Assets [WIP] Rucksack - Multiplayer Inventory System

We've built Rucksack with the goal of being the most flexible and extensible inventory solution with UNet support that enables you to easily setup player inventories, NPC inventories, banks, premium shops and much more! So, what does this mean?

It means that Rucksack is a super extensible system with full source code, a modular event based UI system, multiplayer built-in with UNet integration, a network permission model with server-based authorization, and much more!

We're on a mission to build the best modular multiplayer-ready inventory system on the market, using all the knowledge we've gained over the years on the Asset Store - and we're very hyped about releasing what we believe to be the best tool we've ever built!


⚔️ Main Features ⚔️


Multiplayer-compatible with UNet integration:

With a built-in integration for UNet that allows you to integrate into any server/networking setup, Rucksack is perfect for both online multiplayer and singleplayer games. Rucksack is secure and uses a server-authoritative permission model; So, no cheaters!

Modular event based UI system:
You’re in full control of your UI with our modular and event-based UI system. The system is very fast and extensible, yet simple to use, which means you’ll be setting up your inventory / collections UI in no time! It doesn’t matter if you’re making a fantasy RPG or a casual mobile game with IAP - Rucksack’s UI system can handle it all.

Items with behaviours:
In Rucksack, items can have behaviors, and you can very easily make your own item types and add custom behavior. We won’t limit your options!

Restrict collections:

Need a quest items-only inventory? Or a consumables-only inventory? Not a problem for Rucksack; Use any metric to restrict the objects that can be stored in a collection.

Insanely extensible:
Rucksack has been built from the ground-up to be extensible in every possible way, ensuring that you’ll never be limited in what you can achieve with the system if you want to extend it.

Visual item equipment / NPC’s with equipment:

Any character in your game can have their own inventories and equipment, which means you can make them equip different weapons and gear by simply binding it onto the NPC (static, skinned, and dynamic cloth meshes, or write your own equipment handler).

Permission Model with server-based authorization:
Our server-based authorization model makes your game cheat-proof, while remaining flexible and extensible to fit every kind of server / network setup. Example use with UNet: UNetPermissionRegistry.collections.SetPermission(collection, player, Permission.Read).

Vendors can sell anything for anything:
Need to be able to sell houses for cats, or skill for skillpoints? With Rucksack, any item can be sold, and anything can be a currency. Go nuts!

Shared and non-shared (instanced) banks and chests:

With Rucksack, you can easily differentiate between and setup both shared and non-shared (instanced) banks and chests in-game. The system is so flexible that the shared banks and chests could theoretically be shared between every player in a game, everyone in your party - and everything in-between.

Modular input and UI system:
Rucksack’s modular input system is extensible and changeable, and allows you to create input modules to handle your input. The beauty is that you can very easily replace or swap out certain input modules for maximum control (example).

Item inheritance:

Want to reduce the data transfers in your online game? With item inheritance, you can create variations of items (e.g. a Sword that can also be a Fire Sword). With Rucksack’s inheritance system, the Fire Sword can inherit its base stats from the Sword, while only overriding or adding those properties that have changed or have been added. In a large game, this saves a lot of duplicate data of unused props from being transferred.

Different prices at vendors for different users:

You can easily achieve and setup different prices at vendors / shops based on whatever properties you want, such as different in-app purchase prices based on country (requires custom IVendor<T> implementation).

Thanks to everyone who helped beta test, and we hope you're as excited as we are about Rucksack! Got any suggestions or feedback? Let us know below

- Your friends at Devdog (Joris and Sune)

 

Superb stuff, Can't wait to get my hands on it. (insert Futurama meme here)

 

Finalllyyyyyy <3

 

After playing around with networking inventory pro, I've been watching on the Devdog Discord for this release! Can't wait to see an UMA integration @SecretAnorak ^^

 

Oh trust me, I'll be on the case immediately

 

Looking forward to getting my hands dirty on this right away

 

Oooooooooooooooooooooooooooooooooooooooooooooooooooooooooh sweet.
LoL 3yrs worth begging and its here!! Well worth the wait

 

Looks very cool and promising asset! thumbs up

 

Really hope you'll enjoy it! Can't wait to hear what you all think about it.

