[Finished: April 2018 to January 2019] Discard works for all item categories with the exception of Key Items. -[Finished: July 2019 to January 2020] A confirm window before the discard to help prevent accidental discarding. -Layering windows because MV just overwriting it looks tacky. Purely for aesthetics. -Possibly adding a speed option. Maybe after tinkering with the concept. Note: - I just noticed a small bug with if you are awarding one item (such as a potion), I'm already working on a fix. But it works fine if you award more one. (Resolved- Help file expanded on how to avoid this.) -Item Limit Window refreshes after opening the item menu if using YEP_X_ItemDiscard. (Resolved between April 2018 to January 2018. The plugin now has its own discard function that YEP_X_ItemDiscard isn't needed. Within the discard function, this plugin updates the limit window automatically.) -Any bought item (that exceeds the inventory limit) is automatically deleted. I still want to address this in the plugin, but after hitting the JS books and taking time to understand how the shop functions work. (Resolved April 2018 by overwriting the shop's…

I'm having trouble understanding the exempt tagging - it seems backwards compared to other item limits?

So if I wanted something to weigh X units, how would i tag:
- some heavy item that weighs 2 or 4 units all on its own
- something that weighs 1 unit per 4 in a stack
- something that weighs nothing at all, no matter how many are in a stack

The exempt tag is for how many of an item is not counted towards the inventory cap. For example, the player can have 15 potions. If the exempt tax is set to the number of potions in possession minus one, the plugin recognizes the potions take one slot in the party's inventory. (Think along the lines of Harvest Moon, Story of Seasons, and Monster Hunter where the player is limited by how many item slots they have.)

I don't have a weight system implemented as Theo Allen released his Theo - Limited Inventory (for MV), which is a weight based inventory system. (As I'm not using a weight system for my game.)

I'll tinker with it as soon I can as I'm itching to work on the plugin again. But it may take awhile as I'm tackling a few things outside of MV.

Fixed a minor bug in the shop's isEnabled function. Party members can now buy items that they actively carry in their sack when all the stack slots are full.

Sorry about that.

Heya @DraconisKnight, I'm checking out your plugin because I think it will be perfect for one of my projects. However, I've found that the demo project you have uploaded has a bunch of plugins enabled that are not included with the project, and also your plugin itself is disabled. I had to go in and remove all the plugins except for yours to get the project to run.

Hope this helps!

EDIT: Also, your throw away function only throws away a whole stack, while Yanfly's ItemDiscard allows the user to choose how many to discard. It would be useful to allow the player to choose how many to discard in your action window, otherwise it would be nice to be able to disable your action window so that I can use ItemDiscard instead.

EDIT2: After doing some testing, it seems that if an event gives a player another item that they already have while inventory is full, it will reset that item's count to 0, effectively deleting them all and freeing up inventory space. If the game attempts to give the player an item they don't have while inventory is full, nothing will happen. Do you have plans to perhaps handle this situation via the plugin so that we don't have to use conditional branches to check inventory space beforehand?

Just finished and happy to say that I'm releasing 1.2. It has a new discard confirm window for a stacking inventory along with the command to jump to Scene_Equip along with the option of changing the new window's opacity.

@Kest I'm sorry that I just noticed the bug with the Item Limit window text. Fixed.

@Evren Sorry for now just seeing your message. I don't remember getting the alert for it. And thanks, I forgot to delete those last time as I have them in mine to test for bugs/compatiblity. (Remember to delete the extras this time.) Now, to the questions.

I can try implementing a way for someone to choose how many items to discard. Right now, it is planned to where stacks will be discarded assuming the inventory is set up as a 'slot' with the Exempt tag exempting all but one. This is something I'll be tinkering with now that I have the stack discard figured out/ironed out. (Hopefully, with one system written, it will be easier for me to figure out the other. Future 1.3 most likely that I will try to have out a lot sooner than it took me to iron out this current version. :kaosigh:)

But, a heads up with this plugin and Yanfly's ItemDiscard is that I never figured out how to refresh the Item Limit Window via a patch in mine or a separate extension of theirs. As such, the only way to update the Item Limit Window is through exiting and reentering the Scene_Item.

On the items, I'll have to look at the gainItem function Zarsla wrote. They wrote it where the plugin will check if an item can be added or force discarded. Which is a concern now that I'm in the mood to iron out the non-stacking potential.

If the item is using the <Exempt: ($gameParty.numItems($dataItems[x]) - 1)> (or $dataWeapons/$dataArmors), it is just fine. But I see what you mean with an item using <Exempt: 0>. Initially, I personally planned on using conditional branches for space check along with a plugin like Yanfly's Core Engine with a Max Item note tag to help. With the check in the event, I could suggest checking one's pack if the pack is full. But, I'll definitely look into items already in possession with <Exempt: 0> and the gainItem function.

Thank you again. :)

Hello, I'm having trouble understanding how to use this plugin. I want to set specific limits to specific items. For instance, say I want the player to only be able to hold 5 Elixirs, 30 Potions, and 30 Ethers max each. Is this A) possible with the script, and B) how might I go about achieving this?
Thank you in advance for your time and consideration.

@Diretooth This plugin does not alter the max items per item the party can have. Only how big their pack is.

I've tested this with Yanfly's Core Engine plugin, in which a note tag for Max Items. I think there may be a few other plugins that do as well that I need to test this with. (I think.)

I hope this helps. :)

@Bilalichwa How is your database set up? I come across this if I forget to put the exempt tag in the note box of the item, weapon, or armor.

And that is because right now, it is including the note tag in it's calculation for used space.

This is a fantastic plugin. I do have a question though. Is there a way to set a variable to equal the number of items in your inventory? I'm looking for a way to keep players from
picking up items if their inventory is already full.

I have managed to configure everything. But I have a problem. When the inventory limit is reached, the stack of objects is reset to 0, losing all of them. You say you fixed this bug, but I don't know if I have to add something to the game to make it work properly.

@Angelus197 I remember looking into that plugin wise. Otherwise, I recall the solution being an if statement in the event.

I'm sorry for that late reply. But I haven't haven't touched the plugin in a long while, so I don't know when I will get the next update out.

Hey Draconis, this is a great plugin, though I'm having an issue with compatibility. I am willing to pay somebody to make a fix,
I made a post about it please take a look if you have the time.

MV - Creating actor specific and limited capacity inventory, mostly done just need some help please
Also on a side note I am wondering about the possibility of being able to assign items a weight with a note tag, your plugin is far better than Mr.Trivels simply because of the compatibility with yanfly item core, among other reasons, but my real goal is to be able to assign weight to items. I would be willing to pay you for any time it would take to add this functionality. Anyway, thank you for your great plugin and have a great day
