As always, this asset allows you to integrate a very stable and highly capable inventory system with excellent quality. However, due to its overwhelming level of functionality, it can feel somewhat difficult to approach at first. I believe it would be even better if there were a step-by-step tutorial that guides users through building a sample project from scratch.

This is actually more than an inventory - the demo gets you started with a shop, crafting and recipe system, and the UCC+UIS demo even had small touches like opening a chest which opened a menu with options like 'Take All', or chopping a tree to collect wood. I had an issue integrating it with UCC and the team responded fast, over the weekend, and even offered to screenshare to get me up and running if needed. Can't recommend enough. Most of my games core frameworks come from Opsive (character controllers, behaviour trees, and now inventory). Slight learning curve, but incredibly powerful once you get your head around their systems., and there's lots of documentation/training videos.

I see the use of the asset it's a powerful tool. The main issue is the documentation is terrible. There's absolutely no version specific documentation. Overall, because of this I was stonewalled making progress with it. Things get moved during micro updates documentation isn't updated to reflect that rendering their documentation relatively useless. Emails were sent by a colleague requesting correct documentation and was replied to by simply being told they don't have it available.

After using this asset for quite some time now, it has become one of the major cornerstones in my game. The entire Item Definitions and Item Categories system integrates in the rest of my game far beyond just the inventory. Its like a mini database for every parameter an object in my game has and I relate to it from every component/system. After reading some of the comments below I must say that you cannot expect to use this asset as a drag and drop component in your game, there are far easier and simpler asset packs for this (also cheaper). And yes, I too have been frustrated at times on the documentation - it could use some more mini-examples in each category. The naming convention is just awkward at times - ItemSlotSet, ItemSlotCollection, ItemRestrictionSetObject, wha? But if you do take the time for it, it does eventually make sense. And at some point you do get the hang of it and it becomes a super powerful tool that integrates with the rest of your game. Its super flexible and its a solid base for everything regarding inventory/crafting/currency/UI. Now, every time I now want to add something new to the game, im more like "just adjust this and that in UIS and im done", as the systems are usually already prepared upfront by UIS.

I've searched the Asset Store to find an Inventory System that would provide all the features I needed, and none did, except this asset! And it's not that I have something complicated, quite the opposite, I just needed a simple inventory system and shop. But the other assets did not include some functionality and extensibility that were included in UIS. It's not that everything is ready out of the box to provide everything any developer needs for all use cases. That would really be practically impossible. However, it does provide all the building blocks you would need to adapt and customize it to your liking. The UI Designer system would be a good starting point for any project, and then, customize, extend, add, and adapt to your liking. However, to be able to do that, it is very important that one would need a good working knowledge of C# and OOP, except if the system that the UI Designer generates is enough. There's a lot of documentation and examples. However, I'd really like a lot more of both to avoid resorting to the Opsive forums for support. But whenever I did, I got the help I needed, and all problems were solved.

I own Behavior Designer and if this asset was as good quality as that one it'd save me hundreds of prototyping hours. Sadly it's not all the way there. This is a very robust and capable asset that does an OK job. If you need an inventory that is JUST LIKE the one in the demo it will be perfect for you. However, there are some clear architectural flaws that make this asset highly coupled and less flexible as a consequence. So if you wanna customize the logic for a shop, good luck digging through the code. I wish opsive made a re-write of this asset because I think the concept and the promise is exactly what I and many others want and need, but the execution falls short. For the nerds and the developers if they're reading: the system on the surfaces tries to embrace the "Component" pattern but under the hood uses a lot of inheritance. To overcome this contradiction the asset throws more and more components to glue things together. It struggles to glue UI with controllers and resorts to providing an editor wizard for setting even small things like views or panels. Please take this as feedback from a fan and not as a critic.

I'm writing this review after spending HOURS trying to integrate this system into my existing project. I really hate to say it, but this asset is a mess. The developers claim this is a "flexible" system, but in reality, it's a massive system with many moving parts that are highly coupled to one another. IT WILL BREAK YOUR PROJECT. PERIOD. The simplest thing, such as trying to use your existing input system configuration, requires digging through one of the worst documentation I've ever encountered, and I still couldn't get it done before giving up. Most of the time, you'll end up guessing rather than understanding what is going on from the docs. Not worth it. Especially not for the price of $90. Avoid.

Not the most intuitive, but support is great!

Sadly i expected the asset to be better documented. The videos are from a old version and scripts have changed names since then. also it never really explains topics deep, just mentiones some parts and then moves on. as this asset claims to be working for a lot of different needs, there should also be some explanations for different setups. the asset could be probably a nice asset, but the time you have to sink into reconstruct how to use it makes it not worth. there is a discord and a forum and the dev answers questions within two days, so thats good. didnt help me really tho be aware that there is no networking solution with this and i would cost a lot of manual work to get it running. in the forum there have been topics that there was the idea to add, but it is not and seems to be not intended.

Modular, versatile and great asset. Don't waste time building your own inventory system, use UIS instead, it handles all the heavy-lifting while granting you the ultimate freedom of customization. ✅ Publisher responded and guided me on how to get support. Old Review: Asset is versatile and great but the Discord "support" is useless. I'm not the kind of person who asks for support via reviews but this publisher's support is horrible. I only asked simple questions like, "Can I use Ultimate Inventory as backend and build my own UI from scratch without using the current templates or UI schema." and got no response. I asked because I wanted a RE, Tarkov-style tetris inventory UI which I'm not sure the system fully supports. It does support custom shapes and sizes but I don't think you can rotate (which could frustrate players). I've also asked questions about their other assets like, "What's the maximum number of agents Behaviour Designer Pro can handle" and no response either. If you're fine with the publisher ignoring you after purchase, this asset is definitely for you.