Videos and more will be coming soon too.

 

Does it support offline mode? Please compare with inventory pro in detail.

 

Yes, it does, it just also happens to have really good support for online play.

http://rucksack-docs.readthedocs.io/en/latest/

 

Is it possible to make this asset work with other networking solutions? Or is UNET required?

 

I've split of as much network code as I could into a general non-unet dependent namespace; So it can be re-used for a photon integration - or anything else.
You're not forced to use UNet - it's just what we provide a standard integration with. All of Rucksack has been built to be extendable and customizable.

An actual comparison chart is actually a good idea! Will consider that.

Rucksack is superior in every way to Inventory Pro and ultimately will aim to replace it (although in a separate package). Rucksack will be cheaper than Inventory Pro, but also lacks some features compared to inventory pro (no crafting, skillbars), as we aim to keep rucksack as clean as possible and build on top of it through addons / separate asset store packages; For example a mobile package, RPG pack, survival pack, etc

We aim to keep Rucksack clean and simple, yet powerful, so the community can build their own specific addons they might need for their game, rather than cluttering up the core inventory system.

On our new website, which will go live very soon, we'll also have a section for addons where we will share these community-built addons.

 

Do you provide character stats? If so, I would like to support something like the status value curve generation.

 

Hey guys. Using your inheritable item feature, can we have item qualities? For example, in inventory pro you had to have one hundred different items if I wanted 100 levels of quality (plus a specific crafting recipe for each). For this one it sounds like I can have one item, then modify a quality stat as needed. Does that sound right?

 

We don't include character stats by default, however, you can very easily implement your own stats system. See: http://rucksack-docs.readthedocs.io/en/latest/APIDocs/CharacterEquipment/EquippableCharacter/ for the docs on how to create a stat character

 

You could certainly do this. The item inheritance feature applies to item definitions only (see http://rucksack-docs.readthedocs.io/en/latest/APIDocs/Items/Items/#item-definition). You can either create the 100 items (lots of work, obviously), or, you can deterministically generate them at run-time

 

Finished two getting started videos.
Now we're really just waiting for Unity to accept Rucksack

 

It's aliiiiive!

@jorisshh - Will the upgrade pricing be permanent, or is it for a limited time only?

 

We want to keep it permanent, but have had to remove it right now because for some reason, when we had the discount enabled, Unity would show reviews of Inventory Pro on the Rucksack page, which is misleading as Rucksack is a new product entirely and has nothing to do with Inventory Pro.

We've reached out to Unity in the hopes to have this fixed, although it seems to just be the way the Asset Store works. Will give you guys an update once we've heard back.

 

Frankly, I am more interested in expansion packs. When will the expansion pack be released?

 

We don't know at this point. It's not something we've started working on, as Rucksack JUST released, and we'll be working on improving that through updates for the immediate future

 

That is indeed how the upgrade on the asset store has always worked. No getting around it.

 

I would like a discount on Rucksack because I own Inventory Pro and it looks like it’s going to get superseded by rucksack, and if it had been called Inventory Pro2 I would have expected a discount.

I also realise that Devdog isn’t a charity and needs to make money.

I like the “add-on” “plugin” concept because it is an incentive for devs to keep improving on the asset and still making in money from sales rather than dishing out free upgrades to existing customers for no profit.

At the end of the day we want great assets with support and ongoing development, and that costs money.

An I for one greatly appreciate the time thought and effort devdog puts into their assets.

I'd still like a discount though....

Mr tight git

 

@hopeful @nomax5

Sadly Unity doesn't allow us to do a normal discount for Inventory Pro users without copying over the comments. Therefore, we've decided to drop our already low introduction price of $35 to $29 for everyone in the first week (so from the 17th to the 24th). If you've already bought Rucksack for $35 and wish to get the discount you can request a refund and re-purchase it. We hope this makes up for it

 

I downloaded the asset. And I had to see a lot of errors.

Assets/Devdog/Rucksack/Demo/Scripts/TriggerAreaHint.cs(33,24): error CS1644: Feature `null propagating operator' cannot be used because it is not part of the C# 4.0 language specification

Assets/Devdog/Rucksack/Source/CharacterEquipment/EquipmentCollectionBase.cs(72,40): error CS1644: Feature `interpolated strings' cannot be used because it is not part of the C# 4.0 language specification

 

Rucksack requires .Net 4.6. See http://rucksack-docs.readthedocs.io/en/latest/GettingStarted/ for the docs (would recommend the video tutorials to get started)

 

There are four unresolved errors.

Are you using Unity 2017.3+? Included this in the docs and FAQ

 

I run mobileui_prtial

and I got errors

This is a visual studio error though? It doesn't seem to have anything to do with Rucksack or a game system for that matter. What version of Visual studio are you using?

 

it does and thats a nice gesture..

 

Hi, i have been used inventory pro but i found it to be always heavy on mobile. and had to design your game around it.

is Rucksack more lightweight and easier to integrate within your game ? does it still use Resources folder, to me its a big no to put all content in resource folder and end up with 30 sec + loading time on mobile

 

All data can be streamed in if you like (item data, vendor data, etc). This is a big change from Inventory Pro, where the data was fairly static and linked to unity objects. By default item definitions are stored as scriptable objects, which you can package in separate asset bundles to avoid long loading times at the start of your game.

And yes, Rucksack is considerably easier to manage and integrate into existing projects, as it's more lightweight both in drawing performance (UI) and general code.

 

I have encountered other errors in the mobile ui scene.
when I click add item


ArgumentException: No instance type found for definition Devdog.Rucksack.Items.UnityItemDefinition

In fact, every time I press a button, everything is error-filled.

 

Make sure you have a UNetItemFactory or a UnityItemFactory component attached to your managers. This is required to add the bindings to the item factory.

 

i just got this and it has lots of errors

Code (CSharp):

1. Assets/Devdog/Rucksack/Source/Collections/CollectionBase.cs(218,32): error CS1644: Feature `interpolated strings' cannot be used because it is not part of the C# 4.0 language specification

5. 8 similar errors on this script

edit:
posted too soon
fixed by changing player settings to .net 4.6

 

It would seem projects like Rucksack will need to put in a check of the project settings and throw up a huge red banner that says to change it if it's not set to 4.6.

 

Does this already have support and/or examples for Forge Remastered networking?

If not, when will it be available?

 

No integration with forge is planned. Someone is integrating photon (community effort). As of right now only UNet is supported.

There is, however, no core dependency on UNet, so it can be swapped out for another networking library, but this requires adopting the permissions system to the other networking library + creating new classes for collection replication

 

Hi, I'm interested in developing Game Asset Manager written in directly in Unity Editor. Odin came into my radar as the bases and I also ran into Rucksack. I think it would be really great that Rucksack item editor based on Odin. I'm not sure if Odin and Rucksack is developed by the same developer but why don't you use Odin? It seems like there are quite a lot of overlaps. It would really great if possible so that I don't have to use two different editor frameworks. Cheers!

 

Sure, that would be great but only if you already own both assets. It is typically a terrible idea to build an asset fully dependant on another paid asset because then if the user doesn't own both assets, or have both installed in their project, it is not going to work right. You can't use something made with Odin if you don't own Odin. Trust me, I wish that were not the case, lol.

 

Sure, I understand. Odin developer mentioned releasing Free version of Odin. We should push toward that direction so that Odin can be adopted not only by Rucksack but by many other asset developers. More power to you if you do. Cheers!

 

i just cant get it to work.
following the setup vid 1, i made the databases, gui and an item in the scene.
when i try to pick up the item i get

i have tried all sorts, any ideas?
thanks

 

Any news on a photon integration?

 

Please join our Discord channel at: https://discord.gg/zjNj5zZ - This thread is no longer maintained.

 

Are there any examples of how to integrate Rucksack with Ultimate Character Controller?

 

In the "

" tutorial there is the "U Net Inventory Player" script. This does not exist in the current version, which makes it difficult to follow this tutorial. Why do not you update this too?

 

Did I overlook something, or does rucksack still not support crafting? Inventory Pro (from the same developer) seems to do much more than rucksack (no multiplayer of course).

 

You definitely poured your heart and soul into this project. Can't wait to try it out!
